    1) What is Ultimate?

    Ultimate is a fabulous, high-energy sport that can be enjoyed by people of all ages and disc-skills who don't mind a little running and a lot of fun. The description below applies to the outdoor version of the game. The indoor version, being on a smaller field, is somewhat modified (a slightly smaller field and fewer players) but mostly similar.

    Picture, if you will, a playing field (usually grass, but desperate teams will play on almost any surface) as follows:

         <- 25 yds -> <--------------- 70 yds --------------> <- 25 yds ->
       ^ +-----------+---------------------------------------+-----------+
       | |           |                                       |           |
       | |           |                                       |           |
    
       | |           |                                       |           |
       | |   End     |                                       |   End     |
      40 |           |                                       |           |
      yds|   Zone    |                                       |   Zone    |
       | |           |                                       |           |
       | |           |                                       |           |
       | |           |                                       |           |
    
       | |           |                                       |           |
       v +-----------+---------------------------------------+-----------+
    

    On this playing field are two teams of seven players each. The object of the game is for a team to pass the disc from player to player, all the way up the field, and catch the disc in their end- zone, which scores a point. Players cannot run with the disc, but must plant a pivot foot (as in basketball) and throw the disc to a teammate. When holding the disc, a player gets ten seconds to throw it to a teammate (five or seven seconds indoors), which is counted off by the defender guarding the offensive player (known as "marking" the thrower.) If the disc isn't thrown in time, it's called a "stall" and the defense takes over.

    If the offensive team drops the disc, catches it out of bounds, or failes to complete a pass because a defender somehow blocks the pass, the other team picks up the disc where it lands and works to score in the other direction. Defenders gnerally play either a man-to-man or zone defense in their attempt to block a throw.

    The game is non-contact - it's a foul to hit the other player, or to hit the disc while it's being held. (Blocking the disc right after it's thrown, known as a "point-block", is a very hot play!) Nor can a defender be "picked" off the player being guarded. Any play carried out with the main intent to prevent another player from having a fair chance at catching the disc or making a defense is considered a foul; in other words, you have to "play the disc, not the person!"

    Probably the most important part of Ultimate is known as "The Spirit of the Game". This catch-phrase is used to describe the respect that every player in the game has for his fellow players. No referees are used in the game. Instead, each player does his best to make an honest call if necessary, and trust the calls of his fellow players, with the implicit assumption that nobody in Ultimate would try to cheat.

    This principle is what makes Ultimate special to so many people, and all Ultimate players try to keep the Spirit alive by maintaining this high level of trust, no matter how competitive the game gets. If people cannot resolve their differences, people usually say "back to the thrower", which allows play to continue on without forcing the issue one way or another.

    The best way to see how Ultimate is played is to go watch a local tournament. Ultimate players share a great comraderie, and LOVE to introduce new players to the sport. So come on out and watch!

    Organizations supporting Ultimate competition are the Ultimate Players Assocation (UPA) and the World Flying Disc Federation (WFDF ). The UPA is a United States organization which sponsors a club competition series in the fall and a college competition series in the spring.

    The WFDF runs their championships in even numbered years. Each country gets to send one team - and it can be a club team (e.g., the US sends its champion), or an all-star/select team (which almost every other country does).

    In odd numbered years, they run the WUCC - the World Ultimate Club Championships, where each country is allowed to send a specified number of existing club teams. So, many "real" teams from countries, versus a single select or put together team for the WFDF championships.

    2) What is Disc Golf?

    Disc golf is a great sport for everybody that relies on one's ability to throw a disc with power and accuracy. People of any age, ability, and gender can excel and enjoy disc golf immensely.

    The object of the game is to traverse a course from beginning to end in the fewest total number of throws of a golf disc. Similar to the traditional golf game, a course is composed of a number of holes, in which each player begins by throwing from the tee, and completes the hole by landing in or striking the target.

    The total score for a course is determined by totaling the number of throws made on each hole. The winner is the player who completes the course in the fewest number of throws...or whoever has the most fun!

    Disc golf courses exist in many different terrains. Often they are laid out among wooden areas, with water hazards, large elevation changes, and difficult throws. Other courses are mostly flat, with few natural obstacles. The obstacles should be considered part of the course, and not tampered with (even when a tree eats your disc!)

    The average course is 18 holes, but 9 hole and 27 hole courses exist as well. The average hole is around 425 ft (130m), but some are as short as 150 ft (45m) or as long as 1000 ft (300m). Courses usually have a listed par, for pro or amateur players. Of course, people practice disc golf all the time by just aiming for an object a hundred yards away, which is the kind of disc golf one will often see being played on university campuses or urban parks.

    Terms:

    Tee -
    this the area where the player starts each hole. Some courses have multiple tees for each hole. The material on the tee surface varies from concrete, asphalt, dirt, crushed stone, or wood chips. In general, any flat non-slippery surface is good.
    Target -
    The target is where the disc must land in in order to complete the hole. The target is usually a "pole hole" which is specially made to catch the golf disc. Courses that do not use pole holes are usually known as object courses. A typical "object target" is a tree trunk, 4x4 or pipe.
    Golf disc -
    a "golf disc" is a flying disc made especially for the sport of disc golf, although some players use Wham-O type frisbees. Golf discs vary in weight and size. They are usually harder and denser than Wham-O type frisbees. Special models exist for driving, putting and "up shots" (not as far as a drive, but more than a putt) much like different golf clubs exist in ball golf. However, players are not required to use a "driver" as a driver or a "putter" as a putter. Some players throw a putter as their first shot from the tee. A golf disc generally costs anywhere from US $5-7, depending on how many are bought.

    A professional PDGA tour exists, currently has about 5000-7000 active members, some of whom play on a professional level for money, and some play on a amateur level for non cash prizes. The top money winner last year won over US $16,000.

    3) Is there an FTP site for Disc stuff?

    We assume everyone reads the newsgroup rec.sport.disc for basic information about disc sports.

    A new anonymous FTP site for Ultimate information has been set up. This new site (ftp.hacks.arizona.edu) supersedes the Wisconsin and Rochester sites (thanks to Gary Lewandowski and George Ferguson, who maintained them). You may download copies of various rules via anonymous FTP from:

    ftp://ftp.hacks.arizona.edu/pub/ultimate

    In order to reduce net bandwidth, the contact information is no longer being distributed with the FAQ, and is only availible via FTP or mail-FTP. All of the files are kept to a managable size to prevent mailer-death.

    Anyone without FTP access should look into using ftpmail. See the FAQ for comp.archives available from rtfm.mit.edu in the /pub/usenet/comp.archives directory. (Yes, you need FTP access to get this document.)

    For information about all that's at the Ultimate FTP site, see: ftp://ftp.hacks.arizona.edu/pub/ultimate/INDEX

    The following files should be available there (among others):

    6) Am I eligible for Collegiate Ultimate under the UPA?

    [ The original version of the following was written by Frank Revi on August 29, 1992 when he was UPA National College Director. The current director is 74404.753@compuserve.com (Jay Cohen), who added a few changes.]

    The following is a SUMMARY of UPA college eligibility requirements. It is intended to give an overview of the requirements. It is not the full text, and therefore DOES NOT give definitive information for all cases. The official text as published in the UPA newsetter pertaining to the season in question is the only source of official documentation of the eligibility rules for that season.

    All questions on eligibility should be addressed to the National College Director. "Rulings" from other coordinators and UPA headquarters staff are not final.

    UPA college eligibility is a 5-year window during which a player may participate in the series. The window runs continuously from the player's first participation in a UPA sanctioned event or first UPA membership, whichever comes first; but no earlier than the date of high school graduation (i.e. UPA events/membership while in high school don't count). The window closes annually on 1 June. The intent of this rule is to only allow players with less than five years of experience to compete at college level. The player must further meet the following requirements:

    * Be registered and enrolled in a regularly matriculated degree program at the institution for which s/he is eligible to play

    * Be taking a minimum of two full-time classes during the academic period(s) containing both March 1st and May 1st of the current year (must be at least a half time student).

    [The above requirement is waived for students taking the minimum required academic load required to graduate at the end of the academic period containing May 1st. Research and thesis work may be counted towards the required courseload IF it is officially recognized as equivalent by the institution (e.g. if you register for research in the equivalent of course hours, that counts). Any questionable situations require a clarification request (see below).]

    * Be a member of the UPA in good standing

    The UPA does not grant exemptions to the eligibility rules.

    In cases where the rules are not clear, a clarification request may be made in writing by returning an official form by the deadline published in the newsletter. Forms must be requested in writing from UPA HQ; directions are printed on the form. Requests are reviewed by the Coordinating Committee and responses are mailed.

    The eligibility of all players on a given team must apply at the same branch or location of that school.

    Teams must submit completed rosters signed and sealed by the registrar before playing in any series event.

    7) How is the UPA Top 25 List Computed?

    The UPA Top 25 is calculated by Eric Simon and distrbuted weekly. However, the Top 25 isn't accurate unless college tournaments call in their scores! So, please, all college teams and tournament directors should send in their scores to Eric or the UPA (see FAQ.2 for a contact list.)

    The most basic explanation of the Top 25 rating system is this: for each game a team plays, the team gets rating points. These rating points are then averaged.

    The next level of complexity is how to compute the points for a given game, and how to avereage them. The points for a given game is given by this formula:

            pts = opp_rate + (400 / x)                           (1)
    
    where opp_rate is the rating of the opponent, and x is a factor that depends upon the score. The formula for x is:
            x = max(.66,(2.5*(losing score/winning score)^2))    (2)
    
    Rather than explain it, let me give an example. Suppose team A beats team B 15-11. According to the formula, take the fraction 11/15, square it, and multiply by 2.5. This gives us 1.34. Suppose, further, that team B has a rating of 1000. According to formula (1), we simply compute 1000 + 400/1.34 and get 1298. The "max" that's used for formula (2) makes it so that the smallest that x can equal is .66, which means that the best (or worst) a team can do in a specific game is to perform at 600 points better (or worse) than their opponent. (A score of 13-5 will get you 600 points).

    So, suppose team A has played in 4 games, and each individual game rating is 1298, 913, 1410, and 1103. Well, we simply average them together, and team A has a rating of (1298+913+1410+1103)/4 which is 1181. But, actually, the averaging isn't quite that simple, either. We actually take a weighted average. In the above example, each game had a weight of 1, in actuality, the weight depends upon how recently the game was played. This formula is:

            wt = min(1,1/(((today-gamedate+4)/7).4))            (3)
    
    Suppose games were played on four consecutive Saturdays. Since the ratings are done on Mondays, this would mean that the games were played 2, 9, 16, and 23 days ago. Well, by formula (3), any game played within 3 days of the rating gets a weight of 1. Games played the week before, or 9 days ago, get a weight of 1/((9/7)^.4) which is about .9. The games 16 days ago are weighted at about .72, etc. This is called a decay function, and, basically, it means that the more recent the game is, the more heavily it is weighted.

    Finally, whatever the weight it, it is doubled for games at Regionals, and tripled for games at Nationals. After all, teams are usually at full strength during those tourneys, and the games are more important. Finally, it is hoped that the winner of Nationals will come out as number one in the rankings. Luckily this has always happenned, although one year a team that lost in the semifinals almost finished first.

    But that's not all! Suppose the ratings of the teams you play change. An underated team you lost to in the first round ends up winning the tournament. Should your rating reflect that teams' victories, in other words trying to take into account that the other team was a really good team. Of course it should. Suppose your team's rating went up during the course of the tourney, too; shouldn't other teams, in turn, get the benefit of that?

    This is done in an interative process. On Monday, every team gets re-rated. That is, we recompute every individual game rating, based on the previous week's ratings, and the new date. Then, each team gets a new rating for the current week. Then, we re-rate every team again, using this week's ratings, to get a new set of ratings. We do this 20 times (this is why a computer is indispensable). Eventually (usually after only about 8 interations) the ratings reach some sort of equilibrium. It's kind of a neat process to watch. If some team does really well, and the rating goes up 250 points, then, on the second iteration, all teams that have played the first team goes up by a smaller amount, and on the third iteration, all the teams that have played the teams that played the first team will go up by a small amount, and so on.

    The biggest problem with the system is that in some areas of the country not everyone is calling in scores. Let me give a classic example of how an entire region can be adversely effected by this.

    Suppose the best team in Region X always calls in their games (and, in fact, more winners than losers call games in). So, suppose this team "State U." calls in 13 games of theirs, all victories. None of the other teams had called in any scores. This team beat, say, team B in the finals of two other tournaments. Obviously, team B must've been pretty good to make it to the finals, but to the computer, team B was simply 0-2. In fact, to the computer, it looked like the 13-0 team was playing a really wimpy schedule because every team that had played was winless! So what happens? State U doesn't get a very high ranking. Now, weeks later, the other scores are called in. It's too late, State U is already ranked lower than they should be, and all these other schools are, correctly, ranked lower than State U is. So, the whole region gets ranked lower than they should be.

    8) What's a MAC, and how do I do it?

    A MAC, also known as a "mack", actually stands for Midflight Attitude Correction. In the sport of Ultimate, it usually happens by mistake, but here's how to do it on purpose.

    To MAC a disc effectively, one needs to be aware of the direction of spin the disc has. The two possibilities are clockwise (originating from a standard backhand throw from a right-handed player) and counterclockwise (a sidearm throw from a right-handed player).

    The best throws to MAC are hard with lots of Zs (spin). The technique is to allow the disc to be throw at you very hard, allow the disc to pass you, the MACer, on one side of your body or another, and just as the disc is perpendicular to the throw line, touch the side of the disc very briefly.

    If the throw is clockwise, allow the disc to pass your right side (as you are looking at the thrower) and tap the top of the disc's platter, near the outside of the disc at the point closests to you. The disc will then take a MAC, climbing upward. If the clockwise throw passes on your left, that tap will send it straight into the ground.

    Switch everything around for a counterclockwise throw. Disc passes you on the left, tap the side of the disc, it takes a MAC and climbs up. Disc passes on your right, tap it on the side, the disc dives down into the ground.

    There are some neat variations of the MAC, like the foot MAC, which takes some extra practice. Hitting the disc on the outside edge from the thrower is also harder. If you want to see one of the best MACers alive, watch Dan (Stork) Roddick sometime. He is amazing! (he is also the Sports Director for Wham-O). And no place is better to MAC than on a California beach somewhere.

    Some work has been done on converting discs into interesting weapons, by using the disc to launch either a flare or a hand grenade; these are discussed in some of the above messages.

    Apparently, the patent applications from Wham-O in the late 1950's are interesting reading material. See the patent section of any well-stocked university library for references in this area.

    frevi@athena.mit.edu did work as an undergrad (MIT) involving the visualization of flow around a rotating frisbee using dry ice vapor as the tracer aerosol and stroboscopic and conventional photography. In particular, a number of photos were taken of vapor flowing around a disc mounted on a motor in various orientations, the trajectory of a frisbee throw through a sort-of stationary flow field stopped stroboscopically, and various multiple exposures of throw/release motions. The results of the flow studies seemed to indicate that a rotating frisbee induces lift independent of a trajectory vector; i.e. the disc doesn't have to be going someplace to generate lift, just spinning.

    medf214@chpc.utexas.edu (Aaron Altman) did some interesting work analyzing the behavior of a disc in a wind tunnel, with specific regards to the so-called airbounce. He examined the effects of windspeed and angle of attack [alpha] on a disc. From his messages, slightly edited:

    After performing many wind tunnel tests on an old, wasted Wham-O, I measured the effects of varying angle of attack and windspeed. It was difficult to determine the rate at which an average disc is spun, so this part of the experiment is very much "up in the air". There was also no way to simulate the initial "throw", or accelleration of the disc, so all of these results examine the disc under a constant windspeed, which ignores all of the interesting things which happen to the airflow around a disc as it is thrown.

    The simplest visualization for the results is to draw the analogy between an airplane on approach to landing, and a disc at high alpha. Increasing the angle of attack increases the induced drag (or resulting drag force), but enables the disc to fly slower while still flying in the same flight path. The airflow on the top of the disc is usually not "attached" fully, inplying a turbulent, vortical, unsteady, non-laminar flow. The same is true for an airplane on approach to landing. The airplane reduces its speed, but the flight path is maintained (within a certain range) by increasing the alpha of the plane. In an airbounce, some extra lift is generated from the so-called "ground effect" as well.

    This experiment gave no data on the limits of the ground effect. However, the limits are determined by the amount of wing loading, so one can guess from experience with other flying objects. For example, the ground effect for a Cessna 172 tends to be approximately 1/2 the span the wing, which is s approximately 20 ft. This causes the airplane to float above the runway at speeds lower than would normally be possible for this airplane. From discussions of the ground effect with pilots of larger airplanes, such as the Boeing 727, this equation (1/2 span) doesn't hold as well, and the ground effect tends to be between 1/2 and 1/3 span. At any rate, that brings us back to the disc...If we took 1/2 the span of the disc, this would place us somewhere about 6 inches off the ground.

    So, what does this all mean? In terms of flight dynamics, the small displacement given to the disc by the thumb at the last second causes the leading edge to rise. This, in combination with the large, instantaneous, simultaneous forward force of the throw, (called the impulse,) creates a high angle of attack flight regime, with the possibility of an increase in altitude, depending on the actual angle of release from the hand (angle the arm makes with horizontal upon release of the disc, not the same as displacement given by the thumb.

    Of course, if all of this is true [and it may not be!] it should be possible to throw a disc at high alpha, without the angle imparted to the horizon by the arm, and still have an airbounce. This would result in a disc flying without a change in height, but with a large angle of attack. This would imply that, not only is it necessary to apply thumb pressure, but the angle of release is also quite important in establishing a true airbounce.

    Given all of this, one can describe the physics required to throw a disc that goes down and then up. The follow-through on the throw would be downward, but the force applied to the disc in that instance is applied just below the horizontal (say, between -3 to -8 degrees). This force will cause the initial trajectory of the disc to be slightly downward. After some distance, the component of lift generated by the forward motion of disc (at alpha) overcomes the initial slight downward component given in the initial release of the disc. In studying the problem as a thin airfoil (using thin airfoil theory) this can be shown to be possible quite trivially.

    When a disc is thrown, it undergoes an initial acceleration that is quite large. Once released, the speed decreases as a result of viscous losses due to the friction of air. This change in speed results in a highly unsteady problem (which changes as a function of time). By analyzing the lift force and drag force (Cl, Cd respectively) at many different windspeeds and alphas, a profile of the behavior of the disc as its thrown can be examined, with Cd and Cl increasing essentially linearly with alpha.

    In addition, I would like to comment on some info included in the most recent version of the FAQ. As determined by my experimentation, the component of lift generated by a stationary disc, spinning, is extraordinarily small when compared to the component of lift generated by the forward motion of the disc.

    This is with reference to the work done by frevi@athena.mit.edu. The information that he obtained was strictly qualitative, and the quantitative data that I obtained tells me that a spinning disc (without a directional component) generates very little lift. A good physical analogy would be to say that if this were true, than this aspect of lift would be exploited in modern lifting bodies, lending creedence to the possibility of flying saucers!

    * Whew * People interested in more detail, or interested in using this as a "grossly understudied...killer thesis topic" are encouraged to contact Aaron directly.

    11) Footwear
    a) Nike Sharks, etc..
    b) Survey.
    b) Mail Order.
    c) Bunions and Shoes.
    There are a lot of shoes out there, and a lot of opinions about them. Models of shoes come and go, opinions change. I've included some excerpts from discussions of the topic. New information, especially if summarized, is welcome. Generally, you want to consider durability of the shoe and cleat, how hard the cleat grabs, high-top or low-top, overall comfort.

    a) Nike Sharks, etc.

    Phillip N Price writes: Many players like soccer-style shoes, which do not have cleats at the edges of the shoe and which (usually) have cleats that are circular in cross-section. I don't like those shoes (they make me feel wobbly), so I don't use them and can't recommend one type over another.

    I favor shoes that have cleats all the way at the edges. The edge cleats are generally rectangular in cross-section, perhaps with some odd-shaped protruberances. Inner cleats may be round, triangular, or other, depending on brand.

    Of this latter type, the premier example used to be Nike Sharks. Available in high, mid, and low-tops, these were the shoe of choice among Ultimate players when I started playing in the mid 1980's. Unfortunately, the method of joining sole to upper was changed around 1990 or 1991, and the new method is not nearly as reliable---I, and most of my Sharks-wearing friends, were plagued by "blow-outs" (separation of sole and upper at points of high stress), and I no longer wear Sharks. [Also, they've gotten much more expensive than they used to be.]

    After trying several types of Sharks-type shoes, I've settled on Reebok Pit Bulls as a replacement. These are very similar to the original Nike Sharks, are relatively inexpensive, and are fairly durable.

    Thomas Griesbaum writes: The Land Shark model was really durable: stitches would last and most important the cleats would not break. Some time later the Boss Shark was introduced (with a red/black sole). With most shoes exposed cleats (depending on your running style) would break and I also saw problems with stitches and even other parts of the shoe tearing.

    Maurice Cinquini writes: Beware, in my opinion, use of sharks and other shoes with extra grip and large leverage on ankles contribute to the large number of knee and ankle injuries we have in the sport. The other major factor is the `cuts' players are encouraged to do. New players especially, have not had the time to strenghen the muscles to support these joints

    On 08-Mar-93 in Re: Ultimate Footware user hinkamp@cc.usu.edu writes:
    Since I'd like to see some discussion on the topic, I'll post this. I think soccer shoes are the perfect shoes for ultimate. Infact I'd like to see the UPA limit legal footwear to molded type soccer cleats. Soccer leagues limit toe cleats for the same reason the UPA should, they are a hazard to players. Some of the football and "shark" spikes woren by players now are a hazard in close play (i.e. stepping on and kicking people). my only problem with soccer cleats is that I have not found a good high top pair.

    [Replying to the above:] Oy vey! After a year of foot cramps, blisters and shin splints caused by (some fairly expensive) soccer cleats, I finally found podiatric bliss in Nike SHARKS and you want to take them away?!? My girlfriend has said I have, and this is a direct quote "the feet of a beast" (I won't mention what she thinks of my table manners). She's right, though. They're flat as boards. Almost splayed. They are architecturally unsound. Those big, wide SHARKS are the most comfortable shoes I can find to play in.

    Seriously, I haven't found them to be more or less dangerous than other shoes. It's FEET that do the stomping, not shoes. Molded soccer cleats can hurt a hell of a lot if they stomp on your foot, and I would argue that the cleats on the SHARK are a little softer and less harmful than on many soccer shoes.

    Dennis mentions that soccer leagues limit toe cleats, and I think that there's a good reason for that, but it doesn't apply to ultimate. Soccer players use their feet to kick, as well as run. That's why so many of them wear shin guards. On the soccer field, a toe cleat IS a potentially dangerous weapon. Not so in ultimate. The only comparable action I can think of in ultimate is the footblock, and this is a dubious example, at best. Everyone in soccer kicks. RELATIVELY few of us footblock. In soccer, players often try to kick into the same space at the same time (at a moving target, no less) The potential for an accidental kick is very great. As we all know, in ultimate, optimally, this should not happen with foot and hand. A legal (and effective) footblock should never occupy the thrower's hand space, but a space about a foot (no pun intended, I mean twelve inches) upfield. We all know that this doesn't always happen, but the footblock debate is apparently one that doesn't need to be revived. In the latest survey report, the newsletter indicated that 85% of respondents favor keeping the footblock legal. The upthrust of all this is simply that I don't think the soccer ban on toe cleats is all that relevant when applied to our sport.

    Of course no one would favor metal cleats, and if you're gonna have screw-ins, the screw has to be in the cleat, not coming out of the shoe (so as not to leave a deadly spikey protrusion coming from the sole in the event of cleat loss), but aside from that, I suggest, with all due respect to my fellow disc players who disagree, that the shoe situation is fine as it now "stands."

    Subject: Shoes for ultimate survey summary
    Summary: Results of survey of Ultimate shoes
    Date: 1 Jun 92 19:32:20 GMT

    The replies to my "shoes for ultimate" survey seem to have trickled to a halt. Here is the summary I promised. I didn't receive enough replies to justify drawing hard conclusions. In addition, I unfortunately slanted the original article toward a particular brand and model of shoe, which may have colored the results of the survey.

    The following chart is an attempt to summarize all of the positive and negative comments at a glance. A notation such as "+n" indicates that n people found these shoes to be desirable in this characteristic, "-n" indicates that n people didn't like it. I included trimmed down copies of the original posts, because shoe analysis seems to be a subjective thing, and this should help people interpret the results.

    Specific replies follow:

    [...] I can identify a brand name that produced some shoes similar to what you described. I bought some out of curiosity last fall and loved them except for one caveat. If the ground is the least bit wet they muck up very quickly and feel like lead boots. I'd recommend carrying different shoes (like Sharks or soccer shoes) in the case that the ground is wet. The shoe I got is a Converse (Hi-top model).

    =====================
    My first cleats were Patrick soccer cleats. 'nuff said. :-(.

    Before my ankles finished falling off, I bought Nike (Land) Sharks, vintage 1990. They were a problem for me because (i) the toe is too pointed, making a hard cut a somewhat Procrustean experience (but most people don't have this problem); and (ii) the lugs were too soft, and in a year (playing 3-5 hrs/wk.) I had snapped off four or five of the big ones.

    When the problem became too serious to ignore (no lugs on medial right heel), I threw 'em out and bought Pony Blasters. I liked these better than the Sharks, as they fit my feet well and the lugs were stronger (and well-placed); however, they didn't have much padding.

    Eventually the Ponies wore out and I bought (on clearance) a pair of Converse Starforce hightops. The grip is good (but the fields I play on are now so hard that it hasn't been tested well); however, after about 10 hours of use the leather has split on the medial left heel, which bodes ill for their longevity.

    ========================
    [...] I will tell you what type of shoes I wear. I bought a pair of Adidas Stratos Drive at the beginning of this year and they are great. They have long studs, which are recommended for soft ground, but I think that is because they are soccer cleats and soccer players must kick that ball. I haven't had any trouble with traction and actually find that I get better traction than with any other cleat I have worn. The cleats have only six studs, two in back and four in front. All the cleats I have worn in the past have had something like 10 or 12. The six studs really don't pick up any mud, and therefore don't bog down in mud. They are also hard plastic, so they "dig in" in hard ground. They are by far the best cleat I have ever worn. I ran into a problem with my other cleats of wearing out after only one year or so, but these are showing absolutely no sign of wear. They also have removable studs, so that you can put in shorter ones if you like or replace the ones in there. They cost around $65, but I think they are an excellent deal.

    I haven't tried a football cleat but I can't imagine anything working better than the Stratos Drive. Oh yeah, I almost forgot one small point in all my rambling. The Stratos Drive give me a significant jump. Because there are only 4 studs in front, I get excellent grip on quick accelerations. I was immediately able to get a great jump on even our fastest players after getting these cleats. But you probably should have strong ankles if you get these because they are a little hard to get used to.

    =====================
    [Ed note: I stopped in at the Nike store in downtown Portland, Oregon (Nike is based in the Portland area). A sales clerk told me that the Nike Land Shark was no longer made. It is possible that between between me and the clerk some information was garbled, but this agrees with what I heard in local shoe stores. I have been trying several times a day to call Nike's Consumer Information Center (1-800-344-NIKE) to check out this report and track down some Nike Land Sharks, but the phone is always busy. They must be swamped with customers clamoring for the old Land Sharks :-)]

    =====================
    The most common shoes on the Portland team are probably Nike Air Slams. They are actually softball shoes but they have better traction than anything else that we have tried. The cleats are hard plastic -- they have a lot of "bite" to them but they clog easily in mud. Unfortunately softball is not exactly a high intensity sport so Slams don't have much foot, arch or ankle support. I know two people who have gone back to Sharks because they got tired of having their feet hurt all the time. Blake Garnard (who plays for Rhino Slam) wears Sharks most of the time and only puts his Slams on for semis and finals! I've never had any pair of cleats last me more than about a year, but the Slams have been pretty tough.

    Compared to Sharks, the Slams have better traction and seem to be tougher, but the Sharks give better support and work a little better in the mud. If you are going to use either Sharks or Slams and you play in the mud then it's a good idea to get some standard soccer type cleats for mud and use the other pair in dryer conditions.

    I know a number of people at Nike including several who play Ultimate. I was talking to one of their R&D people (who plays Ultimate) last week. He says that Nike considers Ultimate to be a "closet sport" and as such they don't do any R&D for it. Nike doesn't make any shoes that are ideal for Ultimate but Sharks are probably the best overall match to our sport out of their line.

    I've only had one pair of cleats that weren't made by Nike. They were made by Converse but I can't find a model name or number on them. I've only worn them twice. The back of the heel has a hard plastic piece inside it and it isn't the same shape as the back of my heel. [...]

    =====================
    [A reply to the above:] The type of earth you play on can make a difference as well. I've never played on the west coast, but in Florida and North Carolina the dirt is very sandy and has a lot more give to it than the topsoil of the Midwest. It can make a difference in the ideal shoe (I use Air Sharks, BTW, and am quite happy with them - bought them about six months ago and they're holding up fine)

    ======================
    I just got a new pair of Nike Shark high tops this week. (btw I have not found *any* source of high top shoes in Manitoba - had to get these brought in from New York). They are indeed too hard and slip on the hard ground here. My favorite Ultimate shoe for dry ground is a Spot Bilt turf shoe (no high top available unfortunately), I don't know the exact model name. this shoe is great for hard ground or good grass, but the small cleats hold too much mud when its really wet.

    ======================
    [A reply to the above:] Amen! These were/are my favorite ultimate shoes I ever had. But I don't think they exist anymore -- no shoe salesperson here in SillyPutty Valley could locate them. If anyone has any source for these, I'd *love* to know where to get some.

    Last year I had a pair of Umbro cleats (molded); I loved them, but as one of the earlier posts mentioned, they changed them this year, and they seem a little narrower, especially at the toe. Still, they're pretty comfortable. I played with a pair of Patrick molded cleats this spring, and found them quite good, but I'll switch to the Umbros for summer, as the cleats are shorter, and we play on a lot of dry, hard fields.

    I have found one particular mail order company to be pretty darn good. Their catalog is very nice. The offer a wide variety of soccer cleats(sorry no Nike-Sharks) and a veritble plethera of other soccer stuff(shorts, shirts, extra shoelaces, etc.) The prices are a little on the high side but the best part is the offer overnight delivery for only $2.00 above the normal shipping costs.

    The also offer a passback program. If you have cleats that you no longer use ,but are still usable then you can return them tand get a $5.00 credit on your next cleat order. The cleat you returned will then be given to poor kids all around the world(mainly for soccer).

    The name and phone number of this company is
    Eurosport
    1-800-934-3876

    I am not a representative of this company just an Ultimate player who likes their service. Just give them a call to get the catalog and check through it.

    c) Shoes and Bunions

    I've worn Adidas soccer shoes for many years and have been happy with them. However, a year ago I had to give up the inexpensive kind that are mainly nylon with only a little bit of leather at crucial wear points and switch to the all leather kind that cost four times as much. The reason was that as I played harder, the force of my foot shifting in the shoe caused too much force on the nylon, and that stress had to be absorbed by the outside "knuckle" of my big toes. This led to painful bunions that were immediately alleviated by the leather shoes that absorb more stress and distribute it more evenly over the foot.

    I've always worn low-top shoes, but it took about 3 years of playing before my ankles got strong enough to get through a game without swelling up afterwards.

    a) Pain and Painkillers

    At one time or another, people on the net have been posting discussions about pain - playing in pain, dealing with pain, playing while doped on various drugs, legal and otherwise, etc.

    A few notes, gathered from various doctors and experienced Ultimate players who deal with doctors:

    1. Pain is your friend. If you feel pain, it is a sign that you should slow down...or stop.
    2. Ignoring pain generally leads to a more serious injury.
    3. Playing Ultimate (or any sport) while under the influence of drugs, such to the point that pain no longer is felt by the body is very dangerous.

    These remarks, people note, are often ignored by people who play professional sports. Please keep in mind, though, that the people who play professional sports usually have multiple, professionally trained individuals administering these drugs and monitoring the condition of the atheletes. Also keep in mind that these people are being often being paid considerable sums of money to play these sports...not something Ultimate is well known for.

    Other players have indicated that they regularly play after taking aspirin or ibuprofen. These drugs are noted for general anti-inflammatory benefit, but one should contact a doctor before starting a regular regemin of drug treatment, not only to avoid possible bad side-effects, but also in case a better treatment program is available.

    A last thought...there's usually only a few games a year where it's REALLY worth playing through severe pain. Most people are better off missing a few practices due to some sort of injury than risking it all for the sake of an extra week of practice. However, everybody has to judge for themselves how bad an injury really is and what it's worth to you and your team to stay on the field.

    b) General Injuries

    People who play Ultimate see plenty of injuries. The general treatment for just about any sprain, strain, muscle tear, etc, is RICE, which stands for Rest - Ice - Compression - Elevation. First, get off the injury. Then, 15-20 minutes of ice in an ice bag, wrapped around the injury, while elevating the injury above the level of the heard. If the injury seems exceptionally severe, the best thing to do is see a professional about it.

    For injuries which are a result of the chronic wear and tear that Ultimate can give to the body, a general ice-massage is a good idea after practice and games. As a matter of fact, old and new injuries alike feel much better if ice is applied shortly after the conclusion of the workout, not to mention controlling swelling. An excellent way to make ice-cubes is to purchase some paper cups, fill them about three-quarters full of water, freeze, and then to peel the paper down from the top. This way, you have something to hold on with your hands, and you can massage the injury directly with the ice, probably the best way to apply ice. Be careful of frostburn if applying the ice directly to the skin.

    Seeing a doctor who specializes in sports for any serious injury is highly recommended...it's amazing what a special stretch, brace, or tape-job can do for an injury which otherwise ruins your playing enjoyment, especially with respect to those nagging injuries which seem to never go away. And it's never too late - if you sprain and ankle and find that it's still not quite where it should be two or three weeks later, a good sports-therapist can offer invaluable advice towards rehabilitation of the affected member.

    One reason some Ultimate players tend to avoid the doctor is their afraid the doctor will tell them to stop playing Ultimate, which we all agree is a Bad Thing. Fortunately, many doctors who specialize in sports-medicine don't like people to stop what they're doing, except for a short period of time to let things heal. Clearly, a sprained ankle or strained shoulder needs a few days to start the healing process, but after that, it's often possible to resume playing (carefully) with some medical assistance.

    c) Tape and Braces

    Lots of times, people will beg, borrow, or steal the brace of a fellow Ultimate player, or ask a friend to "tape them up" when they're really don't quite know how to do it.

    As with using painkillers on a regular basis, it's a good idea to see a professional before starting to strap a brace on all the time. Sometimes the cause of pain isn't what it seems...and a brace can help or * hurt * the problem. The same is true for a tape-job. It can make all the difference in the world to an injured body part, but the wrong taping job can really screw a joint up.

    Learning to tape yourself isn't too hard though, since you'll probably get tired of going to somebody for help all the time. If you need the same type of taping job regularly (as is usually the case) ask somebody who knows how to do it to teach you and a couple of your teammates, practice, practice, practices, and then start taping yourself. After all, you're the best one to know when it's too tight and when it feels right.

    If you really mess up your knee and have a serious brace prescribed, make sure you select as good an apparatus as your circumstances permit. Take time to look over what is available, talk to other players with similar injuries. A well-fitted, lightweight brace will not interfere with a high level of play.

    d) Shin Splints

    A fairly common injury that shouldn't be allowed to ruin your play. Shin splints are usually the result of a lot of pounding on feet from continual running, jumping, and other types of Ultimate activity. The causes can be traced back to lots of things, including the type of cleat, running surface, running style, proper muscle balance, and lack of proper stretching. They usually occur in people who radically change their workout schedule over a short period of time; ie, suddenly playing Ultimate every day after several months (years?) of inactivity.

    Once you get them, they often return, so people who get shin splints need to take certain preventative measures to strengthen the area and minimize the possibility of recurrence. This includes stretching and exercising the muscles in the front and back of the lower leg.

    One easy exercise is to stand in front of a wall or bookcase or something you can hold on to for balance. Without shoes on, alternate pulling the balls of your feet up off the floor until you can't do it anymore. You should feel it working the muscles next to your shins. Another exercise you can do at home is calf raises. Start doing them with your feet flat on the floor, then work up to doing them with your heels hanging over a step. Do them slowly! Stretch before and after!

    A good stretch is call the "alphabet stretch". Simply sit down, cross one leg over the other so that your ankle can move, and then, as if your big toe was the point of a pencil, make the shape of each letter of the alphabet, making sure to stretch the muscles and tendons by making your lines big. Don't make tiny letters; take your time and make your penmanship teacher proud.

    To help them go away quickly, reduce the amount of pounding on the lower legs (ie, running and Ultimate) and increase the amount stretching and strengthening. And, as always, ice is nice, along with aspirin or other painkiller (in moderation).

    A last note...if your symptoms persist or worsen, it's possible that you don't have shin splints, but have a stress-fracture or other injury instead. See a doctor, who will probably be able to help with special exercises, stretches, or orthotics.

    e) Sprained Ankles

    Another common injury which seems to befall Ultimate players, who often have to run on uneven fields. As with any other injury, it's best to ice the area completely immediately after the injury. Severe sprains can result in several days or weeks without being able to run on the ankle, so extreme care should be taken to make sure the joint heals. Once a severe sprain has occurred, the joint will probably be vulnerable thereafter.

    As part of the rehabilitation, support for the joint MUST be provided, in the form of a brace, tape, or other support, for a few months at least. Any serious sprain should be taken to a qualified doctor to make sure the injury will heal without medical intervention. The fact is that the tissue damaged in the ankle takes up to a year to grow back to full strength, if it ever does. If you consult a sports therapist during this time, he or she will give you some special exercises to build up the ankle, which will also help prevent further injury.
