Men's Report: USA-USSR Dual Meet

By Robert Cowan USGF Men's Program Administrator

Any objections the Men 's Program Committee had voiced about competing with the Soviet Union due to lack of opportunity to

learn, were erased April 23 during the McDonald 's Challenge: USA/USSR competition.

With excellent training sessions both before and after the competitions, with the use of compulsory exercises to pick the USA squad and with the genuine cooperativeness and friendli­ness of the Soviet coaches, judges and athletes, this was a great step in our preparations for September in Seoul.

In an interview with a Phoenix paper, Alexei Tikhonkikh, the Soviet great who became the alternate at this year's event was quoted as saying "gymnastics is serious fun." There are volumes in that one simple sentence. The Soviets do not seem burdened by the moral conscience of most Ameri­cans. In other words, they never thought twice about making every ef­fort to win every event, every medal.

The U.S.'s highest finish was a fourth place final tally in compulsories by Dan Hayden and a fifth place finish in optionals by Scott Johnson. Yet , even then the Soviets seemed unsatis­fied with the results .

Not the cold, uncaring automatons the press and other athletes have por­trayed them to be, we witnessed Leonid Archaev, the Soviet national coach wrestling with Yuri Korolev two­time world all-around champion and all-around champion of the 1988 USA­USSR dual meet. The Soviets enjoyed meeting the L.A. Lakers, and they genuinely enjoyed laying around the pool soaking up Arizona rays and sign­ing autographs for the young female groupies which inundated the hotel.

It is always difficult to equate how realistic scores are in a dual meet, as the usual games are played . The Soviet judges did not write down one thing, rather watched as interested tourists the routines and then flashed

a score, sometimes with apparent sig­nals of ear touching, head genuflection or other attempts to communicate. However, in the opinion of all who were involved, the scoring was very ac­curate in an international way. Certain­ly higher than the USA, but one the less realistic in terms of international scoring .

COMPULSORY SESSION

The USA improved the com­pulsory team score from Rotterdam by almost 7 points and even if this as doubly more than realistic ,

3.5 in Rotterdam would have moved the team up four places. Overall , the

USA has improved tremendously but still notably deficient in several areas. Some of these areas are simple to cor­rect and hopefully with the input of Abie Grossfield, Mas Watanabe and the knowledge gained from studies of the films of the Soviets, this will be done by September.

Floor Exercise-The biggest differ" ence here is the rhythm with which the Soviets work. The U.S.'s backhand­springs appeared to be shorter and choppier than the Soviets. Also, the ex­tension of the legs, toe point, and the power into and out of certain skills and entire passes was more noticeable. Other areas: The Soviet's planche down to the splits from the handstand; they are more erect with their posture

Tom Schlesinger, who was recently the recipient of the 1987 Nissen Award, was part of an overall good performance by the Ameri­can squad against the Soviet Union.

and U.S. scales are piked somewhat, where theirs are fully extended.

Pommel Horse-The most notice­able difference here appeared to be Soviets swinging bigger than the Americans. Also, the Soviets were more square before and after skills. In other words, each skill looked finished. It had a definite beginning and ending, where the USA skills appeared hur­ried, cut off and even shrunk. This "BIG" swing appears to come from swinging higher (from the chest) and their shoulder flexibility seemed very apparent on this event. Also, they are looking further out when they swing. NOT UP, but out. In other words, if a gymnast of equal height from the hands to the head were swinging, their focal point might be 7 feet from the horse, and the Soviets might be 9 or 10 feet from the horse. Also, when their legs are split, they are "VERY" split. I feel this is strength, not flexibil­ity which allows them to carry the split position through the skills.

Still Rings-This is probably the event where the biggest difference

Technique

shows up, both compulsory and op­tional. Notable differences: the strength in the front lever; the straddle "L" was not held, but simply shown VERY well ; the swing in the front gi­ant was not labored, but very quick; they do use wide arm bails, even though we are told these are to be deducted; the swing through hand­stand positions was very precise and definite with a infinitesimal pause pri­or to dropping or bailing; their inlocate was more like a giant rather than a backrise hand and their entire swing was bigger or rounder, not elliptical.

Vaulting-The big difference here was the apparent opening of the vault prior to landing. However, of the six guys who jumped, there were at least three different and noticable tech­niques. However, the best vaults demonstrated a tuck, then an opening through a pike in the chest, then a. definite pike, then a stretch, then a stick on the landing. There was an ex-

treme FAST opening of the legs. The best example of the manner in which the body opened is a New Year's Eve noisemaker which rolls out when air is blown into out and then curls up when finished.

Parallel Bars-This was the event, where the U.S. is closest to the Soviets. Highlights of the Soviet 's rou­tine were: a. jump to near 45 degrees on the mount b. mount with straight arms near handstand c. double leg cut is LOW and locks in with NO movement. U.S. is high and sometimes the kids dip (0.1-0.2) d. straight arm peaches, EVERYONE e. back rise hand into the pirouette is smoother, faster and totally non­appearing to have strength . The Soviets keep their chest down or "in" on this skill.

Horizontal Bar-The biggest differ­ences here are that the Soviets hit EV­ERY handstand possible in the routine. It appeared that their swing is more el­liptical at the ending of each skill, rather than circular. For example, on the weiler kip, it stalls at the top then kips in . It almost looked like parallel bar swinq . Also, the dismount is a mid-

It was nice to see Tim Daggett back and competing during the closed compulsory ses­sion. For his pommel horse routine Daggett scored a 9.75.

saito twist. The Soviets set off the bar, twist, spot the floor for brief instant and then stick.

In an interview with the New York Times, the reporter asked if I thought our team was intimidated or scared. It answered firmly and with conviction, "NO". However, after a few of our guys had committed errors and knew that they were going to be knocked out of the optionals, the wind appeared to go out of them. This bothered me. As a team, every man has to compete 100 percent, regardless of whether his per­sonal goals are no longer attainable. The Men's Program Committee had made this event a qualifying meet and ALL who went into optionals qualified.

OPTIONAL SESSION The optional session was one of the

best in which the USA has appeared since 1983, when the USA beat the Soviets in Florida.

Starting on floor exercise, the USA team hit all six routines with only a line fault deduction for Kevin Davis who did a 112 turn prone out of bounds. Valeri Ljukin attempted this famous triple and opened early and earned 9.45. Korolev went 10.0 with a great routine and Ar­temov was second at 9.9. Team score after floor was USSR-49.20 and USA 48.30. The 0.90 difference was about what had been expected.

Pommel Horse was the best event of the night for the Americans with all six men hitting and Belozerchev falling on on his 4th D! The difference in team score was 0.20 and the USA was 1.1 behind after two events.

Still Rings as mentioned earlier is the U.S.'s nemesis as the U.S. simply does not have the strength and Soviets and other nations have. They are ex­tremely strong, despite being so thin. Their arm muscles are almost un­noticeable. They give the appearance of having swimmer's smooth muscle. The exception is of course, Belozer­chev who is built like a freight train . However, the USA dropped only 0.85 to the Soviets as the team performed extremely well , hitting all routines and with few steps on dismounts. Lyukin and Belozerchev tied at 9.95 but Lyu­kin's routine was the best. Back kip to planche, bounce to cross (flawless),

back kip to "L". Press to handstand, back giant, back giant, guczoghy, whippet, swing h.s.; Layout full out, stick.

Vaulting was another event in which the U.S. competed very well (0.7 be­hind the Soviets) but how realistic this would be in the Olympics or World Championships is uncertain. Two vaults are 9.4 vaults and yet received 9.65 and 9.55 respectively. Also, Mike Rice and Korolev did the same air-walk layout Tsuk with the noticeable differ­ence being Korolev's form, distance and the fact that it is really a 9.4 vault which scores 9.90! With the code hav­ing 4 vault tables (8.7,9.0,9.3 and 9.6) the I:J.S. better have all 9.6 vaults in the future .

Parallel Bars continues to be an event where the U.S. needs to spend a lot of time. Not only on technique, difficulty and swing, but also on prepar­ing the bars. It took as long as one minute per gymnast to prepare the rails. This needs to be cut down to 20-30 seconds very soon. Chaplin led off for the USA and broke on his se­cond healey, receiving a 9.1 . Korob­chinsky went 9.8 for the first Soviet routine, and Holdsworth (USA) took steps on his dismount to go 9.45. Novikov went 9.85, Rice answered with a stuck set at 9.65. Korolev and Davis went 9.9 and 9.85 respectively. The scores continue to see-saw back and forth with the Soviets always get­ting a 0.1 more. In all, the Soviets defeated the U.S. by 0.925 on this event. All together the meet lasted 3'/2 hours and unlike the China dual meet

in 1985 which went five hours, this one was friendly in appearance. Most nota­ble routine was Belozerchev's 10.0 performance of Straddle cut mount, flairs to straddle planche, straight arm peach to glide, swing to handstand, healey, back stutz, but to "L", Press­back toss, back toss, pike double STICK.

Horizontal Bar was a great finale with the only break being Mike Rice missing a yeager and scoring 9.25. The Soviets outdistanced the Ameri­cans by 0.85 and scored two 10's, a 9.95, a 9.90 and 9.85. The USA high score was Dan Hayden at 9.90 with a great routine, much improved on the Kovacs and a step on the dismount. Notable routine was Korolev who mounted stemme piroutte, 1 arm giant, 1 arm tkachev, kip change to jam to in­verts (2), yeager, kip hop and layout 1/1 out.

Final score was USSR-295.65 and USA 291.175.

A major improvement and consider­ing that Tom Schlesinger and Charles Lakes were not in the line-up also gives hope to increased improvement by the Olympic Games.

A goal has to be for the USA to fin­ish in the top six in compulsories and hopefully hang on to stay in the top six. The U.S. MUST improve over the past two international efforts which results in a 9th place finish.

Finally, it was good to see Tim Dag­gett up working (he did pommel horse in the compulsory meet) and aSSisting Head Coach Fred Roethlisberger and Bill Meade in the optional meet.

The Biomechanics Of Release - Regrasp Skills In Gymnastics

8

By Hardy Fink Department of Physical Education

University of British Columbia

The recent evolution of release skill on horizontal bar has generated considerable interest in how each of these skills is per­formed. It has also somewhat concealed the fact that release skills are regularly per­

formed on various other men's and women 's apparatus.

The profusion of release and reg rasp skills in gym­nastics has been so extensive that it would require volumes to describe and explain them all. It is far bet­ter to thoroughly understand the few underlying prin­ciples and then apply them to the study of existing skills of interest or possible innovations.

As the name "release-regrasp" suggests each of these skills has several parameters each of which must be understood: 1. Release phase 2. Flight phase 3. Regrasp phase

Release Phase The most important determinant in th~ successful

performance of these skills is the "Release phase" or, perhaps more precisely, the "moment of release. " It is during that phase and at that moment that each of these critical parameters is decided. 1. Trajectory and path of the centre of gravity

a) angle of release (of C. of G.) b) possible angle of regrasp (of C. of G.) c) vertical velocity d) horizontal velocity e) height f) distance g) direction

2. Time in the air 3. Angular momentum of the body

a) moment of inertia about the axes b) angular velocity

Even without discussing these parameters in depth (many of them are interrelated) it follows that if a per­formance error is identified as involving anyone of them , then the error was made during the "release phase." Most of the errors that we attempt to correct in the "flight phase" are only symptoms of a release error. In all cases that release error is one of incorrect force application because the characteristics of the ap-

plied force (magnitude, direction, point and/or time of application) during the "release phase" completely determine the characteristics of the subsequent "flight phase."

More specifically - and this will become clear in the ensuing discussion - three biomechanical concepts are crucial to the "release phase." These are: 1. Transfer of angular momentum 2. Action - reaction 3. Reaction force

These three are interrelated in the sense that the ex­istence of one implies the existence, usually, of the others. For this discussion the interaction of these three concepts requires external contact - in fact only "action-reaction" of the three can occur without ex­ternal contact. 1. Transfer of angular momentum

A strong flexion or extension at the hips (for ex­ample) creates considerable angular momentum (AM) in the legs. If the legs are then suddenly stopped it can be said that AM will be transferred to the total body.

2. Action-reaction Assuming the body is free of external forces or

of external contact then a strong action (i.e ., lifting the legs (hip flexion) will have the effect of causing the torso also to flex towards the legs as a reaction.

3. Reaction force In external support situations the reaction to the

action (i.e ., lifting the legs) is restrained because of the contact. This will cause a force to be applied in the direction of expected reaction at the contact point or surface. The contact surface responds with a reaction force in a direction opposite to the applied force .

All "release-regrasp" skills can and should be analyzed during the release phase according to the interplay of these three concepts as the following ex­amples should illustrate:

The Tkatchev This contemporary skill , though conceived in 1969

and first performed in 1975 is still of considerable in­terest and is still poorly understood.

Prior to discussing the critical components necessary for success it should be mentioned that the swing parameters must be optimized . 1. The Tkatchev is initiated with a strong extenstion at

the hips (leg extension, frames 2-4). This relates back to the three concepts as follows:

Technique

Page 9: Technique Magazine - June 1988

I •

a) The strong leg extension introduces a component of angular momentum in the forward rotating direction. When the extension stops just prior to release at about frame 7 or 8 that component of angular momentum is transferred to the whole body in the desirable forward direction.

b) The strong leg extension results in a concommit­tant hyper extension (reaction) in the upper body and arms. This reaction however is restrained by the contact with the bar and serves therefore as a downward force on the bar.

c) The downward force on the bar is accompanied by the desired upward reaction force of the bar at the point of contact (the hands) . This serves to raise the body of the gymnast vertically and also, because it is applied far from the centre of gravity, serves as a torque which causes forward rotation during the "flight phase."

The Jaeger The Jaeger saito was first performed internationally

in 1974 in the form shown below: 1. The Jaeger similarly to the Tkatchev, is initiated with

a strong leg extension at the hips (frames 3-6). Again this relates to the three identified "release" concepts as follows:

Technique

)

a) The strong leg extension introduces a component of angular momentum in the forward rotating direction. When the extension stops (around frame 6) that component of angular momentum is transferred to the whole body in the desired for­ward direction.

b) The strong leg extension is accompanied by the reaction of an upper body extension but this is restrained by the contact with the bar, and there­fore acts as an approximately upward directed force against the bar.

c) The force applied against the bar as a result of the reaction to the leg extension action results in the bar exerting an equal and opposite reaction force: In this case directed downward. Since it acts far from the centre of gravity it serves as a torque which gives the body additional forward angular momentum during the flight phase.

Flight Phase The flight phase in all skills including the Tkatchev

and the Jaeger is relatively easy to understand because all of the parameters critical to success have been de­termined during the release phase.

In most cases, and it is evident in these two skills ,

the body should be relatively stretched at the moment of release (large moment of inertia) . This permits the body to be piked and straddled in the air which causes an increase in the angular velocity of the gymnast such that the skills (which both require considerable forward rotation) can be completed.

Regrasp Phase If the skill has been performed well then the gym­

nast will have time to stretch again prior to contact (frame 19 Tkatchev; frame 12 Jaeger). This has the ef­fect of slowing down the speed of rotation (angular ve­locity) and allowing the gymnast to control the reg rasp and to reduce the jerk often seen after a regrasp.

A II gymnastics skills that involve a "re­lease phase" or a "takeoff phase" should be analyzed in tis manner in order to understand how the skill should be per­formed. Some practice with sequence

photos or drawings should help coaches become profi­cient at this form of analysis.

It is possible to work backward or forward in the process of analysis. For instance working backward, one can determine that it is important to generate for­ward rotation and then identify the reaction force that will serve as a forward torque; then the force applied to which the apparatus reacted; then the reaction of the body that created the applied force; then the ac­tion to which the "contact end" of the body reacted. In most cases this action also serves to transfer angu­lar momentum in the desired direction to the body.

Working forwards one can follow the steps as illus­trated here for the Tkatchev and the Jaeger.

Many of the present generation of "release and regrasp" skills and all of the next generation of such skills will require maximum reaction forces from the ap­paratus. To create these the initial body action (i.e., hip extension, etc.) must be maximally strong and must cre­ate maximum angular momentum (fast and stretched!). Stated in another way: For each of the three concepts of transfer of angular momentum, action-reaction and reaction force the gymnast must be able to generate enough power (fast force) in the major muscle groups and to do this with maximum extention of body parts (good form). To achieve these results it is important for the gymnasts to have undergone excellent physical and technical preparation. It is not the impressive "flight phases" that are difficult; it is generating correct forces in the "release phase" that is. Only by concentrating on and understanding that phase can our frequent "fright" elements become the flight elements we desire.

Running Technique For Vaulting

By Jim Holt University of Washington

The potential effectiveness of any vault is largely predi­cated on the quality of the run. Obviously, the faster the gymnast runs in his

approach, the greater the force he generates as he makes contact with the vaulting board, and the greater the postflight height and distance. While recently a significant amount of literature1 has been directed at step sequence and other forces generated at the hurdle, there has been little com­mentary in the gymnastics communi­ty on the running techniques which enable a gymnast to attain maximum speed.

Speed in running is the product of length of stride and stride frequency. "Running speed is completely deter­mined by just two factors. Stride length(SL) and stride frequency(SF). The product of these two factors is equal to the speed. For example, an athlete with a stride length of seven feet and a stride frequency of five per second is running at 35 feet per second. Speed = SL x SF

= 7 feet x 5 per second = 35 feet per second." 2

Therefore, the ONLY way in which a person can improve running speed is by improving one or both of these factors. The techniques of sprinting must be rehearsed at slow speeds and then transferred to runs at maximum speed. In this sense, sprint training is directly related to gymnastics as an ex­ercise in motor learning. Stride length can be improved by developing mus­cular strength, power, strength endur­ance, and proper running technique. 3

It should be noted that flexibility is an important component of the physical preparation for running due to the im­portance of appropriate range of mo­tion on technique.

The first step in developing a gym­nastics sprint program is to instruct gymnasts on the correct techniques of running. Efficient technique maximizes

18

stride length and allows development of stride rate. Watching videos of track and field athletes such as Carl Lewis or Daley Thompson is an easy way to illustrate proper technique to gym­nasts. Sprinters run with the head neu­tral and with a slight forward body lean. The amount of forward lean will be contingent on acceleration. The facial muscles and jaw should be relaxed. The hands have thumb and forefinger touching, and the other 3 digits curled and relaxed. The hand should be open

(as opposed to a fist) . These elements keep the musculature in the chest and shoulder girdle relaxed, and allow the arms to swing freely and powerfully through their full range of motion.

As the arm swings forward, the knuckles of the hand should lift to chin height. The arm bend between the

Technique

Page 19: Technique Magazine - June 1988

forearm and the upper arm creates an angle less than 45°. On the back­swing, the elbow is at shoulder height and arm angle should open to 90°. Also, the direction of the arms should be directly forward and backward, like pistons. The elbows are in close to the body and the arms should lightly brush the lats. The hands should not break the plane of the body. Any deviation from this will create an automatic body compensation that will retard the de­velopment of speed. For example, when the left arm breaks the plane of the body on the front swing, a common compensatory motion is a lateral exter­nil whip of the lower right leg.

Gymnasts should note the interrela­tionship between arms and legs in run­ning. As an athlete strides forward with the leg, the opposite arm will swing for­ward in synchronization. Therefore, the more powerful an arm swing, or longer the range of arm motion, theo­retically the longer the stride length will be. It is vital then, within currently known parameters that gymnasts not compromise arm action on their vault­ing approach. Conversely, when run­ners utilize faulty arm swing, the mechanics of the stride of the legs are directly (and of course adversely) af­fected either by a shortening of the stride or its rate.

The knees should lift to hip height during the front part of the stride. The lower leg does not fully extend at ground contact and the ball and then the heel should make contact, not vice versa. The trail leg extends fully, driv­ing powerfully off the foot and upon release from the ground, the heel kicks powerfully up into the gluteals/but­tocks. This is the key body action since the heel kick will a.) throw the femur forward, and thereby increase the stride length due to the action/reaction transfer of momentum, and b.) allow the leg to move more quickly to the shortening of the radius during the for­ward swing.4 Therefore, the greater and more powerful the heel lift, the longer the stride.

It is important that the legs (as the arms) drive straight forward and not move laterally. Additionally, the feet should be pointed straight ahead and the legs should be in a forward direc­tion during the stride. The heel kick should also extend straight up and down. The contact with the ground is a rolling action on the balls of the feet. While there have been great sprinters with idiosyncratic styles (Bob Hayes and Elry Hirsch come immediately to

Technique

mind), it is imperative to recognize the impediments to speed development that faulty mechanics entail. 5,6

While we have largely confined our­selves to the mechanics of the stride "during the run," the start should be examined as well. While it is known that optimal velocity can be reached in 12-13 strides7 , the sooner a runner reaches top speed, the potentially more powerful the vault. This relates to the theoretical application of power as it pertains to the alactic nature of the punch and block phases of the vault.s The most effective means of getting into a stride quickly from a standing p0-sition is a "rocking step" in which an athlete shifts his weight from a back leg to a front leg while simultaneously swinging his opposite arm. Unlike sprinters, gymnasts cannot take ad­vantage of starting blocks; unlike dis­tance runners, we have the advantage of not having to initiate our run in response to a starting gun.

Since a gymnast knows which is his first step, he can put that foot back, shift his weight, and synchronize his arms so that he can drive into his stride on the first step rather than take sever­al steps to accelerate into a run; a vaulter who does not rock into his first step is largely wasting the first 3-4 steps of his run!

There are many drills that can be used to enhance technique and to de­velop stride length and cadence:

1 . Heel kicks: The heel kicks are the single most important sprint exercise.9

Gymnasts should run at 1/4 to 1/2 speed taking relatively short stride lengths but emphasizing lift of the heel; for pur­poses of the drill, hitting the buttocks with the heel is quite acceptabe; em­phasis is placed on a quick, powerful lift off the ground, but attention can also be paid to proper arm swing.

2. Running in place with tubing: gymnasts in this exercise can concen­trate on technical aspects of striding as well as the cadence. Because of the phenomenon of synchronization, if one speeds up the arm action, the legs will automatically increase their rate. Be­cause a gymnast is running stationary, he can be placed in front of a mirror where he can actually see his tech­nique. Stationary running is an excel­lent way to not only work on technique, but to attempt to increase stride rate. Because stationary running heightens a gymnast's awareness of the syn­chronization between the arms and legs, speeding up the arm action (by moving through an increasingly

smaller range of motion) will increase stride rate.

3. Little feet: although the possibi­liy of significantly increasing stride rate is disputed10 by many track and field experts, exercises that emphasize this element of running are included in most contemporary sprint programs. This drill exclusively focuses on rate; over a 40-50 foot length, a gymnast runs as fast as he can taking the smallest steps possible; also, em­phasise very quick, small arm swing (the hands will move in small circles).

4. Running downhill: is a relatively controversial exercise, whose intent is to increase stride rate. Incline should be no more than 5 0. This is not consi­dered a good exercise for young ath­letes due to the stress on the patellar tendon on impact.

5. Running backwards: an excel­lent drill for emphaSizing heel lift and technique, gymnasts should run back­ward at half-speed, lifting heel to gluteals and reaching or "crabbing" backwards with the lower leg, and lift­ing elbows high at the end of the backswing.

6. High knee kicks: promote stride lengths by emphasizing the lift of the floor and the power kick in the front part of the stride.

7. Stag leaps (also called Bound­ers): is the oppOSite exercise to Little Feet; an athlete attempts to travel us­ing the fewest number of strides pos­sible. In this exercise, he exaggerates the left off the back leg and the knee kick on the front side to create the lon­gest possible stride.

8. Power Skips: is an exercise com­bining High Knee Kicks and Bound­ers: a gymnast should skip with exag­gerated arm swing on both sides and high knee lift to create a long, power­ful skip; the skip with the lead leg should be a quick thrust forward.

9. Frog Leaps: develop strength and power in the front quadriceps; this relates exclusively to development of stride length; CAVEAT: this exercise should be approached with caution by children due to the stress put on the knee joint.

10. Running Stairs: is a time­honored means of developing power and strength in a stride; adolescents should not use this particular exercise due to stress on the achilles on ascent and jarring of knees on descent. Addi­tionally, there is some evidence that Osgood-Slaughter's can be aggravat­ed by such an exercise;ll stairs should be avoided until the epiphesis of the bones close.

lation between the power generated in the run and the postflight height and distance on the vault. It is therefore vi­tal to the outcome of the vault to de­velop proper running mechanics and the concommittant strength and pow­er to maximize running speed . This in turn entails a reassessment of the preparatory phase of an annual train­ing cycle as it pertains to vaulting . By adapting the techniques, drills, and body of information already estab­lished through track and field studies, vaulters can build a foundation which will ultimately advance the limits of the event.
