SHIFT OF REAR LEG,MERITS AND DEMERITS


TENNIS SERVICE SEQUENCE, REAR LEG SHIFT.
REALLY WHAT ARE THE MERITS /DEMERITS.?
1,Stability is the prime importance before a throwing impact[service action is basically from a bio-mech point of view a throw.]
2.All the other aspects may be based on this factor,but still we can discuss ,reduction in area of supporting base may affect the[ EFFECTIVENESS OF SERVICE.]Please note there is a combination of several factors which makes a service effective.and this was discussed earlier.
3.Neuro-muscular instability caused by the shift may adversely affect the power,accuracy and spin factors of the service to delivered.
4.Instability CAUSED BY THE SHIFT may affect the quality of his capasity to face the service return ball if it comes back to his foot directly. Still we can keep listing these kind of several factors.
MERITS
To my best of ability in tthis analysis, few millimeters of height, its presumed to gain by the rear leg shift. during the impact is not a siginificant factor .We may need an extensive emphirical evidence to attribute this to effectiveness, EFFECTIVENESS FACTOR IS THE ONE SERVICE ,SENT TO OPPONENT'S WEAKNESS.
HOW TO FIX IT.
We may have to go to grass route level to add this kind of info.. at the COACHING EDUCATION LEVEL to modify the teaching lesson pattern, as well can conduct IN SERVICE PROGRAMS for the professionals already in service. Please do ask questions, my whats up number 00 91 9443424950. U can link me at facebook too. Prince jeyakumar.

DECLINE IN PERFORMANCE --HOW TO FIX IT


Due to the acyclic nature,using extreme grip pattern,surface friction,insufficient rest in between competition results in changes in the body,anterio-posterior,medio-lateral,changes in posture, lack of strength of muscle groups,leads to injury proneness,break in kinetic chain of movement,or a decline in performance in the long run. One[player/coach] may have to  understand and study the situation carefully from  a multi-disciplinary angle and tackle it. Often this is not happening with many players which results in early exits from top level competition,Some times this is happening with top ranked player of a country SAD u see, to see the level of coaching education,implimentation,kind of situation.

CAN A TECHNICAL FLAW WHICH MAY SEND A KID TO INJURY LAYOFF------YES

                       Last week I had a kind of evaluation visit  to a tennis center where my student is a chief  coach,and we have found that students as young as 12 and 14 hit very hard''HARD'' serves and often miss it too, and then they change the stance,toss and modifify serve swing, and end in a weak second serve, This is a concept error, AT THIS STAGE OF LIFE, thay fail to realize the IMPORTANCE OF EFFECTIVE SERVICE, IS THE ONE HIT TO THE OPPONENTS WEAKNESS.These kids never realize that perpectual hard hitting can land them is shoulder injuries,as well as the bio-mechnical difference the first and second serves increases the  probability of  delivering poor/ineffective serves.

HOW TO FIX IT. 1,Students should be taught all  types of services,FLAT,SLICE,TOP SPIN. with equal importance and duration.
                    2,Use appropriate MULTIPLE TYPE OF THROWING EXERCISES to reduce the throwing impact on any particular joint./group of muscles.
                    3,Should be taught how to PROGRESSIVELY  increase and reach the peak at the point of impact during serve.
                    4,Enhance the stability  of support  from the toss to point contact.

            THESE ARE PRETTY IMPORTANT, OR A PLAYER MAY RETIRE PREMATURE,

DESENSITISE CHILDREN TO ON LOOKERS' '' NEGETIVE COMMENTS''

OBSTRUCTIVE CONGESTED SERVICE TOSS AND BACK SWING MAY PROVE FATAL FOR TOP LEVEL MATCHES.:- Players may have to start a point with perfect, relaxed and with a free mind, any congested and obstructive thoughts will reduce the effectiveness of your service besides drain your capacity to handle the return of your service. Today I have seen a top player suffer from this "HYPER SELF CONSCIOUS BEHAVIOUR" and lost her match.How to fix it.This is absolutely a performance psychological situation. Appropriate expertise may have to be used. As a general advise children at the early stages of training should be given adequate chances to "desensitise" themselves to "negative comments" like poor back swing,kind of comments.

JOINT LAXITY OFTEN MIMICS AS A JOINT INJURY.

     JOINT LAXITY OFTEN MIMICS  AS A JOINT INJURY.:- JOINT LAXITY is a situation develops in a joint due to several reasons,mainly do to static stretches performed on the joint with odd angles of pull/push.,  Over loading on the particular joint due to some faulty training situation like ''EXCESSIVE FRICTION ''of the playing surface may have a direct impact on the knee joint when ever there is a twisting movement involving the ''UPPER BODY TORQUE'' Or while while you play your shot with your hips strained in a horizantal plane [due to not flexing both the knees evenly] for a low ball in Tennis.

     IN TRACK TRAINING SITUATIONS NEWLY LAID SYNTHETIC TRACK AND NEW SHOE SPIKE NAILS[LONG AND SHARP] WILL CREATE A ''ACUTE-ODD GRIP'' WITH THE TRACK FOR EVERY STRIDE AND THIS WILL RESULT IN a feeling of a apparant looseness in the joint. THIS IS A NEURO-MUSCULAR ADAPTATION and appropriate ISOMETRIC EXERCISES WILL REVERSE THE SITUATION. WITH AVOIDANCE OF LAXITY CAUSING SITUATION. I guess this applied injury causing situation is not well documented in that AREA OF  SPORTS MEDICAL THERAPY.

SITUATIONS WHICH HAMPERS THE IMPROVEMENT IN PERFORMANCE


There are several aspects contributes to this situation, I will list the prime, and most important to the least.
1. EARLY STAGES OF TRAINING DURING THE FORMATIVE YEARS LACKS TOTALITY OR NOT WELL COVERED WITH ALL THE ASSOCIATED MOTOR PAREMETERS[MULTI GAME SKILLS] CONNECTED WITH TENNIS.
2. TRAINING ON TENNIS SKILLS LIKE FH,BH ,VOLLEY,OR RARE SHOTS LIKE ROUND ARM OVERHEAD,BH OVERHEAD,OR A SOFT TOUCH DROP SHOT.IS NOT GIVEN ITS DUE IMPORTANCE,[NUNBER OF SHOTS PRACTICED] AT ALL THE STAGES OF TRAINING

3. BASIC ATHLETIC SKILLS TO DEVELOP QUALITIES LIKE
SPEED,STRENGTH,ENDURANCE,MOBILITY --NOT GIVEN ITS DUE PLACE IN TRAINING.

4.TOO MUCH IMPORTANCE GIVEN TO TRAINING GADGETS,INVOLVING ISOLATED MUSCLES/ GROUPS, AND FORGETTING THE FACT THAT EVERY SHOT IN TENNIS NEEDS WHOLE BODY INVOLVEMENT

5. SURFACE OF PLAY AND ITS FRICTION, AND ITS ADVERSE IMPACT  IS NOT WELL DOCUMENTED,ARE NOT IN THE ACCESS TO TENNIS FRATERNITY FOR REMEDIAL INTERVENTIONS, THIS IS THE CAUSE FOR TOO MANY INJURIES AND PREMATURE EXITS FROM COMPETITIVE TENNIS.
6.MODALITIES OF RECOVERY AFTER TRAINING/COMPETITIONS, NOT MANAG
7.POOR PSYCHOLOGICAL MANAGEMENT OF THE SITUATION.AFTER A CRITICAL LOSS.

HOW TO DEVELOP FOOTWORK,BALANCE,AND CORE STRENGTH IN A TALL JUNIOR TENNIS PLAYER

HOW TO DEVELOP FOOTWORK,BALANCE,AND CORE STRENGTH IN A TALL JUNIOR TENNIS PLAYER: - During early teens children experience sudden growth spurts,and show a bit unsyncronised movements,poor co-ordination and decline in performance in any sports more so in Tennis.At this stage parents /coaches may have to wait patiently and focus on basic motor qualities as well as specific game based skills so that APPROPRIATE INTEGRATION OF SKILLS AND MOTOR QUALITIES ALONG WITH ENHANCED HEIGHT AND AND WEIGHT WILL RESULT IN BETTER PERFORMANCE.By  this method better foot work,core strength,and balence also will be gained.
