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.

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.
