4. Follow Through/Recovery
The Biomechanics involved
in a Tennis Serve
What does a Tennis Serve look like?
What is the primary objective of a Tennis Serve?
To direct the ball into the opponent's service area.
It can is also be an effective offensive weapon.
Preparation
It primarily consists of the mental set in which the athlete prepares mentally for the skill he/she is about to perform.
Head is stable & eyes are focused on the target
Right foot parallel
with baseline
Ball & racquet out in front of body
The purpose of the wind-up is to produce FORCE.
Wind-Up
Strain energy occurs since the athlete's muscles are stretched.
Strain energy is converted into kinetic energy.
Therefore, a tremendous amount of force and momentum is generated (Carr, 1997, p. 38).
The weight is initially shifted from the front foot to the rear foot.
The left arm tosses the ball. It is extended throughout the toss.
The action of the
non-racquet
and
racquet
arm is an example of Newton's third law:
'Every action has an equal and opposite reaction'
Shift of weight + bent knees = GROUND REACTION FORCE
It is initiated via the extension of the legs and the downward acceleration of the tossing arm.
Force-Generation
The ground pushes back up against the athlete.
The action of a whip.
The racquet arm is fully extended
Whip + Long lever (extended racquet arm) = Great Force
The tossing arm drops
This phase commences following contact with ball.
Follow Through / Recovery
Head is balanced & towards direction of ball
Rotation of torso
Right shoulder pointing towards direction of ball
Flexing at the knees
Racquet up & in front of body
