Biomechanical analysis Of A Tennis Serve

Biomechanical analysis of three tennis serve types using a markerless system

PurposeThe tennis serve is commonly associated with musculoskeletal injury. Advanced players are able to hit multiple serve types with different types of spin. No investigation has characterised the kinematics of all three serve types for the upper extremity and back.

Methods Seven NCAA Division I male tennis players performed three successful flat, kick and slice serves. Serves were recorded using an eight camera markerless motion capture system. Laser scanning was utilised to accurately collect body dimensions and data were computed using inverse kinematic methods.

Results There was no significant difference in maximum back extension angle for the flat, kick or slice serves. The kick serve had a higher force magnitude at the back than the flat and slice as well as larger posteriorly directed shoulder forces. The flat serve had significantly greater maximum shoulder internal rotation velocity versus the slice serve. Force and torque magnitudes at the elbow and wrist were not significantly different between the serves.

Conclusions The kick serve places higher physical demands on the back and shoulder while the slice serve demonstrated lower overall kinetic forces. This information may have injury prevention and rehabilitation implications.

Need help with biomechanics relating to tennis serve? | Yahoo Answers

You should think of yourself as a spring when serving.
You want to twist your trunk to the right (if you're right handed), bend at the knees, and start the backswing in motion.
As the racquet starts to move up, you push off with your bent legs, twist your trunk to the left, and whip the racquet through the point of contact using your wrist to get some snap on the racquet.
I'm not sure if this is exactly what you're looking for, but those are the basic biomechanics.
