Biomechanics of movement(a lower body sport)
Friday, March 30th, 2007Coaches have always been interested in the biomechanics of the swing…i.e pronation, elbow position, size of backswing, correct grip choice, lining up the butt face, contact point etc….. but, what about understanding the biomechanics of movement and the importance of balance in tennis. I believe these two vital areas need to be TAUGHT, studied and understood more!
Just because you can run fast doesn’t mean you move fast on the court! Speed comes from efficiency of movement, balance, good anticipation, competitive greatness and mastering movement mechanics SPECIFIC to tennis. Just some of the areas that need to be realised are:
- Keeping of the angles with the legs through contact - don’t jump, or come up, finish the shot
- Use the drop step when moving to a wide ball and step out when moving short distances
- When and how to shift, pivot, rotate and transfer the weight when on the move or hitting from a stable stance
- Good use of momentum so movement flows
- Timing and selection of the correct contact move and it’s relation to strike zone and contact point
- Use of the legs in counter-balancing
- Maintaining a wide base when braking, setting up the feet and getting ready to react
- Keeping good alignment with great posture and excellent footwork to avoid reaching for the ball
- Using the side of the foot to aid recovery and knowing where the feet/hips should line up before contact
- Understanding the hitting stance, approaching ball and shot selection (attack, rally, defend) and their relation to the contact move
- Correct footwork when moving out to the ball
- Use of the ideal recovery position and timing of the split step…etc etc…the list goes on!
So, my point is….that it is important for the coach to have an EDUCATED EYE from the waist down. Tennis is a LOWER BODY SPORT. Understanding HOW the lower body must work in SYNDCHRONIZATION with the swing, grip and contact is crucial.
