The
following video is a comparative serve analysis of Andy Roddick and
other world class tennis players. The video examines the
physiological characteristics required to streamline performance.
The
key points of the video include:
- Shoulder range of motion (external rotation ≥ 50°, Roddick = 130°) is of great importance, allowing larger generation of racquet speed.
- Sequential activation of the muscle groups allows for efficient transfer of momentum resulting in enhanced racquet speed and maximal ball displacement.
- Of importance is hip drive/rotation, a component of all mechanical throwing and hitting actions. Limited hip drive and rotation observes a noticeable decrease in performance due to the break in the kinetic chain.
Ignoring
the product placement... and utilising this movement knowledge, we
can then implement corrective techniques and sports specific
programming to enhance these skills ultimately improving sports
performance. Some examples could include PNF stretching to increase
or maintain shoulder range of motion and a one armed low to high
cable press accentuating leg drive and hip rotation.
Roddick has one of the fastest ever recorded serves because of highly efficient
biomechanics, as evident in this video.
Thanks,
