in the form of a dorsal flexion of the wrist - that obviously leads to the storage of elastic energy and induces the stretch reflex. This mechanism contributes considerably to high velocities of the racket at impact esp. in world class tennis (over 30 m/s for the gro-undstrokes and the ...
The results suggest that material characterisation testing to a maximum strain of 0.4 and a maximum rate of 500 s−1 in tension and to a maximum strain of −0.4 and a maximum rate of −800 s−1 in compression would encapsulate the demands placed on the material during impact and, ...
