The Influence of Grip Position on Upper Limb Contributions to Racket Head Velocity in a Tennis Forehand

摘要: In tennis groundstrokes, the speed of racket head depends on rotational velocities upper limb segments and corresponding instantaneous position racket. The method holding may influence these factors. Six high-performance players who preferred eastern a further 6 western were filmed. displacement histories 16 selected landmarks calculated using direct linear transformation approach used to calculate contribution that three-dimensional individual segment rotations for made velocity. Horizontal flexion/abduction internal rotation arm, in addition velocity shoulder, primary contributors at impact, regardless grip. Significant variations, however, recorded hand different grip positions.
