The purpose of this study was to analyze the influence of footwear on the kinematics and the mechanical load on the lower extremities during fast lateral movements in tennis. The method used was a prospective study. Two types of tennis shoes were randomly distributed among 229 tennis players. The subjects were measured before starting a 3-month test period. The study showed that the kinematics of the lower extremities and internal load conditions during fast lateral movements in tennis are highly influenced by the type of shoe worn. The results further suggest that a prospective biomechanical analysis can be used to establish assumptions concerning the etiology of pain and injuries in sports related activities.
