Abstract


Since the beginning of the 21st century, mingled with a variety of play style, table tennis competitions confrontational is getting stronger ball turn more and more, the technical requirements of the athlete's range of movement, direction and more refined , makes the athlete's footwork has become one of the main factors in determining the results of the competition. Footwork as the life of the sport, have a crucial role in the completion of the entire swing and reasonable to complete the action, the validity of the scientific. Scholars table tennis footwork techniques did not go deep into the inherent laws of Table Tennis footwork the lower extremities action technology, more table tennis footwork from the teaching and training methods, by virtue of experience, continuous exploration and improvements. This article aims to apply Biomechanics Principle, three table tennis footwork - stepped from the three aspects of the kinematics, dynamics and plantar pressure, in-depth study, and step-by-step and cross step foot movement biomechanics law The main conclusions are: 1. the forehand stride forehand and step batting form of movement of the foot in the ground after exerting force foot similarity; backhand stride backhand and step-by-step and hitting backhand cross step foot development effort The form of foot movement similarity; hitting a three-step action force pedal stretched form of exercise has a foot off the ground when the similarity. By three-step action, athletes completed cross step vertical ground reaction force peak force and force loading rate, and the maximum force foot, ankle the joint flexion amplitude and Achilles tendon angle variation, so athletes frequent crossover step-by-step method may increase the probability of the occurrence of foot fatigue damage. 3 three-step action, hitting force foot vertical ground reaction force by the peak force, the foot are in them the flip motion before and after the maximum valgus angle, plus maximum back of the ankle increase flexor state, so the probability of occurrence of the ankle injury. 4 feet of table tennis footwork typical action process plantar pressure bearing area focus on the front foot area the uneven force evident enough in the zone. District plantar pressure after batting force foot foot peak cross the step-by-step method, and step-by-step method, followed by stepping footwork minimum. Suffered plantar peak pressure in the forefoot area for the front foot zone is more stable force area, outside of the forefoot area and the forefoot medial area the size of the action in the form of footwork.
