Swimming speed influence factors contribution research based on biomechanics and fluid mechanics analysis

Abstract

Swimming is a sport that attach equal importance to endurance and techniques, sound techniques ensures scientific exert, make analysis of swimming techniques from fluid mechanics and biomechanics perspective can put forward more objective suggestions to swimming and make contribution to swimming technical rationality and improvement direction. Due to swimmers suffer gravity and water acting force in swim-in process, how to improve propulsion force and decrease resist force is the purpose of problem research, this paper based on the analysis of swimming process starting technique, propelling technique and turning push off such three technical features, apply fluid mechanics and biomechanics theory to make analysis of swimmers arms stroke propelling effect, leg kick propelling effect and trunk movement propelling effect, make quantitative analysis of biomechanics features in arms stroking process, make qualitative analysis of leg kick and leg drive propelling effect conditions as well as trunk deformed propelling contribution conditions to different swimming way. Through research method, analysis line and research results from this paper, reasonable suggestions and theoretical evidence are put forward to swimming techniques.
