选取12名一级和二级男子大学生游泳运动员,通过对蛙泳划臂、蹬腿和配合技术产生的推进力与蛙泳技术动作周期进行测试,以此探讨蛙泳分解技术和配合技术的动作周期、推进力与运动成绩等参数之间的关系。研究结果表明:水中模拟蛙泳的划频、划幅技术参数值可反映出实际蛙泳的技术指标水平;一级和二级运动员各技术环节产生的推进力差异不大,划臂技术动作周期的差异和配合技术的划幅是影响二者运动水平的主要因素。 12 first and second-level male college swimmers were selected to test the movement cycle of breast stroke by using the propulsive forces caused by the stroke, stroke and coordination of breaststroke, and to explore the action cycle of breast-stroke decomposition technique and cooperation technique, And sports performance parameters such as the relationship between. The results show that the parameters of stroke-strikethrough and swath technique in water simulating breaststroke can reflect the technical indexes of actual breaststroke. The propulsive force produced by each technical step of primary and secondary athletes is not different, And with the technical sketching is the main factor affecting their level of exercise.
