水中瑞士球训练对优秀游泳运动员核心稳定性与运动表现的影响

通过对18名北京体育大学中国游泳运动学院的一级游泳运动员进行陆上瑞士球核心训练和水中瑞士球核心训练，探讨水中瑞士球训练对优秀游泳运动员核心稳定性和运动表现的影响。结果表明，8周陆上和水中瑞士球训练均能显著提高优秀游泳运动员躯干力量、背肌耐力和身体平衡性，改善运动员陆上身体控制和平衡能力，进而改善游泳运动员力量传导的效率，促进躯干和上下肢之间力量的有效转移，提升打腿和划手的效果，提高50 m自由泳运动表现；两种训练对运动员柔韧性和功能性表现无显著影响；水中瑞士球训练对各测试的提升幅度和RPE强度上均高于陆上瑞士球训练，且水中瑞士球训练手段可以更有效提高游泳运动员的50 m自由泳运动表现。

Effects of Swiss Ball Training in Water on Core Stability and Performance of Elite Swimmers

This study discusses the influence of Swiss ball training in water on the core stability and sport performance by comparing the core training of Swiss ball in and out of the water among 18 elite swimmers from China Swimming College of Beijing Sport University. The results show that 8 weeks Swiss ball training both in and out of the water can significantly enhance the elite swimmers''trunk strength, back muscle endurance and body balance, improve their abilities of body control and balance on land, thereby increase their efficiency of power transmission and promote the effective transfer of strength between the trunk and the upper and lower limbs, boost the effect of kicking and stroking, and improve the 50-meter freestyle swimming performance. Both trainings have no significant influence on the flexibility and functional performance of athletes. But the Swiss ball training in water leads to higher improvement and RPE intensity in each test than the training on land; and the Swiss ball training in water can more effectively improve the 50-meter freestyle performance of swimmers.
