不同强度蛙泳运动对中学生健康体适能的影响

Effect of breaststroke with different intensity on health-related physical fitness of middle school students

旨在探讨不同负荷强度蛙泳训练对中学生健康体适能影响因素,为提高中学生健康体适能水平提供参考。文章采用文献资料法、专家访谈法、数理统计法以及实验法等进行研究。研究结果显示,3种负荷强度组短期训练对中学生身高影响不显著(P>0.05),低负荷强度组在身体成分指标呈现显著性差异(P<0.05),中负荷强度组、高负荷强度组在身体成分指标方面相关性较低。中负荷强度组、高负荷强度组在心肺耐力指标、肌肉耐力、柔韧适能、灵敏适能指标存在显著性差异(P<0.05),低负荷强度组在心肺耐力指标、柔韧适能相关性较低,中负荷强度组肌肉耐力指标相关性较低。研究得出,3种负荷强度蛙泳训练短期内对男性中学生身高影响不显著。低负荷强度蛙泳训练降低男性中学生体重效果明显,高负荷强度蛙泳训练效果较弱。中、高负荷强度蛙泳训练对男性中学生心肺耐力适能影响显著,低负荷强度蛙泳训练对男性中学生的心肺耐力适能改善效果不显著。

The effect of breaststroke with different intensity on health-related physical fitness of middle school students was studied. It was found that short-term exercise had insignificant effect on the height of the students. The middle load intensity and high load intensity exercises had weak correlation to body composition indexes, while their effects on cardio respiratory endurance, muscular endurance, flexible fitness and sensitiveness fitness were significantly different. Low load intensity had little effect on cardio respiratory endurance and flexible fitness, while the middle load intensity was the same on muscular endurance.
