摘　　要：目的:探究在30 s温盖特蹬车测试前对下肢股四头肌和腘绳肌进行高能激光干预对下肢无氧功率产生的影响。方法:采用随机分组的方式将山东体育学院20名健康的运动训练专业大学生分为空白对照组和实验组,通过在温盖特实验前进行高能激光的干预,分别对比实验组与对照组在运动后的峰值功率、平均功率、相对峰值功率和相对平均功率,探究高能激光对于下肢无氧功率的影响。结果:运动前使用高能激光进行干预后可以提高肌肉收缩做工能力,提高无氧功峰值功率。实验组与对照组比较具有显著性差异(P<0.05),并且对相对平均功率和相对峰值功率也有明显的提高,其中相对峰值功率出现了显著性差异(P<0.05),但相对平均功率没有显著性差异。结论:运动前使用高能激光可以提高无氧峰值功率与相对峰值功率,对无氧做功能力具有提高的作用。Objective:To explore the effect of high-energy laser intervention on quadriceps femoris and hamstring muscles before 30 s Wingate pedal exercise on muscle anaerobic power.Methods:Randomly divide 20 undergraduates majoring in sports training from Shandong Sport University into 2 groups:control group and experiment group,and the experiment group got the intervention before Wingate experiment while the control group did not.Compare the indicators of the 2 groups after exercise,including peak power,average power,relative peak power and relative average power,to explore the influence of high-energy laser for lower limb anaerobic power.Results:The intervention with high-energy laser before exercise can improve the muscle contraction and improve the peak power of anaerobic work.The experiment group and the control group were significantly different(P<0.05),and the relative average power and the relative peak power were also significantly improved,with the relative peak power being significantly different(P<0.05),but not the relative average power.Conclusion:The use of high-energy laser before exercise can improve the anaerobic peak power and relative peak power,which can improve the ability of anaerobic work.
