无氧阈强度在武警特战队员5KM负重跑训练中的研究

Training Intensity of 5KM Heavy-duty Running of Armed Police Special Warfare Team

以庆阳市24名武警特战队员为例,随机分为实验组、对照组,用递增负荷方法测定武警特战队员的乳酸阈值,用乳酸阈强度—心率监控方法确定运动的无氧阈心率,根据无氧阈心率进行12周5km负重跑训练。试验结果显示,武警特战队员平均乳酸阈值为4.12±0.56mmol/L,乳酸阈训练强度为11.2±0.86km/h,对应的靶心率为166±18次/min。分12周的训练后,训练组最大摄氧量为51.37±2.87ml/kg/min,肺活量为4925±419ml,5km负重跑的成绩为21.11±0.46min,运动损伤1人;对照组各项指标分别为:45.19±3.63ml/kg/min,4325±405ml,23.92±0.45min,运动损伤4人;干预组与对照组各项指标在试验后均有显著性差异(p<0.01)。

This study took 24 armed police special operations members in Qingyang City as an example,and randomly divided them into experimental and control groups.The lactic acid threshold of the armed police special operations team was determined by the increasing load method,the anaerobic threshold heart rate of the exercise was determined by the lactic acid threshold intensity-heart rate monitoring method,and the 12-week 5KM weight run was trained according to the anaerobic threshold heart rate.The results show the target rate of 166±corresponding to the training intensity of 16±18 times/min.After 12 weeks of training,the maximum oxygen intake in the training group was 4925±419 ml,5km,with 121.11±0.46min,exercise injury;the control group was 445.19±3.63ml/kg/min,4325±405ml,23.92±0.45min,exercise injury;and the intervention group varied significantly after the test(p<0.01).
