公安院校学生运动性疲劳敏感指标筛选与分析

Construction and Analysis of Exercise-induced Fatigue Sensitivity Index of Police College Students

采用文献检索法、Delphi法、整群抽样法得到14个具有监测意义的公安院校学生运动性疲劳敏感指标,通过RPE评分值将某公安院校100名学生分为4组,对指标进行T0和T1时间采样,并进行对比。结果表明专家咨询结果可靠,公安院校学生运动性疲劳的发生以基础心率、睾酮、皮质醇、睾酮/皮质醇、血红蛋白、红细胞、纵跳高度、睡眠质量的变化为敏感指标,运动后心率恢复时间、血乳酸水平、血氧饱和度、尿液指标和白细胞计数等指标在Delphi法中得到了认可,但统计学意义不明显。利用公安院校学生运动性疲劳敏感指标可预警学生的运动性疲劳,提高公安院校体能技能训练水平和预防学生运动损伤。

Using the literature method, Delphi method and cluster sampling method, 14 sensitive indicators of sports fatigue of college students in public security universities with monitoring significance were obtained. According to the RPE scores, 100 students in a public security college were divided into 4 groups. The indicators were sampled at T0and T1 time for comparison. The results show that the results of expert consultation are reliable;the occurrence of exercise-induced fatigue in public security college students is sensitive to changes in basal heart rate, testosterone,cortisol, testosterone/cortisol, hemoglobin, red blood cells, vertical jump height, and sleep quality;indicators such as time, blood lactate level, blood oxygen saturation, urine index and white blood cell count have been recognized in the Delphi method, but the statistical significance are not obvious. It is suggested to use the sensitive indicators of sports fatigue of college students in public security colleges to warn students of sports fatigue, and improve the teaching and training level of public security colleges and prevent injuries.
