摘要
目的:探讨下肢爆发力下降率(下降成绩/训练前成绩)、体重流失率(流失体重/训练前体重)、训练疲劳积累评分(主观疲劳量表训练后评分-训练前评分)三种方法监测运动疲劳的效率.方法:以中国国家男子盲人足球队15名运动员为实验对象(国际健将4人;国家健将10人,无等级1人.年龄25.6±5.28岁;身高1.762±0.049米;体重70.93±7.61千克;BMI指数22.95±1.81;训练年限8.8±3.54年).通过实验测试获取运动员下肢爆发力下降率、体重流失率以及训练疲劳积累评分数据,然后将三项指标分别与自身血清睾酮/皮质醇(T/C值)进行相关分析.结果:运动员下肢爆发力降低率与T/C值有着近似线性的负相关关系(|R|=|-0.981|>0.70);体重流失率与T/C值存在高度的负相关关系(|R|=|-0.924|>0.70);训练疲劳积累评分与T/C有非常高度的负相关关系(|R|=|-0.718|>0.70).结论:(1)下肢爆发力下降率监测法准确度高于体重流失率与训练疲劳积累评分监测法,且体重流失率监测法效率优于训练疲劳积累评分监测法;(2)针对盲人运动员,下肢爆发力下降率运动疲劳监测法测试是一项省时省力、简单易行、安全可靠的生理指标监测方法,具有精准度高、相对成本低、即刻知晓结果的优势.
Abstract
This paper aims to explore the effectiveness of three methods for monitoring exercise fatigue,name-ly,lower limb explosive force reduction rate(decrease score/pre-training score),weight loss rate(loss weight/pre-training weight),and training fatigue accumulation score(subjective fatigue scale post-training score-pre-training score).With 15 players from the Chinese National Men's Blind Football Team as experimental subjects(4 international players,10 national players,1 nonrated player,aged 25.6±5.28 years,height 1.762± 0.049m,weight 70.93±7.61kg,BMI 22.95±1.81,training duration 8.8±3.54 years),data on players'lower limb explosive force reduction rate,weight loss rate,and training fatigue accumulation score were obtained through experimental tests.Correlation analysis was conducted on these indicators and their own serum testoster-one/cortisol(T/C).The results show there is an approximately linear negative correlation between the lower limb explosive force reduction rate and the T/C of players(| R |=|-0.981 |>0.70);and a very high nega-tive correlation between weight loss rate and T/C(| R |=|-0.924 |>0.70);and a very high negative corre-lation between training fatigue accumulation score and T/C(| R |=|-0.718 |>0.70).It is concluded that the accuracy of the lower limb explosive force reduction rate monitoring method is higher than that of the weight loss rate and training fatigue accumulation score monitoring methods,and the efficiency of the weight loss rate monitoring method is better than that of the training fatigue accumulation score monitoring method;for blind play-ers,the lower limb explosive force reduction rate exercise fatigue monitoring method is a time-saving,labor-sav-ing,simple,safe and reliable physiological indicator monitoring method,which has the advantages of high accu-racy,relatively low cost and immediate knowledge of the results.
