基于心率变异性监测中医刮痧抗运动性疲劳的效果

Effects to Resist Sport Fatigue Based on the Testing of the Heart Rate Variability with the Gua Sha Therapy of Traditional Chinese Medicine

目的通过测量国家男子举重队运动员的心率变异性(HRV),判断其正常训练后的疲劳状态,探索中医刮痧疗法在竞技体育领域的应用价值。方法筛选出26名冬训期间(试验期间)处于运动性疲劳状态的国家男子举重队运动员,分为刮痧组和对照组(每组13人)。刮痧组除接受竞技举重训练外,另接受12周(每周2次,共24次)的中医刮痧干预治疗,对照组仅接受竞技举重训练。组内比较采用配对样本t检验、组间比较采用独立样本t检验,对竞技举重训练中的成绩、心率变异性时域和频域主要指标、匹兹堡睡眠质量指数(PSQI)进行监测与分析。结果刮痧组竞技训练抓举和挺举成绩增加值[(5.37±0.80)kg和(5.87±1.04)kg]显著高于对照组[(1.00±0.31)kg和(1.46±0.42)kg](P<0.05)。刮痧组心率变异性的时域指标(P<0.05)、频域指标[低频(P<0.05)、低频与高频比值(P<0.01)]的保持效果、PSQI(P<0.01)显著优于对照组,且PSQI变化值与时域指标相邻RR间期差值的均方根变化值呈负相关(r=-0.781,P<0.05)。结论在竞技举重训练导致的运动性疲劳恢复中合理进行中医刮痧干预治疗,能提升运动员的恢复效果,体现为自主神经调节中副交感神经活动明显增强;中医刮痧干预还可提高运动员的睡眠质量,从而提升抗运动性疲劳效果。

Objective By measuring the heart rate variability(HRV)of the national men*s weightlifting team athletes,to judge their fatigue state after normal training,and to explore the application value of Gua Sha therapy of traditional Chinese medicine in the field of competitive sports.Methods 26 athletes of national men's weightlifting team were selected and divided into Gua Sha group and control group(13 in each group).In addition to competitive weightlifting training,the Gua Sha group received Gua Sha therapy for 12 weeks(twice a week,24 times in total),while the control group only received competitive weightlifting training.Paired sample t-test was used for intra group comparison,and independent sample t-test was used for inter group comparison.The performance of competitive weightlifting training,heart rate variability in time domain and frequency domain,and Pittsburgh sleep quality index(PSQI)were monitored and analyzed.Results The increased scores of snatch and clean and jerk in Gua Sha Group[(5.37±0.80)kg and(5.87±1.04)kg]were significantly more than those in control group[(1.00±0.31)kg and(1.46±0.42)kg](P<0.05).The time domain index(P<0.05),frequency domain index[low frequency(P<0.05),low frequency to high frequency ratio(P<0.01)]and PSQI(P<0.01)of the Gua Sha group were significantly better than those of the control group,and the change of PSQI was negatively correlated with the root mean square of the sum of the squares of the difference in the time domain intermediate period(r=-0.781,P<0.05).Conclusion In the recovery of sports fatigue caused by competitive weightlifting training,reasonable Gua Sha therapy of traditional Chinese medicine can improve the recovery effect of athletes,which is embodied in the obvious enhancement of parasympathetic nerves activity in autonomic nervous regulation;Gua Sha therapy can also improve the sleep quality of athletes,so as to enhance the effect of anti-sport fatigue.
