经皮穴位电刺激对足球高水平大学生BUN、血清T、血清CK-MM的影响

摘要

Objective:To observe the impact of the transcutaneous electrical acupoint stimulation (TEAS) on blood urea nitrogen (BUN), serum testosterone (T) and serum creatine kinase isoenzyme-MM (CK-MM) of college athletes in high-level football match.Methods:Twenty-four college football players were randomly divided into control group, Group 1 and Group 2, with eight athletes in each group. The athletes in Group 1 and Group 2 were interfered by TEAS during the training, before and after the match. In the meanwhile, BUN, T, and CK-MM concentrations were tested at different stages. Results:There was no statistically difference of BUN, T, and CK-MM during training (P＞0.05). However, BUN and CK-MM concentrations of the athletes in Group 1 and Group 2 during the stages of assembling training, match, and recovery were lower than those of the control group (P＜0.05 or P＜0.01), along with delayed decrease of T concentration (P＜0.05 or P＜0.01). Conclusion:The TEAS interference can effectively relieve the exercise-induced fatigue result from the load training with adaptive enhancement. But it makes no effect on the long time light-load training and heavy-load training. The TEAS interference has a better recovery in training fatigue during the training stage and after the match.%目的:观察经皮穴位电刺激法(TEAS)对足球高水平大学生比赛中血尿素氮(BUN)、血清睾酮(T)、血清肌酸激酶同工酶-MM(CK-MM)的影响.方法:将24名足球高水平大学生按照随机数字表法分对照组、治疗1组和治疗2组,每组8名.治疗1组和治疗2组分别在训练期和比赛前后进行TEAS干预,并在比赛周期的不同阶段检测BUN、血清T、血清CK-MM含量.结果:在正常训练期及干预训练期,3组BUN、血清T、血清CK-MM含量比较差异无统计学意义(P＞0.05);而在集训期-比赛期-训练恢复期,治疗1组和治疗2组中BUN、血清CK-MM含量与对照组比较均降低(P＜0.05,P＜0.01),并延缓血清T含量的下降(P＜0.05,P＜0.01).结论:TEAS干预能有效延缓适应性增强负荷运动训练时所产生的运动性疲劳,但对长时间轻负荷运动训练、大负荷运动训练效果不显著;在训练或比赛后进行TEAS干预对运动性疲劳恢复更加有效.
