【摘要】：目的:研究小麦肽预防散打运动员发生过度训练的干预效果。方法:将扬州大学33名高水平散打运动员随机分为对照组、小麦肽低剂量组(3g)、中剂量组(6g)和高剂量组(9g),于每次大负荷散打训练后分别补充安慰剂和低、中和高剂量小麦肽,实验前后分别测定各组体重、握力、腿部肌力、反应时以及血清肌酸激酶(CK)活性、睾酮(T)和皮质醇(C)含量。结果:(1)6周大负荷散打专项训练后,对照组体重、握力均显著下降,反应时显著延长,血清CK活性显著上升,T含量显著降低,C含量虽有升高,但无统计学意义。(2)在大负荷散打训练后补充不同剂量的小麦肽在一定程度上能减轻体重的降低和血清CK活性的升高;与训练前相比,小麦肽低剂量组除了腿部肌力显著增加和血清C显著降低外,其它指标均无显著性变化;中剂量组握力、腿部肌力和血清T含量显著增加,反应时和血清C含量显著降低;高剂量组除握力和腿部肌力显著增加外,其它指标均无显著性变化。从训练前后各指标的变化量来看,与对照组相比,低剂量组握力、腿部肌力显著增加,血清C含量显著降低,血清CK活性增加的幅度显著减小;中剂量组的体重、握力、腿部肌力、血清T含量均显著增加,反应时、血清CK活性、C含量均显著降低;高剂量组除握力、腿部肌力显著增加、反应时显著降低外,其它指标均无显著性差异。结论:6周的大负荷运动训练使散打运动员产生过度训练,而在大负荷散打训练时补充不同剂量的小麦肽均可有效减轻肌肉损伤,加速运动性疲劳的恢复,对防止过度训练的发生具有一定作用,其中以补充中剂量(6g)小麦肽的效果最好。
[Abstract]:Objective: to study the effect of wheat peptide on preventing Sanda athletes from overtraining. Methods: 33 high level Sanda athletes from Yangzhou University were randomly divided into three groups: control group, low dose group (3G), middle dose group (6 g) and high dose group (9 g). Body weight, grip strength, leg muscle strength, reaction time, serum creatine kinase (CK) activity, testosterone (T) and cortisol (C) contents were measured before and after the experiment. Results: (1) after 6 weeks of intensive Sanda special training, the weight and grip strength of the control group were significantly decreased, the reaction time was significantly prolonged, and the serum CK activity was significantly increased. But there was no statistical significance. (2) supplementation of different doses of wheat peptide after heavy load Sanda training could reduce the weight loss and increase the activity of serum CK to a certain extent, compared with that before training. There was no significant change in other indexes except leg muscle strength and serum C decrease in low dose group, grip strength, leg muscle strength and serum T content in middle dose group were significantly increased, reaction time and serum C content were significantly decreased. There was no significant change in other indexes except grip strength and leg muscle strength in high dose group. Compared with the control group, the grip strength, leg muscle strength, serum C content and CK activity of the low dose group increased significantly, and the weight and grip strength of the middle dose group decreased significantly. Leg muscle strength and serum T content were significantly increased, serum CK activity and C content were significantly decreased in the reaction group, except grip strength, leg muscle strength and reaction time, there was no significant difference in other indexes in the high dose group. Conclusion the overtraining of Sanda athletes after 6 weeks of heavy load exercise training can effectively reduce muscle injury and accelerate the recovery of exercise fatigue by adding different doses of wheat peptide in heavy load Sanda training. It has a certain effect on preventing overtraining, and the best effect is to supplement the middle dose (6 g) wheat peptide.
