【摘要】：目的:观察不同类型的力量训练对运动员机体内单胺类神经递质代谢物的作用,并探讨其机制,从而在无创性尿液神经递质代谢指标方面为运动训练监控提供部分科学理论依据。方法:选择北京市参加全运会的一线男子游泳运动员6名进行3个阶段(最大力量期、专项力量期和爆发力量期)的力量训练。取力量训练周期前、3个阶段力量训练期内第1次训练课后以及3个阶段力量训练期结束后24小时全尿,测量其尿肌酐及单胺类神经递质代谢物水平。结果:一次性力量训练课后的24h尿体积均显著降低(P0.05),而尿肌酐水平均无变化;与训练前的安静值相比,3种力量训练的一次性力量训练后尿液中香草扁桃酸(VMA)与高香草酸(HVA)均有不同程度的升高,其中最大力量训练期提高水平最多,专项力量期次之,爆发力量期最低;而一次性力量训练后尿液中的5-羟吲哚乙酸(5-HIAA)均未有显著变化;长期力量训练后受试者安静态24小时的尿体积和尿肌酐水平均无显著变化。与训练前安静值相比,长期力量训练后安静态24小时尿VMA、HVA、5-HIAA的水平均无显著变化。结论:一次性力量训练可促进尿液VMA和HVA浓度升高,提示机体儿茶酚胺(CA)的代谢水平增强,并且训练强度越大促进的效果越明显;一次性力量训练对5-HIAA代谢没有影响,提示机体5-HT的代谢水平未受影响;而长期的力量训练对尿液中单胺类神经递质代谢物的水平没有影响。
[Abstract]:Objective: to observe the effects of different types of strength training on monoamine neurotransmitter metabolites in athletes and to explore its mechanism. In order to provide some scientific theoretical basis for monitoring sports training in non-invasive urine neurotransmitter metabolism index. Methods: six first-line male swimmers who participated in the National Games in Beijing were selected for three stages (maximum strength period). Before the strength training cycle, after the first training session in the three stages of strength training period and 24 hours after the end of the three stages strength training period, The levels of urinary creatinine and monoamine neurotransmitter metabolites were measured. Results: the urine volume decreased significantly in 24 hours after one time strength training, but the level of urinary creatinine did not change. Compared with the rest value before training, the urine VMAs and HVA in urine of the three strength training groups were increased in varying degrees, among which the maximum strength training period was the highest, and the special strength period was the second. The burst strength period was the lowest, but 5-HIAA in urine did not change significantly after one-off strength training. There was no significant change in urine volume and creatinine level after long-term strength training. There was no significant change in the level of 5-HIAA in urine after long-term strength training. Conclusion: the concentration of VMA and HVA in urine can be increased by one-off strength training, suggesting that the metabolic level of catecholamine can be enhanced. The greater the training intensity was, the more obvious the effect was, and the one-time strength training had no effect on the metabolism of 5-HIAA, suggesting that the metabolic level of 5-HT was not affected. Long-term strength training had no effect on the level of monoamine neurotransmitter metabolites in urine.
