摘要
目的:探讨单次、多次加压训练与传统增肌训练,对优秀男子手球运动员与肌肉合成、分解相关的部分激素和生物活性因子的影响。方法:将18名优秀男子手球运动员按照年龄随机分为实验组和对照组。实验组在加压(下肢加压,加压带宽度5cm,压力值:着装压45mmHg,训练压200mmHg)下完成每周3次的深蹲、硬拉、负重剪蹲和推雪橇车前行练习,对照组按照传统的训练方式训练。分别在首次训练前晨起(PRE)、训练后即刻(POST-0)、训练后次日晨(POST-1d)和连续训练两周后晨起(POST-14d)采集血液样本,检测睾酮、皮质醇、胰岛素、HGH、MSTN及IGF-1、IL-6、NOS等指标,进行组间和组内的对比分析。结果:1)HGH:与PRE相比(下同),实验组和对照组在POST-0分别上升962.2%(P<0.01)和568.2%(P<0.01),组间比较P<0.05;在POST-1d分别上升14.3%和0.3%;在POST-14d分别升高16.6%和8.7%。2)IGF-1:实验组和对照组在POST-0分别升高2.6%(P<0.05)和下降3.8%,在POST-1d分别下降2.7%和1.2%;在POST-14d分别下降1.6%和7.2%(P<0.01)。3)NOS:实验组在POST-0上升5.8%、POST-1d下降3.7%(P<0.01),而对照组为持续下降1.3%和7.4%,在POST-0,组间比较P<0.05;在POST-14d实验组和对照组分别下降11.8%(P<0.01)和16.3%(P<0.01)。4)睾酮:实验组和对照组在POST-0分别下降30.9%和35.3%;在POST-1d分别下降7.3%和9.7%;在POST-14d分别下降1.3%和5.6%,组间比较P<0.05。结论:对于竞技水平较高的运动员来说,与传统增肌训练相比,加压训练能更加有效地促进与肌肉合成相关的NOS、HGH等激素和生物活性因子的良性变化,且由于负荷相对较小,加压训练更有利于竞技状态的保持。加压训练值得在高水平运动队中推广和应用。为达到更好的训练效果,进行加压训练同样需要随着机体的适应而调整个体的训练压力和训练负荷。
Objective:To investigate the effects of single and multiple KAATSU training on some hormones and bioactive factors related to muscle synthesis composition of elite male handball players compared with traditional muscle hypertrophy training.Methods:18 excellent male handball players were randomly divided into experimental group and control group according to their age.The experimental group completed squats,hard pull,weight shear squats and pushing sleigh cart forward exercises three times per week under pressure(lower limb pressure,pressure band width of 5 cm,pressure value:dressing pressure of 45 mmHg,under the inflatable pressure 200 mmHg).The control group was trained according to the traditional training method.Blood samples,testosterone,cortisol,insulin,growth hormone,myostatin,iris and insulin-like growth factor,interleukin-6,NO synthetase were detected in the morning of the first training(PRE),immediately after training(POST-0),next morning after training(POST-1d),and the morning after 2 weeks training(POST-14d),respectively.Comparative analysis between and within groups was performed.Results:1)Human growth hormone(HGH):Compared with PRE(same as below),experimental and control groups in creased by 962.2%(P<0.01)and 568.2%(P<0.01)at POST-0,comparison between groups P<0.05;at POST-1d,increased by 14.3%and 0.3%;at POST-14d increased by 16.6%and 8.7%.2)Insulin-like growth factor-1(IGF-1):Experimental group decreased by 2.6%(P<0.05)at POST-0,and by 2.7%at POST-1d,and Control group decreased by 3.8%and 1.2%.POST-14d experimental group decreased by 1.6%,and control group decreased by 7.2%(P<0.01).3)NO synthase(NOS):Experimental group increased by 5.8%at POST-0,and decreased by 3.7%at POST-1d(P<0.01).Control group continued to decrease by 1.3%and 7.4%,compared with group at POST-0 P<0.05.At the time point of POST-14d,experimental and control group decreased by 11.8%(P<0.01)and 16.3%(P<0.01).4)Testosterone(T):compared with PRE(Same as below),experimental and control group decreased by 30.9%and 35.3%at POST-0,by 7.3
