摘要

背景:身体活跃的人总体上骨转换加速。然而,人们对不同类型的阻力训练对青少年举重运动员骨代谢指标的影响知之甚少。目的:研究青少年高水平举重运动员肩袖肌等速训练与等速训练及停止训练一个月对血骨代谢指标的影响。方法:将16名马来西亚青少年男子举重运动员(年龄14.88±1.31岁)按体重配对,随机分为两组:等速训练组(FIT,n=7)和等渗训练组(TON,n=9)。该实验在训练周期的准备阶段进行,共24次,每周3次,使用测力计或哑铃进行8周。在训练开始前、训练后和训练停止后一个月采集血样,并分析血清骨钙素、血清1型胶原C-末端肽(CTX-1)和血清总钙的血液代谢标志物。结果:总钙浓度在任何时间组之间都没有差异,这表明时间的主要影响不显著(F=1.89,p=.166),没有条件-时间交互作用(F=0.64,p=.533)。血清骨钙素浓度在任何时候组之间都无差异,如时间的主要效应不显著(F=2.10,p=.162)和无条件-时间相互作用效应(F=0.024,p=.912)所示。各组间血清CTX-1浓度在任何时候都没有差异,如时间的非显著主效应(F=3.12,p=0.59)和无条件-时间交互作用(F=1.59,p=.221)所示。结论:在高水平青少年举重运动员中,经过8周的等速或等渗附加训练后,血清总钙、骨钙素和CTX-1没有观察到显著变化。

Changes of bone metabolism markers following additional isokinetic and isotonic training and its subsequent cessation in advanced level adolescent weightlifters
Background: Physically active people present overall accelerated bone turnover. However, less is known about the effects of different types of resistance training on bone metabolism markers among adolescent weightlifters. Objective: The purpose of this study was to investigate the effects of isokinetic training versus isotonic training of rotator cuff muscles and one month of cessation of training on blood bone metabolism markers among adolescent advanced level weightlifters. Methods: Sixteen adolescent male weightlifters (age 14.88 ± 1.31 years) who represented their state in Malaysia were weight-matched and randomly assigned into two training groups: isokinetic training (FIT, n = 7) and isotonic training (TON, n = 9) groups. The experiment was conducted during the preparatory phase of the training cycle for a total of 24 sessions with three sessions per week for eight weeks using dynamometer or dumbbells. Blood samples were collected before the commencement of training, after training and one month following the cessation of training and analyzed for determining blood metabolism markers of serum osteocalcin, serum C-telopeptide of type 1 collagen (CTX-1), and serum total calcium. Results: Total calcium concentrations were not different between groups at any time, as indicated by a non-significant main effect of time (F = 1.89, p = .166) and no condition × time interaction effect (F = 0.64, p = .533). Serum osteocalcin concentrations were not different between groups at any time, as indicated by a non-significant main effect of time (F = 2.10, p = .162) and no condition × time interaction effect (F = 0.024, p = .912). Serum CTX-1 concentrations were not different between groups at any time, as indicated by a non-significant main effect of time (F = 3.12, p = .059) and no condition × time interaction effect (F = 1.59, p = .221). Conclusions: No significant changes were observed in serum total calcium, osteocalcin and CTX-1 following either eight weeks of isokinetic or isotonic additional training among advanced level of adolescent weightlifters.
