Elite cyclists have often a limited period of time available during their short preparation phase to focus on development of maximal strength; therefore, the purpose of the present study was to investigate the effect of 10-week heavy strength training on lean lower-body mass, leg strength, determinants of cycling performance and cycling performance in elite cyclists. Twelve cyclists performed heavy strength training and normal endurance training (E&S) while 8 other cyclists performed normal endurance training only (E). Following the intervention period E&S had a larger increase in maximal isometric half squat, mean power output during a 30-s Wingate sprint (P < 0.05) and a tendency towards larger improvement in power output at 4 mmol ∙ L [la] than E (P = 0.068). There were no significant difference between E&S and E in changes in 40-min all-out trial (4 ± 6% vs. -1 ± 6%, respectively, P = 0.13). These beneficial effects may encourage elite cyclists to perform heavy strength training and the short period of only 10 weeks should make it executable even in the compressed training and competition schedule of elite cyclists.
精英自行车运动员在其短暂的准备阶段通常只有有限的时间来专注于最大力量的发展;因此,本研究的目的是调查为期10周的高强度力量训练对精英自行车运动员的下肢瘦体重、腿部力量、骑行表现的决定因素以及骑行表现的影响。12名自行车运动员进行高强度力量训练和常规耐力训练(E&S),而另外8名自行车运动员仅进行常规耐力训练(E)。在干预期后,E&S组在最大等长半蹲、30秒温盖特冲刺期间的平均功率输出方面有更大的增加(P<0.05),并且在4毫摩尔∙升[乳酸]时功率输出的改善趋势比E组更大(P = 0.068)。在40分钟全力试验的变化方面,E&S组和E组之间没有显著差异(分别为4±6%和-1±6%,P = 0.13)。这些有益效果可能会鼓励精英自行车运动员进行高强度力量训练,而仅10周的短时间应该使其即使在精英自行车运动员紧凑的训练和比赛日程中也是可执行的。
