To investigate the effects of heavy strength training on the mean power output in a 5-min all-out trial following 185 min of submaximal cycling at 44% of maximal aerobic power output in well-trained cyclists. Twenty well-trained cyclists were assigned to either usual endurance training combined with heavy strength training [E+S; n=11 (♂=11)] or to usual endurance training only [E; n=9 (♂=7, ♀=2)]. The strength training performed by E+S consisted of four lower body exercises [3 × 4-10 repetition maximum (RM)], which were performed twice a week for 12 weeks. E+S increased 1 RM in half-squat (P≤0.001), while no change occurred in E. E+S led to greater reductions than E in oxygen consumption, heart rate, blood lactate concentration, and rate of perceived exertion (P<0.05) during the last hour of the prolonged cycling. Further, E+S increased the mean power output during the 5-min all-out trial (from 371 ± 9 to 400 ± 13 W, P<0.05), while no change occurred in E. In conclusion, adding strength training to usual endurance training improves leg strength and 5-min all-out performance following 185 min of cycling in well-trained cyclists.
研究目的在于探讨在经过 185 分钟、最大有氧输出功率的 44%强度的亚极量自行车骑行后，大强度力量训练对 5 分钟全力骑行试验平均功率输出的影响。20 名训练有素的自行车运动员被分配到常规耐力训练结合大强度力量训练组[E+S；n=11（♂=11）]或仅常规耐力训练组[E；n=9（♂=7，♀=2）]。E+S 组进行的力量训练包括四项下肢运动[3×4-10 重复最大重量（RM）]，每周进行两次，共进行 12 周。E+S 组半蹲 1RM 显著增加（P≤0.001），而 E 组没有变化。与 E 组相比，E+S 组在长时间自行车骑行的最后 1 小时内，耗氧量、心率、血乳酸浓度和主观用力程度（RPE）均显著降低（P<0.05）。此外，E+S 组在 5 分钟全力骑行试验中的平均功率输出增加（从 371±9 增加到 400±13 W，P<0.05），而 E 组没有变化。总之，在经过 185 分钟的自行车骑行后，在常规耐力训练中加入力量训练可以提高运动员腿部力量和 5 分钟全力骑行的表现。
