一些研究表明，当阻力训练持续到个人无法进行额外重复（即重复失败）的程度时，力量的改善会更大。在重复失败点后进行额外的强制重复，从而进一步增加设定量是常见的阻力训练实践。然而，短期使用这种练习是否会增加阻力训练的力量发展程度尚不清楚，本文进行了研究。 12 名篮球运动员和 10 名排球运动员每周训练 3 次，持续 6 周，每次训练完成 4 X 6、8 X 3 或 12 X 3（组数 X 重复）卧推。与 8 X 3 组相比，4 X 6 方案涉及更长的工作间隔，而 12 X 3 方案涉及更高的训练量，因此每组都经过专门设计，以在每次训练中引发不同数量的强制重复。对受试者进行 3 次和 6 次重复最大 (RM) 卧推（分别为 81.5 ± 9.8 和 75.9 ± 9.0 kg，平均值 ± SD）和 40 公斤史密斯机卧推投掷功率（589 ± 100 W）进行测试。 4 X 6 和 12 X 3 组每次训练的强迫重复次数 (p > 0.01) 比 8 X 3 组多（分别为 4.1 ± 2.6、3.1 ± 3.5 和 1.2 ± 1.8 次重复），而 12 X 3 组的工作量增加了约 40%，同心时间增加了 30%。正如预期的那样，所有组均提高了 3RM（4.5 kg，95% 置信限，3.1-6.0）、6RM（4.7 kg，3.1-6.3）、卧推峰值功率（57 W，22-92）和平均功率（23 W，4-42）（所有 p ≤ 0.02）。各组之间的力量或功率增益没有显着差异。总之，当达到重复力竭时，额外的强迫重复或额外的设定量都不会进一步提高力量增益的幅度。这一发现对具有中等力量训练经验的年轻运动员通过强制重复增加额外训练量的效果提出了质疑。
Some research suggests that strength improvements are greater when resistance training continues to the point at which the individual cannot perform additional repetitions (i.e., repetition failure). Performing additional forced repetitions after the point of repetition failure and thus further increasing the set volume is a common resistance training practice. However, whether short-term use of this practice increases the magnitude of strength development with resistance training is unknown and was investigated here. Twelve basketball and 10 volleyball players trained 3 sessions per week for 6 weeks, completing either 4 X 6, 8 X 3, or 12 X 3 (sets X repetitions) of bench press per training session. Compared with the 8 X 3 group, the 4 X 6 protocol involved a longer work interval and the 12 X 3 protocol involved higher training volume, so each group was purposefully designed to elicit a different number of forced repetitions per training session. Subjects were tested on 3- and 6-repetition maximum (RM) bench press (81.5 ± 9.8 and 75.9 ± 9.0 kg, respectively, mean ± SD), and 40-kg Smith Machine bench press throw power (589 ± 100 W). The 4 X 6 and 12 X 3 groups had more forced repetitions per session (p > 0.01) than did the 8 X 3 group (4.1 ± 2.6, 3.1 ± 3.5, and 1.2 ± 1.8 repetitions, respectively), whereas the 12 X 3 group performed approximately 40% greater work and had 30% greater concentric time. As expected, all groups improved 3RM (4.5 kg, 95% confidence limits, 3.1–6.0), 6RM (4.7 kg, 3.1–6.3), bench press throw peak power (57 W, 22–92), and mean power (23 W, 4–42) (all p ≤ 0.02). There were no significant differences in strength or power gains between groups. In conclusion, when repetition failure was reached, neither additional forced repetitions nor additional set volume further improved the magnitude of strength gains. This finding questions the efficacy of adding additional volume by use of forced repetitions in young athletes with moderate strength training experience.
