Muscle power has been reported to be critical in counteracting age-related declines in functional performance. Muscle power output in functional performance exercises can be greatly improved in a short period of time (i.e., ≤ 12 weeks) using specific exercise interventions such as power training (i.e., exercises attempting to move loads ranging from 20 to 70% of 1-repetition maximum as fast as possible during the concentric muscle action, followed by a controlled, slower eccentric muscle action). Despite the widespread evidence on the effectiveness of power training in older adults (~ 300 scientific articles published on this topic in the past 10 years), some scientists do not recommend the use of explosive-type muscular contractions during resistance training (i.e., power training) for the older population; indeed, some international guidelines do not mention this type of exercise for older people. The reasons underlying this absence of mention and recommendation for the use of power training as a fundamental exercise strategy for older people are still not well known. Therefore, we attempted to point out the main issues about safety, feasibility, and effectiveness of muscle power training to promote neuromuscular functional improvements in older people.

据报道，肌肉力量对于抵消与年龄相关的功能表现下降至关重要。使用特定的运动干预措施，例如力量训练（即尝试移动 20% 到 70% 的负荷，重复 1 次的运动），可以在短时间内（即 ≤ 12 周）大大提高功能性运动中的肌肉力量输出在向心肌肉动作期间尽可能快地达到最大，然后是受控的、较慢的离心肌肉动作）。尽管有广泛的证据表明力量训练对老年人的有效性（过去 10 年发表了约 300 篇关于该主题的科学文章），但一些科学家不建议在阻力训练（即力量训练）期间使用爆发式肌肉收缩) 对于老年人口；的确，一些国际指南没有提到老年人的这种锻炼。没有提及和推荐使用爆发力训练作为老年人的基本锻炼策略的原因尚不清楚。因此，我们试图指出肌肉力量训练促进老年人神经肌肉功能改善的安全性、可行性和有效性的主要问题。
