目的本研究调查了慢速运动方案是否可以应用于使用体重的阻力训练。此外，干预方案将增强式运动与抗阻运动相结合，以改善整体身体机能。方法共有39名活跃的老年人参加了为期16周的干预。该计划包括五项阻力练习和四项使用自身体重的增强式练习，每项练习为一组。参与者被分配到两个实验组之一。一组进行缓慢运动和产生强直力的阻力练习（3 秒同心、3 秒偏心和 1 秒等长动作，每次重复之间不休息）。另一组作为运动比较，遵循相同的方案，但速度正常（1 秒偏心和 1 秒向心动作，每次重复之间休息 1 秒）。干预前后测量肌肉大小、力量和身体功能。结果干预后，两组上肢、下肢力量、最大腿部伸肌力均显着提高。两组的肌肉大小都没有变化。各组间各项参数均无显着差异。结论仅使用自身体重的慢速抗阻运动和增强式运动的干预方案可以改善老年人的身体功能，即使每次运动仅做一组。但并没有增强肌肉肥大的效果。需要进一步尝试，例如增加多组训练，以诱导肌肉肥大。Geriatr Gerontol Int 2015； 15：1270–1277。
AimThe present study investigated whether a slow movement protocol can be applied to resistance training using bodyweight. In addition, the intervention program combined plyometric exercise with resistance exercise to improve physical function overall.MethodsA total of 39 active elderly adults participated in a 16‐week intervention. The program consisted of five resistance exercises and four plyometric exercises using their own bodyweight with a single set for each exercise. Participants were assigned to one of two experimental groups. One group carried out resistance exercise with slow movement and tonic force generation (3‐s concentric, 3‐s eccentric and 1‐s isometric actions with no rest between each repetition). The other group as a movement comparison followed the same regimen, but at normal speed (1‐s eccentric and 1‐s concentric actions with 1‐s rest between each repetition). Muscle size, strength and physical function were measured before and after the intervention period.ResultsAfter the intervention, strengths of upper and lower limbs, and maximum leg extensor power were significantly improved in both groups. Muscle size did not change in either group. There were no significant differences in any of the parameters between groups.ConclusionsThe intervention program using only own bodyweight that comprised resistance exercise with slow movement and plyometric exercise can improve physical function in the elderly, even with single sets for each exercise. However, there was no enhanced muscle hypertrophic effect. Further attempts, such as increasing performing multiple sets, would be required to induce muscle hypertrophy.Geriatr Gerontol Int 2015; 15: 1270–1277.
