背景与目的振动训练是一种较新的运动干预方法。本研究探讨了振动锻炼对力量（力生产能力）和权力的影响，在老年人who are health.Participants和MethodsThirty参与者（平均年龄=73.7岁，SD=4.6）被随机分配到振动运动训练（VIB）组或运动无振动训练（EX）组。干预措施包括每周3次，持续8周。结果的措施包括等速屈肌和伸肌的力量和权力的髋关节，膝关节，和ankle.ResultsThe VIB组显着改善踝跖屈肌的力量和权力相比，EX组。然而，有没有显着差异之间的VIB和EX组的膝关节屈肌或伸肌strength.Discussion and ConclusionVibration训练有助于增加跖屈肌的力量和权力。然而，VIB组和EX组的膝关节和髋关节屈肌和伸肌的力量增益相当。未来的振动协议应该探索不同的身体位置，以瞄准腿部更高的肌肉。
Background and PurposeVibration training is a relatively new exercise intervention. This study investigated the effects of vibration exercise on strength (force-producing capacity) and power in older adults who are healthy.Participants and MethodsThirty participants (mean age=73.7 years, SD=4.6) were randomly assigned to a vibration exercise training (VIB) group or an exercise without vibration training (EX) group. The interventions consisted of 3 sessions per week for 8 weeks. Outcome measures included isokinetic flexor and extensor strength and power of the hip, knee, and ankle.ResultsThe VIB group significantly improved ankle plantar flexor strength and power compared with the EX group. However, there were no significant differences between the VIB and EX groups for knee flexor or extensor strength.Discussion and ConclusionVibration training contributed to an increase in plantar flexor strength and power. However, the strength gains for the knee and hip flexors and extensors for the VIB group and the EX group were comparable. Future vibration protocols should explore different body positions to target muscles higher up on the leg.
