This study aimed to assess the effects of flywheel resistance exercise training on postural stability and mobility in older adults and to investigate whether changes in power are related to improvements in balance. Thirty-six participants were randomly allocated to either a flywheel resistance exercise training group (ETG; n = 18) who underwent 6-weeks of training (2 to 3 days per week) or a control group (CON; n = 18). The average power and Mean Propulsive Velocity (MPV) were computed. Timed up-and-go test (TUG) and postural balance (anterior-posterior (AP) and medial-lateral (ML) center of pressure (COP) excursions) in different tasks were also assessed. Within-group analyses showed a significantly better performance in mobility (TUG, p < 0.01) and COP with open eyes (p < 0.05) for ETG. Between-groups analyses showed significant improvements in TUG (-0.68 [-1.25 to -0.98]) and in COP (-2.90 [-4.82 to -0.99]) in ETG compared with CON. Mean power also increased in ETG and the changes were related to those observed in stability (COP; r = -0.378, p < 0.05). In conclusion flywheel resistance exercise training improved balance and mobility in older adults as well as muscle power.
本研究旨在评估飞轮抗阻训练对老年人姿势稳定性和移动能力的影响，并探讨力量的变化是否与平衡的改善有关。36 名参与者被随机分配到飞轮抗阻训练组（ETG；n=18）和对照组（CON；n=18）。计算平均功率和平均推进速度（MPV）。还评估了不同任务中的计时起立行走测试（TUG）和姿势平衡（睁眼时前后向（AP）和内外侧向（ML）的中心压力（COP）偏移）。组内分析显示，ETG 在移动性（TUG，p<0.01）和睁眼时 COP（p<0.05）方面的表现明显更好。组间分析显示，与 CON 相比，ETG 在 TUG（-0.68[-1.25 至-0.98]）和 COP（-2.90[-4.82 至-0.99]）方面有显著改善。ETG 的平均功率也增加了，并且这些变化与稳定性（COP；r=-0.378，p<0.05）的变化有关。总之，飞轮抗阻训练改善了老年人的平衡和移动能力以及肌肉力量。
