Slow walking speed as one indicator of physical frailty has been found to be associated with deterioration of the health status. Although many reports have shown that exercise training improves motor function, it is unclear whether a group-based and short-term health promotion intervention will improve motor function in older adults.
This study aimed to examine the effectiveness of a short-term health promotion intervention on motor function in community-dwelling older adults.
A 6-month middle-term and moderate-intensity programme (MTMIP) and a 6-week short-term high-intensity programme (STHIP) were conducted. There were 28 and 29 subjects selected for the MTMIP and STHIP, respectively. The difference in motor function test outcomes was compared by assessment of comfortable walking speed, maximal walking speed, a sit-to-stand test (STS), and a timed up-and-go test (TUG).
Comfortable walking speed, maximum walking speed, STS and TUG were significantly improved at end of the programme in the STHIP group (p = 0.02, p = 0.03, p < 0.001 and p = 0.002). Multiple regression analysis revealed that implementation of STHIP had a significant effect on end-of-programme comfortable walking speed (β = 0.19, p = 0.006, 95% CI 0.06 to 0.32).
It was assumed that the training content of the STHIP, with its emphasis on high intensity and physical performance, was the main factor in improved walking speed.
Our results demonstrated the effectiveness of STHIP on motor function. These findings could help support development of more effective intervention methods in community-dwelling older adults.
作为身体虚弱的一个指标，缓慢的步行速度与健康状况的恶化有关。虽然许多报告表明运动训练可以改善运动功能，但目前尚不清楚基于群体的短期健康促进干预是否会改善老年人的运动功能。
本研究旨在探讨短期健康促进干预对社区居住老年人运动功能的影响。
进行了 6 个月的中期和中等强度方案（MTMIP）和 6 周的短期高强度方案（STHIP）。分别有 28 名和 29 名受试者入选 MTMIP 和 STHIP。通过评估舒适步行速度、最大步行速度、坐站测试（STS）和计时起身行走测试（TUG）来比较运动功能测试结果的差异。
在 STHIP 组，方案结束时舒适步行速度、最大步行速度、STS 和 TUG 均显著提高（p=0.02，p=0.03，p<0.001 和 p=0.002）。多元回归分析显示，实施 STHIP 对方案结束时的舒适步行速度有显著影响（β=0.19，p=0.006，95%CI 0.06 至 0.32）。
假设 STHIP 的训练内容强调高强度和身体表现，这是提高步行速度的主要因素。
我们的结果表明 STHIP 对运动功能有效。这些发现可以帮助支持为社区居住的老年人制定更有效的干预方法。
