背景该研究测试了力量和耐力训练对老年人步态、平衡、身体健康状况、跌倒风险和健康服务使用的影响。本研究为单盲、随机对照试验，采用意向治疗分析。成年人（n = 105），年龄68-85岁，至少有轻度缺陷的力量和平衡，从一个健康维护组织的随机样本登记。干预是监督运动（1小时的会议，每周三次，持续24-26周），然后是自我监督运动。运动组包括使用重量机器的力量训练（n = 25）。使用自行车的耐力训练（n = 25），以及力量和耐力训练（n = 25）。研究结果包括步态测试、平衡测试、身体健康状况测量、自我报告的福尔斯（长达25个月的随访）。以及住院和门诊的使用和费用。运动对步态、平衡或身体健康状况没有影响。运动对跌倒风险具有保护作用（相对危险度= 0.53，95%CI = 0.30 - 0.91）。随机化后7 - 18个月。对照组有更多的门诊就诊（p <0.06），并且更有可能维持超过5000美元的住院费用（p <0.05）。运动可能对某些老年人亚组的跌倒率和医疗保健使用有有益的影响。在社区生活的成年人中，主要是步态，平衡和身体健康状况的轻度损伤，短期运动地图对这些损伤没有恢复作用。
Background. The study tested the effect of strength and endurance training on gait, balance, physical health status, fall risk, and health services use in older adults.Methods. The study was a single-blinded, randomized controlled trial with intention-to-treat analysis. Adults (n = 105) age 68-85 with at least mild deficits in strength and balance were selected from a random sample of enrollees in a health maintenance organization. The intervention was supervised exercise (1-h sessions, three per week for 24-26 weeks), followed by self-supervised exercise. Exercise groups included strength training using weight machines (n = 25). endurance training using bicycles (n = 25), and strength and endurance training (n = 25). Study outcomes included gait tests, balance tests, physical health status measures, self-reported falls (up to 25 months of follow-up). and inpatient and outpatient use and costs.Results. There were no effects of exercise on gait, balance, or physical health status. Exercise had a protective effect on risk of falling (relative hazard = .53, 95% CI = .30-.91). Between 7 and 18 months after randomization. control subjects had more outpatient clinic visits (p < .06)and were more likely to sustain hospital costs over $5000 (p < .05).Conclusions. Exercise may have beneficial effects on fall rates and health care use in some subgroups of older adults. In community-living adults with mainly mild impairments in gait, balance, and physical health status, shortterm exercise map not have a restorative effect on these impairments.
