BACKGROUND AND PURPOSE
While there has been considerable research on stretching, a paucity of research has focused on stretching of the calf muscle-tendon unit (MTU) in older women. Because limited ankle dorsiflexion range of motion (ROM) is associated with gait abnormalities and increases the risk of falls in the elderly, we investigated the effect of static stretching on flexibility of the calf MTU of healthy elderly adults.
METHODS
Twenty healthy female volunteers, 76 to 91 years of age, were recruited from Linda Valley Villa, an independent living center. Subjects performed a static stretching program 5 days a week for 6 weeks. Passive ankle dorsiflexion ROM was taken prior to beginning the stretching program and 3 days after the last stretching day.
RESULTS
Mean increase in passive ankle dorsiflexion ROM was 12.3 degrees (SD= 4.4 degrees ) (p < .001).
CONCLUSION
A 6-week stretching program is capable of provoking a significant increase in ankle dorsiflexion ROM for elderly women.
背景与目的
虽然已有大量关于拉伸的研究，但针对老年女性小腿肌-腱单元（MTU）拉伸的研究却很少。由于踝关节背屈活动范围（ROM）受限与步态异常相关，并增加老年人跌倒风险，我们研究了静态拉伸对健康老年成年人小腿MTU柔韧性的影响。
方法
从独立生活中心琳达谷别墅招募了20名年龄在76至91岁之间的健康女性志愿者。受试者每周进行5天的静态拉伸计划，持续6周。在开始拉伸计划前和最后一次拉伸日之后3天测量被动踝关节背屈ROM。
结果
被动踝关节背屈ROM平均增加12.3度（标准差=4.4度）（p<.001）。
结论
为期6周的拉伸计划能够使老年女性的踝关节背屈ROM显著增加。
