Fear of injury is reported as a barrier to exercise by older adults. However, the literature is limited in describing exercise injuries in older adults.
This study prospectively evaluated the 12-month incidence of exercise-related injuries to community-dwelling older adults (n=167 respondents; 63 men, 104 women; mean age 69±5 year).
A questionnaire developed for use in older adults was administered to document self-reported injuries. Linear regression analysis was conducted to identify covariates related to injury outcomes.
23 people (14%) reported injuries. 41% of injuries were to the lower extremities, where the most common type was overuse muscle strains (32%, n=7). Overexertion was the most common cause of injury (n=9) and walking accounted for half of the activities during which injury occurred. 70% of injuries required medical treatment. 44% were not able to continue exercising after injury and return-to-activity time varied from 1 to 182 days. Sex, age and exercise volume were not significantly associated with injury occurrence.
These results showed similar, or lower, exercise-related injury rates as compared with previous reports on younger and middle-aged adults; however, the definition of, and criteria for, 'injury' reporting varies in the literature. This study indicates that older adults taking up exercise are not at increased risk of injury versus younger age groups.
受伤恐惧被报道为老年人运动的障碍。然而，文献在描述老年人的运动损伤方面有限。
本研究前瞻性评估了社区居住的老年人（n=167 名受访者；63 名男性，104 名女性；平均年龄 69±5 岁）进行 12 个月的运动相关损伤发生率。
为老年人开发的问卷用于记录自我报告的损伤。进行线性回归分析以确定与损伤结果相关的协变量。
23 人（14%）报告了损伤。41%的损伤发生在下肢，最常见的类型是过度使用肌肉拉伤（32%，n=7）。过度用力是最常见的损伤原因（n=9），受伤时一半的活动是在行走。70%的损伤需要医疗治疗。44%的人在受伤后无法继续锻炼，恢复活动时间从 1 天到 182 天不等。性别、年龄和运动量与损伤发生无显著相关性。
这些结果显示，与之前关于年轻和中年成年人的报告相比，运动相关的损伤率相似或更低；然而，文献中“损伤”报告的定义和标准不同。本研究表明，与年轻年龄组相比，开始运动的老年人受伤的风险没有增加。
