背景：由于测量的局限性，确保健康老龄化的习惯性身体活动的最佳模式仍不清楚；尽管有证据表明问卷的可靠性/有效性和活动模式的季节性变化有限，但大多数调查人员使用主观问卷或仅限于一周的加速度计或计步器测量。目的：本研究探讨了身体健康指标（步行能力、上肢和下肢等长力量以及静态和动态平衡）与表面上健康的老年人常年计步器/加速度计评估习惯性身体活动的数量和质量之间可能存在的关联。方法：受试者为 76 名男性和 94 名女性日本人，年龄 65-84 岁。每位参与者佩戴计步器/加速度计 1 年；测量结果包括每天的平均步数以及代谢当量 (MET) > 3 强度的活动持续时间。依从性良好，仪器被移除的时间间隔 > 3 小时
Background: Optimal patterns of habitual physical activity to ensure healthy aging remain unclear because of measurement limitations; most investigators have used either subjective questionnaires, or accelerometer or pedometer measurements limited to a single week, despite evidence of both the limited reliability/validity of questionnaires and seasonal changes in activity patterns. Objective: This study explored possible associations between indicators of physical fitness (walking ability, upper-and lower-extremity isometric strength, and static and dynamic balance) and yearlong pedometer/accelerometer assessments of the quantity and quality of habitual physical activity in ostensibly healthy older adults. Methods: Subjects were 76 male and 94 female Japanese aged 65-84 years. Each participant wore a pedometer/accelerometer for 1 year; measurements included the average number of steps taken each day and the duration of activity at an intensity of >3 metabolic equivalents (METs). Compliance was good, the instrument being removed for intervals of >3 h on
