研究人员对年龄在65-83岁之间的41名男性和54名女性进行了性别、年龄、季节和习惯性身体活动的相互作用研究，使用计步器/加速计来确定一整年每24小时的步数和身体活动量（3个代谢当量[METs]）。男性的这三项指标均高于女性。在女性中，年龄与步数和活动代谢当量呈负相关。无论性别和年龄，3项活动变量均在冬季较低，春季和秋季达到高峰。在夏季，步数与年平均值相匹配，但活动3 METs的持续时间分别比其他季节长和短。这些发现对那些促进老年人体育锻炼的人具有实际意义。
The interactions of sex, age, season, and habitual physical activity were examined in 41 male and 54 female Japanese age 65-83 yr, using a pedometer/accelerometer that determined step counts and amounts of physical activity (3 metabolic equivalents [METs]) throughout each 24-hr period for an entire year. All 3 measures were greater in men than in women. In women, age was negatively correlated with step count and activity 3 METs. Irrespective of sex or age, all 3 activity variables were low in the winter, peaking in spring or autumn. In the summer, step counts matched the annual average, but durations of activity 3 METs were, respectively, longer and shorter than in other seasons. These findings have practical implications for those promoting physical activity for older adults.
