背景和目的日本成年人缺乏按年龄和性别划分的机车和非机车体力活动(PA)的比较数据。本研究的目的是用区分机车和非机车PA的三轴加速度法，客观地调查居住在日本的不同性别成年人和老年人各强度PA的水平。方法对关东地区18~92岁的571名女性和315名男性，用三轴加速度计(Active Style Pro：HJA-350IT)进行连续6天的PA测试，并评估按代谢当量分类的轻、中、剧烈运动分钟数(MVPA)。结果70岁以上的日本老年女性，不仅在机车PA(轻度和MVPA)上花费的时间较少，而且在非机车MVPA上花费的时间也较少。然而，对于非机车轻活动，70岁以上的女性和年轻女性之间没有显著差异。相比之下，对于男性来说，非机车轻活动和MVPA随着年龄的增长保持不变，而70岁以上的老年男性花在机车活动(轻活动和MVPA)上的时间较少。除老年人MVPA外，女性从事非机车活动的时间明显多于男性，且女性在非机车MVPA中的时间占各年龄组MVPA的一半以上。结论日本人的PA强度和类型明显受年龄的影响，而男性的运动性PA和日本女性的非机车轻度PA明显不受年龄的影响。这一发现还表明了性别差异。因此，在PA的总体评估中，对机车和非机车活动的评估是重要的。
Background and Aims Comparative data on locomotive and non-locomotive physical activity (PA) by age and gender are lacking for Japanese adults. The purpose of this study was to investigate objectively the levels of PA in each intensity in adults and older people by both genders living in Japan with triaxial accelerometry with discrimination between locomotive and non-locomotive PA.Methods In 571 women and 315 men aged 18-92 years from the Kanto region, PA was assessed for 6 consecutive days with a triaxial accelerometer (Active style Pro: HJA-350IT), and minutes of light and moderate-to-vigorous physical activity (MVPA) classified by metabolic equivalents were evaluated.Results Japanese elderly women over 70 years, spent less time in not only locomotive PA (light and MVPA), but also in non-locomotive MVPA. For non-locomotive light activity, however, there was no significant difference between women over 70 years and younger women. In contrast, for men, non-locomotive light activity and MVPA remained constant with age, while elderly men over 70 years spent less time in locomotive activities (light and MVPA). Women spent more time in non-locomotive activity than men, except for MVPA in elderly individuals, and time in non-locomotive MVPA occupied more than half of the total MVPA in all age groups for women.Conclusions These findings suggest that the intensity and the type of PA for Japanese were obviously affected by age, while locomotive PA for men and non-locomotive light PA for Japanese women were obviously unaffected by age. The finding also indicates gender differences. Thus, evaluation of both locomotive and non-locomotive activity is important in the overall assessment of PA.
