Exercise epidemiology on physical inactivity and exercise amotivation

本研究考察了缺乏运动与健康结果之间的关系，以及逃避运动行为中预先考虑的因素。结果表明，高强度体育活动而非缺乏体育活动是大学生6个月后心理健康状况不佳的预防因素。静坐时间越长，运动预观行为发生的频率越高，运动俱乐部是运动预观行为发生的预防因素。加速度计测量的坐着时间与中年人心脏代谢危险因素显著相关，在控制中高强度体力活动水平后与老年人体重指数显著相关。

The present study examined the association between physical inactivity and health outcomes and escaping factors from pre-contemplators in exercise behavior. As a results, high-intensity physical activity, not physical inactivity, was preventive factor for poor mental health after 6 months in university male students. More sitting time was associated with more frequent pre-contemplators in exercise behavior, and sports club was preventive factor from pre-contemplators in exercise behavior. Accelerometer-measured sitting time was significantly related to cardiometabolic risk factors in middle aged, and was significantly related to body mass index in the elderly after controlling for moderate and vigorous intensity physical activity level.
