OBJECTIVE
To examine the relations of sex, exercise self-efficacy, outcome expectations, and social support with meeting physical activity guidelines (PAGs).
PARTICIPANTS
Three hundred ninety-six college students participated in this study in the summer 2013.
METHODS
Students completed online questionnaires that assessed physical activity behaviors and psychosocial factors (ie, self-efficacy, outcome expectancies, and social support). Students' physical activity profile was categorized as meeting no PAGs, meeting aerobic PAGs only, meeting muscle-strengthening PAGs only, or meeting both PAGs.
RESULTS
A multinomial logistic regression revealed that students' sex and psychosocial factors significantly affected the odds of meeting any and all PAGs. Sex significantly moderated the relationship between outcome expectancy and meeting aerobic PAGs and between outcome expectancy meeting muscle-strengthening PAGs.
CONCLUSIONS
Results indicate that interventions designed to increase psychosocial factors may increase the likelihood of students meeting any and all PAGs. Social support may be especially beneficial for increasing muscle-strengthening activity.
目的
探讨性别、运动自我效能、结果期望和社会支持与达到身体活动指南（PAGs）之间的关系。
参与者
2013年夏季，396名大学生参与了本研究。
方法
学生完成在线问卷，评估身体活动行为和心理社会因素（即自我效能、结果期望和社会支持）。学生的身体活动情况分为未达到任何PAGs、仅达到有氧运动PAGs、仅达到肌肉强化PAGs或同时达到两种PAGs。
结果
多项逻辑回归显示，学生的性别和心理社会因素显著影响达到任何和所有PAGs的几率。性别显著调节了结果期望与达到有氧运动PAGs之间以及结果期望与达到肌肉强化PAGs之间的关系。
结论
结果表明，旨在增加心理社会因素的干预措施可能会增加学生达到任何和所有PAGs的可能性。社会支持可能对增加肌肉强化活动特别有益。
