The considerable changes in physical activity (PA) during the transition to university are likely associated with changes in PA constraints during this transition. The purpose of this study was to examine changes in PA and associated constraints among first-year university students during the transition to university. Data concerning sociodemographic characteristics, PA behaviors, and changes in PA and constraints were collected from 121 first-year New Zealand university students via an online survey. Data were analyzed using quantitative and qualitative methods. Findings revealed that following the transition, PA declined significantly, that PA participation patterns/trends had changed (from team/group sports to individual activities and to less competitive and/or more social activities), and that changes in constraints (intrapersonal, interpersonal, and time management) may have influenced changes. Findings shed light on how changes in constraints potentially influence PA following the transition and provide evidence to inform the development of policies and interventions to promote student PA.

过渡到大学期间身体活动（PA）的显着变化可能与此过渡期间PA约束的变化有关。这项研究的目的是研究在过渡到大学一年级大学生中PA的变化和相关的限制。通过在线调查收集了来自121位一年级的新西兰大学生的有关社会人口统计学特征，PA行为以及PA和约束变化的数据。使用定量和定性方法分析数据。调查结果表明，过渡后，巴勒斯坦权力机构显着下降，巴勒斯坦权力机构的参与模式/趋势发生了变化（从团队/小组运动变为个人活动，到竞争性和/或社交性较弱的活动），并且约束条件发生了变化（人际关系，人际关系和时间管理）可能已影响到变化。调查结果揭示了过渡后约束条件的变化可能如何影响PA，并提供了证据来指导政策和干预措施的发展，以促进学生PA的发展。
