University students sit too much, which is detrimental to their physical and mental health. Academic schedules, including scheduled education time and self-study time, may influence their physical activity behaviors.
To investigate (1) the association between scheduled education time and students' physical activity levels during weekdays; (2) the association between self-study time and students' physical activity levels during the weekdays and weekends.
126 (68 Maastricht University (UM); 58 KU Leuven (KUL)) first-year undergraduate students in biomedical sciences (mean ± age: 19.3 ± 1.0, BMI: 22.0 ± 3.0, 17% men, 83% women) completed a demographics questionnaire and reported their academic activities with a 7-day logbook. Furthermore, their physical activity behavior was measured with the activPAL monitor for 7 days. Linear mixed models were used to examine the associations between university (UM versus KUL), academic activities (scheduled education time and self-study time), and students' activity levels.
During weekdays, each hour of scheduled education time per day was significantly associated with a 1.3 min decrease of moderate to vigorous physical activity (MVPA) per day. Scheduled education time was not significantly associated with the sedentary time, light-intensity physical activity (LPA), and active sedentary behavior ratio. Each hour of self-study per day was significantly associated with 8 min more of sedentary time per day, 6 min less LPA per day, and 1.3 min less MVPA per day. Self-study time was not significantly associated with active sedentary behavior ratio. During the weekend, each hour of self-study time per day was associated with an additional 17.8 min of sedentary time per day and a reduction of 15.2 min of LPA per day. Self-study time was not significantly associated with the time spent doing MVPA and active sedentary behavior ratio.
It could be more effective to change students' physical activity behaviors during self-study than during scheduled education time. Therefore, offering a study environment that reduces sedentary behavior and promotes light-intensity physical activity, is crucial.
大学生久坐不利于身心健康。学业安排，包括规定的教育时间和自习时间，可能会影响他们的体育活动行为。
调查（1）规定的教育时间与学生工作日体育活动水平之间的关系；（2）自习时间与学生工作日和周末体育活动水平之间的关系。
126 名（马斯特里赫特大学（UM）68 名；鲁汶大学（KUL）58 名）生物医学科学一年级本科生（平均年龄±1.0 岁：19.3±1.0，BMI：22.0±3.0，17%男性，83%女性）完成了一份人口统计学调查问卷，并使用 7 天日志记录他们的学术活动。此外，他们的体育活动行为通过 activPAL 监测仪测量了 7 天。使用线性混合模型检验大学（UM 与 KUL）、学术活动（规定的教育时间和自习时间）与学生活动水平之间的关系。
在工作日，每天每小时的规定教育时间与每天中度至剧烈体力活动（MVPA）减少 1.3 分钟显著相关。规定的教育时间与久坐时间、低强度体力活动（LPA）和活跃性久坐行为比例没有显著关系。每天每小时的自习时间与每天增加 8 分钟的久坐时间、每天减少 6 分钟的 LPA 和每天减少 1.3 分钟的 MVPA 显著相关。自习时间与活跃性久坐行为比例没有显著关系。在周末，每天每小时的自习时间与每天增加 17.8 分钟的久坐时间和每天减少 15.2 分钟的 LPA 显著相关。自习时间与 MVPA 和活跃性久坐行为比例没有显著关系。
改变学生的自习时间比改变规定的教育时间更能有效改变学生的体育活动行为。因此，提供一个减少久坐行为和促进低强度体力活动的学习环境至关重要。
