Active commuting to and from school (ACS) has been recognized as a potential tool to improve physical fitness. Thus, this study aims to test the relationships between the average slope in the ACS and physical fitness, as well as to verify the mediator role of fatness in the relationship between average slope and physical fitness. A total of 257 participants, 137 boys and 120 girls, from 22 schools belonged to first and second High School grades participated in this study. Based on self-reported measure and Google Earth, participants were grouped into the active commuter (number of trips was ≥5, and the time of the trip was ≥15 min), mixed commuter (number of weekly trips was <5, and the time spent on the trip was <15 min) and passive commuter groups (those who reported traveling regularly by car, motorcycle, or bus). Specifically, in the active commuter group, a positive association between the average slope in the ACS with fatness was found, which in turn was positively related to strength lower limbs and cardiorrespiratory fitness. The average slope was not significantly associated with physical fitness indicators. Furtheremore, fatness did not mediate the relathionship between average slope and physical fitness. This research concluded positive associations between average slope and the body fat in the ACS. The tendency of findings signal that the average slope should be taken into account along with the distance, time and frequency of the active commuting.
上下学主动通勤（ACS）已被视为一种改善身体健康的潜在方式。因此，本研究旨在检验ACS中的平均坡度与身体健康之间的关系，并验证肥胖在平均坡度与身体健康关系中的中介作用。来自22所初高中的257名参与者（137名男生和120名女生）参与了本研究。基于自我报告测量和谷歌地图，参与者被分为主动通勤者（出行次数≥5次且每次出行时间≥15分钟）、混合通勤者（每周出行次数<5次且每次出行时间<15分钟）和被动通勤者组（那些报告经常乘坐汽车、摩托车或公交车出行的人）。具体而言，在主动通勤者组中，发现ACS中的平均坡度与肥胖之间存在正相关，而肥胖又与下肢力量和心肺适能呈正相关。平均坡度与身体适能指标无显著关联。此外，肥胖并未介导平均坡度与身体适能之间的关系。本研究得出ACS中的平均坡度与体脂之间存在正相关。研究结果表明，在考虑主动通勤的距离、时间和频率时，也应考虑平均坡度。
