The level, direction or presence of the relationship between perceived physical activity (PA) participation and physical fitness (PF) in children may differ by gender and this will assist in designing gender-specific interventions to promote PA participation, which in turn improves PF levels.
This study aimed to establish the moderating effect of gender on the relationship between perceived PA participation and PF.
A cross-sectional study was conducted with a cohort of 870 primary school children aged 9-14 years old. Perceived PA participation was measured using the PAQ-C questionnaire while PF levels were measured using cardiorespiratory endurance (i.e. VO2 max).
The results showed significant gender differences for perceived PA participation levels ( = -3.40, ≤ 0.001) and PF ( = -11.59, ≤ 0.001), with boys reporting higher levels than the girls. Perceived PA participation had a positive, weak and statistically significant correlation with PF ( 0.251; ≤ 0.001). Gender significantly moderates the relationship between perceived PA participation and PF (β = 3.518; 95% confidence interval [CI]: 0.642 to 6.395; 0.017).
The moderating effect of gender on the relationship between perceived PA participation and PF highlights the differences in physiology as well as the societal PA associated roles played by boys and girls.
The study has established that the relationship between perceived PA participation and PF is more pronounced among boys than girls.
儿童感知到的身体活动（PA）参与度与身体素质（PF）之间关系的程度、方向或存在情况可能因性别而异，这将有助于设计针对性别的干预措施来促进PA参与，进而提高PF水平。
本研究旨在确定性别对感知到的PA参与度与PF之间关系的调节作用。
对870名9 - 14岁的小学生进行了一项横断面研究。使用PAQ - C问卷测量感知到的PA参与度，同时使用心肺耐力（即最大摄氧量）测量PF水平。
结果显示，在感知到的PA参与度水平（t = -3.40，p ≤ 0.001）和PF（t = -11.59，p ≤ 0.001）方面存在显著的性别差异，男孩报告的水平高于女孩。感知到的PA参与度与PF呈正相关，相关性较弱但具有统计学意义（r = 0.251；p ≤ 0.001）。性别显著调节了感知到的PA参与度与PF之间的关系（β = 3.518；95%置信区间[CI]：0.642至6.395；p =
