The study investigated associations between selected physical activity correlates among 299 adolescents (90 boys, age 12-14 years) from 3 English schools. Physical activity was assessed by self-report and accelerometry. Correlates represented biological, predisposing, and demographic factors as described in the Youth Physical Activity Promotion Model. Boys engaged in more self-reported (p < .01) and accelerometer assessed physical activity than girls (p = .02). Positive associations between sex (male), BMI, Perceived PE Ability, Perceived PE Worth, number of enrolled students, and physical activity outcomes were evident (p < .05). School-based physical activity promotion should emphasize sex-specific enhancement of students' perceived PE competence and enjoyment.
该研究调查了来自3所英国学校的299名青少年（90名男孩，年龄在12至14岁之间）中选定的身体活动相关因素之间的关联。通过自我报告和加速度计评估身体活动。相关因素代表了青少年身体活动促进模型中描述的生物学、易感性和人口统计学因素。男孩自我报告的身体活动（p <.01）和加速度计评估的身体活动比女孩更多（p =.02）。性别（男性）、BMI、感知到的体育能力、感知到的体育价值、在校学生人数与身体活动结果之间存在明显的正相关（p <.05）。基于学校的身体活动促进应强调针对性别提高学生对体育能力的感知和享受。
