The personality trait self-control has been associated with various adaptive outcomes. The objective of this cross-sectional study was to explore whether self-control is associated with self-reported leisure time physical activity (LTPA), Body Mass Index (BMI), muscle-fitness and aerobic fitness among young men. Participants (482 male conscripts; age M = 20) completed a questionnaire and participated in anthropometric measurements in the DefenceNutri Study, and took standard aerobic fitness and muscle fitness tests as part of their military training. Self-control was found to have a positive association with LTPA, aerobic fitness, and muscle fitness, and a negative association with BMI. Self-control predicted aerobic and muscular fitness regardless of BMI, and remained a significant and independent predictor of aerobic fitness (R² (adj.) = .28, β = .10, p < .05), but not muscle fitness, when LTPA and BMI were controlled for.
性格特质自控力与各种适应性结果相关。本横断面研究旨在探究自控力是否与年轻人的自我报告闲暇时间体力活动（LTPA）、身体质量指数（BMI）、肌肉力量和有氧适能相关。研究对象为 482 名男性新兵（年龄 M=20），他们完成了一份问卷并参加了国防营养研究的人体测量，同时作为军事训练的一部分进行了标准的有氧适能和肌肉力量测试。研究发现，自控力与 LTPA、有氧适能和肌肉力量呈正相关，与 BMI 呈负相关。无论 BMI 如何，自控力都可以预测有氧适能和肌肉力量，而且当控制 LTPA 和 BMI 时，它仍然是有氧适能的显著且独立的预测因素（R²(adj.)=.28，β=.10，p<.05），但不是肌肉力量。
