BACKGROUND/AIM: Resistance training is an exercise modality at which overweight and obese adolescents can excel and which can therefore positively affect their psychological well-being. The aim of this study was to determine the effect of a 6-month resistance training intervention on the self-concept strength and body composition of overweight and obese adolescent males.
56 overweight and obese males aged 13-17 years were randomly allocated to an Intervention (n=30) or Control (n=26) group. Primary (psychological) and secondary (strength and body composition) outcomes were assessed at baseline as well as at 3 (halfway through the intervention), 6 (immediately postintervention) and 12 months follow-up. Random effects mixed modelling was used to determine the effects of the intervention.
Statistically significant differences between the Intervention and Control groups were observed at 3-month and 6-month assessments for exercise self-efficacy, resistance training confidence and self-esteem. Large increases in strength for the Intervention group, relative to Controls, were also observed with no substantial changes in body composition shown for either group. Values for all variables returned to baseline following completion of the programme.
A 6-month resistance training intervention can positively affect the self-concept and strength of overweight and obese adolescent boys.
背景/目的：阻力训练是超重和肥胖青少年能够擅长的运动方式，因此可以积极影响他们的心理健康。本研究的目的是确定 6 个月的抗阻训练干预对超重和肥胖青少年男性的自我概念强度和身体成分的影响。
56 名年龄在 13-17 岁的超重和肥胖男性被随机分配到干预组（n=30）或对照组（n=26）。在基线以及 3 个月（干预中途）、6 个月（干预结束后）和 12 个月随访时评估主要（心理）和次要（力量和身体成分）结局。使用随机效应混合模型来确定干预的效果。
在 3 个月和 6 个月的评估中，干预组在运动自我效能、抗阻训练信心和自尊方面与对照组存在统计学显著差异。与对照组相比，干预组的力量也有了较大的提高，而两组的身体成分都没有明显变化。完成计划后，所有变量的值均恢复到基线。
6 个月的抗阻训练干预可以积极影响超重和肥胖青少年男孩的自我概念和力量。
