This experiment compared the effects of aerobic-training (AT) versus strength-training (ST) on body image among young women with pre-existing body image concerns. Theory-based correlates of body image change were also examined. Participants were 46 women (M age=21.5 years), randomly assigned to an 8-week AT or ST intervention consisting of supervised exercise 3 days/week. Multidimensional measures of body image were administered pre- and post-intervention, along with measures of physical fitness, perceived fitness, and exercise self-efficacy. Women in the AT condition reported greater reductions in social physique anxiety (p=.001) and tended to report greater improvements in appearance evaluation (p=.06) than women in the ST condition. Changes in perceived fatness, perceived aerobic endurance and aerobic self-efficacy were significantly correlated with body image change (ps<.003). Results provide direction for prescribing exercise to improve body image and advancing theory to account for the effects of exercise.
本实验比较了有氧运动训练（AT）与力量训练（ST）对已有身体意象问题的年轻女性身体意象的影响。还研究了基于理论的身体意象变化相关因素。参与者为46名女性（平均年龄=21.5岁），她们被随机分配到一个为期8周的AT或ST干预组，干预包括每周3天的有监督锻炼。在干预前后进行了身体意象的多维测量，同时还测量了身体素质、感知到的健康状况和运动自我效能。与ST组女性相比，AT组女性报告社交体型焦虑有更大程度的降低（p=0.001），并且在外表评价方面往往有更大改善（p=0.06）。感知到的肥胖程度、感知到的有氧耐力和有氧自我效能的变化与身体意象变化显著相关（p<0.003）。研究结果为通过规定运动来改善身体意象以及推进解释运动效果的理论提供了方向。
