Body size estimation (BSE) and locus of control (LOC) were studied in 18 obese adolescent boys undergoing weight reduction. The subjects attended a seven-week summer camp which offered both increased activity and a 1200 kcal (5023 kJ)/d diet, resulting in an average weight loss of 29.2 +/- 6.3 lb (13.3 +/- 2.9 kg) and a decrease in body fat from 39.0 percent +/- 0.6 percent to 27.5 percent +/- 4.3 percent. Fatness was correlated with poor physical performance [1.5 mile (2.4 km) runs]. Weight reduction and decreased body fat resulted in an improved running time. BSE was assessed using self photographs distorted by an anamorphic lens. While subjects could correctly estimate their body size prior to weight reduction, after weight reduction they significantly underestimated body size. This finding contrasts with adults with juvenile-onset obesity who overestimate body size after weight reduction. LOC (measured by Nowicki-Strickland LOC Inventory) changed in the direction of internality after weight reduction. The use of exercise with the weight loss program may thus improve feelings of control and prevent overestimation of body size.
对18名接受减肥治疗的肥胖青少年男性进行了身体大小估计（BSE）和控制点（LOC）研究。受试者参加了一个为期七周的夏令营，该夏令营提供了更多的活动以及每天1200千卡（5023千焦）的饮食，结果平均体重减轻了29.2±6.3磅（13.3±2.9千克），身体脂肪从39.0%±0.6%降至27.5%±4.3%。肥胖与身体机能差（1.5英里（2.4千米）跑）相关。体重减轻和身体脂肪减少导致跑步时间缩短。使用变形镜头扭曲的自拍照来评估BSE。虽然受试者在减肥前能够正确估计自己的身体大小，但减肥后他们显著低估了身体大小。这一发现与青少年期起病的肥胖成年人在减肥后高估身体大小形成对比。减肥后，LOC（通过诺维茨基 - 斯特里克兰德LOC量表测量）向内控方向转变。因此，在减肥计划中使用运动可能会改善控制感并防止对身体大小的高估。
