The effects of exercise on lean body mass (LBM), fat mass (FM), maximal oxygen uptake (VO2max), and quadriceps (QD) strength were studied in 72 male, mildly obese (X = 38% fat) subjects (X age, 43.5 yr) randomly assigned to one of eight treatments arranged in a 2 X 4 factorial plan with exercise (EX) and non-exercise (NE) and four diets as the two factors. Exercise consisted of a 3 d/wk, 8-wk aerobics program (70-85% maximum heart rate) accompanied by a calisthenics program. LBM was determined by whole body potassium (40K), FM by subtracting LBM from total body weight, VO2max using the Wilmore-Costill method, and QD strength with the Cybex II system. Weight loss of the combined EX (11.8 +/- 0.6 kg) (X +/- SE) and NE (9.2 +/- 0.3 kg) groups was not statistically different. LBM of the EX group was unchanged (from 63.1 +/- 1.9 to 62.5 +/- 2.1 kg), whereas in the NE group it was reduced from 62.6 +/- 1.1 to 59.3 +/- 1.2 kg (P less than 0.001) accounting for 36% of total weight loss. FM loss was greater for the EX group (11.2 +/- 1.5 kg) when compared to the NE (5.2 +/- 1.6 kg) group (P less than 0.001). The EX group exhibited an increase in VO2max from 2.9 +/- 0.3 to 3.4 +/- 0.2 1 X min-1 (P less than 0.001), whereas the NE group was unchanged (3.0 +/- 0.3 to 2.9 +/- 0.4 1 X min-1 (NS].(ABSTRACT TRUNCATED AT 250 WORDS)
在72名轻度肥胖（平均体脂率38%）的男性受试者（平均年龄43.5岁）中，研究了运动对瘦体重（LBM）、脂肪量（FM）、最大摄氧量（VO2max）和股四头肌（QD）力量的影响。这些受试者被随机分配到八种处理方式中的一种，该实验采用2×4析因设计，以运动（EX）和不运动（NE）以及四种饮食作为两个因素。运动包括每周3天、为期8周的有氧运动计划（最大心率的70 - 85%）以及一套健身操计划。LBM通过全身钾（40K）测定，FM通过总体重减去LBM得出，VO2max采用威尔莫尔 - 科斯蒂尔法测定，QD力量用Cybex II系统测定。运动组（11.8±0.6 kg）（均值±标准误）和不运动组（9.2±0.3 kg）的体重减轻在统计学上无差异。运动组的LBM未改变（从63.1±1.9 kg降至62.5±2.1 kg），而不运动组的LBM从62.6±1.1 kg降至59.3±1.2 kg（P＜0.001），占总体重减轻的36%。与不运动组（5.2±1.6 kg）相比，运动组的FM减少量更大（11.2±1.5 kg）（P＜0.001）。运动组的VO2max从2.9±0.3升至3.4±0.2 l·min-1（P＜0.001），而不运动组无变化（3.0±0.3至2.9±0.4 l·min-1（无显著差异）]。（摘要截断于250字）
