We determined the effect of supervised physical training without dietary intervention, on body composition of obese girls. The subjects were 25 obese 7- to 11-year-old black girls, divided into physical training and lifestyle education groups which were comparable on baseline body composition; 22 girls finished all aspects of the study. Twelve girls engaged in aerobic training (10 weeks, 5 days/week) while 10 engaged in weekly lifestyle discussions without formal physical training. Total body and regional body composition were measured with dual energy x-ray absorptiometry, skinfolds and circumferences. Aerobic fitness was measured by heart rate response to submaximal treadmill exercise. The physical training group attended 94% of scheduled sessions and kept their heart rates at an average of 163 bpm for 28 minutes/session. The lifestyle group attended 95% of their sessions; they remained stable in aerobic fitness and most body composition measurements. The physical training group showed a significant improvement in aerobic fitness and a significant decline of 1.4% body fat. Skinfold and circumference indices of fatness also declined significantly in the training group. We conclude that controlled physical training, without dietary intervention, improved the fitness and body composition of obese black girls.
我们确定了在无饮食干预情况下的监督性体育训练对肥胖女孩身体成分的影响。受试者为25名7至11岁的肥胖黑人女孩，分为体育训练组和生活方式教育组，两组在基线身体成分方面具有可比性；22名女孩完成了研究的各个方面。12名女孩进行有氧训练（为期10周，每周5天），而10名女孩参与每周的生活方式讨论但无正规体育训练。采用双能X线吸收法、皮褶厚度和围度测量全身及局部身体成分。通过次极量跑步机运动时的心率反应来测量有氧适能。体育训练组参加了94%的预定课程，每次课程平均28分钟，心率保持在163次/分钟。生活方式组参加了95%的课程；她们的有氧适能和大多数身体成分测量值保持稳定。体育训练组的有氧适能有显著改善，体脂显著下降了1.4%。训练组的皮褶厚度和围度肥胖指数也显著下降。我们得出结论，在无饮食干预情况下的控制性体育训练改善了肥胖黑人女孩的适能和身体成分。
