Hand-grip strength, elbow flexion strength, trunk extension strength and knee extension strength, and body composition (measured by densitometry) were measured in 59 male students (mean 19.2 years) in order to compare the muscle strength of obese men, in relation to fat storage rate (% fat), with those of non-obese men. Their % fat ranged from 6.2-35.6%. Correlations of body weight and lean body mass were found to be significant with each muscle strength. Our findings presented that obese men had lower muscle strengths for body weight and lean body mass than non-obese men do. This might be the result of two characteristics, inactivity and weak willpower, of obese men. Besides, the 20% fat of threshold of obesity for men proposed by Behnke and Wilmore was reasonable from the viewpoint of the muscle strength because of the differences between group D (18.8% fat) and group E (23.8% fat).
为了比较肥胖男性与非肥胖男性的肌肉力量，对59名男性学生（平均年龄19.2岁）进行了握力、肘屈肌力量、躯干伸展肌力量和膝伸展肌力量以及身体成分（通过密度测定法测量）的测量，他们的体脂率在6.2%-35.6%之间。发现体重和去脂体重与每种肌肉力量之间存在显著相关性。我们的研究结果表明，肥胖男性相对于体重和去脂体重的肌肉力量低于非肥胖男性。这可能是肥胖男性不活动和意志力薄弱这两个特征导致的结果。此外，从肌肉力量的角度来看，由于D组（体脂率18.8%）和E组（体脂率23.8%）之间的差异，Behnke和Wilmore提出的男性肥胖阈值20%的体脂率是合理的。
