摘要

摘要研究目的:大量数据表明,身体脂肪储存受到遗传和环境因素的复杂调节,包括身体活动。然而,大多数研究并没有在建议的体脂限制中考虑到生活方式的这一方面。在这种情况下,美国运动委员会(ACE)似乎提供了一种更精确、更可靠的体脂分类,它不仅根据性别,而且根据活动水平来区分个体。材料和方法:共有793名学生(312名久坐学生和481名活跃学生)自愿参加了这项研究。在久坐不动的参与者中,男性147人,女性165人。活跃受试者中男性206人,女性275人。活跃的受试者根据研究计划进行不同模式的身体活动。计算了所有参与者的身体质量指数(BMI)。在BMI为18.5-24.9和BMI≥25的参与者中,通过四项皮褶测量来确定体脂。之后,参与者根据美国运动委员会(ACE)提供的男性和女性体脂百分比(必需脂肪、运动员、健康、平均脂肪和肥胖脂肪)进行分类。结果:BMI为18.5-24.9的久坐和活跃的男性没有高(肥胖)脂肪。相比之下,在BMI≥25的久坐男性中,16.4%的人肥胖,而肥胖的活动者为1.8%。在久坐不动的女性中,BMI从18.5到24.9不排除肥胖,16.9%的参与者存在肥胖。在BMI≥25的久坐女性中,大多数受试者(97.1%)肥胖。相比之下,在BMI≥25的活跃女性中,平均脂肪和肥胖脂肪的比例相似(分别为53.3%和46.7%)。讨论:我们的研究清楚地表明,BMI作为一种简单的身体成分衡量标准,在体育活动的男女学生中提供了关于真正肥胖的错误信息。相似的身体质量指数并不能排除久坐和活跃学生体内脂肪百分比的显著差异。

Body fatness in sedentary and active students with different body mass index
Abstract Study aim: Numerous data have indicated that body fat stores undergo complicated regulation by genetic and environmental factors, including physical activity. However, the majority of studies did not take into account this aspect of lifestyle in proposed body fat limits. In this context it seems that a more precise and reliable classification of body fat is provided by the American Council on Exercise (ACE), which distinguishes individuals not only with respect to sex but also activity level. Material and methods: A total of 793 students (312 sedentary and 481 active) volunteered to participate in the study. Among sedentary participants 147 were male and 165 female. Among active subjects 206 were male and 275 were female. Active subjects were engaged in different modes of physical activity according to the study program. In all participants body mass index (BMI) was calculated. In participants with BMI 18.5–24.9 and BMI ≥ 25 body fat was determined using four skinfold measurements. Thereafter participants were classified according to the percentage of body fat using ranges for males and females provided by the American Council on Exercise (ACE) (essential fat, athletes, fitness, average and obese fatness). Results: None of the sedentary and active males with BMI 18.5–24.9 had high (obese) fat. In contrast, in sedentary males with BMI ≥ 25 16.4% were obese vs. 1.8% of obese active ones. In sedentary females BMI from 18.5 to 24.9 did not exclude obesity, which was found in 16.9% of participants. In sedentary females with BMI ≥ 25 most of the subjects (97.1%) were obese. In contrast, in active females with BMI ≥ 25 a similar percentage of participants had average and obese fat (53.3% and 46.7, respectively). Discussion: Our study clearly demonstrated that BMI as a simple measure of body composition provides false information concerning true adiposity in physically active male and female students. A similar BMI did not exclude marked differences in the percentage of body fat in sedentary and active students.

期刊介绍: The leading idea is the health-directed quality of life. The journal thus covers many biomedical areas related to physical activity, e.g. physiology, biochemistry, biomechanics, anthropology, medical issues associated with physical activities, physical and motor development, psychological and sociological issues associated with physical activities, rehabilitation, health-related sport issues and fitness, etc.
