Abstract


Body Composition study is to understand the human body, health and the degree of aging, in order to facilitate the rational implementation of an effective way to control weight, body fat and lean body mass ratio of two parts suitable, thereby reducing the incidence of obesity-related diseases, enhance physical fitness, promote health, improve quality of life. Adolescent children to adulthood transition period is the most important period in the life, and the second peak of human growth and development, physical fitness and health levels of this period a direct impact on adult physical fitness, intelligence and the ability to work, aging and adult life has a certain relationship. This study selected Beijing 70 Middle School students for the study to explore young people aged 12 to 15 boys and girls, bone age of the boys aged 13 to 15 years of age and bone age of girls aged 12 to 14 years old, body mass index (BMI) is divided into underweight group, normal, overweight and obese group four different body to discuss this period of boys and girls in four body changes in body composition characteristics, factors affecting body composition changes, and the establishment of the applicable body composition evaluation formula. Questionnaire and measurements (body shape method, method of skinfold thickness, bioelectrical impedance and dual-energy X-ray absorptiometry), respectively, on the same subject test and measurement of dual-energy X-ray absorptiometry The results are used as the criterion. So as to explore suitable (biological age of 13 to 15-year-old boys and girls 12 to 14 years old) young people to use a simple, effective and accurate evaluation methods and estimates of the percentage of body fat and body fat rate formula. Results: 1 12 to 15-year-old adolescent boys and girls body composition changes slightly different characteristics. Boys and girls in body composition and BMI is proportional to its male and girls body fat content and muscle content and bone mineral changes were positively correlated with BMI changes. With the increase of body mass index (BMI), body fat rate and body fat percentage are up in trends, the slim group and the overweight and obese groups between the percentage of body fat there is a significant difference (P lt; 0.01). Boys and girls between the rise and there are differences, but the male, girls accumulation of fat distribution parts. 3 young boys and girls body fat rate impact of changes in factors exist. Changes in body fat percentage of boys and girls living habits, eating behavior and nutritional intake factors and daily physical activity and physical exercise behavioral factors, boys water intake, snacking, eating fast food frequency increased, increased frequency of meat and day longer students a higher percentage of body fat, girls performance of the amount of drinking water, staple food to eat pasta increased frequency, meal devour an increase in the amount of staple food, meat increased frequency and sit for longer periods of time students a higher percentage of body fat . 4 men, girls body fat percentage change and the relationship between genetic factors: father's body mass index (BMI) have a significant impact on the boys body mass index (BMI); Conversely, the parents body mass index (BMI) for girls body mass index (BMI ) have no significant impact. Skinfold thickness the BIA measurement results and previous developed projection formula and measured by DEXA body fat rate a good correlation between the BIA and DEXA measurement of body fat rate consistency is better, but the BIA and predecessors developed skinfold thickness formula there are some errors in the youth body fat percentage value measured by DEXA body fat percentage values. Conclusion: In this study, body mass index (BMI) as the basis of the derivation of the formula, skinfold thickness was established by the derivation of body fat rate formula has good reliability and validity, the derivation of the formula is as follows: boys 13 to 15-year-old biological age abdominal skinfold, the body fat rate = 3.221 0.816 × 0.936 × triceps skinfold -0.691 × scapular skinfold biological age of girls 12 to 14-year-old body fat rate = -1.017 0.474 × thigh skinfold 0.533 × brachial Ministry of triceps skinfold 0.335 × 0.254 × abdominal skinfold calf skinfold
