通过对20~59岁城市中非体力劳动者的体成分分析,随年龄变化身体成分和脂肪分布变化特点及肥胖发展趋势研究,为在不同年龄段及不同性别城市非体力劳动者的运动处方提供理论依据。结论表明:1)20~59岁城市非体力劳动者男性、女性体脂率随年龄递增呈逐渐增加的趋势,人体内矿物质含量、蛋白质总量随年龄增加呈先升后降趋势,腰臀比、BMI和内脏脂肪水平均随年龄的递增,呈逐渐增加趋势。2)男性、女性身体脂肪含量随年龄增长逐渐增大,且女性的增幅大于男性。男性在进入30岁以后脂肪含量较前一年龄段明显增加,在40~49岁年龄段身体的脂肪含量达到峰值,女性到50~59岁年龄段身体的脂肪含量达到峰值。3)随年龄增长,男性的躯干脂肪率明显大于女性,上肢和下肢脂肪率方面明显小于女性,表明男性更多的脂肪集中在躯干部位,分布呈中心型肥胖。而女性更多脂肪集中在躯干下肢部位。
Through the body composition analysis of 20 to 59-year-old urban Chinese non-manual workers, changes of body composition and fat distribution with age, and development trend of obesity, it provides a basis for the exercise prescription of non-manual workers in different age groups and in different gender cities Theoretical basis. The conclusions are as follows: 1) The body fat percentage of male and female non-manual workers aged 20-59 years tends to increase gradually with age. The content of minerals and protein in the body increases first and then decreases with the increase of age, Ratio, BMI and visceral fat levels are increasing with age, showing a gradual increase. 2) Male and female body fat content increases with age, and women’s increase is greater than men’s. After entering the age of 30, men have significantly increased their fat content compared with the previous age group. The body fat content reaches the peak in the age group of 40-49 years. The body fat content reaches the peak in women aged 50-59 years. 3) With age, male body fat rate was significantly greater than the female, upper limbs and lower limb fat percentage was significantly less than women, suggesting that more male fat in the trunk area, the distribution was central obesity. And more fat in women concentrated in the lower extremities of the trunk area.
