Research On The Body Fat Distribution And Speculate Formula Of Adult Female In Shanghai

In this research we selected adult female(30-54 years old)as the research object, and measured the body fat percentage through skin fold fat thickness and bioelectric impedance analysis, based on knowing the growth and distribution of their body fat. And the important is to analyze the impact of body fat distribution and variation by fitness. We measured the body fat percentage through BIA and compared the results of three different ways, step by step analysis of the ratio between skin fold thickness and body fat, we have below conclusions.1. The body weight and other parameters of body composition become larger with the growth of the age between 30 and 54 years old. General group's body weight increase significantly, while fitness group's weight increase steadily, however, the different body compositions'have inconsistent changes. The body fat of both general group and fitness group increase steadily; the muscle content grows a lot during in fitness group,but not so much in general group.2. The body fat distribution becomes larger with the growth of the age between 30 and 54 years old. General group's body fat tend to body and leg, there is no tendency on fitness group. It is shows that long-time exercise could improve body fat distribution and prevent to obesity.3. Compared the results from different ways, we found that it is error to use foreign equations. Before establishing equation, besides the subjects of sex, age, race and other factors, we should made full consideration to their level of activity difference.4. Through this research a reliable and accurate formula comes out to assess general group and fitness group's body fat percentage with skin folds. The formula is as below.Fitness group: Fat%=26.369+0.312* Triceps-0.956*Iliac+0.511*Thigh (30-54 years old)General group: Fat%=12.576+0.301*Triceps+0.216*Belly+0.161*Scapular (30-54 years old)...
