College Students’ Body Composition And Constitution Related Analysis And Improve The Mechanism Research

With the rapid development of China’s economic level, people’s diet conditions and the rapid transformation of the structure, the imbalance of body composition (weight loss, overweight, obese) became the focus of attention. The correlation study of body composition and physical fitness, the understanding of college students lean body mass, body fat than to improve the students’physical fitness with the relationship between the physical and the body composition perspective has important implications.Used literature data, measurements, mathematical statistics and logical analysis, research methods for a sophomore242students (boys122Ming girls120Ming) carried the body composition, height, weight, grip strength, lung capacity, stairs, standing long jump, sit and reach, reaction time measurement and analysis of the indicators.The results:(1) bioelectrical impedance measurement of body composition is one of the existing measurement techniques most suitable for the individual body composition dynamic monitoring and large-scale population studies.(2) body fat ratio and BMI method in the overall evaluation of boys and girls, fat, thin type and individual, there are some differences.(3) boys and girls linear relationship exists in varying degrees in the four indicators of lean body mass, height, weight, lung capacity and grip strength, the boys lean body mass and physical stronger than girls, girls body fat than strong and physical than boys.(4) Physique total score and body composition of male and female students are not there is a correlation.(5) the optimal model of lean body mass and body mass of20to24-year-old female college student multiple regression equation:y=-11.522+0.384X1+0.194X2; ordinary20to24-year-old male college student in lean body mass and physical fitness is the optimal model equation for multiple regression:y=-22.905+0.412X1+0.287X2.Recommendations for the results:(1) from the angle of body composition, fat, thin proportions and physiological differences between men and women, boys should be increased lean body mass content focused on girls should focus on in order to reduce the proportion of fat.(2)Reasonable intake diet, strength training and aerobic exercise combined mode to increase the body’s lean body mass and reduce body fat ratio.(3) the relevant research institutions to strengthen the bioelectrical impedance technology to increase the measurement accuracy of the instrument, and gradually reduce production costs.(4) The relevant departments of the bioelectrical impedance method to establish suitable for different region, race, age, occupation and other characteristics of body fat than the norm.(5) College women’s3000m and men’s5000m as a physical examination of college students will test the project throughout the entire process of the entire university.
