Body mass index is standard weight (kg) = height (cm)- 105. The actual weight is normal in the range of 10% of the standard weight calculated according to the formula, more than 20% is obese, 20%-30% is mildly obese, 30%-50% is moderately obese, and more than 50% is severely obese.
For example, a girl is 1.6 meters tall and weighs 50 kilograms. The standard weight is:
1, body mass index = 50/1.62 = 50/2.56 =19.53.
2. The body mass index is the standard weight (kg) = 160- 105 = 55.
The body mass index of male college students is 17.9 ~ 23.9.
The body mass index of female college students is 17.2 ~ 23.9.

Physical fitness test items:
1, sit forward, which is a physical health test item for universities, primary and secondary schools. The purpose of the test is to measure the possible range of motion of joints such as trunk, waist and hip at rest, which mainly reflects the development level of extensibility and elasticity of joints, ligaments and muscles in these parts and the flexibility of the body.
2. Body mass index mainly reflects the strength of human forearm and hand muscles, and is also related to the strength of other muscle groups, and it is also a good indicator to reflect the overall strength of muscles.
3. Standing long jump, that is, the long jump without run-up from a standing posture, is a sport that integrates jumping, explosive force, physical coordination, technology and other physical qualities. The National Student Physical Health Standard 20 14 stipulates that the standing long jump is a compulsory item in the annual physical fitness test of junior high schools, senior high schools and universities, and it has also become one of the important factors to measure students' physical fitness.
