There are three factors that affect the jumping ability:
1, look at the body parts. Mainly looking at Achilles tendon, the sitting height index is higher than thigh, shoulder width (acromion width), iliac width (between two iliac crest points) and hip breadth (between greater trochanter points). When the X leg and the O leg jump to the ground, the force is scattered and will not be concentrated on the trunk.
2. race. Normal black people, after training or exercise, can reach more than 80-90. White people are much inferior to black people, mainly reflected in the word "stable", solid footwall, insufficient explosive power, and red muscle fibers. The jumping ability of yellow people is higher than that of white people and lower than that of black people.
3. Gender. In fact, women's upper limb strength is 40% ~ 60% weaker than men's, while lower limb strength is only 25% ~ 30% weaker than men's. Because of the huge difference between men and women, it is more appropriate to use relative weight (absolute strength/weight) or relative lean weight (absolute strength/lean weight) as the standard to evaluate muscle quality. When relative weight is used to express the strength of lower limbs, girls are still 5% ~ 15% weaker than boys.
