Standing long jump refers to the long jump starting from a standing position without running up. 20 14 "national student's physical health standard" stipulates that standing long jump is a compulsory item in the annual physical fitness test of junior high school, senior high school and university.
Infrared non-contact automatic measurement of standing long jump distance reflects the explosive level of human lower limbs. According to the plan of the Ministry of Education, all test items such as standing long jump should be fully popularized with intelligent instruments, and equipped with data management software to provide exercise prescriptions.
Students' Standing Long Jump Technique
1. Preparation stage
At first, stand naturally, don't put your legs together, and keep your feet shoulder-width apart. Next, swing your hands forward and keep your legs straight. Then put your hands back as far as possible, lower your center of gravity and bend your knees.
2. Take-off phase
When taking off, both feet and soles of feet push the ground hard at the same time, and both arms swing upward hard, so that the whole person can jump forward and fully expand.
3. Trestle
Remember to tuck in your abdomen, stretch your calves forward and push your arms forward when you land. One thing we should remember is that if our hands touch the ground backwards when landing, then the jumping distance is calculated according to the ground position where our hands touch the ground.
