Long Jump Motion Analysis Based on the Aerodynamics

Abstract:

The long jump motion is a traditional track and field event. This sport is not only relevant with athletes congenital physical conditions, but also with the action skills in the long jump process. In the process of long jump, from the run-up to the take-off and landing, relatively large air resistance will be suffered, and the air resistance is affected by the size of the take-off speed and jumping height. Based on this, this article has carried on the detailed analysis of the air dynamic theory in the process of athletes long jump. It also has established the mathematical model of the friction resistance and air pressure resistance in the long jump process, and it has obtained the maximum incident angle when the maximum jump distance was happened by the take-off angle. Finally, through the experiment method, it has established the jumping speed loss curve and loss table under the air resistance effect, and obtained the incident angle and take-off speed in the long jump process, which provides the theory basis for the research of long jump motion.
