Research on the Factors Influencing Long Jump

Long-jumpers’ performances are affected by various factors. Based on the physical characteristics, take-off angle, approach speed, air density of environment, etc., this paper establishes a mathematical model that can obtain the long-jumpers’ theoretical long jump performance. The conclusions are as follows: (1) Air resistance has almost no effect on the athlete's long jump performance. (2) The faster the approach speed leads to better results. (3) Theoretically, the take-off angle is proportional to the distance for long-jumpers cover, but high take-off angle will unbalance the body, resulting in a greater loss of speed, and reduce the performance. The model in this paper has very small errors and has good applicability. It is recommended that athletes increase the approach speed and increase the take-off angle on the premise of maintaining body balance.
