The long jump comprehensive strength influential factor analysis based on PCA

PengCheng Li

This paper aims at the problems that long jump performance is more volatile and it is difficult to quantify the overall strength of athletes, uses mathematical tools to establish a scientific and reasonable long jump comprehensive strength evaluation index system. It uses the Principal Component Analysis (PCA) method to find the main factors, analyzes the results combining with expert advice, jointly determines the AHP weight of each index, thereby establishes the long jump comprehensive strength evaluation system model; through empirical testing, the results are scientific and rational, and can effectively solve the overall strength quantization problem of long jump athleteÂ’s.
