Spearman rank correlation test results (1) There is a correlation between BMI and physical fitness r = -0.422, significance P value = 0.002 (2) There is a correlation r = -416 between body fat and physical fitness, Significance P value = 0.003 (3) There is a relationship between visceral fat and physical fitness of r = -400, with a significant P value of 0.004. The results of the analysis using multiple correlation UI with linear regression showed that BMI, body fat, and visceral fat had a simultaneous influence of R = 0.521(3) which is a moderate influence.
