Multiple linear regression analysis was calculated to predict the percentage of change in fitness levels a RASTmin. b RASTpeak. c RASTave and d Fatiguein based on accumulated workloads and PHV in the football players. Also. residual plot was calculated to predict the percentage of change in e RASTmin. f RASTpeak. g RASTave and h Fatiguein levels; the difference between the actual value of the dependent variable and the value predicted by the residual provided. PHV = Peak height velocity RASTmin: RAST minimum; RASTave: RAST average; Fatiguein: Fatigue index
