n
v = number of significant variables used in the regression model or interaction between variables; 30-m CODS
1 = the final time in the 30-m COD
1 Sprinting test; 5-m bCODS¹ = the best time at 5 m in the 30CODS¹; CODS¹dec = the percent sprint decrement in 30CODS¹; 30-m CODS² = the final time in the 30CODS²; SBJ = distance of the Standing Broad Jump; r = Pearson correlation coefficient; r
2 = coefficient of determination; p = significance level.
