30S = 30-m Sprint test; 5-m vSprint = peak sprint speed for each 5 m in the 30S; 30CODS¹ = 30-m COD¹ Sprinting test; 30-m CODS¹ = the final time in the 30CODS¹; 5-m bCODS¹ = the best time at 5-m in the 30CODS¹; CODS¹dec = the percent sprint decrement in the 30CODS¹; 30CODS² = 30-m Backward and Forward Sprint Test; 10-m CODS² = 10-m starting speed time in the 30CODS²; 30-m CODS² = the final time in the 30CODS²; F&BCOD = time of COD from forward movement to backward movement (10-m distance) in the 30CODS²; B&FCOD = time of COD from backward movement to forward movement (10-m distance) in the 30CODS²; CMJ = height of the countermovement jump; SBJ = distance of the standing broad jump. The values are expressed as mean and standard deviation (SD) with 95% confidence interval (95% CI) and terms of coefficient of variation (% CV)
