The relative force in squat jump is the best laboratory predictor of sprint performance in adolescent soccer players

Original language description

Purpose. The aim of this study was to determine the relationships between linear sprint performance and different outcomes relating to isokinetic strength, jump performance and intermittent Wingate test performance in well-trained young (U19) soccer players. Methods. Eighteen elite male soccer players (17.6 ± 0.8 years; body mass: 73.3 ± 5.9 kg, height: 180.8 ± 4.8 cm) performed a 20 m sprint test, countermovement jump, squat jump (SqJ), isokinetic measurement of knee flexors and extensors strength, and intermittent anaerobic test on a bicycle ergometer (IAnTBE10x6s with a 30 s rest interval). The strength and power outcomes of laboratory tests were used as possible predictors of sprint performance in multiple regression analyses. Results. The correlation analyses show a significant relationship between all sprint lengths and relative maximum force measured by SqJ (r value from -0.48 to -0.67), and between all sprint lengths and peak power (PP) measured by IAnTBE10x6s (r value from -0.47 to -0.55). The average power measured by IAnTBE10x6s was associated with sprint lengths of 10, 15 and 20 m (r value from -0.45 to -0.49). The SqJ predicted the 5m sprint (R = 0.48, R2 = 0.18) and 10 m sprint (R = 0.55, R2 = 0.26). The peak power measured by AnWT10x6 together with the relative force measured by SqJ predicted the 15 m (R = 0.65 R2 = 0.51) and 20 m (R = 0.77, R2 = 0.64) sprint performance. Conclusions. The relative force in SqJ can be used as a parameter relevant to linear 5m, 10m, 15m and 20m sprint. The relative force in SqJ together with PP at IAnTBE10x6 can be used as a parameter relevant to linear 15 m and 20 m sprint.
