Popis výsledku v původním jazyce

Purpose. the aim 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. the total of 18 elite male soccer players (age: 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 f lexors and exten- sors strength, and intermittent anaerobic test on a bicycle ergometer (IAn tb E10x6s with a 30-s rest interval). t he strength and power outcomes of laboratory tests served as possible predictors of sprint performance in multiple regression analyses. Results. the correlation analyses showed 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 IAn tb E10x6s ( r value: from -0.47 to -0.55). t he average power measured by IAn tb E10x6s was associated with sprint lengths of 10, 15, and 20 m ( r value: from -0.45 to -0.49). t he SqJ predicted the 5-m sprint ( R = 0.48; R 2 = 0.18) and 10-m sprint ( R = 0.55; R 2 = 0.26). the PP together with the relative force (RF) predicted the 15-m ( R = 0.65; R 2 = 0.51) and 20-m ( R = 0.77; R 2 = 0.64) sprint performance. Conclusions. the RF in SqJ can be used as a parameter relevant to linear 5-m, 10-m, 15-m, and 20-m sprint. t ogether with PP, it can be applied as a parameter relevant to linear 15-m and 20-m sprint.
