The aim of the study was to compare a level of jump abilities of elite Slovak soccer players at different playingHpositions in field (n = 38, age = 23.4±4.9 years, height = 180.1±6.8 cm, weight = 76.8±7.0 kg; defenders = 15, age = 25.4±5.2 years, height = 181.2±5.0 cm, weight = 78.0±6.5 kg; midfielders = 16, age = 21.4±4.0 years, height = 176.8±6.4 cm, weight = 73.1±6.4 kg; forwards = 7, age = 23.4±4.4 years, height = 185.4±7.5 cm, weight = 81.7±7.7 kg). Jump abilities were measured on 2 types of vertical jumps with a device FiTROJumper, (FiTRONIC, Bratislava, Slovak Republic): Squat jump (SJ) and Countermovement jump (CMJ). The criterion of level evaluation of jump abilities was the height of jump in cm with accuracy 0.1 cm. The device One-way analysis of variance (ANOVA) was used for determination of difference significance (á = 0.05) between playing positions. The statistical analysis was realized by software IBM® SPSS® Statistics V19. Performance by defenders was observed with these values (SJ = 36.3±4.0 cm, CMJ = 37.3±4.4 cm), by midfielders (SJ = 37.1±4.4 cm, CMJ = 37.8±5.9 cm) and by forwards (SJ = 36.7±2.9 cm, CMJ = 37.8±3.6 cm). The statistical analysis did not show any significant differences between playing groups (Squat jump: F(2.35) = 0.164, p > 0.05, ç2 = 0.01; Countermovement jump: F(2.35) = 0.050, p > 0.05, ç2 = 0.003).
