Sažetak
Forty-eight national level male runners: ten sprinters (S) (184.9 4.8 cm, 76.6 4.8 kg), personal best (PB) on 100m sprint = 10.87 0.41s ; fifteen 400m (S4)( 180.9 4.2 cm, 73.0 6.3 kg), PB on 400m 49.5 1.9s ; ten middle distance (MD) (180.4 5.7 cm, 68.6 6.2 kg) and thirteen long distance (LD) (n=13 ; 179.1 6.7 cm, 69.5 7.0 kg ) runners participated in the study. All subjects performed two incremental treadmill tests: the first (1 km/h speed increase per minute, 1.5% grade), for determination of VO2max and the anaerobic ventilatory threshold (AnT, respiratory compensation point according to Wasserman), and a second one (2 km/h speed increase every 4 minutes, 1.5% grade) to determine running economy for the speeed range below the ventilatory anaerobic threshold. With increasing length of track covered for a given running event, a progressive increase of aerobic capacity as well as increase of running economy was found. The groups differed significantly regarding both VO2max (55.4 ± ; 3.4 ; 59.6 ± ; 4.6 ; 64.4 ± ; 4.4 and 66.4 ± ; 4.7 ml/kg• min-1, p<0.01) and AnT (48.8 ± ; 2.4 ; 51.5 ± ; 3.9 ; 55.9 ± ; 4.3 and 59.0 ± ; 4.8 ml/kg• min-1, p<0.01), for S, S4, MD and LD, respectively. Significant differences between groups were also found for running economy at velocities below AnT (C8, metabolic cost at 8 kmh-1 – 0.217 ± ; 0.02 ; 0.212 ± ; 0.03 ; 0.208 ± ; 0.02 and 0.195 ± ; 0.01 ml/kg• m-1, p<0.05 ; C10 – 0.215 ± ; 0.01 ; 0.210 ± ; 0.02 ; 0.203 ± ; 0.02 and 0.191 ± ; 0.02 ml/kg• m-1, p<0.01 ; C12 – 0.211 ± ; 0.01 ; 0.208 ± ; 0.02 ; 0.198 ± ; 0.01 and 0.188 ± ; 0.01 ml/kg• m-1, p<0.01 ; for S, S4, MD and LD, respectively). The increase of running economy with increasing running speed was also significant, within each single group of runners (C8 > C10 > C12, p<0.05).
