| Popis: | PURPOSE The purpose of this study was to determine all different energy systems contribution during the maximal sprint cycling in youth cyclists. METHODS Fifteen male and female youth cyclists participated in this study. A simulated maximal 10 sec maximal sprint cycling was carried out. During maximal sprint cycling, energy contribution (phosphagen, WPCR; glycolytic, WLa -; oxidative system WOXI in kJ and %), maximal lactate production rate (VLamax), difference of lactate (ΔLa-), highest lactate (Peak La-), peak power (Wpeak) and anaerobicalactic time (tAlac) were analyzed using off VO2 kinetics, trapezoidal method, O2-lactate equivalent, and caloric quotient. RESULTS During the maximal sprint cycling, WPCR was significantly higher than WLa - and WOXI (p=.008; d: 0.98, p |
