1.1 Objective: The purpose of this study was to investigate oxygen uptake, acid-base balance and energy system contributions during and after short maximal running in adult (n = 8), adolescent (n = 8) and child (n = 8) male athletes.
1.2 Methods: The tests included a maximal time trial of 400 m, 350 m and 300 m for different age groups respectively and a VO2max running test on a 200 m indoor track. Capillary blood samples to analyse pH and lactate were taken before and after the time trial. Energy system contributions were estimated using the accumulated oxygen deficit (AOD) method.
1.3 Results: Peak oxygen uptake (VO2peak) during the time trial was the lowest in children (53.1 ± 4.6 ml/kg/min) compared to adolescents (59.9 ± 3.7 ml/kg/min, P < 0.01) and t... view more»
