Ventilatory and metabolic parameters of Croatian thriatlets (original) (raw)

2002

Abstract

ABSTRACT The aim of the study was to determine the physiological profile, ventilatory and metabolic parameters, of Croatian triathletes of national rank. 8 male triathletes (age = 23,6 ± 2,3 years, BW = 77,3 ± 5,9 kg, height = 184,7 ± 5,7 cm, body fat = 8,0 ± 3,8 %, FVC = 6,6 ± 0,7 l, FEV1 = 5,4 ± 0,3 l) were tested with a continuous, incremental exercise on the treadmill (1.5% inclination), with speed increments of 1 km/h every minute until exhaustion. The maximal oxygen uptake achieved was 63,2 ± 5,4 ml/kg/min, with maximal running speed (Vmax) of 18,4 ± 1,7 km/h; maximal heart rate (HRmax) was 188,1 ±1 bpm. The selected functional variables at the ventilatory anaerobic threshold (VT) were: VO2max/kg=50 ± 6 ml/kg/min, % VO2max/kg 79 ± 4 %, speed of running 13,5 ± 2.0 km/h, % Vmax 79 ± 4%. The functional profile of Croatian, in comparison with world-class1,2,3,5, triathletes showed lower values for all parameters. As in other endurance sports, these parameters for evaluation of the aerobic capacity are not the sole predictors of racing success. Although other factors are also important, these parameters play a decisive role for success in triathlon and in the selection of talent for the sport.
