Sažetak
On the sample of 29 elite Croatian oarsmen we have measured the ventilatory and metabolic parameters by means of the open spiroergometric method during incremental exercise test on a rowing ergometer. The maximum ventilation ranged from 147 to 232 l/min, whereas the average maximum oxygen uptake amounted to 5.59 l/min, ie. 65.0 ml/kg* min, heart rate ranging from 175 to 211/min, and the oxygen pulse 26.3 to 34.3 ml O,/systole. High average figures of the respiratory quotient (RO = 1.12 ) and of the expirated carbon dioxide (VCO, = 6.26 I/min ) show both significant. participation of anaerobic energy sources, and the exhausting character of the test. At the anaerobic threshold (with the concentration of the lactic acid in blood of 4 mmol/L) the average oxygen uptake amounts to “OS + O44 I/min (86 +/- 3% VO₂max) at the workload of 305 +/- 28 W High values of aerobic capacity of Croatian oarsmen correspond to the results of elite oarsmen from other countries. This represents a good basis for further improvement of Croatian oarsmen if we take into consideration their youth (the average age is 20) and good training conditions.
