Spiroveloergometry parameters and parameters of blood gases and acid-base equilibrium at rest and during exercise in athletes]

The aim of the study was to evaluate spiroveloergometric and blood gases data and compare them among swimmers and basketball players. Examinations were performed for swimmers and basketball players (n=85). Spirometry at rest and spiroveloergometry, analysis of blood gases and acid-base equilibrium at rest and during exercise were performed. Minute ventiliation of swimmers at rest was statistically significantly (p<0.001) lower than of basketball players: 11.0 l/min and 22.1 l/min correspondingly. Partial pressure of blood carbon dioxide for swimmers was larger, than of basketball players (41.5 and 35.9 mm Hg correspondingly, p<0.001), plasma bicarbonates as well (25.2 and 22.5 mmol/l, p<0.01) and there was no bases excess (BE -0.22 and -2.95, p<0.001). Spiroveloergometry showed, that at the same minute ventiliation and the same work level oxygen metabolic units (MET) were significantly (p<0.001) larger for swimmers: 21.2 and 14.9 correspondingly. Decompensated metabolic acidosis during maximal exercise for swimmers was not determined.swimmers' ventilation was more economic than of basketball players, oxygen consumption and aerobic capacity were statistically significantly better.
