摘要：Several factors are affecting athlete s'performance.Maximal oxygen consumption (yθ2 max) is an important criterion in determining the physiological capacity in predominantly aerobic activities.The pulmonary system has an important function in the transport of oxygen from the atmospheric air to the hemoglobin in the erythrocytes.It is possible to evaluate the functional state of the pulmonary syste m by interpreting the pulmonary function test parameters.We tested 28 male physical education studen ts (age:21.5 ± 1.6 yrs,height:184.0 ± 7.0 cmt weight:78.5 ± 7.5 kg) on a bicycle ergometer according to a gradually increasing workload protocol to as se ss their VO2max scores.Spiroergometric analysis was continuously monitored.The pulmonary function tests were applied at rest Our purpose was to determine the correlations between VO2 max and the VO2 at the anaerobic threshold (at 4.0 mmol/l lactate level) and the pulmonary function parameters in question.The following pulmonary function parameters are used:vital capacity (VC),forced vital capacity (FVC)t forced expiratory volume in the fir st min (FEV1.0) and maximal ventilated volume in one min (Ve max).With the exception of the correlation between Ve max and VO2 max (r = 0.48,p < 0.01) statistical analysis revealed no other significant correlations,therefore it would not be very precise to a sses s aerobic performance according to the pulmonary fun ction parameters.
