Text
Noninvasive determination of cardiac output (Q) and stroke volume (SV) based on the study by Stringer et al. [1] provides a simple and low-cost assessment of cardiac function in response to exercise. Based on our previous experience ([2]) we studied the estimated values of Qmax and SVmax in 4 groups af male subjects of different performance level. Group A (n=10) included young swimmers, group B (n=12) junior ice hockey players, group C (n=11) competitive cyclists and group D untrained university student volunteers (n=11). Data collected from the groups are summarized in Table 1 [Tab. 1] (anthropometric characteristics), Table 2 [Tab. 2] (cardio-rerspiratory parameters including Qmax and SVmax) and Table 3 [Tab. 3] (obtained data compared to Czech norms for average population based on IBP /International Biological Program/ results). The results showed significant differences in Qmax and SVmax between the groups in accordance with different athletic history of the subjects.
