Presentation of the main exercise physiological characteristics of rowing athletes and their signifcance for health maintenance
Physical exercise generally improves the function of individual organ systems, thus having a preventve efect against chronic diseases. Due to the adaptve changes in regular physical actvity, there is a large diference in the performance of the cardio-respiratory system between trained and untrained individuals. The tool for determining physical ftness is the measurement of exercise physiological characteristcs. The aim of our work is to investgate the main load physiological characteristcs of a well-trained rowing group and to compare them with reference values in the literature. Partcipants were subjected to spiroergometric examinaton, thus obtaining a picture of the performance of their cardio-respiratory system. Then we compared the results with the reference values of other well-trained endurance athletes and untrained individuals. The means of the studied group and the means of the reference values of the well-trained endurance athletes were signifcantly higher com- pared to the values of the untrained persons for almost all load physiological characteristcs. In the case of minute ventlaton (VE) the re- sult measured in the rowing group was 152.3 ± 11.5 (L·min−1) signifcantly higher than in the untrained group (p = 0.002). Regarding the relative aerobic capacity (rVO2max), the result of the rowing group was 60.1 ± 6.9 (ml·kg−1·min−1) compared to the untrained (p = 0.004), but signifcantly lower compared to the reference value of the trained endurance athletes (p =0.042). The benefcial efects of physical activity on the body are signifcantly refected in theperformance indicators of the cardio-respiratory system. In additon to raising awareness of proper nutrition, emphasizing the importance of physical actvity should also be part of health promotion.
