Aspects Regarding the Impact of Respiratory Efficiency on Swimmer Performance

This paper aims to highlight the effect of endurance training on the development of the swimmers' performance, vital capacity, inspiratory muscle power, and inspiratory flow. The research was conducted on two directions: establishing the differences in lungcapacity, inspiratory power, and inspiratory flow in CmH2O between open water swimmers and indoor pool swimmers, and establishing the differences in lung capacity, inspiratory power, and inspiratory flow between swimmers in the 2nd - 4th places andswimmers in the 8th - 32nd places at the last national championships. The research methods used in this study were: the study of professional literature, the observation method, the experiment method, the statistical-mathematical method, and the graphicalrepresentation method. The Powerbreathe K series device was used to measure the efficiency of inspiratory muscles, recording the values of lung capacity, inspiratory flow and power, and output in CmH2O.
