Abstract

This study aimed to evaluate the effect of respiratory efficiency training on some physiological variables and swimming ability performance of young male swimmers. 17 young male swimmers participate in this study. They were randomly divided into three groups: a control group who did swimming training without breath restriction, and two experimental groups who did swimming training with chest wall restriction and Ultrabreath. All groups participated in a swimming program. They trained 4 times a week for a total of 6 weeks during which they swam at 70– 85% HR max every session. A Vo2max, breathing rate and heart rate were accounted to indicate physiological state. A Modified Balke tests, as well as T-20 test were used to measure time to exhaustion and swimming ability performance, respectively. One way ANOVA were used to analyse the data. The results showed improvement in independent variables in the experimental groups. There was no significant difference between the two experimental groups. Therefore, the results showed that using different means in order to impose more stress on respiratory muscles during exercise leads to some adaptations in these muscles, which may yield improvements in athletic performance.
