Comparison of respiratory muscle forces of young weightlifters with different branches

The purpose of the research; of this study is to compare the respiratory muscle strength parameters and aerobic fitness levels of weightlifters with athletes of different branches and individuals who do not do sports. A total of 72 male individuals between the ages of 12-14 who did weightlifting (n=13), wrestling (n=15), football (n=14), swimming (n=15) and who did not do sports as a control group (n=15) participated in the study. . Powerbreathe K5 device was used to determine the respiratory muscle strength levels of all participants in the study. Aerobic fitness levels were determined using the yo-yo intermittent recovery level 1 test. It was determined by the Shapiro-Wilk test that the data obtained at the end of the study consisted of normally distributed data. In the analyses, oneway anova test was used for multiple group comparisons, and Tukey test was used as a post hoc test to determine the difference levels of the groups. As a result of the analyses, when the characteristic features were examined, it was determined that there was no significant difference between the groups in age, height, body weight, body fat percentage (BF%), fat free mass (FFMI) values (p> 0,05). When the respiratory muscle strength parameters of the participants were examined, it was determined that the maximal inspiratory pressure, peak inspiratory flow and respiratory volumes of the weightlifters were significantly different compared to the football players, swimmers and the control group (p <0,05). It was determined that there was a significant difference in aerobic fitness levels between weightlifters and football players (p<0,05). As a result, it is seen that the respiratory muscle strength parameters of weightlifters are at high levels compared to other sports branches and the control group, but their aerobic fitness levels are at low levels. It is thought that the reason for this situation is that the respiratory muscle strength level increases due to the inhalation and exhalation practice in weightlifting training, but it does not contribute to the development of aerobic capacity because aerobic endurance is not emphasized in the training practices.
