أثر ممارسة رياضة السباحة على السعة الحيوية للرئتين لدى طلبة معهد التربية البدنية و الرياضية

Abstract

This study aims to investigate the physiological impact of specialized swimming practice on lung vital capacity. The research compares three groups of students from the Institute of Physical Education and Sports: first-year students, third-year students specializing in volleyball, and third-year students specializing in swimming. A descriptive-analytical methodology was adopted, and a purposive sample of 36 male students was selected, equally divided into the three groups. Lung vital capacity was measured once for each participant using a spirometer, and the data were analyzed using the Student t-test.

The findings revealed statistically significant differences in lung vital capacity among the groups. The swimming group demonstrated the highest values, followed by the volleyball group, while the first-year group recorded the lowest. These results confirm the study’s main hypothesis and the sub -hypotheses, indicating that swimming is one of the most effective sports in enhancing respiratory function. This is due to its reliance on regulated breathing techniques and breath control underwater, which help strengthen respiratory muscles and improve lung elasticity.

The study concluded that integrating swimming-based training elements into physical education programs, even in non-aquatic sports, can significantly enhance respiratory efficiency. It further recommends conducting future studies on other physiological indicators and expanding the sample size to include different institutions, in order to generalize the results.
