Differences in respirogram phase between taekwondo poomsae athletes and nonathletes

Abstract

[Purpose] Respiratory physiotherapy is an effective approach to improving lung function in patient, including athletes with respiratory dysfunction caused by sports injury. The purpose of this study was to analyze the differences in the respirograms between taekwondo poomsae athletes and nonathletes according to the respirogram phase. [Subjects and Methods] Respiratory measurements for 13 elite taekwondo poomsae athletes were obtained. Respiratory function was measured using spirometry while the participant was seated. [Results] In respirogram phasic analysis, the inspiratory area of forced vital capacity were significantly increased in the athletes than in the nonathletes. The slopes of the forced vital capacity for athletes at slopes 1, 2, and 3 of the A area were significantly higher than those for the nonathletes. In correlation analysis, chest circumference was significantly correlated with slope 1 of the A area of the forced vital capacity. [Conclusion] Results indicate that differences in respirogram phasic changes between athletes and nonathletes may contribute to better understanding of respiratory function, which is important to sports physiotherapy research.

Differences in FVC and respirogram phase between the TKDP athletes and nonathletes. Area and slope of the FVC and respiratory parameters were determined, as described in the Subjects and Methods section. FVC: forced vital capacity; AS1–3: first, second, and third slopes of the A area; BS1–3: first, second, and third slopes of the B area; CS1–3: first, second, and third slopes of the C area; DS1–3: first, second, and third slopes of the D area; ExA: expiratory area; InsA: inspiratory area; TKDP athletes: taekwondo poomsae athletes
