Abstract

In sports, monitoring respiratory function indicators across different exercise intensity zones and at various time intervals is crucial for accurately evaluating the physiological impact of exercise on an athlete’s body and informing effective training and recovery strategies. This information is essential for tailoring individualized training programs, optimizing athletic performance, and reducing the risk of overtraining. Additionally, monitoring recovery dynamics enables precise assessment of an athlete’s recovery status, supporting informed decisions on training load adjustments and readiness for subsequent exercise sessions. The primary objective of this study is to examine the respiratory function recovery dynamics in Vietnamese athletes from four key sports, athletics, table tennis, shooting, and Pencak Silat following submaximal capacity exertion. By analysing sport-specific physiological responses and recovery patterns, the study aims to contribute valuable insights that can enhance training monitoring and optimize recovery strategies for high-performance athletes in Vietnam. This study recruited a total of 76 athletes, including 49 males and 27 females. All participants were in the professional training phase, classified at Level I or higher, and were actively training at the Sports Training and Competition Centre in Bac Ninh Province, Vietnam. Results revealed that athletes generally demonstrate superior respiratory function compared to non-athletes, primarily due to physiological adaptations resulting from consistent, structured training regimens. A comparison of the four sports examined in this study, athletics, table tennis, shooting, and Pencak Silat revealed distinct differences in respiratory function recovery dynamics before, during, and after submaximal exercise. Athletes from athletics and Pencak Silat exhibited more favourable recovery patterns compared to their counterparts in table tennis and shooting. The current findings align with previous research on respiratory recovery patterns surrounding submaximal exercise. Consistent with earlier studies, this investigation observed an initial stabilization or slight decline in respiratory rate during exercise, followed by a sharp increase immediately post-exertion, and a gradual return to baseline values during the recovery period.
