鐵人三項運動員血壓、肺功能與力竭運動表現

本研究目的為探討鐵人三項運動員之血壓、肺功能與力竭運動表現，並評估肺功能與最大攝氧量之間的相關性。研究對象為年齡介於20～25歲的健康男性，分別為12名鐵人三項菁英運動員，與10名無規律運動習慣之受試者作為一般組，每位受試者必須進行休息和最大運動時血壓、靜態和動態肺功能與力竭運動表現之檢測。研究結果發現：血壓方面，鐵人三項組之休息時收縮壓明顯高於一般組，而休息時舒張壓及最大運動時之收縮壓和舒張壓於二組間皆無顯著差異。此外，二組之動脈硬化指數方面亦無明顯差異。肺功能檢測顯示鐵人三項組之潮氣量與用力肺活量皆明顯高於一般組，但其他肺功能指標於二組間無顯著差異。力竭運動表現方面，鐵人三項組之最大攝氧量與運動耗竭時間皆明顯高於一般組。最後以皮爾森相關性分析顯示，所有受試者之用力肺活量與最大攝氧量達顯著相關性。本研究結論為鐵人三項運動員之休息時收縮壓較高，但對動脈硬化指數無負面影響，且其用力肺活量亦顯著增加，整體而言，用力肺活量與最大攝氧量間存在顯著相關性。

This study aimed to investigate the changes in blood pressure, pulmonary function, and exhaustive exercise performance in triathletes. The relationship between pulmonary function and maximal oxygen consumption was also evaluated. Twelve male elite triathletes and ten non-athlete control subjects (aged 20-25 years old) were participated in this study. Resting and maximal blood pressure, static and dynamic pulmonary function, and exhaustive exercise performance were measured for all participants. Results indicated that resting systolic blood pressure (SBP) was significantly higher in the triathlete group compared with the control group. However, there were no significant differences in resting diastolic blood pressure (DBP) as well as maximal SBP and DBP between the groups. Moreover, the arterial stiffness index (ASI) showed no significant differences in both groups. The results of pulmonary function showed that the tidal volume and forced vital capacity (FVC) were significantly higher in the triathlete group. Additionally, the triathlete group had significantly higher maximal oxygen consumption (VO_(2max)) and longer time to exhaustion than the control group. Finally, Pearson correlation analysis showed that FVC was significantly correlated with VO_(2max) in all subjects. We conclude that the triathletes have higher resting SBP that have no negative influence on ASI, and have better FVC. In general, the FVC is significantly associated with VO_(2max) in all subjects.
