有酸素機能からみた水泳及び陸上種目経験者の特徴

抄録

The purpose of this study was to compare the aerobic capacity during swimming and running from the view point of maximal oxygen uptake (VO₂max) and anaerobic threshold (AnT). Fifteen subjects (9 swimmers and 6 field athletes) performed progressive exercises until exhaustion by use of a treadmill and an experimental swimming pool. Respiratory responses were measurered using a computerized breath-by-breath test system for the determination of AnT and VO₂max, and the time points where they occurred. The results were as follows ; (1) Between the two exercises, there were significant differences in fractional concentrations of end-tidal O₂ (FETO₂), CO₂ (FETCO₂) and pulmonary ventilation (VE) at the two time points. (2) On the interaction of two exercises and two exercise groups, there were significant differences in FETO₂ and FETCO₂ at the two time points, and in oxygen uptake (VO₂) and VO₂/wt at the AnT.
