Abstract

[Purpose] To compare physiological responses and shortness of breath when standing and sitting in the recovery process after submaximal exercise. [Participants and Methods] A submaximal exercise stress test was conducted for 12 healthy university students. Their systolic pressure level, heart rate, double product, oxygen uptake, respiratory minute and tidal volumes, respiratory rate, and shortness of breath were measured under 2 recovery conditions, sitting and standing, at 4 points: immediately and 3, 6, and 9 minutes after exercise. [Results] The systolic pressure level did not differ between the 2 postures, whereas the heart rate was higher throughout measurement, and the double product was also higher at 3 minutes after exercise under the standing recovery condition. The difference in the posture after exercise did not influence the other parameters. [Conclusion] The results suggest that in the recovery process after exercise, the heart rate compensates for an insufficient stroke volume to keep the circulating blood volume stable, and the level of stress to the heart at the early stage is higher when standing, but the oxygen debt repaid is similar, and there are no differences in the ventilatory parameters or shortness of breath between the 2 postures.
