Effects of Supine Ergometer Exercise on Hemodynamics, Lower Extremity Muscle Activity, and Cardiac Load

Abstract

[Purpose] The purpose of this study was to determine the effects of different exercise limb positions on lower limb muscle activity, cardiac load and hemodynamics. [Participants and Methods] Seven healthy male adults performed seated ergometer exercise (Sit Ex) and supine ergometer exercise (Sup Ex) at moderate exercise intensity, and the hemodynamics during 10 minutes of steady-state exercise were measured and compared between the exercises. [Results] Leg blood flow velocity was significantly higher in the Sup Ex group. The double product was significantly lower in the Sup Ex group. There were no significant differences in lower limb muscle activity or subjective exercise intensity. [Conclusion] The results of this study suggest that supine ergometer exercise is a safe exercise therapy.
