Effect of Light Load Exercise on Transcutaneous Oxygen Pressure in the Lower Extremities of Healthy Adults

Abstract

[Purpose] To clarify the effect of exercise therapy on the transcutaneous oxygen pressure (PtcO₂) in the periphery of the lower limbs. [Participants and Methods] Twenty healthy adults without cardiovascular disease were enrolled in this study. Exercise therapy was conducted under two conditions, resistance exercise (RE condition) and aerobic exercise (AE condition), and changes in the percutaneous partial pressure of oxygen were monitored under both conditions. [Results] In the AE condition, PtcO₂ during exercise was significantly lower than in the RE condition, but there was no significant correlation between changes in PtcO₂ and SpO₂ in the lower limbs in either condition. [Conclusion] It is possible to conduct single-joint resistance exercises without causing as large a decrease in PtcO₂ as in aerobic multi-joint exercises.
