Application of carbon dioxide to the skin and muscle oxygenation of human lower-limb muscle sites during cold water immersion.

ABSTRACT:

Background

Cold therapy has the disadvantage of inducing vasoconstriction in arterial and venous capillaries. The effects of carbon dioxide (CO₂) hot water depend mainly on not only cutaneous vasodilation but also muscle vasodilation. We examined the effects of artificial CO₂ cold water immersion (CCWI) on skin oxygenation and muscle oxygenation and the immersed skin temperature.

Subjects and methods

Fifteen healthy young males participated. CO₂-rich water containing CO₂ >1,150 ppm was prepared using a micro-bubble device. Each subject's single leg was immersed up to the knee in the CO₂-rich water (20 °C) for 15 min, followed by a 20-min recovery period. As a control study, a leg of the subject was immersed in cold tap-w
