概要	We hypothesized that carbonated water immersion increases muscle blood flow. To test this hypothesis, 10 men underwent lower leg immersion in tap or carbonated water at 38°C. We evaluated gastrocnemius muscle hemodynamics using near-infrared spectroscopy, skin blood flow by laser Doppler flowmetry, and popliteal artery (PA) blood flow by duplex ultrasound. Immersion in carbonated, but not tap water elevated PA and skin blood flow. The change in PA blood flow in response to immersion in carbonated water correlated with those of skin blood flow but not oxyhemoglobin concentration and tissue oxygenation index while no relations was found for tap water immersion. These findings indicate that water carbonation has minimal effect on muscle blood flow.
