Abstract
- We undertook this study to determine whether long-term high intensity exercise would modify cutaneous endothelial-dependent vasodilation. We compared a group of 9 highly trained windsurfers (mean age: 24.5 +/- 1.6 years) to a control group of 8 sedentary individuals (22.9 +/- 0.4 years, NS). Laser Doppler was used to measure cutaneous blood flow in the resting state (baseline), during post-occlusive hyperaemia (endothelium-dependent vasodilation), and local heating to 42 degrees C. Lipid profile was similar in both groups. Resting heart rate was significantly lower in windsurfers. Baseline cutaneous vascular conductance (CVC) values were similar in both groups (0.059 +/- 0.016 and 0.051 +/- 0.009). During reactive hyperaemia, normalized peak CVC value was significantly higher in the windsurfers group (1775.4 +/- 286.9 and 826.4 +/- 121.7 % baseline CVC; p = 0.01). Normalized peak CVC value in response to local heating (42 degrees C) was not significantly different between both groups (2359.4 +/- 346.1 and 1467.7 +/- 282.6 % baseline CVC). Endothelium-dependent vasodilation in cutaneous microcirculation is significantly enhanced in the forearm skin of highly trained windsurfers when compared to sedentary controls.
