*
Significantly different from normotensive,
#
significantly different from before training. Blood pressures are home measurements in supine position (Omron M6 comfort, Kyoto, Japan). Femoral arterial blood flow and diameter were obtained after catheterization, but before the beginning of the experimental protocol.
