Intramuscular water movement during and after isometric muscle contraction: evaluation at different exercise intensities.

abstract：BACKGROUND:The heat-washout method is an objective method that measures cutaneous blood flow rate (BFR) in ml (100 g. min)(-1), previously found useful for measuring toe BFR in non-diabetic patients with claudication. AIM:The method is used for evaluating the presence of a veno-arteriolar reflex (VAR) in the forefoot ...
