Interval-induced metabolic perturbation determines tissue fluid shifts into skeletal muscle. When exercising for long periods of time or in warm temperatures, an increased loss of fluids through sweat, expiration and muscle contraction occurs. The rise in cardiac output is a result of a rise in heart rate and stroke volume and the subsequent plateau is a result of an appropriate supply of oxygen to sustain the metabolic demands of the physical activity.
