Sports drinks often claim to be isotonic. INTRODUCTION "Cardiovascular drift" (CV drift) is a phenomenon whereby some CV responses begin a continuous time-dependent change, or "drift," after 10 min of prolonged moderate-intensity exercise (e.g., 50-75% Vo 2 max) in a neutral or warm environment ().As displayed in Figure 1A, it is characterized by a progressive decline in stroke volume (SV) and pulmonary and systemic . Water is also used in the contractions of muscle tissues, stored glycogen is used by the muscle cells for contraction.

What increases during cardiovascular drift? More oxygen extraction by blood to the muscles, Venous blood has less O2 so the is more diffusion at the lungs. The gradual time-dependent "drift" in several cardiovascular responses, most notably decreased stroke volume (with concomitant heart rate increase), during prolonged steady-rate exercise.

The increase in skin blood flow occurs at the same time that the working muscles demand a large proportion of blood flow, which creates competition and demand from different parts of the body. Your Polar heart rate monitor can be an invaluable tool during training and competition.
