The group of cyclists who didnt consume any fluids during their cycle experienced an increase in heart rate of 10%. At the beginning of exercise there is a depression of the PNS and stimulation of the SNS, which causes a rapid increase in heart rate. Bohr Shift Checkpoint 2 Arterio-venous oxygen difference (A-VO 2 diff).

A reduction in hydration results in a decrease in blood volume and pressure, which results in cells becoming more concentrated and the kidneys not functioning effectively (decreased filtration). At the start of light submaximal aerobic exercise lasting less than 10 minutes, cardiac output and stroke volume initially increase and both then plateau after only a couple of minutes and are maintained for the remainder of exercise.
