Respiration increases during exercise to meet the oxygen demand of the working muscles, resulting in a rise in water vapour loss through breathing, whilst sweat is lost in order to maintain body temperature. This results in the hormone, angiotensin II being released, causing vasoconstriction, therefore increasing blood pressure and sodium uptake, along with increasing aldosterone hormone release, causing a rise in the uptake of water in the kidneys. After 30 minutes of running, cardiac drift may cause your heart rate to increase so that you have to slow down to maintain that heart rate window of 160-170 bpm.

Intensity training became a popular concept in the mid-80s when heart rate monitors rapidly changed the approach to endurance sports. To understand the importance of fluid losses on cardiac drift researchers looked at cyclists who cycled for 2 hours either with or without taking on extra fluids during exercise. The fluid lost during exercise increases due to a rise in sweating, respiration and muscle contraction. These figures will increase further if exercising intensely, particularly during endurance-based exercise or when exercising in warm temperatures.

The study concluded that half the cardiovascular drift experienced by the cyclists could be explained by dehydration. Consequently, the increased heart rate reflects an increased relative metabolic intensity during prolonged exercise in the heat when cardiovascular drift occurs, which has implications for exercise prescription.

As moderate-intensity exercise continues passed the 30-minute mark stroke volume gradually decreases, although remains above resting levels. Cardiovascular drift during heat stress: implications for exercise Cardiovascular drift (CVD, CV drift) is the phenomenon where some cardiovascular responses begin a time-dependent change, or "drift", after around 5-10 minutes of exercise in a warm or neutral environment 32 C (90 F)+ without an increase in workload.

Is the transport of blood back to heart. The human body is largely made up of water, this ranges from approximately 60 % of an adult to up to 75 % in babies. A. A lack of blood at the skin decreases the sweating response, which in turn causes an increase in body temperature which if not lowered, in extreme cases can lead to heatstroke. When the group of cyclists who were able to consume enough fluids to match sweat rate completed their cycle their heart rate increased by only 5%. Level 3 Level 5.
