Glycolytic energy system resynthesis WE ARE HERE Aerobic energy system resynthesis Energy continuums EPOC Energy systems . 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. Prolonged exercise induces cardiovascular drift, which is characterized by decreasing mean arterial pressure (MAP), stroke volume and heart rate increase. If we drink too much and become hypohydrated (overhydrated), our kidneys increase filtration rates to deal with the increased blood pressure, subsequently, aldosterone levels decrease, resulting in more water being extracted from the blood and deposited through urination. Please consult your physician before starting a new fitness program. Characterised by a progressive decrease in stroke volume and arterial blood pressure, with a progressive rise in heart rate after 10 minutes of exercise in a warm environment.
