When exercising, fluid demands would increase and the characteristics of the individual must be considered, such as how much they sweat or how heavy they breathe. 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. government site. As shown in the below graphs heart rate then plateaus and is maintained at that level during lighter intensity exercise, whereas with higher intensity exercise heart rate plateaus after the initial increase and then gradually increases or drifts in an upwards direction. Level 3 Level 5. The cardiovascular system has four main functions: deliver oxygen and nutrients to the body; remove the waste products such as carbon dioxide and lactic acid Hydration in the body is carefully controlled as allowing too much or too little water into the cells can have significant consequences.
