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. Approximately how much water is lost through breathing every day? 3 marks Answer: Cardiovascular drift is characterised by a decrease in stroke volume and a parallel increase in heart rate to maintain a constant cardiac output. 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 When exercising for long periods of time or in warm temperatures, an increased loss of fluids through sweat, expiration and muscle contraction occurs. Maximal oxygen uptake after attenuation of cardiovascular drift during heat stress. (3rd year med) , Physical education OCR 24th may 2016 AS CREATE UNOFFICAL MARK SCHEME , A&P level 3. Cardiac drift can be defined as the upward drift of heart rate over time, coupled with a progressive decline in stroke volume and the continued maintenance of cardiac output. 582 Cards -. Throughout the day, we lose approximately 700 ml of water during expiration when breathing, 1.5 litres through urination and up to 150-200 ml as sweat whilst exercising.
