The rise in cardiac output is a result of a rise in heart rate and stroke volume and the subsequent plateau is a result of an appropriate supply of oxygen to sustain the metabolic demands of the physical activity. Cardiovascular drift, the progressive increase in heart rate and decrease in stroke volume that begins after approximately 10 min of prolonged moderate-intensity exercise, is associated with decreased maximal oxygen uptake, particularly during heat stress. AQA A Level PE specification. Flashcard Maker: Tom Grice. During exercise aim for 750-1500 ml of water per hour, depending on the weight of the individual, intensity of exercise and the conditions. A combination of an increased heart rate and blood viscosity puts greater strain on the heart, resulting in our heart working harder at a given intensity, potentially resulting in early fatigue. Including - The decrease in blood plasma results in a decrease in venous return, the volume of blood returning to the heart, and therefore a decrease in stroke volume, the volume of blood ejected from the left ventricle per beat.

Plain water is hypotonic, meaning it has a concentration lower than the blood. Functions of the cardiovascular system. 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. Cardiovascular physiologists suggest that cardiac drift is connected to an increase in core temperature and body water losses. It is therefore important that this fluid loss is replaced.

The gradual upward drift of heart rate is matched by a comparative reduction in stroke volume, which enables cardiac output to be preserved. PDF 815KB; Psychological factors affecting performance H555/02 - Sample question paper and mark scheme. Vascular shunting is regulated by the sympathetic nervous system, which controls blood flow through vasodilation (opening of the arterioles, increasing flow of blood into the capillaries) and vasoconstriction (constricting of the arterioles, decreasing the flow of blood into the capillaries). Source: Plowman, Smith; Exercise Physiology for Health, Fitness, and Performance. These figures will increase further if exercising intensely, particularly during endurance-based exercise or when exercising in warm temperatures. I like this article 806 8067 22 Happy training!
