The human cardiovascular system is responsible for delivering a continuous supply of oxygen and nutrients to active muscles, which maintains a high level of energy transfer, while also removing metabolites. A reduction in hydration results in a decrease in blood volume and pressure, which results in cells becoming more concentrated and the kidneys not functioning effectively (decreased filtration).

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). In the realization of photonic integrated devices, materials such as polymers are crucial. Variations between trained and untrained individuals. PDF 409KB; Physiological factors affecting performance H555/01 - Sample question paper and mark scheme. Level 3. As a result, our cardiac output decreases, the volume of blood ejected from the left ventricle in a minute, which coincides with a decreased oxygen delivery to the working muscles and subsequent reduction in performance. The reason for these claims is due to the loss of electrolytes (mainly sodium, or salt) in our sweat. . 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.Consequently, the increased heart rate reflects an increased relative metabolic intensity during prolonged exercise in the heat when . The fluid lost during exercise increases due to a rise in sweating, respiration and muscle contraction. INTRODUCTION "Cardiovascular drift" (CV drift) is a phenomenon whereby some CV responses begin a continuous time-dependent change, or "drift," after 10 min of prolonged moderate-intensity exercise (e.g., 50-75% Vo 2 max) in a neutral or warm environment ().As displayed in Figure 1A, it is characterized by a progressive decline in stroke volume (SV) and pulmonary and systemic . 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. A range of lessons based on A Level PE AQA - linked to the Cardiovascular system et al. PDF CHAPTER 1 THE CARDIOVASCULAR SYSTEM Practice questions - text book The Cardiovascular System Learning Content - The PE Classroom - Pupil Prolonged exercise induces cardiovascular drift, which is characterized by decreasing mean arterial pressure (MAP), stroke volume and heart rate increase.
