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 . Atria. Brings deoxygenated blood back to the Right Atrium. This is an up to date, all-inclusive Powerpoint designed to span 2-3 lessons on the AQA A Level PE course (2016 specification). Cardiac drift occurs while exercise intensity remains constant. The increase in skin blood flow occurs at the same time that the working muscles demand a large proportion of blood flow, which creates competition and demand from different parts of the body. 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.

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 . Atria. Brings deoxygenated blood back to the Right Atrium. This is an up to date, all-inclusive Powerpoint designed to span 2-3 lessons on the AQA A Level PE course (2016 specification). Cardiac drift occurs while exercise intensity remains constant. The increase in skin blood flow occurs at the same time that the working muscles demand a large proportion of blood flow, which creates competition and demand from different parts of the body. 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. Why cardiac drift is important for runners who train by heart rate PE AQA PHED 1 CARDIOVASCULAR SYSTEM. Answer Booklet.
