The following are common symptoms: Cardiovascular drift refers to an increase in heart rate during prolonged endurance-based exercise, despite working at a constant intensity.

I have found over many years of teaching PE and sport courses for GCSE, A-level, BTEC, VCERT, Cambridge National and Cambridge Technical that students need significant guidance on forming good quality practical examples (normally for AO2).The aim of this post is to set a standard for how practical examples should be structured to give the maximum opportunity to achieve marks in examined or . More energy is needed to cool body/sweat. 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. SV dependant on VR as one increase so does other, -Muscle pump veins situated between skeletal muscles contract forcing blood back.

The body controls its water level through the 'Renin angiotensin aldosterone system'. For example, a 60 kg individual, 60 divided by 0.024 = 2,500 l. 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. Useful information to help you with the course. 10) Explain what is meant by the term 'cardiovascular drift'. the maximum amount of oxygen the body can take in and use during exercise. What causes cardiovascular drift? Why cardiac drift is important for runners who train by heart rate These cookies help provide information on metrics the number of visitors, bounce rate, traffic source, etc. During exercise, vasodilation of the arterioles supplying the working muscles, skin,and heart occurs, increasing the supply of oxygen and nutrients.
