Level 3 Level 5. 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. An increase in heart rate occurs due to the effects of dehydration. The increase in cardiac output is due to an increase in both heart rate and stroke volume. Mnomics Pleaaaaase help me .

Furthermore, when core body temperature increases the body responds by increasing skin blood flow to help control the temperature rise. Prolonged exercise induces cardiovascular drift, which is characterized by decreasing mean arterial pressure (MAP), stroke volume and heart rate increase. Hydration in the body is carefully controlled as allowing too much or too little water into the cells can have significant consequences. 2021 Oct 5;59(5):325-333. doi: 10.2486/indhealth.2021-0072.

Stroke volume, plasma volume and venous return. 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).

Although the exact mechanisms underlying cardiovascular drift are still unknown, two theories have been proposed. Cardiovascular drift (CVD, CV drift) is the phenomenon where some cardiovascular responses begin a time-dependent change, or "drift", after around 5-10 minutes of exercise in a warm or neutral environment 32 C (90 F)+ without an increase in workload. Cardiovascular diseases (CVDs) are the leading cause of death globally. To ensure quality for our reviews, only customers who have purchased this resource can review it.
