Intensity training became a popular concept in the mid-80s when heart rate monitors rapidly changed the approach to endurance sports. However, if dehydration occurs during exercise, we see a reduction in blood plasma, resulting in the thickening of blood and a decreased distribution of blood to the skin. At the beginning of exercise there is a depression of the PNS and stimulation of the SNS, which causes a rapid increase in heart rate. This compensation helps maintain a constant cardiac output .

Homeostasis is a mechanism employed by the body to maintain a relatively stable equilibrium. Hydration has many important functions for health, including the regulation of body temperature and blood pressure, cleaning the body and removing it of stored toxins, supporting immune function, aiding digestion and ensuring transportation of oxygen and nutrients around the body. The PNS is mainly responsible for managing homeostasis and SNS is mainly responsible for causing action, such as the fight or flight response. This increase lasts for the first 1 to 2 minutes of exercise, with the degree of increase relating to exercise intensity. 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.

Water is vital for life and ensuring adequate hydration is important for both physical and mental well-being and performance. 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 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. How can you use your heart rate to do basic endurance training? What term is used to describe a rise in heart rate despite working at a constant intensity?

The Student Room and The Uni Guide are both part of The Student Room Group. 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 . 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.

Engaging in moderate-to-vigorous intensity physical activity (MVPA) is important for protecting cardiovascular health among women in midlife (i.e., ages 40-60)-particularly if they have already developed conditions that increase their risk for cardiovascular disease (e.g., hypertension). jamesbrabin Teacher.
