cardiovascular drift a level pe

Cardiac drift can be defined as the upward drift of heart rate over time, coupled with a progressive decline in stroke volume and the continued maintenance of cardiac output. Provide an explanation for this phenomenon. At the start of moderate-intensity aerobic exercise lasting over 30 minutes, cardiac output also increases, but to a higher level compared to lighter, submaximal exercise. Med Sci Sports Exerc.

The ANS is split into two main parts, which are the. So when youre on the go for an extended period of time, there are, in this case, a few considerations. 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.
