What is meant by anticipatory rise?

Anticipatory rise refers to the increase in heart rate that occurs just before the start of physical activity. This physiological response is the body’s way of preparing for the demands of exercise. The heart rate begins to elevate as the central nervous system signals the body to prepare for action, which includes increased blood flow to the muscles and other tissues that will be engaged during the activity.

This response can happen even before any physical exercise begins and is characterized by the body’s readiness to meet the anticipated energy requirement. Factors that contribute to this response include the excitement of beginning the activity, the innate understanding of the physical demands of the exercise, and hormonal responses that prepare the body for vigorous activity.

In contrast, an increase in heart rate during exercise pertains to the body responding to the physical exertion rather than anticipation, while a decrease in heart rate before exercise would not align with the common physiological response that prepares the body for activity. Stabilization of heart rate during exercise is a different concept that refers to the body reaching a steady state where the heart rate levels off after initially rising, which does not apply to the anticipatory rise scenario.
