After an aerobic session, what is the acceptable increase in systolic blood pressure and heart rate compared to resting levels?

The increase in systolic blood pressure and heart rate following an aerobic session reflects the body’s physiological response to exercise. A typical and acceptable increase is associated with the intense demands placed on the cardiovascular system during physical activity, particularly for older adults or those undergoing rehabilitation.

In this context, an increase of 9 mmHg in systolic blood pressure and 5 beats per minute in heart rate is considered a moderate and safe response to aerobic activity. This level of change indicates that the cardiovascular system is efficiently accommodating the increased oxygen demand during exercise without excessive strain, making it suitable for most individuals, particularly in a geriatric population where safety is a high priority.

Higher increases in blood pressure and heart rate, found in the other options, might suggest overexertion or indicate an inefficient cardiovascular response to exercise. Such excessive changes can be concerning, especially for older adults who may already be at risk for cardiovascular conditions. Hence, the correct response reflects a balance between an appropriate exercise challenge and the health and safety of the individual participating in the session.
