Blood Pressure Changes During Exercise: What You Need to Know - Cardiology

Understanding blood pressure changes during exercise is crucial for assessing cardiovascular health and overall fitness. When you engage in physical activity, your body undergoes several physiological changes to accommodate the increased demand for oxygen and nutrients by the muscles. This includes alterations in heart rate, cardiac output, and blood pressure.

Initially, during exercise, systolic blood pressure (SBP) typically rises due to increased cardiac output. This is because your heart pumps more blood to supply the working muscles. However, diastolic blood pressure (DBP) may remain stable or even decrease slightly, especially during aerobic exercises. This phenomenon can be attributed to the vasodilation of blood vessels in the muscles, which reduces peripheral resistance.
In your case, you observed that your SBP increased slightly from 130 mmHg to 132 mmHg during exercise, while your DBP dropped from 83 mmHg to 73 mmHg. This is not unusual and can be explained by the fact that during exercise, your body prioritizes blood flow to the muscles, leading to a decrease in vascular resistance in those areas. The overall effect can sometimes result in a lower DBP post-exercise, which is a normal response.

After exercise, it is common for blood pressure to drop as your body begins to recover. The heart rate decreases, and blood vessels gradually constrict back to their resting state. This recovery phase can lead to lower blood pressure readings, which you noted when measuring at home, with a maximum of 115 mmHg and a minimum of 72 mmHg. These values indicate that your blood pressure is within a normal range, especially considering that the American Heart Association defines normal blood pressure as less than 120/80 mmHg.

It is essential to monitor your blood pressure regularly, especially if you have concerns about hypertension. Fluctuations in blood pressure readings can occur due to various factors, including stress, hydration levels, and even the time of day. If you consistently observe elevated readings, it may be worth consulting with a healthcare professional for further evaluation.

In summary, the changes in your blood pressure during and after exercise are typical physiological responses. A slight increase in SBP and a decrease in DBP during exercise can indicate that your cardiovascular system is functioning well. Your home readings suggest that you are not experiencing high blood pressure, but maintaining a healthy lifestyle, including regular exercise and a balanced diet, is essential for long-term cardiovascular health. If you have ongoing concerns or experience symptoms such as dizziness or chest discomfort, it is advisable to seek medical advice for a comprehensive assessment.
