Diseases of the cardiovascular system (including the heart) are the leading cause of death in the United States for both men and women. On the other hand, there are actions that one may do to cut down on their chances of acquiring heart disease. One of these stages is exercise, which, according to Dr. Frederick Basilico, the Physician in Chief of Medicine and Chief of Cardiology at NEBH, adds may enhance heart health, reverse some of the risk factors of heart disease, and help you maintain a healthy lifestyle.
Does Heart Rate Increase During Exercise?
Yes, heart rate does increase during exercise!
When we exercise, our body needs more energy to power our muscles. Our muscles get that energy from the food we eat, which is broken down into a molecule called glucose.
But to get the glucose to our muscles, we need to move it around our body in our blood. That’s where our heart comes in! Our heart is like a pump that pushes blood around our body.
When we exercise, our muscles need more blood (and therefore more glucose) to keep working. So our heart has to pump faster to move that blood around more quickly. This faster pumping is what we call an increase in heart rate.
In summary: when we exercise, our muscles need more blood and glucose, and our heart pumps faster to deliver that blood and glucose to our muscles.
Formula for Heart Rate Measurement During Exercise
There is even a simple formula to explain this:
Heart Rate = Cardiac Output (the amount of blood pumped by the heart per minute) x Heart Rate (the number of times the heart beats per minute)
During exercise, both cardiac output and heart rate increase. So the formula would be:
Heart Rate during exercise = Increased Cardiac Output x Increased Heart Rate
The increased cardiac output is due to the greater amount of blood the heart pumps with each beat, and the increased heart rate is due to the heart beating more frequently to supply more oxygen and energy to the working muscles.

What effect does exercise have on your heart?
The heart is a muscle that gets stronger with activity. When you exercise, your muscles help to circulate blood throughout the body, relieving the heart of part of the pressure and work. Pumping blood requires less effort, and the heart grows stronger with time.
When you start exercising, your heart will contract faster, and your circulation will rise, allowing oxygenated blood to reach your muscles faster. As the demand for blood rises, the heart will strive to fulfill it by raising both the heart rate and the power with which it contracts. The increase in oxygen delivery is due to two factors: your heart will have more beats per minute and a more strong contraction each time it beats, allowing it to pump more blood throughout the body.
What are some of the advantages?
The heart and blood vessels both benefit from regular exercise. These benefits include a lower resting heart rate, an enhanced capacity to take in deeper breaths, a lower resting blood pressure, an increase in the number of calories expended, which may assist with weight reduction, and a reduced chance of developing cardiovascular disease.
These advantages to cardiovascular health assist in regulating cholesterol, and regular exercise may improve HDL cholesterol, which is the “good” cholesterol. Losing weight, which can help bring your “bad” LDL cholesterol down, may be accomplished by diet and exercise. Because it elevates your heart rate and causes you to burn calories, exercise may make it easier for you to maintain a healthy weight.
Important measures in preserving a healthy heart include adhering to a diet that supports appropriate weight maintenance, avoiding foods that are heavy in fat, and incorporating regular physical exercise into one’s daily routine. In addition, maintaining a regular exercise routine might assist in maintaining normal blood pressure as well as blood flow.
What kind and how much exercise?
Even if engaging in physical exercise has never been a regular part of your schedule, you still need to begin somewhere. Aerobic workouts, which are beneficial to your heart, include activities such as walking, running, and swimming. At least thirty minutes worth of moderate activity, such as walking, should be performed five days each week. Alternately, you might engage in moderate physical activity for at least half an hour, three times each week, such as jogging or cycling.
Before beginning any new fitness regimen, you should arrange an appointment with your primary care physician to see whether or not doing so is safe for you.
Is Increasing Heart Rate During Exercise Bad for Health?
During exercise, the heart rate increases to supply more oxygen and nutrients to the working muscles. This helps improve cardiovascular fitness and can lead to many health benefits, including:
- Lowering blood pressure
- Improving cholesterol levels
- Reducing the risk of heart disease
- Boosting mood and mental health
- Strengthening bones and muscles
However, it’s important to note that there may be some risks associated with exercising at high intensities or for prolonged periods of time, especially if you have pre-existing medical conditions or are new to exercise. It’s always a good idea to consult with a healthcare professional before starting a new exercise program, especially if you have any concerns about your heart health.
