why does my heart rate not increase with exercise

During exercise, you will notice changes in your heart rate. Specific heart rate ranges based on the person's age, gender, exercise intensity and type and fitness level. A slow heart rate, called bradycardia if under 60 beats per minute, sometimes happens during exercise. Shortness of breath, dizziness, lightheadedness, fatigue and confusion may indicate a slow beat. Being a muscle, your heart gains strength from exercising just as your shoulders and biceps would. As you improve your level of fitness through regular cardiovascular exercise, your heart becomes more efficient and beats slower both during exercise and at rest. Heart defects can also cause a slow heart rate. The heart receives electrical impulses that make it beat.


Sometimes these impulses become blocked. When blocked, the heart rate slows down. Additionally, there may be a blocked artery or other congenital undiagnosed heart defect. If you suspect any of these, seek medical help. The thyroid plays a crucial role in the efficiency of the heart. When the thyroid does not make enough thyroid hormone, called hypothyroidism, individuals often experience a slower heart rate due to the weakening of the heart muscle. In situations of someone with underlying heart disease, this will be more obvious. Medications such as beta blockers do not allow the heart rate to increase above a certain level to prevent heart problems. Any antiarrythmic and blood pressure medications impact the heart rate as well.


Digoxin is used to help the heart beat more efficiently. This causes a slow heart rate that may not match your exercise intensity.
No. In fact, youвre doing everything right. As your body becomes more fit, it requires more effort to elevate to the same level. Why? Because your heart actually pushes more blood with each pump. В If you want to work harder to make your heart beat faster, itвs very easy. Just increase the speed or difficulty level of your exercise. If you walk or jog, go faster. You can also add a slight incline to the route to make it more challenging. With these few small changes you will immediately feel a difference. If youвre inside on a treadmill or other machine, do the same. For group fitness classes, try exaggerating your movements more.


When the teacher kicks, be sure to kick just a little higher than normal. When moving around the room, take bigger steps. Pretend youвre the teacher and hold your body upright with proper posture. All these things help you hike the heart rate just a little bit higher. If all else fails, use the surefire heart rate elevator: your legs. The muscles in the legsвactually the rear glutealsвare the largest muscles in the body. When you start using those muscles with, your heart rate will skyrocket. These muscles are the key to elevating your heart rate in all activities. They can help you easily push your working rate up a few beats per minute. Have a question for our Experts?
