Even if you are not a professional athlete, it is very helpful to know what causes accelerated heart rate (or pulse) and when it is not normal, and the risk involved. A normal heart rate is a very individual thing. It will vary from person to person. The only way to know what your ‘normal’ is by taking it at various times from resting, exercise and what you feel may be in your max heart rate.
Cardiovascular exercise is defined by getting your heart rate to 40% to 85% of your resting heart rate. A normal resting heart rate will vary from 60 to 100 beats per minute. How cardiovascular exercise works is when you are walking or running. Blood is restricted to pumping to those areas. Once you work harder, pumping your arms to get a more intense workout, your heart rate increases.
Once the heart registers the increased activity, the left ventricle of the heart adapts to the exercise and enlarges. Over time, your body will get used to activity, even high intensity activity, and your heart rate will lower. This causes a much lower calorie burns over all; however, also means your heart is healthy.
Increased heart rate also can produce stress. We all know too much daily stress releases a hormone than leads to belly fat. It is vital you are careful not to over train because over training over time, can over produce the belly fat making hormone as well. There is a fine line between over training and exercising enough to sustain weight loss and heart health.
Risk of high heart rate
Research has found that in extremely fit people, too high of a heart rate can be a risk factor for illness. Experts caution it is dangerous to allow your heart rate to go above 85% of your maximum heart rate. Fat burn mode is around 70% the maximum heart rate for most people. The main symptoms of a high heart rate are faintness, lightheaded, or dizziness. You will know if your heart rate is too high, it will be extremely uncomfortable. It is very common for your heart rate to be in the maximum, or above for a very brief time when running. This type of exercise is called interval training. Typically, you would sprint hard for only 20 minutes or a little longer, and then walk for a few minutes. This allows your heart to get a break, yet get the benefits of a high heart rate, as well.
It is not very common to see a high heart rate and high blood pressure. Usually, you will find the opposite: Low blood pressure and high heart rate. If you find high heart rate and low blood pressure, medical experts warn it should always be investigated to rule our cardiac heart complications. It could be normal, too, but as the saying goes better safe than sorry.
Exercise causes high heart rate, which I necessary for a healthy heart. You just have to be careful not to exert your heart too much over the 85% of the max rate. If you notice low blood pressure and high heart rate, see medical attention immediately. The basic rule is if you feel very uncomfortable, you should stop and rest to see if rests helps you feel better and return your heart rate to normal.
