It is important to work out and stay in shape so that you can improve your life span. Exercising is one of the finest ways to avoid diseases but one has to be careful about the heart rate. The maximum heart rate defines the threshold which a person can reach. Going beyond the maximum permissible limit is a risk as it increases the possibilities of heart problems.
Is there a core factor which effects the heart rate? The answer to this question is yes. The maximum heart rate varies with the age of an individual. A person with age of 55 years would not have the same heart rate as someone who is 28 years. Thus, it can be said that age is a key factor in deciding the maximum allowed heart rate.
