Bodybuilding - About your Heart
Bodybuilders train their
muscles, but they often neglect the most important muscle of them all - the
heart. Your heart is a great indicator of your level of fitness. Training your
heart can improve all aspects of your health. Your heart can even be used as a
guide to help improve your training and, more importantly, customize training to
your body. When you understand how the heart works and how it can be used as an
amazing tool for training, you will appreciate exactly how much the heart
matters!
Your heart is between one to two times the size of your clenched fist. Contrary to popular belief, it is not located to one side of the body - it is located almost in the exact center of your chest. Due to the shape of the heart and chest cavity, the heart pounds against the chest wall on your left side, so the heart rate is stronger when felt there. Your heart is responsible for pumping about six quarts of blood throughout your body, with about the same amount of force that the average person applies when squeezing a tennis ball.
The heart is not under voluntary control. A system known as the autonomic nervous system, which includes the sympathetic and parasympathetic nervous system, is responsible for regulating your heart rate.
There are many ways to measure how healthy a heart is. A healthy heart should beat with a fairly regular rhythm that will change based on levels of exertion and oxygen requirements. A healthy heart has a high stroke volume, which refers to the amount of blood that is pumped out with each beat. A healthy heart does not have to work as hard to pump blood, so the resting heart rate of a healthy heart will be lower than average. Blood pressure is another indicator of heart health and should be in the healthy range of around 120 over 80, as determined by the national average.
Various types of training have different effects on the heart. Training that elevates the heart rate for even brief durations can increase the size of the heart. This will increase the stroke volume, and result in a lower resting heart rate. Training can also increase the rate at which the heart recovers from a bout of intense work. In other words, a trained individual will return to their resting heart rate faster than a sedentary individual. Exercise has been shown to lower blood pressure. In addition, regular cardiovascular exercise can increase the concentration of hemoglobin in blood, allowing the body to become more efficient at transporting oxygen to the cells that need it (as well as removing waste products such as carbon dioxide).
