Document Summary

In response to any form of movement, the body undergoes a multiple of adaptations. The key adaptations take place in heart and muscles: provide a comprehensive comparison of the heart adaptations to endurance training vs. heavy resistance training. The main heart adaptations are: heart increases in size, increasing cardiac output, stroke volume, heart rate and blood pressure. The muscular walls of the heart increase in thickness, particularly in the left ventricle. That provides a more powerful contraction and increases ventricular lling. The increase in size of the heart enables the left ventricle to stretch more and thus ll with more blood. The increase in muscle wall thickness also increases the contractility resulting in increased stroke volume at rest and during exercise, increasing blood supply to the body. Cardiac output increases signi cantly during maximal exercise effort due to the increase in sv. This results in greater oxygen supply, waste removal and hence improved endurance performance.
