load is greater than normal and is progressively increased as improvements in fitness occur. As the body becomes familiar with a particular level of training stress, it adapts to it and further training at this level fails to sufficiently stress the system. As theses adaptations occur, the improvements in fitness are clear and thus the improvement in performance is heightened. These adaptations are stroke volume, cardiac output, resting heart rate, oxygen uptake, lung capacity, haemoglobin levels, muscle

Whereas the heart provides the major force that causes blood to circulate, the circulatory system has five unique functions. 1. Carries blood. Blood vessels carry blood from the heart to almost all the body tissues and back to the heart. Blood circulates through the body, it delivers oxygen to hungry cells, tissues and organs. During exercise, the body’s demand for oxygen significantly increases, so the cardiovascular system’s oxygen-delivering function is crucial to keep the body safe. 2. Exchanges nutrients
