List three physiological adaptations that occur to improve exercise performance and state how or why improvement occurs.
1. Increased maximal blood flow - maximal stroke volume increases, which increases maximal cardiac output.
2. Increased oxygen delivery and carbon dioxide removal - Maximal breathing rate increases, along with a larger tidal volume, resulting in high pulmonary ventilations (and ability to remove carbon dioxide at a higher rate), better maintaining appropriate acid/base balance.
3. Increased maximal oxygen uptake and aerobic power - increase in number of capillaries per muscle fiber, providing richer supply of oxygen & nutrients, removes carbon dioxide & other wastes, allows higher maximal rate of aerobic energy production. Increased fuel storage.
