Hi! My name is Kelly and I am preparing for the State Championship Cross Country Meet. I have been running everyday in order to train for the meet so my heart rate will not go up. Training also helps improve my lung capacity which can help improve my overall performance. Running can also help the respiratory system. The heart delivers oxygen to the muscles. The muscles work harder during exercise, like running, requiring the body to use more oxygen and therefore create more carbon dioxide. This increases the lung's oxygen capacity and strengthens the muscles of the lungs. Running also helps improve the digestive system. Regular exercise helps improve digestion and elimination. It slows down the system in order to conserve energy for the muscles.
