Exercise Physiology Of Ski Racing Essay - 1434 Words

Task 2: Exercise Physiology Ski racing is a sport where you race quickly down a ski slope around gates. There are short-term effects whilst performing the sport and long term from training. 1. Short Term Responses Cardiovascular Respiratory Muscular †¢ Heart rate increases †¢ Body temperature increase, particularly in the face. †¢ Respiration rate increases †¢ Muscle Pain Heart rate increase: During a race your muscles are contracting very frequently and working very hard, especially the leg muscles, this means a lot of oxygen and waste removal is required to keep the muscles working. Blood delivers oxygen to the muscles and helps to remove wastes such as lactic acid, during a race the heart rate increases to perform these tasks. This affects my sport as the increased heart rate allows muscles to contract more frequently and last longer without burning and feeling like ‘jelly’, by providing them with more oxygen and waste removal you can therefore work harder and perform to a higher level. Body temperature increase: For muscles to work at a high level and contract frequently they require energy, this energy is obtained by burning fuels in a chain of chemical reactions. Heat is a by-product of these reactions and they cause the body temperature to increase. Heat is released predominantly by blood vessels coming to the skins surface, particularly in the face; this is because much of the heat energy is carried away from the muscles by the blood.
