College Athletes: A Case Study

The dietary requirements of an athlete competing in the summer olympics will largely depend on the event they are taking part in and also the environment in which they are competing. An athlete who is competing in the decathlon event will need a high amount of blood glucose and full glycogen stores in the muscles and liver, to do this they will want to raise the intake of Carbohydrates (CHO) in preparation for the event and lower the intake of protein and fats. Previously, the belief with CHO loading was that there must be a 3-4 depletion phase, with high intensity training with low CHO intake, immediately followed by a loading period of 3-4 days with rest and a high CHO intake. However, today it is known that the depletion phase is not necessary, as 1-4 days of tapering the exercise and consuming a high CHO diet is sufficient in elevating muscle glycogen levels.

When planning the pre-event meal, the athlete must take into account that food consumed before exercise is only useful once it has been digested and absorbed. Also they must take into account the Glycemic Index, The glycemic index (GI) is a ranking of …show more content…

Mexico City is located at an altitude of 2500m above sea level, with an average temperature in the summer months of 32-37*C with 85% humidity. At this altitude the density of the air and ambient O2 content is considerably lower than at sea level, this reduced ambient O2 causes Arterial Hypoxia, meaning there is less oxygen in the blood. Arterial Hypoxia affects athletes performing intense Aerobic exercise severely as the lack of oxygen means that glycogen and fat metabolism for the re-synthesis of ATP is severely affected. For the athlete to be able to compete to the highest level in these environmental conditions they will need 3 weeks to acclimatize to the altitude, this time will allow for acclimatization to the heat and
