Introduction An athlete needs to ensure that they consume enough fuel to complete activities undertaken. The amount of energy required depends on many factors including size and weight of the athlete, level and intensity of the training, and due to this the amount of energy required varies from person to person. However if more energy is consumed than required, the excess is stored as fat and weight will increase, on the other hand if insufficient energy is consumed the body calls upon its stores to meet the demand and weight will be lost. To consume a balanced diet we need to consume items from the macro and micro nutrient groups. Macronutrients comprise of carbohydrates, lipids and protein. Carbohydrates are quickly accessible and…show more content…
Female Tennis Player The athletes calorie requirements need to be worked out what is required every day before any training is added in. To do this the same calculation was made as the female runner, except instead of 8.7 x kg it is 14.7 x kg and 496 is added instead of 829, this is because this athlete is in a different age group. Again activity requirement is taken into consideration, at 450 calories an hour, and as exact training figures are not available it has been estimated at 6 hours training a week, which then works out as an extra 2700 calories a week. This figure is then divided by 7 to give the extra calories needed each day. So this athlete needs a total of 3384 calories a day to maintain her current stature. Again the daily allowance needs to be divided between the macronutrients. According to National Institute of Nutrition (2007) this athlete needs CHO:Lipids:Protein at 60:25:15. Once again the calories are converted into grams. See Appendix 1. Using this information there was a deficit across the board, see Appendix 2. When analysing her food diary it has been noted that very little water had been consumed, she only had 3 litres over the 3 days but she did consume a bottle of lucozade on 2 of the 3 days. However she did have a bottle of wine, which took up a massive 9% of her 3 days allowance. Alcohol is not good for you as it dehydrates the body, which in turn makes it harder to train the following day. Very little fresh
