A marathon is a long distance running race that is about 26.2 miles long. Finishing times range from 2 hours to 8 hours. Running a marathon requires the use of your aerobic energy system. The energy source will be coming from glycogen, fats and proteins. The duration of the activity lasts longer than just a couple minutes; therefore Mary will be using her aerobic energy system. She will be working at a steady-state low intensity. She is only focusing on her performance since this is not a team sport.
Section 2: Training Nutrition Plan
Protein:
Mary Thon is an endurance athlete. According to the ADA, ACSM and DC, an endurance athlete needs 1.2-1.4g per kilogram of protein per day. I would recommend she consume approximately 1.2g of protein per kilogram (71g).
Carbohydrates:
The ADA, ACSM, DC paper recommends athletes to consume 6-10g per kilogram per day (Collier, 2014). I would recommend she consume approximately 8g of carbohydrates per kilogram per day (472g).
Fats:
Fat is vital to human health and physical performance (Collier, 2014). I recommend less than 20% of calories should be consumed by fat in Mary’s diet.
Hydration:
Endurance athletes should attempt to minimize dehydration and limit body mass losses through sweating to 2–3% of body mass (Jeukendrup A, 2011). If an
