Dietary macro- and micronutrient requirements of endurance athletes

Dietary macro- and micronutrient requirements of endurance athletes.

Most endurance athletes train for many hours per week to compete in events which generally last no longer than 23 h. However, there are exceptions and these include the full-course triathlon in which competitors swim 2.5 km (l.Smiles), cycle 180km (112miles) and finally run 42.2 km (26.2 miles). Elite athletes win this competition in a little over 8 h. In cycling, there are competitions which l...

Micronutrient requirements for athletes.

Vitamins and minerals are necessary for many metabolic processes in the body and are important in supporting growth and development. Vitamins and minerals also are required in numerous reactions involved with exercise and physical activity, including energy, carbohydrate, fat and protein metabolism, oxygen transfer and delivery, and tissue repair. The vitamin and mineral needs of athletes have ...

Fluid Requirements of Endurance Athletes

Protein requirements for endurance athletes.

Acute endurance exercise results in the oxidation of several amino acids. The total amount of amino acid oxidation during endurance exercise amounts to only 1-6% of the total energy cost of exercise. The branched chain amino acid, leucine, has been most often studied in relation to endurance exercise. Leucine is oxidized by the enzyme, branched-chain oxo-acid dehydrogenase (BCOAD). BCOAD is rel...

Different nutrient and energy requirements for endurance and resistance athletes

I am a second year Nutrition student and have a question about protein and endurance athletes. Why are their protein requirements greater than they are for resistance athletes? Is it because the muscle glycogen stores get depleted over a long period of time with intense exercise? If so, should they consume more carbohydrates than resistance athletes, with a low glycemic index prior to their wor...
