How the type of Sport influence protein requirements?

The type of sport and total calorie intakes influence protein requirements. Eating sufficient foods to meet high energy requirements ensures that athletes will meet their protein requirements. However, high protein diets increase the water requirement necessary to eliminate nitrogen through the urine. Also, an increase in metabolic rate can occur and therefore, increased oxygen consumption. A diet providing good quality protein from animal sources or vegetable sources (supplementation with first class protein or using complementary sources together) in the amount constituting 15-20% of total calories is sufficient for an athlete. No supplementation above this level is required for any kind of sport.
