Shana is a competitive athlete who weighs 135 lb. she would like to plan a nutritionally adequate diet that provides enough carb
prisoha [69]
The correct answer is d.

Carbohydrates are a very important part of an athlete's diet, since they provide the necessary energy for competition and endurance, but also help in the process of muscle gain.

The amount of carbohydrates that Shana should consume depend heavily on the intensity of her exercise activities. For a moderate level of exercise, which equals to 1 hour of exercise daily, a person should consume 5-7 g/kg of body weight. For a high level of exercise (1-3 hours of daily exercise), a person should consume 6-10 g/kg.

Guessing that Shana will perform a high level of exercise and based on her weight (135 lb or 61.2 kg), Shana should consume 366 to 610 g of carbohydrates daily.
