Answer 1

Answer:

• Based on the Nutrition and dietetics recommendation, a player should consume a maximum of 4.5 grams of carbohydrates per pound of the body weight per day.

Blak weighs = 176 pounds

Recommended carbohydrate = 4.5 g per pound.

Blake consuming = 176 X 4.5

= 792 grams of carbohydrates per day.

Blake consumes 792 grams of carbohydrates on a daily basis.

• Blake daily caloric intake = 3200 calories.

Each calorie contains 4 grams of carbohydrates.

Therefore, Blake consumes = 3200 / 4

= 800grams of carbohydrates.

Blake consumes around 800 g of carbohydrates from his daily calorie intake.

• Prior to the practice of 0 - 4 hours, Blake should consume at least 1 - 4 g of carbohydrate per kg body weight. Because it helps him to do endurance performance.

Blake weight = 176 pounds

Convert weight into kg = 176 / 2.2

= 80kg.

Carbohydrate consumption = 80 X 4

= 320g of carbohydrates.

Blake should consume at least 320g of carbohydrates 0-4 hours prior to the practice.

• Each calorie contains 4 grams of carbohydrates.

320g of carbohydrates contain = 320 X 4

= 1280 calories per day.

Blake consumes 1280 calories 0- 4 hours prior to the practice.   

• Immediately after exercise, Blake should consume 1.2 g of carbohydrates per kg of body weight.

Carbohydrate consumption = 80 X 1.2

= 96 grams of carbohydrates.

Blake should consume 96g of carbohydrates immediately after practice to refill the energy.

• 96 X 4 = 384 calories.

Blake should consume 384 calories of carbohydrates immediately after practice.
