Calculate the Energy Availability (EA) score for the following individual:

- Total energy intake = 3,000 kcal
- Exercise Energy Expenditure = 600 kcal
- Total body weight = 70 kg (154 lb)
- Body composition = 18%

A. EA score equals 41.8
B. EA score equals 44.6
C. EA score equals 35.9
D. EA score equals 37.3

Answer :

Final answer:

The Energy Availability (EA) score for the given individual is 41.8.

Explanation:

To calculate the Energy Availability (EA) score, we need to follow the given steps:

  1. Step 1: Subtract the exercise energy expenditure from the total energy intake.
  2. Step 2: Adjust the result from Step 1 for body weight and body composition.

Let's calculate the EA score:

  1. Step 1: Total energy intake - Exercise energy expenditure = 3,000kcal - 600kcal = 2,400kcal
  2. Step 2: Adjust for body weight and body composition. Multiply the result from Step 1 by the body weight in kilograms and divide by 1000. Then, divide the result by the body composition percentage.

EA score = (2,400kcal * 70kg) / 1000 / 18% = 41.8

Therefore, the correct answer is A. EA score equals 41.8.
