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 37.9

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 these steps:

  1. Subtract the exercise energy expenditure from the total energy intake: 3000 kcal - 600 kcal = 2400 kcal
  2. Divide the result by the body weight: 2400 kcal / 70 kg = 34.29 kcal/kg
  3. Adjust the EA score for body composition:

EA score = (EA score from step 2) / (1 - (body composition / 100))

EA score = 34.29 kcal/kg / (1 - (18 / 100)) = 41.8

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