------------------------------------------------ Determine the Estimated Energy Requirement (EER) for a 45-year-old male athlete who weighs 187 lbs and is 6 ft 0 in. His activity level is active.

a) 3157
b) 3819
c) 2806
d) 2495

The Estimated Energy Requirement (EER) for a 45-year-old male athlete who is active, weighs 187 lbs, and is 6 ft tall is approximately 2,989 kilocalories per day. The closest option provided is (c) 2806.

Explanation:

To determine the Estimated Energy Requirement (EER) for a 45-year-old male athlete who is physically active, weighs 187 lbs (84.82 kg), and is 6 ft (1.83 m) tall, we use the standardized formula for adult males. Given that the activity level is 'active', this typically corresponds to a physical activity (PA) level coefficient that can range from 1.11 to 1.25 depending on the intensity of the activities. We will choose a midpoint value of 1.18 for an active lifestyle.

The formula for EER for an adult male is:

EER = 662 - (9.53 × age) + PA × (15.91 × weight in kg + 539.6 × height in m)

Using the provided data and assuming the active PA coefficient:

EER = 662 - (9.53 × 45) + 1.18 × (15.91 × 84.82 + 539.6 × 1.83)

Calculating this yields:

EER = 662 - 428.85 + 1.18 × (1348.3252 + 986.748)

EER = 662 - 428.85 + 1.18 × 2335.0732

EER = 662 - 428.85 + 2755.386376

EER = 2988.536376

Therefore, rounding to the nearest whole number, the Estimated Energy Requirement for this individual is approximately 2,989 kilocalories per day. The closest answer from the given options would be (c) 2806.
