Final answer:
For a 25-year-old female endurance athlete with 20% body fat and 52.7 kg of fat-free mass, her estimated RMR is 1509.92 calories per day.
Explanation:
The Cunningham Equation is used to estimate the resting metabolic rate (RMR) of an individual. It takes into account the person's weight, height, age, and body composition. To calculate the RMR, you need to know the specific metabolic rate of fat-free mass (FFM) and fat mass (FM).
Since the individual in question is a 25-year-old female endurance athlete, her FFM can be estimated as 52.7 kg. Using the Cunningham Equation, the RMR can be calculated as:
RMR = 370 + (21.6 x FFM)
Substituting the value of FFM into the equation:
RMR = 370 + (21.6 x 52.7)
= 370 + 1139.92
= 1509.92 calories per day
Therefore, the correct answer is 1509.92 calories per day.
