ACSM Personal Trainer Certification Practice Exam

For athletes, what is the recommended protein intake per kilogram of body weight?

1. 0.8-1.0 g/kg BW

2. 1.0-1.2 g/kg BW

3. 1.2-1.7 g/kg BW

4. 1.5-2.0 g/kg BW

The correct answer is: 1.2-1.7 g/kg BW

The recommended protein intake for athletes falls within the range of 1.2 to 1.7 grams per kilogram of body weight. This level of protein intake is considered optimal for supporting muscle repair, growth, and overall performance enhancement, especially in athletes who engage in regular intense training. Athletes have increased protein needs compared to the general population due to the physiological demands of their training. Consuming protein within this range helps athletes maintain muscle mass, recover effectively after workouts, and adapt to their training regimens. The emphasis on protein intake also reflects the understanding that various types of exercise, such as strength training and endurance activities, necessitate adequate protein to facilitate recovery and improve performance. Lower protein intake values, such as those suggested in the first two options (0.8-1.0 g/kg and 1.0-1.2 g/kg), may be suitable for sedentary individuals or those with lower energy expenditure and do not account for the increased demands placed on athletes' bodies. The higher range offerings, like 1.5-2.0 g/kg, may exceed what is necessary for most athletes and could potentially lead to unnecessary caloric intake or stress on the body’s metabolic processes if not balanced appropriately with fats and carbohydrates.
