NASM Applied Sciences & Nutrition 2 — Questions and Answers
Question 1: Which macronutrient provides 4 calories per gram and is the body's preferred energy source during high-intensity exercise?
- Fat
- Carbohydrate (Correct answer)
- Protein
- Alcohol
Correct answer: Carbohydrate
Carbohydrates provide 4 kcal/g and are the primary fuel for high-intensity, glycolytic activity.
Question 2: According to NASM, what is the general daily protein recommendation for a healthy adult engaged in resistance training?
- 0.3-0.5 g/kg of body weight
- 1.2-1.7 g/kg of body weight (Correct answer)
- 3.0-4.0 g/kg of body weight
- 0.8 g/kg of body weight
Correct answer: 1.2-1.7 g/kg of body weight
Active individuals doing resistance training typically need roughly 1.2-1.7 g of protein per kilogram of body weight.
Question 3: Which energy system is the predominant supplier of ATP during an all-out 8-second sprint?
- Oxidative (aerobic) system
- ATP-PC (phosphagen) system (Correct answer)
- Glycolytic system
- Beta-oxidation
Correct answer: ATP-PC (phosphagen) system
The ATP-PC system supplies immediate energy for very short, maximal efforts lasting roughly 10 seconds or less.
Question 4: How many calories are stored in one gram of dietary fat?
- 4 calories
- 7 calories
- 9 calories (Correct answer)
- 2 calories
Correct answer: 9 calories
Fat is the most energy-dense macronutrient at 9 kcal per gram.
Question 5: What is the recommended general fluid guideline NASM cites for maintaining hydration before exercise?
- Drink only when thirsty during the workout
- Consume 14-22 oz of fluid about 2 hours before exercise (Correct answer)
- Avoid all fluids 2 hours before exercise
- Drink 1 gallon immediately before exercise
Correct answer: Consume 14-22 oz of fluid about 2 hours before exercise
Pre-exercise hydration guidelines suggest roughly 14-22 oz of fluid about two hours beforehand.
Question 6: Which vitamin is fat-soluble and therefore stored in the body rather than excreted readily?
- Vitamin C
- Vitamin B12
- Vitamin D (Correct answer)
- Folate
Correct answer: Vitamin D
Vitamin D is one of the fat-soluble vitamins (A, D, E, K) that are stored in body fat and the liver.
Question 7: A client wants to lose fat. What does NASM identify as the fundamental requirement for weight loss?
- Eliminating all carbohydrates
- A negative caloric balance (energy deficit) (Correct answer)
- Eating only protein
- Exercising on an empty stomach
Correct answer: A negative caloric balance (energy deficit)
Fat loss fundamentally requires expending more energy than is consumed, creating a caloric deficit.
