NASM - National Academy of Sports Medicine Applied Sciences & Nutrition Questions and Answers 1 — Questions and Answers
Question 1: A client who engages in high-intensity endurance exercise for 90-120 minutes daily is seeking guidance on post-exercise nutrition for optimal recovery. Within the scope of practice for a NASM Certified Personal Trainer, which recommendation is most appropriate to facilitate glycogen replenishment?
- "Consume a meal with 2.0 g/kg of protein and 1.0 g/kg of carbohydrates within 3 hours."
- "You should implement a carbohydrate loading strategy, consuming 10-12 g/kg of carbohydrates daily."
- "Aim to consume 1.0-1.2 g/kg of carbohydrates within the first hour after your workout." (Correct answer)
- "A liquid meal replacement with a 1:1 ratio of protein to carbohydrates is best after every session."
Correct answer: "Aim to consume 1.0-1.2 g/kg of carbohydrates within the first hour after your workout."
For optimal glycogen resynthesis after prolonged, intense exercise, it is recommended to consume 1.0-1.2 g/kg of body weight of carbohydrates within the first hour post-exercise. This window is when muscles are most receptive to restoring glycogen stores.
Question 2: Which of the following B vitamins acts as a cofactor in carboxylase enzymes, playing a role in the metabolism of carbohydrates, fats, and amino acids?
- Riboflavin (B2)
- Biotin (B7) (Correct answer)
- Pyridoxine (B6)
- Cobalamin (B12)
Correct answer: Biotin (B7)
Biotin (B7) is a crucial cofactor for several carboxylase enzymes that are essential for metabolic processes, including the metabolism of carbohydrates, fats, and amino acids.
Question 3: A personal trainer is working with a new client who has type 2 diabetes and wants to lose weight. The client asks for a specific meal plan that eliminates all carbohydrates. Which of the following is the most appropriate course of action for the trainer?
- Provide a 7-day low-carbohydrate meal plan based on publicly available health guidelines.
- Educate the client on the role of carbohydrates, fats, and proteins and suggest they consult with a Registered Dietitian for medical nutrition therapy. (Correct answer)
- Prescribe a specific vitamin and mineral supplement regimen to compensate for the lack of carbohydrates.
- Design an exercise program and advise the client to follow a ketogenic diet found on a popular health blog.
Correct answer: Educate the client on the role of carbohydrates, fats, and proteins and suggest they consult with a Registered Dietitian for medical nutrition therapy.
It is outside the scope of practice for a personal trainer to prescribe specific meal plans or provide medical nutrition therapy, especially for a client with a medical condition like diabetes. The appropriate action is to provide general nutrition education and refer the client to a qualified medical professional, such as a Registered Dietitian, for personalized dietary prescription.
Question 4: What is the primary role of micronutrients in the body, particularly concerning energy metabolism?
- They are the main source of calories for ATP production during high-intensity exercise.
- They provide the structural components for building and repairing muscle tissue.
- They act as cofactors and coenzymes in metabolic reactions that produce energy. (Correct answer)
- They primarily regulate fluid balance and nerve impulse transmission.
Correct answer: They act as cofactors and coenzymes in metabolic reactions that produce energy.
Micronutrients, which include vitamins and minerals, do not provide energy directly. Instead, they are essential as cofactors and coenzymes for the metabolic pathways that break down macronutrients (carbohydrates, fats, and proteins) to produce ATP.
Question 5: A 180-lb (81.8 kg) client performs an intense workout on a hot day and weighs themselves before and after the session. They notice a 3-pound (1.36 kg) weight loss. To properly rehydrate, what is the minimum amount of fluid they should consume?
- 16-24 oz
- 30-36 oz
- 48-60 oz (Correct answer)
- 60-72 oz
Correct answer: 48-60 oz
For every pound of body weight lost during exercise, it is recommended to consume 16-24 ounces (or 125-150% of the fluid lost). A 3-pound weight loss equates to 48 ounces. Therefore, the client should aim to consume at least 48 to 72 ounces of fluid to properly rehydrate.
Question 6: The Thermic Effect of Food (TEF) accounts for a portion of Total Daily Energy Expenditure (TDEE). Which macronutrient has the highest thermic effect?
- Carbohydrates
- Fat
- Alcohol
- Protein (Correct answer)
Correct answer: Protein
The Thermic Effect of Food (TEF) is the energy expended for digestion, absorption, and metabolism of nutrients. Protein has the highest TEF, requiring more energy to process compared to carbohydrates and fats. TEF typically accounts for about 6-10% of total energy expenditure.
