Free CSN Nutrition & Health Assessment Questions and Answers

Question 1

Which macronutrient is the primary energy source during high-intensity exercise?

Accepted Answer

Carbohydrates

Answer

Carbohydrates are the body's preferred and most efficient source of energy, especially during high-intensity exercise. They are broken down into glucose, which is then used to fuel muscles and the brain. Adequate carbohydrate intake ensures glycogen stores are sufficient to sustain performance during strenuous activity.

Question 2

Which vitamin is essential for calcium absorption?

Accepted Answer

Vitamin D

Answer

Vitamin D is crucial for calcium absorption in the gut and for maintaining proper calcium and phosphate levels in the body. Without sufficient Vitamin D, the body cannot effectively absorb calcium, which is essential for strong bones, muscle function, and nerve transmission.

Question 3

What is the main function of protein in sports nutrition?

Accepted Answer

Repair and build muscle tissue

Answer

The main function of protein in sports nutrition is to repair damaged muscle fibers and build new muscle tissue, a process known as muscle protein synthesis. After exercise, especially resistance training, protein intake is critical for recovery, adaptation, and increasing muscle mass and strength.

Question 4

Which mineral is most commonly lost through sweat during exercise?

Accepted Answer

Sodium

Answer

Sodium is the most commonly lost electrolyte through sweat during exercise, particularly in hot and humid conditions or during prolonged activity. It plays a vital role in fluid balance, nerve function, and muscle contractions. Replenishing sodium is essential to prevent hyponatremia and maintain performance.

Question 5

What is the recommended daily protein intake for strength athletes?

Accepted Answer

1.2–2.0 g/kg

Answer

For strength athletes, a higher protein intake is recommended to support muscle repair, growth, and recovery from intense training. The general consensus suggests a daily intake ranging from 1.2 to 2.0 grams of protein per kilogram of body weight, which is significantly higher than for sedentary individuals.
