Question 1

What nutrient is the main energy source during exercise?

Accepted Answer

Carbohydrates

Answer

Carbohydrates are the body's preferred and most efficient source of energy, especially during moderate to high-intensity exercise. They are broken down into glucose, which is stored as glycogen in the muscles and liver. This glycogen is readily converted back to glucose to fuel muscular contractions, making them essential for sustaining athletic performance.

Question 2

Why is protein important for athletes?

Accepted Answer

Muscle repair

Answer

Protein is crucial for athletes because it provides the amino acids necessary for muscle repair, recovery, and growth. During intense exercise, muscle fibers experience microscopic damage, and protein intake helps to rebuild and strengthen these tissues. Adequate protein also supports the synthesis of enzymes, hormones, and other vital compounds for overall athletic function.

Question 3

What is hydration’s role in performance?

Accepted Answer

Maintains performance

Answer

Proper hydration is vital for maintaining optimal athletic performance. Water regulates body temperature, lubricates joints, transports nutrients, and helps prevent fatigue and muscle cramps. Even mild dehydration can significantly impair endurance, strength, and cognitive function, making consistent fluid intake essential for athletes.

Question 4

What does creatine supplement support?

Accepted Answer

Strength and power

Answer

Creatine is a well-researched supplement known to enhance strength and power output, particularly during short bursts of high-intensity exercise. It works by increasing the body's stores of phosphocreatine, which helps to rapidly regenerate ATP (adenosine triphosphate), the primary energy currency for muscle contractions. This allows athletes to perform more reps or generate more force in activities like weightlifting or sprinting.

Question 5

What is a pre-workout meal designed for?

Accepted Answer

Energy and endurance

Answer

A pre-workout meal is strategically consumed to provide the body with readily available energy for the upcoming exercise session. It typically focuses on carbohydrates to top off glycogen stores, ensuring sustained energy and endurance throughout the workout. This helps prevent fatigue and optimizes performance by fueling muscle activity.
