Question 1

What is the primary energy system used during a 100-meter sprint?

Accepted Answer

ATP-PCr (phosphagen) system

Answer

The ATP-PCr system provides immediate energy for maximal-intensity efforts lasting 1–10 seconds, making it the dominant system during a 100-meter sprint.

Question 2

How many calories per gram does dietary fat provide?

Accepted Answer

9 kcal

Answer

Dietary fat provides 9 kcal per gram, making it the most calorie-dense macronutrient compared to carbohydrates and protein (4 kcal/g each).

Question 3

What is the recommended post-exercise protein dose to maximize muscle protein synthesis in most athletes?

Accepted Answer

20–40 g

Answer

Research consistently shows that 20–40 g of high-quality protein post-exercise is sufficient to maximize muscle protein synthesis, with larger doses providing no additional benefit.

Question 4

Glycogen is stored primarily in which two tissues of the body?

Accepted Answer

Liver and skeletal muscle

Answer

Glycogen is stored primarily in the liver (for blood glucose regulation) and skeletal muscle (for local energy use during exercise).

Question 5

Which simple, non-invasive indicator do athletes most commonly use to monitor daily hydration status?

Accepted Answer
