Question 1

What is the primary role of carbohydrates in sport performance?

Accepted Answer

Providing a readily available energy substrate for high-intensity exercise

Answer

Carbohydrates serve as the primary fuel source for high-intensity exercise by providing glucose and replenishing muscle glycogen stores.

Question 2

According to current evidence, what daily protein intake is generally recommended for strength and power athletes engaged in heavy resistance training?

Accepted Answer

1.6–2.2 g/kg body weight

Answer

Research supports 1.6–2.2 g/kg/day for maximizing muscle protein synthesis and lean mass adaptation in resistance-trained athletes.

Question 3

Which ergogenic aid has the strongest evidence base for improving short-duration, high-intensity exercise performance?

Accepted Answer

Creatine monohydrate

Answer

Creatine monohydrate is classified as the most evidence-backed ergogenic supplement for enhancing phosphocreatine resynthesis and high-intensity output.

Question 4

What is the recommended carbohydrate intake during continuous endurance exercise lasting more than 60 minutes?

Accepted Answer

30–60 g per hour

Answer

Consuming 30–60 g of carbohydrate per hour during prolonged exercise helps maintain blood glucose and delay fatigue.

Question 5

Which vitamin and mineral combination is most critical for bone health in athletes, particularly in female athletes at risk for the Female Athlete Triad?
