Question 1:
Which of the following nutrients is the primary source of energy for the body during exercise?
a) Carbohydrates
b) Proteins
c) Fats
d) Vitamins
Answer: a) Carbohydrates
Explanation: Carbohydrates are the primary source of energy for the body during exercise. They are broken down into glucose, which is then used by the muscles as fuel. Without enough carbohydrates, the body will rely on other sources of energy, such as proteins or fats, which are less efficient and can lead to fatigue. For example, a runner who consumes a carbohydrate-rich meal before a race will have more energy and endurance compared to a runner who does not.
Question 2:
Which of the following nutrients is important for muscle repair and growth?
a) Carbohydrates
b) Proteins
c) Fats
d) Minerals
Answer: b) Proteins
Explanation: Proteins are important for muscle repair and growth. They are made up of amino acids, which are the building blocks of muscles. During exercise, muscles undergo small tears and proteins help in repairing and rebuilding these muscles. For example, a weightlifter who consumes an adequate amount of protein in their diet will have better muscle recovery and growth compared to someone who does not.
Question 3:
Which of the following nutrients is important for maintaining hydration during exercise?
a) Carbohydrates
b) Proteins
c) Fats
d) Electrolytes
Answer: d) Electrolytes
Explanation: Electrolytes, such as sodium and potassium, are important for maintaining hydration during exercise. They help in regulating fluid balance in the body and are lost through sweat during physical activity. Replenishing electrolytes is crucial to prevent dehydration and muscle cramps. For example, a long-distance runner who consumes a sports drink containing electrolytes will be able to maintain hydration and prevent fatigue compared to someone who only drinks water.
Question 4:
Which of the following nutrients is important for long-lasting energy during endurance activities?
a) Carbohydrates
b) Proteins
c) Fats
d) Fiber
Answer: c) Fats
Explanation: Fats are an important source of long-lasting energy during endurance activities. They are a dense source of calories and can provide sustained energy for prolonged periods. However, fats take longer to digest compared to carbohydrates, so they are not ideal for high-intensity activities. For example, a cyclist who consumes a meal containing healthy fats, such as avocados or nuts, before a long-distance ride will have a steady supply of energy throughout the activity.
Question 5:
Which of the following nutrients is important for bone health and strength?
a) Carbohydrates
b) Proteins
c) Fats
d) Calcium
Answer: d) Calcium
Explanation: Calcium is important for bone health and strength. It is a mineral that plays a crucial role in building and maintaining strong bones. Adequate calcium intake is essential for athletes, as they are at a higher risk of developing bone injuries or conditions such as stress fractures. For example, a teenage soccer player who consumes calcium-rich foods, such as dairy products or leafy green vegetables, will have a reduced risk of bone injuries compared to someone with low calcium intake.
