What is the role of carbohydrates in post-workout recovery?
✔✔ Carbohydrates help replenish glycogen stores that are depleted during exercise, aiding in
muscle recovery and restoring energy levels.
How can protein intake influence muscle growth?
✔✔ Adequate protein intake provides the essential amino acids necessary for muscle repair and
growth, supporting increased muscle mass over time.
What are the benefits of including healthy fats in a fitness nutrition plan?
✔✔ Healthy fats support hormone production, provide long-lasting energy, and aid in the
absorption of fat-soluble vitamins.
How does hydration affect exercise performance and recovery?
1
,✔✔ Proper hydration helps maintain fluid balance, regulate body temperature, and support
efficient muscle function, which improves performance and speeds up recovery.
Why is it important to consume a balanced diet for overall fitness?
✔✔ A balanced diet ensures that the body receives all essential nutrients—carbohydrates,
proteins, fats, vitamins, and minerals—necessary for optimal health, performance, and recovery.
What impact does timing of nutrient intake have on exercise outcomes?
✔✔ Timely nutrient intake, such as consuming protein and carbohydrates around workouts, can
enhance muscle repair, replenish glycogen stores, and improve exercise performance.
How does fiber contribute to overall health and fitness?
✔✔ Fiber aids in digestion, helps regulate blood sugar levels, and contributes to a feeling of
fullness, which can assist in weight management and overall health.
2
, What role do antioxidants play in a fitness nutrition plan?
✔✔ Antioxidants help combat oxidative stress and inflammation caused by intense exercise,
supporting recovery and reducing the risk of exercise-induced damage.
How does maintaining electrolyte balance support physical performance?
✔✔ Maintaining electrolyte balance is crucial for proper muscle function, nerve transmission,
and fluid regulation, which supports overall physical performance and prevents cramping.
What is the significance of micronutrients in supporting exercise recovery?
✔✔ Micronutrients, such as vitamins and minerals, play key roles in energy production, immune
function, and muscle repair, all of which are vital for effective exercise recovery.
Macronutrients ✔✔A type of food required in large amounts in the diet.
Organelles ✔✔Structures in living cell performing specialized metabolic tasks.
