Soc 25- Energy Use, Diet, Nutrition And Hydration Flashcards
What is a balanced diet?
A balanced diet provides the body with essential nutrients in the right proportions, including carbohydrates, fats, proteins, vitamins, minerals, water, and fibre.
Why is a balanced diet needed in sport?
It ensures energy, supports growth, and promotes overall health, preventing deficiencies and reducing the risk of chronic diseases.
What are macronutrients?
Macronutrients are the types of food that you need in large amounts, including carbohydrates, fats, and proteins.
Why are carbohydrates essential for athletes?
Carbohydrates provide the primary fuel for physical activity, especially during high-intensity or prolonged exercise.
How do carbohydrates help athletes?
They help maintain energy levels, delay fatigue, and support recovery.
Where are carbohydrates stored in the body?
Carbohydrates are stored in the muscles and the liver as glycogen.
What are simple carbohydrates?
Simple carbohydrates are sugars that provide a quick energy source, found in sugar, fruits, and sweets.
What are complex carbohydrates?
Complex carbohydrates are starches that provide a longer-lasting release of energy, found in foods like bananas, brown rice, pasta, and potatoes.
What is the role of fats in sports?
Fats provide a concentrated energy source, essential for long-duration, moderate-intensity sports.
How do healthy fats benefit athletes?
They enhance energy efficiency and long-term resilience by sparing glycogen stores and fueling aerobic activity.
What is the importance of proteins for athletes?
Proteins support muscle repair, recovery, and growth, crucial for athletic performance.
What are the sources of protein?
Sources include lean meats, eggs, dairy, and plant-based options.
What are micronutrients?
Micronutrients are parts of food needed for normal growth but only in small amounts, including vitamins, minerals, water, and fibre.
What are the essential functions of vitamins?
Vitamins are essential for good vision, skin health, red blood cell formation, healing, healthy bones and teeth, and blood clotting.
What are two key minerals needed by sportspersons?
Calcium and iron.
What is the role of calcium?
Calcium increases the strength of bones.
What is the role of iron?
Iron increases the oxygen-carrying capacity in the blood.
Why is water important for athletes?
Water transports nutrients, waste, and hormones while regulating electrolyte distribution.
What happens to electrolytes during exercise?
Sweating leads to the loss of electrolytes, making hydration crucial for performance.
What is the role of fibre in an athlete’s diet?
Fibre supports the digestive system, helping eliminate waste products efficiently and maintaining digestive health.
How does fibre contribute to overall well-being?
It helps prevent potential diseases and ensures that the body functions optimally for performance and recovery.
