    Study Notes

    Macronutrients

    • Carbohydrates:
      • Primary source of energy for muscles and brain during exercise
      • Broken down into glucose, stored as glycogen, and used for energy during physical activity
      • Adequate intake improves endurance and delays fatigue
      • Types: focus on complex carbohydrates like whole grains, fruits, vegetables, and legumes for sustained energy release
    • Proteins:
      • Vital for muscle repair, growth, and overall health
      • Helps build and maintain bones and teeth, and supports nerve and muscle function
      • Important for immune function, protein synthesis, and wound healing
      • Types: focus on high-quality sources like lean meats, poultry, fish, eggs, dairy products, legumes, and plant-based sources
    • Fats:
      • Essential macronutrient providing a concentrated source of energy and supporting overall health
      • Rich source of energy, especially during low to moderate-intensity exercise and endurance activities

    Micronutrients

    Vitamins

    • Vitamin A: helps body use carbohydrates, proteins, and fats; maintains healthy skin, bones, teeth, and hair; aids vision
    • Vitamin B: essential for brain function, cell metabolism, and energy level
    • Vitamin B12: aids in maintenance of red blood cells
    • Vitamin C: important for immune function and collagen synthesis
    • Vitamin E: helps protect the body from oxidative damage

    Minerals

    • Folate: aids in the formation of red blood cells and protein
    • Iron: helps regulate chemical reactions in the body; important for transporting oxygen through the bloodstream; prevents anemia
    • Calcium: essential for bone, teeth, and skin formation and resistance; important for muscle function and nerve transmission
    • Zinc: important for immune function, wound healing, and protein synthesis

    Hydration and Electrolytes

    • Electrolytes (sodium, potassium, and chloride) are essential for maintaining fluid balance, muscle function, and nerve transmission
    • Athletes lose electrolytes through sweat, so it's important to replenish them through hydration and proper nutrition
    • Hydration guidelines: drink water regularly throughout the day, before, during, and after exercise to maintain hydration
    • Monitoring urine color and body weight changes can help athletes assess their hydration status

    Pre- and Post-Exercise Nutrition

    • Proper food intake before exercise increases endurance and performance
    • Consume water and easily digestible carbohydrates 3-4 hours before exercise
    • Consume carbohydrates within 30 minutes after exercise to replenish glycogen stores and promote faster recovery
    • Include protein in post-workout meals or snacks to stimulate muscle protein synthesis and aid in recovery
    • Distribute protein intake evenly throughout the day and consume protein-rich foods within 30 minutes to two hours post-exercise
