    Study Notes

    Macronutrients

    • Macronutrients are needed in large amounts for energy and bodily functions.
    • Essential for moderate to vigorous physical activity.
    • Provide fuel for physical exertion.

    Key Macronutrients: Carbohydrates

    • Function: Primary source of energy, especially during intense activity. Broken down into glucose for muscle energy.
    • Sources: Whole grains (brown rice, oats), fruits, vegetables, legumes.
    • Example: A marathon runner would consume a high-carbohydrate meal (pasta) to "carb-load".

    Key Macronutrients: Proteins

    • Function: Essential for muscle repair and growth. Muscle tears after exercise are repaired and built by protein.
    • Sources: Lean meats (chicken, turkey), dairy (yogurt, milk), legumes (lentils, chickpeas), nuts.
    • Example: Bodybuilders might consume protein shakes post-workout.

    Key Macronutrients: Fats

    • Function: Secondary energy source, important for hormone production, joint lubrication, and absorbing fat-soluble vitamins (A, D, E, K).
    • Sources: Healthy fats from avocados, nuts, seeds, olive oil, and fatty fish.
    • Example: Endurance cyclists might rely more on fat as energy during the second half of a long ride.

    Micronutrients

    • Vitamins and minerals needed in smaller amounts.
    • Crucial for supporting metabolism, immune function, and bone health.
    • Important for energy production and recovery.

    Key Micronutrients: Iron

    • Function: Essential for oxygen transport in the blood, supporting muscle energy demands.
    • Sources: Red meat, leafy greens, fortified cereals, legumes.
    • Example: Female athletes need to monitor iron levels to prevent anemia.

    Key Micronutrients: Calcium & Vitamin D

    • Function: Calcium supports bone health and muscle function, while vitamin D aids in calcium absorption.
    • Sources: Dairy products, fortified plant-based milks, leafy greens, sunlight.
    • Example: Tennis players need adequate calcium intake to prevent stress fractures.

    Key Micronutrients: Magnesium

    • Function: Supports muscle relaxation and function, and plays a role in energy production.
    • Sources: Nuts, seeds, whole grains, leafy greens.
    • Example: Weightlifters can use magnesium-rich foods (like almonds, spinach) to help reduce muscle cramps.

    Hydration

    • Function: Essential for regulating body temperature, nutrient transport, and waste elimination.
    • Recommendations: Athletes need to drink 17-20 oz of water 2-3 hours before exercise, and additional fluid (7-10 oz) every 10-20 minutes during activity. replenish fluids after exercise.
    • Example: Soccer players in hot weather must drink water frequently during matches to avoid dehydration.

    Fad Diets

    • Restrictive eating plans, often promising rapid weight loss.
    • Often not sustainable or balanced.
    • May lead to nutrient deficiencies, poor energy availability, and impaired performance in athletes.
    • Example: Keto diet, intermittent fasting may be problematic for athletes requiring more carbohydrates.

    Conclusion

    • Understanding macronutrients, micronutrients, hydration, and avoiding fad diets is vital for athletes.
    • Balanced diet with sufficient nutrients enables athletes to maintain energy, improve performance, and prevent injuries.
