Nutritional Considerations

Importance of Nutrition

  • Nutrition positively contributes to:

    • Strength

    • Flexibility

    • Cardiorespiratory Endurance

    • Performance vs. Food consumption

    • Myths vs. physiological benefits

    • Psychological vs. physiological considerations

Food Groups

  • Food pyramid categories:

    • Grain Group: 6-11 servings

    • Vegetable Group: 3-5 servings

    • Fruit Group: 2-4 servings

    • Milk Group: 3-4 servings

    • Meat Group: 2-3 servings

    • Others (fats, oils & sweets): eat sparingly

Nutritional Basics

Key Nutrients

  • Essential nutrients:

    • Carbohydrates

    • Proteins

    • Fats

    • Vitamins

    • Minerals

    • Water

Role of Nutrients

  • Three primary roles:

    • Growth, maintenance, and repair of cells

    • Regulation of body processes

    • Supply energy for cells

Carbohydrates

Types of Carbohydrates

  • Simple Sugars:

    • Monosaccharides and Disaccharides

    • <15% of caloric intake

  • Starches (Complex Carbohydrates):

    • Source: Rice, potatoes, breads

    • Stored as glycogen for energy use

Carbohydrate Requirements

  • Daily intake:

    • 60-70% of total calories

    • Complex carbs: 50-60%

    • Simple sugars: <10%

Fats

Roles of Fats

  • Most concentrated energy source

  • Essential for growth and development

  • Serves flavor and aids in vitamin absorption

Types and Requirements

  • Saturated vs. Unsaturated fats:

    • <25% of caloric intake

  • Daily intake:

    • 25% of total calories

    • 69 grams of fat per day

Proteins

Importance and Requirements

  • Functions:

    • Tissue growth, maintenance, enzyme production

    • 12-15% of daily caloric intake

  • Amino Acids:

    • 9 essential and 13 non-essential

Daily Protein Calculation

  • RDA: 0.8g/kg of body weight

  • Athlete: 1g/2.2lbs of body weight

Vitamins

Functions and Classifications

  • Essential for:

    • Metabolizing nutrients, growth, and maintenance

  • Types:

    • Fat-soluble (A, D, E, K)

    • Water-soluble (C, B-complex)

Important Functions

  • B-complex vitamins: convert carbs into glucose

  • Vitamin C: skin, bone, connective tissue formation

Minerals

Functions and Requirements

  • Essential roles in:

    • Healthy bones, teeth, muscles

    • Maintain water balance and nerve functions

  • Electrolytes:

    • Sodium, potassium, chloride for muscle control

Hydration

Importance of Water

  • Most essential nutrient, 60% of body weight

  • Regulates chemical processes

  • Lack of hydration can lead to illness

Fluid Replacement Tips

  • Monitor hydration through urine color

  • Hydrate before, during, and after exercise

Nutrition for Athletes

Nutritional Timing

  • Key times to focus on nutrition:

    • Before competition: High carb diet

    • Pre-game meal planning: 1-4 hours prior

    • Recovery foods: Carbohydrate-rich foods post-exercise

Supplementation

  • Mineral supplementation: Calcium and iron often low

    • May require modification of diet

Weight Management

Weight Loss and Gain

  • Adopting a combination of diet and exercise for effective management

  • Moderate weight loss/gain recommended

Eating Disorders in Athletes

  • Common types: Bulimia and Anorexia Nervosa

  • Early intervention is crucial for recovery

Nutritional Myths

  • Myth: Athletes need to supplement minerals if well nourished

  • Fact: Excess protein doesn’t directly lead to lean mass gain.
