Study Notes

Healthy Eating and Physical Activity Participation

  • Lesson Focus: Understanding the relationship between healthy eating and physical activity.
  • Learning Competencies:
    • Describe how macronutrients are broken down into fuels for physical activity.
    • Relate healthy eating to physical activity participation.
  • Lesson Focus (Continued): Physical activity requires a healthy body. This can be attained by eating foods that are good for you.
  • Essential Nutrients: The body needs macronutrients to function and stay active; these nutrients provide energy.
  • Macronutrients: These nutrients are needed in larger quantities to provide energy. Macro-based diets are categorized into three types. These are:
    • Carbohydrates
    • Proteins
    • Fats

Carbohydrates

  • Energy Source: Carbohydrates are the body's primary energy source, especially during physical activity.
  • Needs by Age Group:
    • Boys (ages 13-14) need 2800 kilocalories while weighing 50 kilos.
    • Girls (ages 13-14) need 2250 kilocalories while weighing 49 kilos.
  • Sources: Carbohydrates can be consumed from starches and sugars.
  • Excess Carbohydrates: Taking in more carbohydrates than the body can use results in stored body fat, which may lead to overweight or obesity, a serious health risk.

Proteins

  • Body Building: Proteins are known as body-building foods. They're necessary for growth and development, and especially for bones and muscles.
  • Repair: Protein-rich food helps the body repair itself.
  • Optimal Intake (By Age Group):
    • Boys (ages 13-15) need 71 grams of protein daily.
    • Girls (ages 13-15) need 63 grams of protein daily.

Fats

  • Body Functions: Fats are nutrients that the body uses to build cell membranes, nerve tissue (including the brain), and hormones.
  • Energy Storage: The body also uses fat as fuel. Fats also allow the body to store energy, cushion organs, and help absorb fat-soluble vitamins.
  • Good Sources: Avocados, nuts, and olive oil are good sources of fats.

Macronutrients and Energy

  • Energy Source: Macronutrients, primarily carbohydrates and fats, are the main sources of calories and energy for the body.
  • Daily Activities: A combination of carbohydrates and fats fuels daily physical activity. Fats are often the primary fuel source for low-intensity exercises.
  • Intense Exercise: As the intensity of exercise increases, the body's need for carbohydrates and fat as energy sources is increased.
  • Hydration is Important: Staying hydrated is crucial throughout physical activity. This includes pre-exercise, during exercise, and post-exercise hydration. Drinking water regularly during activity is important, especially during prolonged or intense periods.
