Exercise Metabolism
  • Aerobic: (cardio) low intensity physical activity that lasts a long duration
    • muscles have enough oxygen to produce all the energy they need
    • waste products: carbon dioxide and water.
    • these byproducts are easily expelled through the simple act of breathing.

Anaerobic: high intensity physical activity that lasts less than 2 minutes

    • muscles do not have enough oxygen to create the energy you are demanding from them
    • Byproduct: lactic acid
    • Lactic Threshold: Too much lactic acid will make you slow down
      • Pain, weakness, aching in muscles
      • Uncontrollable breathing
improving cardiorespiratory fitness
Improving Cardiorespiratory Fitness
  • A combination of aerobic and anaerobic exercises are key to improving one’s cardiorespiratory endurance
  • Aerobic Adaptations:
    • Stronger heart
    • More blood
    • More mitochondria
  • Anaerobic Adaptations:
    • Increasing lactic threshold
improving muscular strength and endurance
Improving Muscular Strength and Endurance
  • Mostly achieved via anaerobic exercises
  • More muscles work, stronger they become
    • Achieved through resistance/ strength training
      • Free weights
      • Exercise machines
      • Own body weight
improving flexibility
Improving Flexibility
  • Stretching is the primary way to improve flexibility
    • Yoga
    • Pilates
