  1. Improving Fitness Levels Mr. DiCicco

  2. 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.

  3. 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

  4. 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

  5. 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

  6. Improving Flexibility • Stretching is the primary way to improve flexibility • Yoga • Pilates
