1. Why do Humans Need Exercise? Physical activity to keep body working it’s best No longer getting in daily hard work as we have evolved over time. No longer hunting for food for survival Industrial revolution…

2. Benefits of Exercise Increase muscle strength & endurance Alertness and Increased energy level Heart works more efficiently Decrease risk for heart attack, stroke, cancer Makes bones stronger Control blood pressure (BP) & Cholesterol Weight control Improve sleep Improve skill performance (basketball, football, volleyball, etc) Reduce stress, release endorphins (makes you feel good), less moody Improved appearance And many more, but you are starting to get the idea…..

3. Aerobic Exercise (for life) DefineExamplesBenefitsCharacteristics -Requires Oxygen to the muscle for a long period of time -Uses oxygen over an extended period of time Uses fats and carbohydrates for fuel and is the main source of energy for activities lasting more than two minutes. Also called “cardio” because heart pumps lots of blood/oxygen to muscles for a long time and strengthens heart -Biking -Swimming -Jogging -Aerobic Dance -Power Walking -Rowing -Basketball - Improved Endurance of heart and lungs -Weight loss -Lower blood pressure & heart rate Strengthens muscles used to breathe (respiratory system) Increases oxygen delivered to your body’s cells -Stronger heart -Engery/Alertness -Disease prevention – 1.cancer 2.diabetes 3.cardiovascular Involves large muscles of arms and legs Rhythmical pattern (biking, swimming, same motion over and over) Done continuously for at least 30 mins Intense enough for breathing and heart rate to increase,

4. Anaerobic Exercise DefineExamplesBenefitsCharacteristics Uses up Oxygen that is stored fast, so muscles can’t do the work a long time Where oxygen can’t be delivered fast enough to the muscles. It uses energy stored in the cells for fuel. Main energy source for activities that are a short time such as a 100 meter sprint -Some weight training (power lifting) -Track – short distance, sprinting -Gymnastics -short swim races -High jump -Improved agility -Improved reaction time -Improved strength -Improved power -Improved speed -Improved endurance Anaerobic exercise helps all these areas -Fast intense bursts of activity -Activities that you can’t do for long periods of time
