  1. 1. + Chapter 2 Learning Skills for Enjoying Physical Activity
  2. 2. + Vocabulary  Agility  Balance  Coordination  Motor Skills  Motor Units  Performance Skills  Power  Practice  Reaction Time  Skill  Skill-Related Fitness  Speed  Sport skills
  3. 3. + Skill  Ability to do a specific Task
  4. 4. + What are skills?  Sport Skills: Skills needed to perform vigorous activities such as sports.  Motor Skills: Skills that are needed to move but not necessarily for vigorous activities such as sports.  Motor Units: when nerves and muscles work together as they are signaled by the brain.  Performance Skills: Skills used in activities other than sports.
  5. 5. + Practice  We learn skills with PRACTICE and are able to function effectively.  The younger you are, the easier you may learn skills.  Basic skills and sport skills are learned in elementary and middle school.
  6. 6. + Parts of Skill-Related Physical Fitness  AGILITY  The ability to change body positions quickly and keep your body under control when it is moving.  Rope Games, Dancing, Wrestling, and defending in football and basketball.
  7. 7. + Parts of Skill-Related Physical Fitness  BALANCE  The ability to keep your body in a steady position while standing or moving.  Balance helps you to ride a surfboard, ride a bike, and do activities such as the balance beam in gymnastics.
  8. 8. + Parts of Skill-Related Physical Fitness  COORDINATION  The ability of body parts to work together when you perform an activity. Hitting a ball requires the use of your eyes together with your hands and arms.  Jumping hurdles, kickboxing, and aerobic dance require your eyes, feet, and legs. Kicking and performing dance steps require coordination.
  9. 9. + Parts of Skill-Related Physical Fitness  POWER  The ability to combine strength with speed while moving. A shot putter combines strength with speed to perform with power.  A softball player who swings the bat quickly and with a lot of force demonstrates power.
  10. 10. + Parts of Skill-Related Physical Fitness  REACTION TIME  The ability to move quickly when you get a signal to start moving.  A swimmer or runner starting a race needs good reaction time.
  11. 11. + Parts of Skill-Related Physical Fitness  SPEED  The ability to get from one place to another in the shortest possible time.  You can have speed of your whole body, such as when you move your hands very quickly to steal a ball from another person in a basketball game.
  12. 12. + Moving Together: Full Participation  WHENYOU ARE A LEADER OF A GROUP  Use basic leadership skills  Strong Voice  Eye Contact  Enthusiasm  Ask questions of the group  Ask group members to help demonstrate skills  Have all group members practice the skills together  Give positive feedback to those who try  Tell group members that it is OK to make a mistake
  13. 13. + Moving Together: Full Participation  WHENYOU ARE PARTICIPATING IN A GROUP  Help the leader by participating.  Avoid talking when the leader is talking.  Give your best effort in all activities.
  14. 14. + Vocabulary  Feedback  First-Class Levers  Lever  Mental Practice  Paralysis by analysis  Practice  Routine  Second-Class levers  Third-Class levers
  15. 15. + What is practice?  Repeating an action over and over to improve skill.
  16. 16. + What is feedback?  Information that the instructor “feeds” or gives “back”to you after you perform a movement so you have a better idea of what you did.  Helps you to make appropriate changes so that you improve your performance.
  17. 17. + Biomechanical Principles: Levers  LEVER: Basic machine. A bar or stiff straight object that can be used to lift weight, increase force, or create speed.
  18. 18. + Biomechanical Principles: Levers  FIRST-CLASS LEVERS: Allow you to lift a heavy weight with a small amount of force. Ex:Whole body weight with the small leg muscles.
  19. 19. + Biomechanical Principles: Levers  SECOND-CLASS LEVERS: Not common. Person doing a push-up. Force required for the arms to lift the body is about half the total body weight.
  20. 20. + Biomechanical Principles: Levers  THIRD-CLASS LEVERS: Most common. Pivot point at the end. Muscles apply force to the lever near the pivot.
  21. 21. + Principle in Practice  Practice helps you use your body levers properly  Practice helps you improve speed  Practice helps you improve accuracy
  22. 22. + Paralysis by Analysis  Too much information given at one time
  23. 23. + Mental Practice  Imagining performing a skill properly.
  24. 24. + How often should you practice?  Works best when you enjoy it and can focus on it.  Too long practices can get you tired or bored.  Find ways to make practice fun or use enjoyable practice drills.  Regular practices are necessary: Longer for athletes. Daily practice is best.  If you don’t practice, your body “forgets” the best way to perform skills.
