  1. 8th Grade Fitness Concepts

  2. Physical Fitness Components: Cardiorespiratory Endurance Muscular Strength Muscular Endurance Muscular Flexibility Body Composition

  3. Muscular Strength • the ability of muscles to exert maximal strength at one time.

  4. Benefits to Muscular Fitness • Boost self-confidence and body image • Increased reaction time • Increased speed • Greater bone density It’s an investment!

  5. Personal Training for Muscular Endurance vs. Muscular Strength Muscular Endurance Muscular Strength Use heavier resistance Do less repetition(8-12) Use explosive movements nearly completing the range of motion(don’t lock out joints at the end of the repetition) • Use lighter resistance • Do high repetitions(15-20) • Use deliberate movement focusing on proper technique

  6. Muscular Endurance • the ability to use muscles for a long period of time.

  7. Body Composition- relative percentage of fat and lean tissue to total body weight.

  8. F.I.T.T. Principle Frequency – How many times per week one does an exercise (Is the workout done 3 times per week?) Intensity- the amount of effortput into an exercise or exercise session. Time- How long was the exercise or exercise session? (10 minutes or 30 minutes) Type- What type of exercise was being completed (push ups, curl ups, jogging, etc.)

  9. Isotonic Exercise • Exercise in which the muscles contract and cause body parts to move.

  10. Isometric Exercise • Exercise in which muscles contract but body parts do not move

  11. Progression • increasing the workload in exercise as the body adapts. Week 4 workload Week 3 workload Week 2 workload Week 1 workload

  12. How does overload relate to muscular strength and endurance? By making your body work hard in the following ways: • Exercising more frequently • Exercising more intensely • Exercising more at one time

  13. Specificity as it relates to muscular strength and endurance Choosing the right exercise for your personal conditioning goals. An example would be: lifting weights with arms to make arms stronger.
