8th Grade Fitness Concepts


Physical Fitness Components:

Cardiorespiratory Endurance

Muscular Strength

Muscular Endurance

Muscular Flexibility

Body Composition


Muscular Strength

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


Benefits to Muscular Fitness

  • Boost self-confidence and body image

  • Increased reaction time

  • Increased speed

  • Greater bone density

It’s an investment!


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


Muscular Endurance

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


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


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.)


Isotonic Exercise

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


Isometric Exercise

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


Progression

  • increasing the workload in exercise as the body adapts.

Week 4 workload

Week 3 workload

Week 2 workload

Week 1 workload


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


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.
