Health Related Components of Fitness

• Muscular Endurance
• Cardio Respiratory Endurance
• Flexibility
• Body Composition

5
Principles of Exercise Training
6
Principles of Exercise Training

• Progression
• start training at level appropriate for initial
  fitness assessment
• gradually increase as body adapts to the training
• Regularity
• train often enough for your body to adapt
• Overload
• train at levels that exceed normal demands
  (intensity and/or time) that you place on your
  body

7
Principles of Exercise Training

• Variety
• equipment, exercises activities
• avoid boredom, increase motivation (adherence),
  reduce risk of overuse injuries
• Recovery
• optimal time for sleep and reduced activity
• heal from stress of training (rebuilding tissue,
  replenishing stored energy)
• Realism
• training plans and goals must make sense given
  time and resources available
• failing hurts motivation and adherence

8
Principles of Exercise Training

• Balance
• between all 5 components (F, CR, MS, ME BC)
• between push and pull movements at each joint
• between upper-body and lower-body
• Specificity
• training demands must emphasize exact areas of
  desired improvement
• movement velocity and patterns, muscle groups,
  energy systems, ranges of motion

9
Functional Anatomy
10
Why is it important?

• Understand how to help a client?
• Professional discussion and assistance
• Personal improvement?
• Meet which principle of exercise?

11
Muscle Anatomy

• If your client want to improve his/her pushing
  strength, which muscles does she or he needs to
  work?
• How about pulling muscles?
• How about lifting strength?

12
What kind of contraction is this one?

Case Study 1

• You are supervising on a training area when you
  hear a lot of clanging noise coming from the
  vicinity of the seated leg press. You see that
  the exerciser at the machines is not controlling
  the descent of the weights. You asks him to
  slowly return the weights down rather than
  letting them go. He asks you whywhat would you
  respond?

15
Case Study 2

• Alice wants to know why she can move a heavier
  weight when she does wrist curls with her palms
  up than with her palms down and why she can do
  more pull ups with her palm facing her than with
  her palm facing away. How would answer her?

16
General Question

• Based on the knowledge you have acquired about
  the way the muscles work, what kind of muscular
  strength training would you said would be must
  effective?

Lab Work/Exercise for this Week
18
Lab Intro-1

• A Self Test
• Complete the entire questionnaire as per
  instructions
• Evaluate your health related behaviors
• Type into Word and turn in by Tuesday.

19
Lab 2-1 PAR-Q

• Questionnaire to identify your readiness to start
  a new program
• Each one of your clients should have a
  questionnaire like this on day one.
• Take the questions seriously, as starting a new
  program could be challenging without the proper
  screening
• Type into Word and turn in by Tuesday.
