Strengthening Exercise Flashcards

1
Q

Principles of strengthening.

A

Overload (the muscle will work maximally if maximally loaded).
Signs- fatigue, difficulty carrying out exercise, quivering muscle belly, grimacing face, discomfort.
Strength- high weight/ load and low reps
Endurance - low weight and high reps
Reversibility
Specific adaptation to imposed demand S.A.I.D
Baseline

Q

How to enable progression?

A

Needed for strengthening. Includes..

  1. Increase weight, reps, sets, frequency
  2. Increase friction
  3. Reduce speed
  4. Increase length lever/ moment arm
  5. Change starting posistion/ use gravity
  6. Change type of contraction
  7. Change range of contraction- most efficient in middle range (cross bridges) for early exercise

Q

What percentage of 1 repetition max, what does it do and how many reps on average and is is it inapproprate?

A

60-80%
Induce muscle fatigue, not exhaustion,
8-12 reps
Inappropriate for early rehab due to pain and reinjury risk

Q

Benefits of strengthening exercises?

A
  1. Increase tensile strength of tendons/ligaments
  2. Increase bone density/remodeling
  3. Increse hypertrophy of muscle fibres
  4. Increase hyperplasia of muscle fibres
  5. Increase rate of motor units firing
  6. Increaw synchronisation of motor units
  7. Increase dorce generation capacity
  8. Increase ATP and creatine prosphate storage
