Resistance training Flashcards
3 types??
isotonic
isometric
isokinetic
isotonic
can see muscle contraction
- using eccentric and/or concentric
- open or closed
helps to keep strength, power and endurance
- increase circulation, good CV, HYPERTROPHY BABYYYY
keeps elasticity
- helps joint motion and increase coordination
isometric
no sig. joint motion or change in length of muscles
- w/ or w/o outside resistance
- helps to avoid pain w/ joint motion but still want to be stronk
- activate muscle w/ weak muscle
isokinetic
specific equipment
- controls speed of contraction
- creates resistance thru arc or ROM
resistance ex.
exer. where dynamic or static muscle contraction is resisted by outside force (manual or mechanical)
constant resistance - muscle will adapt and become stronger over time
- very important in pt. POC
mechanical resistance
applied thru machines
can measure how much resistance and increase slowly
- helps PT to increase gradually
goals of resistance ex.
overall = improve function
specific:
- increase strength, endurance and power
strength
force output of muscle
direct relation to amount of tension
strength training
working out dif. muscles
controlling loads for low reps or short time
increase muscle fiber size
endurance
low intensity rep over long time
ability to create and keep tension to resist tiring
- no correlation always with strength
power
work per unit of time - the rate of performing work
either one burst of HIT or lots of less intense actions
greater intensity and short time = greater power
overload principles
the goal - challenge muscle to go out of comfort zone
- changing weight or reps
strength - change resistance
endurance - reps/sets
contraindications to resistance
pain
- need to know where it is
inflammation
- can be in joint or muscle damage
- low isometric can be indicated if no increase pain or signs of inflame
severe cardiopulmonary disease
- avoid 12 weeks post CABG
precautions
avoid valsava
- can increase arterial BP due to holding breath
avoid substitute motion
- parts of the body can become painful
determinants
alignment
stable
intensity
volume
order
freq
rest
duration
mode
velocity
periodization
integration into functional activities
