Types of Resistance Training Flashcards
isometric exercise
static exercise with no movement of joint and no muscle length change
advantages of isometric exercise
no joint movement, so less pain can be used for strength or endurance can produce more tension than concentric less risk of injury continue neuromuscular control
parameters to isometric exercise
6-10 seconds, 60% MVC
contraindications to isometric exercise
cardiovascular disorders/HTN
dynamic exercise
muscle contraction with joint movement
concentric exercise
external force is overcome by muscle contraction causing shortening of muscle
eccentric exercise
overloading of a muscle force-production capacity resulting in controlled lengthening
characteristics of eccentric exercises
increased muscle soreness
increased tendon remodeling
increased microdamage
increased force production
how do you account for the limits of dynamic exercise against constant external resistance
be sure that you are at the appropriate muscle length for maximal tension production when the machine exercise is going to challenge maximally
what is the difference between open chain and closed chain exercises
closed chain is distally fixated
open chain is not fixed distally
advantages of open chain exercises
easier to isolate muscles
greater external stabilization
non-weight bearing
advantages of closed chain exercises
weight bearing, internal muscular stabilization
limited shear can be controlled
coactivation and dynamic stability
good proprioceptve and kinesthetic feedback
balance and postural control
parameters for progressing closed chain exercises
partial to full WB less stable surface sensory deprivation faster uni to multi planar
advantages to manual resistance
control of pt movement
good for early rehab
disadvantages of manual resistance
limit by strength of exercise difficult to quantify non-independent speed is slow may not be functional
