H.228 Exam 2: Flexibility Flashcards

range of motion (ROM) of a joint of group of joints, as per the skeletal muscles and not any external forces

a joint’s ability to move through its full range of motion

CT between bones, thereby protecting the joint from excessive mvt

= covers the ends of articular/joint surfaces of bones

• = the principal protein of in the body accounting for around 30% of all proteins
• type I
• type II

consists of thick fibers that elongate very little when placed under tension, relatively stiff and strong

fibers that are much thinner than type I and possess slightly less tensile strength → framework to maintain general shape and consistency

• = non-contractile fibrous CT connecting ends of muscle to one or more bones
• cord-like (tendon) OR sheet-like (aponeurosis)

high stresses, but tissue can return to the original framework

veryhigh stresses you have tissue deformation

tissues fail under stresses and strain

plantar fascia & IT band need 2K of force to deform it 1%

• innervated by alpha motor N to produce force

• → GTOs = do measurements by sensing the static length of extra-fibers and rate of change of length of the muscle
  • sensory component → transmit info
  • motor component → keeps spindle tight to be sensitive to changes in length

• = the degree to which a joint can be moved through available ROM completely dependent on assistance

• = the degree to which a joint can be moved through available ROM with external assistance and muscle contraction

• the degree to which a joint can be moved through available ROM under the participant’s own power

• the degree to which a joint can be moved while engaging the musculature of the joint with resistive forces

= isolating and moving a muscle to its end ROM, gradually, and holding for a certain time

= involves a progressive increase in reach and ROM as the movt is repeated

= static stretching starting slow allowing the tissue to relax into stretch before pushing more

= continuous bouncing mvt at end ROM to try to get MAXlength out of muscle, usually athletes

→ light to moderate discomfort

→ around a min. total each

→ depends on type of stretch

→ how many sets/day per week

→ what type

→ seated, standing, side-lying, supine, prone

→ are joints & limbs/body position is correct for desired stretch

high stresses, but tissue can return to original framework

such high stresses you have tissue deformation

tissue fails under stresses and strain

stiffness (modulus)
