Exam 2

the ability to move a specific joint through its full ROM

increase with stretching, decreases with inactivity

able to hold an extended position

ability to move through the joint’s full ROM with little resistance to movement

structure, elasticity and length, and nervous system regulation

hinge has little movement compared to a ball and socket joint

provides strength and stability, limits ROM

lines the bone surfaces

occurs when break down happens

fills the joint cavity to reduce friction and impact

soft tissue limits flexibility; stretching regularly will lengthen the tissue

30%

white fibers: structure and support

yellow fibers: elastic and flexible

temporary lengthening

long term change in length

-proprioceptors detect the amount of change and the speed of the change in length and cause a muscle contraction to resist the change - a second signal is sent to the brain to the antagonist of the muscle, causing it to relax

combined with flexibility reduces the risk of injury

• aids joint health • prevents low back pain • relieves aches and pains • relieves muscle cramps • improves body positioning • posture and balance • relaxing and reduces tension • improves mobility after injury

sit and reach test

goal is to attain normal flexibility in all major joints, should be balanced, perform stretches on a regular basis

2-3 days a week

stretch to the point of tension

hold 10-30 secs, 30-50 seconds in between
