Chapter 14 - Warm-Up and Flexibility Training Flashcards
Active stretch
A stretching technique where the person stretching supplies the force for the stretch.
Agonist contraction
Contracting an opposing muscle to a targeted muscle in a stretch to cause reciprocal inhibition in the stretched muscle
Autogenic inhibition
Relaxation that occurs due to GTO activation in a muscle experiencing tension
Ball-and-socket joint
Joints such as the shoulder and hip that allow movement in all three planes
Ballistic stretch
Stretch involving active muscular action using a bouncing type movement in which the end position is not held - can cause injuries if not appropriately controlled or sequenced
Contract-relax
PNF stretching technique involving isometric contraction of the targeted muscle to cause autogenic inhibition
Dynamic flexibility
The available ROM during active movements requiring voluntary muscle actions
Dynamic stretch
A functionally based stretching exercise that uses sport-generic and sport-specific movements to prepare the body for activity
Elasticity
The ability of joint and muscle tissue to return to resting length after a passive stretch
Ellipsoidal joint
Joints that have an oval-shaped condyle that fits into an elliptical cavity that primarily allows sagittal and frontal plane movement
Fibrosis
Process of fibrous connective tissue replacing degenerating muscle fibers
Flexibility
The relative ability to move a joint through a range of motion
General warm-up
First phase of warm-up that generally consists of light aerobic exercise and stretching
Golgi tendon organ (GTO)
Mechanoreceptors located near the musculotendinous junction that are sensitive to increases in tension
Hinge joint
Joints such as the knee that primarily move in the sagittal plane
