NSCA CSCS - Chapter 14 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
Hold-relax
PNF stretching technique involving isometric contraction of the muscle being stretched to cause autogenic inhibition and subsequent relaxation
Hold-relax with agonist contraction
PNF stretching technique involving isometric contraction of the muscle being stretched to cause autogenic inhibition, followed by concentric action of the opposing muscle to facilitate reciprocal inhibition
Mechanoreceptor
Proprioceptors that respond to increases in tension or length
Mobility drills
Dynamic stretching activities that use general and sport-specific movements to prepare the body for activity
Muscle spindles
Specialized muscle fibers running parallel to normal extrafusal fibers that activate when a muscle is rapidly stretched
Passive stretch
A stretching technique where external force such as a partner or machine provides the force for stretching
Plasticity
The tendency of joint and muscle tissue to return to assume new and greater length after passive stretching
Potentiation
Sport-specific warmup that focuses on increasing intensity of sporting movements until intensity matches desired practice or competition level
Proprioceptive neuromuscular facilitation
Category of stretching techniques involving a partner and active isometric and concentric muscle action to utilize autogenic and reciprocal inhibition for increase range of motion and stretch effectiveness
Raise, activate, mobilize, and potentiate (RAMP)
A warm-up routine designed by a coach incorporating sport-specific skills and movements to prepare the athlete for training or competition
Range of motion (ROM)
The degree of movement that occurs at a joint
Reciprocal inhibition
Relaxation that occurs in the antagonist muscle to the muscle experiencing tension (i.e. hamstrings relaxing during quad contraction)
Specific warm-up
Second component of warm-up that Incorporates movements similar to the movements of the athlete’s sport and should include rehearsal of the skills to be performed
Static flexibility
The range of possible movement around a joint during passive movement - force for stretch is provided by an external source (i.e. partner, machine)
Static stretch
A slow stretch where the end position is held for 15 to 30 seconds - includes relaxation and concurrent elongation of the stretch muscle
Stretch reflex
When the muscle spindle stimulates a motor neuron causes a muscle contraction in the extrafusal muscle fibers associated with the muscle spindle
