Flashcards › Ch 6 - Flexibility Training Concepts

Normal extensibility of all soft tissues that allow full range of motion around a joint Flexibility Ability of neuromuscular system to allow agonists, antagonists and stabilizers to work synergistically to produce, reduce and dynamically stabilize the entire kinetic chain in all three planes of motion Neuromuscular efficiency Multiplanar soft tissue extensibility with optimal neuromuscular efficiency throughout the full range of motion Dynamic functional flexibility The latissimus dorsi must have proper extensibility in the sagittal plane to allow for proper shoulder flexion The gastrocnemius must have propler extensibilty in the sagittal plane to allow for proper dorsiflexion of ankle Predictable patterns of muscle imbalances Postural distortion patterns Tendency of body to seek the path of least resistance during functional movement patterns Relative flexibility Alteration of muscle length surrounding a joint Muscle imbalance Muscle inhibition caused by a tight agonist which inhibits its functional antagonist Altered reciprocal inhibition Occurs when inappropriate muscles take over the function of a weak or inhibited prime mover Synergistic dominance The motions of joints in the body Arthrokinematics Altered forces at the join that result in abnormal muscular activity and impaired neuromuscular communication at the joint Arthrokinetic dysfunction Sensory organ alongside muscle fiber sensitive to change in length and rate of length change Muscle spindles Sensory organs sensitive to changes in muscular tension and rate of tension change Golgi tendon organs Process when neural impulses that sense tension is greater than impulses that cause muscles to contract, inhibiting muscle spindles Autogenic inhibition Consistently repeating the same pattern of motion, which may place abnormal stress on the body Pattern overload States that soft tissue models along the lines of stress Davis's law Dysfunction is treated by the body as an injury and will initiate a repair process called the Cumulative injury cycle Designed to improve muscle imbalances and altered joint motion Corrective flexibility Designed to improve extensibility of soft tissue and increase neuromuscular efficiency by using reciprocal inhibition Active flexibility Integrated, multiplanar soft tissue extensibility, with optimal neuromuscular control, through full range of motion Functional flexibility Suring SMR, sustain pressure for a minimum of 20 to 30 seconds The result of Self-Myofascial Release is increased golgi tendon orgnan activity and decreased muscle spindle activity Passively taking a muscle to the point of tension and holding the stretch for a minimum of 20 seconds Static stretching Using agonists and synergists to dynamically move the joint into a range of motion Active-isolated stretch Acute variables for active-isolated stretching 1-2 sets, hold each stretch 1-2 seconds, 5-10 repetitions Acute variables for dynamic stretching 1 set, 10 reps, 3-10 exercises NASM Ch 6
