Exercise Technique and Training Instruction Flashcards
Force-couple relationships
The synergistic action of multiple muscles working together to produce movement around a joint.
Reciprocal inhibition
When an agonist receives a signal to contract, its functional antagonist also receives an inhibitory signal allowing it to lengthen.
Altered reciprocal inhibition
Occurs when an overactive agonist muscle decreases the neural drive to its functional antagonist.
Synergistic dominance
The neuromuscular phenomenon that occurs when synergists take over function for a weak or inhibited prime mover (agonist).
Altered length-tension relationship
When a muscle’s resting length is too short or too long, reducing the amount of force it can produce.
Muscle spindle
Sensory receptors sensitive to change in LENGTH of the muscle and the rate of that change.
Golgi tendon organ (GTO)
A specialized sensory receptor located at the point where skeletal
muscle fibers insert into the tendons of skeletal muscle; sensitive to changes in muscular TENSION and rate of tension change.
Autogenic inhibition
The process by which neural impulses that sense tension are greater than the impulses that cause muscles to contract, providing an inhibitory effect to the muscle spindles.
What do Hip flexor, adductor, and latissimus dorsi static and active stretches do?
Posteriorly rotate the pelvis to increase the effectiveness of the stretch.
What are the Cable rotation, Cable lift exercises extension
Make sure to pivot the back leg into triple extension:
Hip extension
Knee extension
Ankle plantarflexion (extension)
Lower-body progressions
• Two-legs/stable (e.g., standing on the floor)
• Wide stance → Narrow stance →
Tandem stance (heel-to-toe)
• Single-leg/stable (e.g., standing one-legged on the floor)
• Two-legs/unstable (e.g., standing two-legged on a balance modality)
• Single-leg/unstable (e.g., standing one-legged on a balance modality)
