Golgi tendon
musculotendonous junction that detects tension applied to tendon during slow static stretch.
Cardio Output
amount of blood pumped
... [Show More] out by each side of the heart in 1 min.
Davie's Law
soft tissue models along the lines of stress.
Reciprocal inhibition
muscles on one side of a joint relaxing to accommodate contraction on the other side of that joint.
Agonist Muscle
the muscle that contracts to produce a movement; prime mover.
Antagonist Muscle
the muscle that has an action opposite to that of the agonist and helps in the production of a coordinated movement.
Prime Mover
the muscle that acts as the initial and main source of motive power.
Static Stretching
a technique in which a muscle is slowly and gently stretched and then held in the stretched position.
Autogenic Inhibition
the process when neural impulses that sense tension is greater than the impulses that cause muscles to contract, providing an inhibitory effect to the muscle spindles.
Force Couple Relationship
muscle groups moving together to produce movement around a joint; muscles in a force-couple provide divergent pulls on the bone or bones they connect with which is a result of the fact that each muscle has different attachment sites, pulls at a different angle, and create a different force on that joint.
Oxidative System
relies primarily on carbohydrates and fats for the production of ATP. This system is the slowest producing of the three systems because it requires increased amounts of O2 to match the muscular requirement of the exercise. O2 must be supplied through respiration, and it takes a while to elevate the respiration rate to consume appropriate amounts of O2. Needless to say, even though this system is the slowest producing, it results in the greatest amount of ATP.
ATP-PC
phosphocreatine breakdown (occurs in cytoplasm), anaerobic pathway, immediately available, provides ATP for 10 secs, quick bursts of energy.
Acetylcholine
a neurotransmitter that enables learning and memory and also triggers muscle contraction.
Arthrokinematics
the motions of the joints in the body; joint motion.
Synergistic Dominance
the body's substitution system when there is a weak or inhibited prime mover
Sarcomere
the functional unit of muscle that produces muscular contraction and consists of repeating sections of actin and myosin.
Sarcoplasm
cell components that contain glycogen, fats, minerals, and oxygen that are contained within the sarcolemma.
Sarcolemma
a plasma membrane that surrounds muscle fibers.
Gastrocnemius
Calf muscle that causes plantaflexion e.g. [Show Less]
