What are the four steps in "Bridging the Gap" between current client health & fitness levels, & their future goals & needs? correct answer: Assess - Design - Instruct - Re-assess What is the difference between implicit & explicit goals? correct answer: Implicit - implied, but not necessarily mentioned. Explicit - goals that are mentioned by your client. What is the kinetic chain? What is its function? correct answer: 3 separate systems which work together to create human movement. (nerous system, muscular system, skeletal system) What is the difference between smooth, cardiac & skeletal muscle? correct answer: Smooth - muscles that are capable of involuntary actions/no striations. (digestive tract, bladder, uterus, blood vessel walls) Cardiac - muscles that are capable of involuntary actions/some striations. (heart only) Skeletal - muscles that are capable of voluntary contraction. (all muscles controlling movement) What are the 3 layers of fascia? What is their significance? correct answer: Epimysium - outer layer/surrounds muscle completely. Perimysium - next layer/groups muscle fibers in bundles. Endomysium - innermost layer/surrounds individual muscle fibers. What is the structure of the motor unit? correct answer: A motor neuron & all of the fibers it activates. What is the sliding filament theory? correct answer: The Sacromere is composed of thin & thick filaments, these elements slide over each other resulting in the shortening of all the sacromeres together causing the muscle to contract. Know the difference between eccentric, isometric & concentric muscle actions. Which is the strongest? Which is the weakest? correct answer: Eccentric - as the muscles attempt to control the downward phase or decelerate load. (the strongest) Concentric - as the muscles attempt the contraction or lifting phase of a load. (weakest) Isometric - static/the muscle fires, but there is no change in the length of the muscle & no movement in the joints. What is the difference between hypertrophy, hyper
