Proprioception - The body's ability to to sense the relative position of adjacent parts of the body Ex: when walking our feet give us proprioception about the type of surface we are on. Mechanoreceptors - specialized structures that recognize pressure in tissue and transmit signals to sensory nerves. Muscle Spindles - sensory receptors in the muscles that are parallel to the muscle fibers and are sensitive to change in muscle length. Spindles stretch with muscle and sends information to CNS. helps to prevent muscles from stretching too far or too fast Golgi Tendon Organs - sensory receptors that are located at the point where the skeletal muscle fibers insert into the tendon. Sensitive to change in tension at the rate of change causes the muscle to relax Epimysium - connective tissue UNDER fascia that acts as an outer layer of the whole muscle Perimysium - connective tissue acts as an outer layer of fascicles Endomysium - between the individual muscle fibers Type 1 Muscle Fiber - "slow-twitch", smaller in size, lessforce produced, long-term contractions (stabilization) Type 2 Muscle Fiber - fast twitch, larger, quick to fatigue, force and power exercisesAgonist - PRIME MOVER, main muscles ex: chest press-> pectoralis major Synergist - ASSIST PRIME MOVER, ex: chest press -> ant deltoid, triceps Stabilizer - stabilizes while prime mover and assist work. chest press -> rotator cuff Antagonist - Oppose Prime mover, chest press -> posterior delt Right Atrium - gather DEOXGENATED blood returning to the heart from ENTIRE BODY Left Atrium - gathers OXYGENATED blood coming from the LUNGS Right Ventricle - thin walls pumps under low pressure. Pumps to lungs Left Ventricle - thick walls, pumps under high pressure to rest of body Metabolism - all of the chemical reactions that happen in our body to maintain itself. Nutrients are acquired, transported and used by the body. Exercise Metabolism - bioenergetics as it relates to the unique physiologic changes and demands on body during exercise Substrates - where enzymes actCarbohydrates - Sugars, starches, and fiber. Provide the body with a source of fuel and energy required for all daily activities
