Proprioception – ANSWER 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 – ANSWER specialized structures that recognize pressure in tissue and transmit signals to sensory nerves. Muscle Spindles – ANSWER 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 – ANSWER 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 – ANSWER connective tissue UNDER fascia that acts as an outer layer of the whole muscle Perimysium – ANSWER connective tissue acts as an outer layer of fascicles Endomysium – ANSWER between the individual muscle fibers Type 1 Muscle Fiber – ANSWER "slow-twitch", smaller in size, lessforce produced, long-term contractions (stabilization) Type 2 Muscle Fiber – ANSWER fast twitch, larger, quick to fatigue, force and power exercises Agonist – ANSWER PRIME MOVER, main muscles ex: chest press-> pectoralis major Synergist – ANSWER ASSIST PRIME MOVER, ex: chest press -> ant deltoid, triceps Stabilizer – ANSWER stabilizes while prime mover and assist work. chest press -> rotator cuff Antagonist – ANSWER Oppose Prime mover, chest press -> posterior delt Right Atrium – ANSWER gather DEOXGENATED blood returning to the heart from ENTIRE BODY Left Atrium – ANSWER gathers OXYGENATED blood coming from the LUNGS Right Ventricle – ANSWER thin walls pumps under low pressure. Pumps to lungs Left Ventricle – ANSWER thick walls, pumps under high pressure to rest of body Metabolism – ANSWER all of the chemical reactions that happen in our body to maintain itself. Nutrients are acquired, transported and used by the body. Exercise Metabolism – ANSWER bioenergetics as it relates to the unique physiologic changes and demands on body during exercise Substrates – ANSWER where enzymes act Carbohydrates – ANSWER Sugars, starches, and fiber. Provide the body with a source of fuel and energy required for all daily activities Glucose – ANSWER a simple sugar that comes from the digestion of carbs that is transported through the blood and is used or stored as energy Glycogen – ANSWER the stored form of carbs, when needed it converts to glucose and used Fat – ANSWER a secondary source of energy Trigylcerides – ANSWER come from fats, when calories are consumed but not used they are converted and stored in fat cells Protein – ANSWER Amino acids that build and repair body tissues and structures. A third energy source, usually not until starvation. Recommended 0.8 g per day Adults, 1.2-1.7 per day strength athletes, 1.2-1.4 endurance athletes 1 g = 4 calories Gluconeogenesis – ANSWER glucose form from non-carb sources like amino acids Adenosine Triphosphate (ATP) – ANSWER Energy storage and transfer unit in the cells. When chemical bonds that hold it together are broken, energy is released Adenosine Diphosphate (ADP) – ANSWER molecule produced by ATP ATP-PC system – ANSWER simplest and fastest, occurs without oxygen (anaerobic), provides energy for high intensity, short-duration ex: power and strength Glycoses System – ANSWER produces lots of energy for 30-50 sec. Typical bc it falls in the time frame of 8-12 reps Oxidative System – ANSWER most complex B- oxidation – ANSWER breakdowns triclgycerides into free fatty acids to produce more ATP Myth of Fat Burning Zone – ANSWER higher intensity workouts require greater contribution from fat despite the increase in need of fuel source from carbs Biomechanics –
