Arrhythmia - ANSWER Abnormal electrical impulses. Atrial fibrillation means blood does not fully leave left atrium. Ventricular fibrillation is more serious Hyperventilation - ANSWER Rapid/deep breathing Angina pectoris - ANSWER Result of myocardial ischemia cause by an imbalance between myocardial blood supply and oxygen demand Myocardial infarction - ANSWER BLood flow to part of heart is blocked Myocardial ischemia - ANSWER Lack of blood flow and oxygen ot heart Stroke - ANSWER Blood flow to a part of the brain stops Hypertension - ANSWER High BP Hyperlipidemia - ANSWER High concentration of lipids in blood Peripheral pulses - ANSWER Carotid and Radial artery Types of stretches - ANSWER Ballistic: Repetitive bouncing, not ideal Dynamic: smooth movements gradually increasing ROM Active: Agonist muscle is working Static: Hold position at furthest ROM PNF: Contract-relax Plyometric: Maximize stretch-reflex of muscles Risk factors favorably modified by PA - ANSWER Hypertension Cholesterol High blood sugar Lack of PA Obesity Cardiorespiratory fitness - ANSWER Measure of how well your heart, arteries, veins, and lungs work together to transport oxygen to muscles. Then how well oxygen is absorbed and used in your muscles (based on capillary distribution at muscles and mitochondrial density-responsible for aerobic ATP synthesis) Body Composition - ANSWER Reveals the relative proportions of fat and lean mass in the body. Men 10-22%, Women 20-32% Skinfold, BIA, BODPOD, Hydrodensity Flexibility - ANSWER Limits of the muscuoskeletal unit Proprioceptors: the capacity of the neuromuscular system to inhibit the antagonists influences flexibility
Muscle spindles - ANSWER Respond to change in length Intrafusal fibers run parallel to extrafusal fibers Stretch reflex - ANSWER When a muscle spindle is stretched, the muscle spindles cause a reflex of the muscle Golgi tendon organ - ANSWER Monitors tension in muscle Stimulation results in relaxation of muscle Muscular strength - ANSWER Force of an external load on muscles. First neurological adaptation then muscle hypertrophy Hypertrophy versus hyperplasia of muscle - ANSWER Muscle endurance - ANSWER Low weight high reps. Avoid valsalva Type IIa fibers Absolute contraindication versus relative contraindication - ANSWER Stress test should not be performed until condition is stabilized. May be tested only after careful evaluation of risk/benefit ration Absolute contraindication list - ANSWER 1. EKG change suggest recent MI, severe ischemia, or other significant cardiac event
