ACSM Certified Exercise Physiologist Exam 2022 Fully Verified. Physical Activity >>>>Any bodily movement produced by contracting skeletal muscles, with an increase in energy expenditure. Exercise >>>>Planned, purposeful, repetitive Physical Fitness >>>>Attributes or characteristics that individuals have achieved that related to their ability to perform physical activity 3 metabolic pathways the body uses to creates ATP >>>>1. Creatine Phosphate 2. anaerobic glycolysis 3. 0xidative system Claudication >>>>pain in the leg is induced by exercise, usually because of an artery obstruction. Creatine Phosphate system >>>>Small amounts of CP are stored within each cell. Simple one-to-one trade off that allows for the rapid production of ATP. ONLY for use during short bouts of exercise. less that 10 seconds. Anaerobic glycolysis >>>>No oxygen required. NExt most immediate energy source. break down carbs (glucose or glycogen) into pyruvate. Used during medium-duration exercise. no more than about 90 seconds. Aerobic glycolysis (oxidative system) >>>>Oxygen dependent. As exercise intensity decreases allowing for longer duration activities, use of the oxidative system increases. (Krebs cycle and ETC). Produce ATP in the mitochondria of the cell--requires oxygen. Lasts longer than 1-2 minutes. What is VO2? >>>>The volume of oxygen the body consumes. VO2 max is the highest volume of oxygen the body can consume. Define Stroke Volume >>>>the volume of blood the heart ejects with each beat. How does SV increase with workload? >>>>Similar to HR, it increases as workload increases but only up to ~40% to 60% of VO2max. The percentages can be decreases in sedentary individuals and increased with training. What happens to resting HR as stroke volume increases? >>>>it decreases, as more blood being pumped per beat allows the heart to beat less often. What is cardiac output? >>>>a measure of blood pumped per minute. The product of stroke volume and heart rate. What does Diastolic Blood pressure do during exercise? >>>>Remains stable or decreases slightly. What is rate pressure product? >>>>serves as an estimate of myocardial oxygen demand. Product of HR and Systolic BP. HR X SBP What is the Fick equation used to determine VO2 max? >>>>VO2max = HRmax X SVmax X a-VO2 difference max (arteriovenous oxygen difference) What is the gold standard to measure Cardiorespiratory fitness? >>>>VO2 max during open circuit spirometry. How does a submaximal exercise test work? >>>>It estimates VO2 max from the HR response to submaximal single stage or graded exercise. absolute oxygen consumption vs. relative oxygen consumption >>>>absolute is the raw volume of O2 consumed by the body. Relative is the volume of O2 consumed relative to body weight. Useful to compare fitness levels between individuals. What is one of the largest components of PA-related energy expenditure? >>>>Occupational Physical Ativity 5 Health related physical fitness components >>>>Cardiorespiratory endurance, body composition, muscular strength, muscular endurance, and flexibility 6 Skill (performance) related physical fitness components >>>>Agility, coordination, balance, power, reaction time, and speed cardiorespiratory endurance >>>>ability of circulatory system and respiratory system to supply o2 during sustained physical activity Body composition >>>>relative amounts of muscle, fat, bone, and other vital parts of the body Muscular strength >>>>Ability of muscle to exert force
