ACSM Certified Exercise Physiologist Exam Questions With Verified Solutions | Latest Updates Physical Activity - ANSWER Any bodily movement produced by contracting skeletal muscles, with an increase in energy expenditure. Exercise - ANSWER Planned, purposeful, repetitive Physical Fitness - ANSWER 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 - ANSWER 1. Creatine Phosphate 2. anaerobic glycolysis 3. 0xidative system Claudication - ANSWER pain in the leg is induced by exercise, usually because of an artery obstruction. Creatine Phosphate system - ANSWER 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 - ANSWER 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) - ANSWER 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? - ANSWER The volume of oxygen the body consumes. VO2 max is the highest volume of oxygen the body can consume. Define Stroke Volume - ANSWER the volume of blood the heart ejects with each beat. How does SV increase with workload? - ANSWER 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? - ANSWER it decreases, as more blood being pumped per beat allows the heart to beat less often. What is cardiac output? - ANSWER a measure of blood pumped per minute. The product of stroke volume and heart rate. What does Diastolic Blood pressure do during exercise? - ANSWER Remains stable or decreases slightly. What is rate pressure product? - ANSWER 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? - ANSWER VO2max = HRmax X SVmax X a-VO2 difference max (arteriovenous oxygen difference) What is the gold standard to measure Cardiorespiratory fitness? - ANSWER VO2 max during open circuit spirometry. How does a submaximal exercise test work? - ANSWER It estimates VO2 max from the HR response to submaximal single stage or graded exercise. absolute oxygen consumption vs. relative oxygen consumption - ANSWER 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 individu
