ACSM Certified Exercise Physiologist Exam with Guaranteed Accurate Answers

Physical Activity - correct answer Any bodily movement produced by contracting skeletal muscles, with an increase in energy expenditure. Exercise - correct answer Planned, purposeful, repetitive Physical Fitness - correct 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 - correct answer 1. Creatine Phosphate 2. anaerobic glycolysis 3. 0xidative system Claudication - correct answer pain in the leg is induced by exercise, usually because of an artery obstruction. Creatine Phosphate system - correct 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 - correct 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) - correct 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? - correct answer The volume of oxygen the body consumes. VO2 max is the highest volume of oxygen the body can consume. Define Stroke Volume - correct answer the volume of blood the heart ejects with each beat. How does SV increase with workload? - correct 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? - correct answer it decreases, as more blood being pumped per beat allows the heart to beat less often. What is cardiac output? - correct answer a measure of blood pumped per minute. The product of stroke volume and heart rate. What does Diastolic Blood pressure do during exercise? - correct answer Remains stable or decreases slightly. What is rate pressure product? - correct answer serves as an estimate of myocardial oxygen demand. Produ
