ACSM Certified Exercise Physiologist (All Correctly Answered)

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