CSEP-CPT Exam Preview examinable sections.100% Accurate, rated A+ Cardiac Output - ✔✔-The amount of blood the heart pumps through the circulatory system in a minute. The amount of blood put out by the left ventricle of the heart in one contraction is called the stroke volume. The stroke volume and the heart rate determine this. - typically about 5L/min at rest - will be higher if physically fit (max of 40L/min) - for unfit, 14-20L/min max Stroke Volume - ✔✔-Refers to the volume of blood that is pumped by the heart with each contraction - during PA, it will increase until intensity reaches ~50% of VO2 max, then HR will increase the cardiac output - for physically fit people, SV is likely to be higher and RHR likely to be lower Blood Pressure - ✔✔-Refers to the pressure blood exerts on walls of blood vessels, and reflects efficiency of blood flow through the CV system - systolic: heart contracting - diastolic: heart relaxing 120/80 is normal 144/94 max safe ranges normal BP for healthy, active adult is 110/70 - during PA, systolic will rise slightly and diastolic will remain roughly the same Heart Rate - ✔✔-number of heart beats/minute - RHR average 60-80bpm - higher RHR for women - lower RHR with age Normal Responses to short-term, light-mod Aerobic Exercise - ✔✔-CO: Increases rapidly; plateaus at steady state within 2 min SV: Increases rapidly; plateaus at steady state within 2 min HR: Increases rapidly; plateaus at steady state within 2 min SBP: Increases rapidly; plateaus at steady state within 2 min DBP: shows little or no change Normal Response to Long-Term, Light to Moderate to Heavy Submaximal Exercise - ✔✔-CO: increases rapidly; plateaus SV: increases rapidly; plateaus; negative drift HR: increases rapidly; plateaus; positive drift SBP: increases rapidly; plateaus; slight negative drift DBP: shows little or no change Normal Response to Incremental Aerobic Exercise to Maximum - ✔✔-CO: rectilinear increase with plateau at max SV: increases initially;plateaus at 40-50% vo2 max HR: rectilinear increase with plateau at max SBP: rectilinear increase with plateau at max DBP: shows little or no change Normal Response to Static Exercise - ✔✔-CO: modest gradual increase SV: Relatively constant at low workloads; decreases at high workloads; rebound rise in recovery HR: modest gradual increase SBP: marked steady increase DBP: marked steady increase Normal Response to Resistance Exercise - ✔✔-CO: Modest gradual increase SV: Little change, slight decrease HR: Increases gradually with numbers of reps SBP: Increases gradually with numbers of rep DBP: no change or increase Cardio respiratory Response to Acute Exercise - ✔✔-HR anticipatory response - HR increases at the beginning of exercise increased cardiac output redistribution of blood to working muscles and heart increased blood pressure vasoconstriction to smooth muscles vasodilation to skeletal muscles Cardio Respiratory Response to Chronic Exercise - ✔✔-- decrease in RHR - decrease in SV at rest - improved circulation - BP decrease by up to 10mmHg - increased blood volume Anaerobic (Alactic) Energy System - ✔✔-Fuels: ATP & CP Time Frame: 0-15s By-Products: ADP, Cr + Pi (creatine + inorganic phosphate) Activity Examples: 100m sprint, jumping, agility, weight lifting Anaerobic (Lactic) Energy System - ✔✔-Fuels: CHO 'incomplete breakdown' Time Frame: 15-120s By-Products: lactic acid, 2 ATP/ mol CHO Activity Examples: 200m (power), 800m (endurance), resistance training Aerobic Energy System - ✔✔-Fuels: CHO, fats, protein (<5%) "complete breakdown" Time Frame: 120s - several hours By-Products: CO2, water, heat, 36 ATP/mol CHO (net) Activity Examples: distance running, 1500m (power), marathon (endurance or capacity) Most Valid and Direct measure of VO2 Max - ✔✔-For aerobic fitness the gold standard test is considered to be a direct measurement of a client's maximal oxygen consumption (VO2 max). This test is performed in a lab where the actual amount of oxygen and carbon dioxide breathed in and out during maximal exercise can be measured as it is breathed into a bag or tank. As this test directly measures the maximal amount of oxygen used this is considered a very valid test to measure aerobic capacity. Absolute VO2 Max - ✔✔-does not consider a person's weight Relative VO2 Max - ✔✔-considers a person's weight Muscular Strength - ✔✔-refers to the amount of force a muscle can produce with a single maximal effort. Muscular Endurance - ✔✔-the ability of a muscle or group of muscles to repeatedly exert force against resistance Muscular Power - ✔✔-the ability to exert a maximal force in as short a time as possible, as in accelerating, jumping and throwing implement Muscular Flexibility - ✔✔-refers to the absolute range of movement in a joint or series of joints, and length in muscles that cross the joints to induce a bending movement or motion. Third Class Lever - ✔✔-The force is applied between the fulcrum and the load. Therefore the load lever arm is always greater than the force lever arm. A classic example is a pair of tweezers or a diving board. Mechanical Advantage = Less than 1 Most muscles in the human body are 3rd class levers and create rotation of the distal segment. With this type of leverage the muscles would be acting concentrically, as long as the distal lever is free. An example of this type of lever system is the biceps brachii acting concentrically on the forearm. Sedentary Behaviour - ✔✔-refers to any waking activity characterized by an energy expenditure of [Show More]
