AFAA PRIMARY GROUP EXERCISE
CERTIFICATION EXAM 2025
List 8 health benefits associated with regular participation in physical activity. - Precise Answer
✔✔Lower risk of coronary heart disease, lower risk of high blood pressure, lower risk of Type 2
diabetes, lower risk of breast cancer, reduced depression, improved cardiorespiraratory & muscular
fitness, lower risk of colon cancer, prevention of weight gain.
How can interval training improve aerobic performance? - Precise Answer ✔✔Maximizes aerobic power
and minimizes boredom.
List 3 physiological adaptations that occur to improve exercise performance and state how or why
improvements occurs. - Precise Answer ✔✔1. Increased maximal blood flow - Performing aerobic
exercise forces large volumes of blood which increases stroke volume.
2. Increased oxygen delivery and carbon dioxide removal - The cardiorespiratory system saturates blood
coming from the lungs with oxygen efficiently. The high pulmonary ventilation assists with the removal
of carbon dioxide during exercise.
3. Increased maximal oxygen uptake and aerobic power - Regular aerobic exercise causes an increase in
the number of capillaries per muscle fiber.
Energy Metabolism
Define energy and its food source. - Precise Answer ✔✔Energy is the ability to do work and the source
of energy is the sun.
Define ATP - Precise Answer ✔✔Adenosine Triphosphate ATP.
Compound that releases energy necessary. for muscular contraction.
1 mole ATP = 1/10 mile energy walk.
Energy Pathways - Precise Answer ✔✔Anaerobic and Aerobic.
,An anaerobic pathway consists of: - Precise Answer ✔✔ATP-CP - phosphagen system.
Fuel source = CHEMICAL creatine phosphate.
Intensity = very high.
Duration = very short 1 to15 seconds.
Activities = sprinting, jumping, throwing, kicking, lifting heavy weights.
An anaerobic pathway also consist of - Precise Answer ✔✔LACTIC ACID SYSTEM
Fuel source = GLUCOSE carbohydrate only.
Intensity = high, moderate.
Duration = short, medium 45-90 seconds.
Activities = prolonged sprints, soccer, basketball, hockey, swimming, cycling.
aerobic pathway consists of: - Precise Answer ✔✔AEROBIC SYSTEM
Fuel source = Carbohydrates, fat, protein.
Intensity = moderate, low.
Duration = medium, very long 3-5 minutes
,Activities = sitting, reading, studying, watching TV, internet surfing, sleeping, walking, biking, rowing,
skating, distance running, aerobics.
Define: Aerobic - Precise Answer ✔✔Aerobic is with oxygen or the presence of oxygen.
Define: Anaerobic - Precise Answer ✔✔Anaerobic is without oxygen; usually w/short-spurt, high-energy
activities
What is the term for Steady state: - Precise Answer ✔✔After first 3-4 minutes of exercise, oxygen
uptake has reached an adequate level to meet oxygen demand of the tissues; heart rate, cardio output,
and pulmonary ventilation have attained fairly constant levels.
What is the term for Excess post-oxygen consumption EPOC - Precise Answer ✔✔Oxygen debt referring
to oxygen uptake remaining elevated above resting levels for several minutes during recovery.
What is the term for Oxygen deficit - Precise Answer ✔✔Period in which the level of oxygen
consumption is below what is necessary to supply ATP production.
What is the term for Anaerobic threshold - Precise Answer ✔✔Point at which the body can no longer
meet its demand for oxygen and anaerobic metabolism is accelerated.
What is the term for Aerobic capacity - Precise Answer ✔✔Ability of the body to remove oxygen from
the air and transfer it through the lungs and blood to the working muscles; related to cardiorespiratory
endurance.
What is the term for Lactic acid - Precise Answer ✔✔By-product of anaerobic metabolism of glucose;
milk sugar.
Aerobic vs. Anaerobic - Precise Answer ✔✔Aerobic - Complete breakdown of glucose.
Anaerobic - Partial breakdown of glucose.
Aerobic - Can utilize carbs, fats, or proteins as fuel.
, Anaerobic - Can only use carbs as fuel.
Aerobic - Long-duration of activity.
Anaerobic - Short-duration of activity.
Aerobic - Smaller EPOC.
Anaerobic - Greater EPOC.
Aerobic - Sub maximal, work moderate intensity.
Anaerobic - Maximal work,,high intensity.
Aerobic - Carbon dioxide and water are end products.
Anaerobic - Lactic acid is the by-product.
Aerobic - Uses oxygen in chemical breakdown.
Anaerobic - Doesn't need Oxigen in chemical breakdown.
What is the term for Stroke volume - Precise Answer ✔✔Volume of blood ejected by each ventricle of
the heart during a single systole.
What is the term for Cardiac output - Precise Answer ✔✔Volume of blood pumped by each ventricle in
one minute.
What is the term for Venous return - Precise Answer ✔✔Pumping action of the muscles in extremities
and respiratory system along with venoconstriction to move oxygen blood back to the heart.
What is the term for Blood pooling - Precise Answer ✔✔Condition caused by ceasing vigorous exercise
too abruptly so that blood remains in the extremities and may not be delivered quickly enough to the
heart and brain.
