PAHL Exam 2 -Peterson questions &
answers graded A+ passed
Identify two physiological adaptations associated with chronic endurance training - correct
answer ✔✔↑ Aerobic power (VO2max)↑ Capillary density↑ Mitochondrial density↑ Increases
maximal cardiac output / stroke volume↑ Arteriovenous oxygen difference↑ Improves
connective tissue strength↑ Metabolic enzyme number / activity↑ Metabolic energy stores
(e.g., ATP, CP, glycogen, triglycerides)↓ Percent body fat↓ Resting and maximal heart rate↓
Resting cardiac output / stroke volume↓ Resting and maximal blood pressure
What are the three basic energy systems used to replenish levels of ATP? - correct answer
✔✔Phosphagen, Glycolytic, Oxidative
Match each energy system with the most suitable type of exercise to train the system - correct
answer ✔✔Phosphagen (100m sprints), Glycolytic (400m sprints), Oxidative (1 mile run)
Which energy system(s) is/are anaerobic (not requiring the presence of oxygen) - correct
answer ✔✔Phosphagen and Glycolytic
Which energy system produces the most ATP - correct answer ✔✔Oxidative
Which type of muscle fibers performs better at long endurance events? - correct answer
✔✔Slow twitch
High level short distance sprinters will tend to have a higher percentage of which type of muscle
fibers? - correct answer ✔✔Fast twitch
, Identify two physiological adaptations associated with chronic strength training. - correct
answer ✔✔↑ Rate of force production↑ Fiber cross-sectional area↑ Myofibrillar volume↑
Myosin heavy chain protein↑ Metabolic enzyme activity↑ Metabolic energy stores (e.g., ATP,
CP, glycogen)↑ Strength of connective tissue (tendons, ligaments)↓ Percent body fatSlows
down the aging process
During a triceps extension exercise, identify which muscles act as the agonist, antagonist, and
stabilizers: - correct answer ✔✔Shoulder and back muscles= stabilizers
Biceps brachii muscle= Antagonist
Triceps brachii muscle= Agonist
Which type of contraction occurs when a muscle is shortening? - correct answer ✔✔Concentric
Which type of contraction occurs when a muscle is not moving/maintaining a holding position
(no change in length)? - correct answer ✔✔Isometric
5 compound lifts - correct answer ✔✔bench, row, press, squat, deadlift
What are the benefits of incorporating compound lifts in a strength training program? - correct
answer ✔✔Produce greater increases in muscle size and strength than assistance exercises
Direct application to sportand functional activities
Which principle related to strength training states that the training stimulus must increase over
time in order to see progress? - correct answer ✔✔Progress overload (All options: Specificity,
Reversibility, Progressive overload, Accommodation, and Individuality)
Between the ages of 30 and 65 the average American loses ___ pound(s) of muscle and gains __
pound(s) of fat each year.1 - correct answer ✔✔0.5 and 1
