ACE PERSONAL TRAINER CHAPTER 8
EXAM 2025 QUESTIONS AND ANSWERS
Definition of strength training - ANS Exercising with progressively heavier resistance for the
purpose of strengthening the musculoskeletal system
Positive adaptations of strength training - ANS Increased muscle fiber size, contractile
strength, tendon tensile strength, bone strength, ligament tensile strength
Physical capacity - ANS One's ability to perform work or exercise
Two month gains for untrained men and women - ANS 4 pounds of muscle and 40-60% more
strength
How much muscle lost every year after 25? - ANS one and a half pounds unless you do
regular strength exercises
Skeletal muscle calorie use % - ANS 25% when we sleep
Increases in muscle tissue causes... - ANS increase in metabolic rate
Gradual loss of muscle tissue in adults leads to... - ANS 5% reduction in metabolic rate every
decade
Other roles of the muscles - ANS balancing agents and shock absorbers

, Jogging stress on legs and what can happen - ANS posterior leg muscles than anterior leg
muscles. So there is a muscle imbalance that can lead to knee injuries
Americans with low back pain - ANS 4 out of 5
Percentage of low back pain injuries that are muscular and are preventable - ANS 80%
Isometric contraction - ANS Muscular force is equal to the resistive force
Concentric contraction - ANS Muscular force greater than resistive force
Eccentric contraction - ANS Muscular force less than resistive force
Eccentric contraction is also known as a... - ANS negative contraction
concentric contraction also known as a... - ANS positive contraction
Internal muscle friction during concentric contraction - ANS subtracts about 20% from
possible output
Internal muscle friction during eccentric contraction - ANS adds about 20% from possible
output
Prime mover muscles - ANS Muscles that are principally responsible for a given joint
movement
Antagonist muscles - ANS Muscles that produce the opposite joint movement
