EXSC 505 MODULE 5 TESTING, FLEXIBILITY,
AND EXERCISE TECHNIQUE STUDY GUIDE 2026
◉ What is hypertrophy in muscles? Answer: Hypertrophy is the
increase in muscle fiber size due to increased myofibrils and
increased protein synthesis.
◉ What adaptations occur in the neural system with resistance
training? Answer: Increased motor unit recruitment, better
synchronization, improved firing rate, and reduced antagonist
activation.
◉ Why does strength improve before muscle size increases?
Answer: Due to neural adaptations such as increased motor unit
recruitment and synchronization.
◉ What connective tissue adaptations occur with resistance
training? Answer: Increased tendon stiffness, increased ligament
strength, and improved joint stability.
◉ What is the primary adaptation of muscle fibers in strength
training? Answer: Muscle fibers hypertrophy, greatest in type IIX
fibers.
, ◉ What is hyperplasia in muscle fibers? Answer: Possible
hyperplasia refers to an increase in the number of muscle fibers.
◉ What happens to capillary bed density with endurance training?
Answer: There is an increase in capillary bed density.
◉ How does the mitochondrial density change with endurance
training? Answer: Mitochondrial density and volume increase.
◉ What is the difference in muscle fiber adaptations between
anaerobic and aerobic training? Answer: Anaerobic training focuses
on strength and power, while aerobic training focuses on endurance
and fat metabolism.
◉ What is the overload principle in resistance training? Answer: The
overload principle states that muscles must be challenged beyond
normal levels to adapt.
◉ What does the specificity principle in training imply? Answer:
Training adaptations are specific to the activity performed.
◉ What is muscular strength? Answer: Muscular strength is the
extent to which the contractile elements of muscle produce force.
