An untrained college-aged athlete begins a resistance training program. After training for 3 weeks, her strength increases dramatically. Which of the following is the most influential factor responsible for this improvement? Oimproved ratio of muscle to fat components Oincreased neural activation Oincreased quantity of muscle fibers O increased cross-sectional area of muscle fibers

An inexperienced (novice) client has completed the first two weeks of a resistance training program designed to increase muscle size and strength. The athlete approaches you and expresses frustration that she does not see any sign of an increase in muscle size or fat-free body mass. Considering the time course of contributions from neural adaptations versus hypertrophy, explain to the athlete why this is normal following just two weeks of resistance training.

What is the primary cause of muscle growth during an appropriately structured resistance training program?
The force generated by a single muscle fiber can be increased by: A) increasing the frequency of action potentials only. B) increasing muscle length beyond optimal only. C) increasing the asynchrony of recruitment only. D) increasing the frequency of action potentials and increasing muscle length beyond optimal only.
