When a system is exposed to a specific type of exercise on repeated occasions, the system adapts. In the case of muscle with resistance training, there are several adaptations. The end result of these changes is an increased ability to generate force by that muscle. There are a few things to consider, including the cellular changes and neural changes.   Which of the following are likely adaptations by the nervous system to resistance training? (identify all that apply)   a. increased motor unit recruitment (agonist activity) b. asynchronous firing of motor units c. greater area of the neuromuscular junction d. increased activation of the antagonist muscles e. increased activation of the synergist muscles
