Passage A.

Puzzling phenomenon · Gaining muscle after inactivity is easier if you've already trained those muscles before

One hypothesis · Body uses more muscle fibers as you train more

When you return to training after inactivity, your body might be able to start off using more muscle fibers that were previously activated by past training.

Another hypothesis · Psychological explanation

If you've trained before, you know how much you can lift. So you increase weight more quickly when starting to train again.

███████ █

Phenomenon and hypothesis · Building muscle is easier for people who used to be strong because of something retained by muscles

Details of hypothesis · Muscle cells merge with stem cells during training

The muscle cells incorporate the stem cells' nuclei.

Details of hypothesis · Muscles retain the stem cells' nuclei even after inactivity

These nuclei can make more muscle proteins again, even after the muscles have shrunk due to inactivity.

Passage B doesn’t give any reason to doubt bodybuilders’ experience of muscle memory or any other experience.

It reflects a █████████ ███████ █████████ ██████████ ███ █████████ █████████ ██ ███ ████████ █████ ██ █████ ████████

Passage B doesn’t give any reason to think that the allegedly puzzling nature of muscle memory has anything to do with some divide between experience and cellular processes. Passage B brings up research that suggests a cellular explanation for the athlete’s experience of muscle memory.

Passage B doesn’t suggest that most athletes wouldn’t find muscle memory to be puzzling.

It is less ███ ███ ██ █████ ██ ██████ ████████ ████ ██ ███ ██████ ████ ████████ ███ ██████████

Supported, because Passage B describes recent research that provides evidence of the cause of muscle memory. So Passage B would likely agree that muscle memory is less puzzling after the research.

Passage B doesn’t suggest that those who find muscle memory puzzling have a misunderstanding of exercise psychology. Passage B doesn’t even mention exercise psychology or the principles of it.
