Running the cells through a wide spectrum of stimuli was a way of waking up all the regulators--in a sense, shaking the bushes and then nabbing them once they're out.

"By changing the way skeletal muscles respond to low-oxygen levels, we've developed muscles that appear to be superiorly adapted or trained for long bouts of submaximal aerobic exercise. But these muscles also become damaged more easily than normal muscles during exercise and we don't know why."...Muscles are smarter than you think

'When a muscle is worked hard, potassium ions come out of the fibres and make the membrane less excitable.
