“IE participants subsequently moved to a separate quiet environment for a three-hr delay period, where they watched nature documentaries, before returning to the exercise lab for a control session. This control session did not involve exercise but used the same context otherwise.”
“For the delayed exercise (DE) group, the protocol was identical but with the order of the exercise and control session reversed; for the no exercise (NE) group, both sessions before and after the delay period were control sessions.”
