A sports scientist wanted to investigate whether a new compression garment improves recovery time after high-intensity interval training (HIIT).
A pool of 40 endurance runners was recruited. The runners were paired up based on their baseline fitness levels and age. One runner from each pair was randomly assigned to wear the compression garment during recovery, while the other runner in the pair wore standard athletic clothing. Recovery time (in hours) was then recorded for all participants.
