Perceived exertion of professional hockey players

18 professional hockey players were tested on the treadmill with a modified Balke procedure and also for maximum isokinetic strength with the Cybex II instrument. Immediately after each test the subject completed the Borg Scale of Perceived Exertion. The treadmill effort was perceived as being "somewhat hard work" while the maximum strength effort was considered "very light." This conflicts with previous literature. It may be that professional hockey players adapt to physical stress and do not respond perceptually to such stimuli in a typical manner.
