Upon arriving at the laboratory, the load was set for each
subject according to the previously established 1RM. For the
90FAIL and 30FAIL leg, participants performed the exercise and
were given verbal encouragement until concentric failure. Failure
was recognized when a complete range of motion for the exercise
could not be completed. During the 30WM trial subjects
performed the same amount of external work as in the 90FAIL
trial and therefore exercise was not performed to failure. For all
training loads, subjects performed four sets and were given three
minutes rest between sets. The subjects were instructed on proper
lifting cadence based on verbal cues and a metronome set to 50
beats per min, which corresponded to 1-s concentric muscle
action, 0-s pause, and a 1-s eccentric muscle action. Time-undertension
was recording with a standard chronometer.
