For a Powerlifter, work
capacity is highly specific - there are three major lifts that a Powerlifter will need to perform three times each during a meet (with a total competition period of exertion in the region of 20 - 30 seconds
over a 3 - 4 hour meet), so one could think that work
capacity is almost irrelevant - yet to maximize training benefit the ability to
repeatedly handle near maximal weights with good form and recover adequately between work sets may be highly desirable.
