The acute effects of different cadences on performance during maximal effort push-up and pull-up exercise were evaluated. Subjects, 75 college age males, completed a within-subjects balanced design involving three cadences (fast self-paced, 2/2, and 2/4). For each condition they completed as many repetitions as possible. The number of repetitions, work, and power output differed for each cadence and exercise mode, and interactions occurred between modes for repetitions, work, and power output. During self-paced pull-ups, subjects completed 96% more repetitions and work, in 16% less time, and attained 131% greater power output than during 2/4 exercise. Likewise, during self-paced push-ups they performed 145% more repetitions and work, in 51% less time, and attained 399% greater power output than during 2/4 exercise. Repetitions, work, and power output scores for the 2/2 cadence were midway between those for the self-paced and 2/4 cadences for each mode. The findings indicate that the amount and rate of work performed during a single bout of exercise depends on the exercise cadence. Verf.-Referat
