Abstract/OtherAbstract:
Recovery of the rate of dynamic muscular endurance was measured in two groups of college-aged males. Subjects were required to perform elbow flexion (between the angles of 70 and 170 degrees) for as long as possible at the rate of 38 contractions/min while loaded with 1/6 of their maximum isometric strength (MVC). The task was terminated when the subject fell four contractions behind the required cadence or failed to complete two successive contractions. Subsequent to the task the subject was given a predetermined rest period after which a second fatigue bout to failure was performed. The rest intervals for Gp I (n = 22) were 5, 15, 45, 135, 405, and 1215 seconds, while the rest intervals for Gp II (n = 17) were 10, 30, 90, 270, 810, and 2550 s. Each subject completed six recovery intervals with the order of administration assigned at random. The percentage of recovery was calculated by dividing the exercise time of the first bout into the time of the second bout. These normalized data for the two groups were combined for analysis providing a 12 point recovery curve. The percentage of recovery ranged from 15.4% after 5 s to 91.8% after 2550 s. Analysis of the data revealed that the recovery pattern of dynamic muscular endurance progressed very rapidly initially, reached 50% at approximately 2 min and 15 s and was slightly less than 90% complete at 20 min. Exponential analysis of these data yielded a three-component curve.
