Strength Recovery Following Rhythmic or Sustained Exercise as a Function of Time.
Kearney, Jay T.
The relative rates of strength recovery subsequent to bouts of rhythmic or sustained isometric exercise were investigated. The 72 undergraduates who served as subjects were tested seven times within the framework of a repeated measures design. Each testing session involved two bouts of either rhythmic or sustained isometric exercise separated by a rest interval of 5, 10, 20, 40, 80, 160, or 320 seconds. Strength recovery was evaluated by comparing the level of strength expressed at the conclusion of the initial fatigue bouts, final strength, and the initial strength measure of the second exercise bouts. Analysis of variance and related statistics indicated that a) significant strength decrements of similar magnitude were produced by both types of activity; b) the group of subjects who initially performed rhythmic exercise consistently stronger than those performing sustained exercise; c) strength at the end of the first exercise bout was significantly lower than final recovery strength; and d) initial strength and final recovery strength failed to differ significantly. Although not in complete accord with previously published results, these results show that the patterns of strength recovery subsequent to rhythmic and sustained isometric exercise were similar.
