Abstract
The purpose of the study was to compare the effects of rest, exercise, and cold applications upon physical performance. Eighteen college men students served as subjects. They performed five bouts of spot-running, with ten-second intervals between the bouts. After they rested, exercised, or received cold applications for ten minutes, they performed another series of five bouts of spot-running. The best performance followed the application of the cold spray to the lower half of the abdomen.
