. Threshold contrast sensitivity was measured using sinusoidal gratings with the method of increasing contrast both before and after jogging in fresh air. The mean contrast sensitivity of 11 subjects was higher after jogging at all three spatial frequencies studied (1, 6 and 19 c/deg). The differences were statistically significant. The effect of jogging was subject to individual variation, some ‘unstable’ subjects responding strongly and some ‘stable’ subjects showing no change at all. Two ‘unstable’ subjects were tested several times, and their strong response proved to be repeatable.
