Animals in this study were subjected to three levels of fatigue: chronic fatigue, fatigued once and no fatigue. The chronic fatigue group was forced to swim to exhaustion on 14 consecutive days while those animals in the fatigued group were exhausted only one time. The third group served as a control and did not swim to exhaustion. Each of these groups contained equal numbers trained mice were subjected to the exhaustive swims. Another of both sedentary and trained mice. The a five week program of swimming prior to variable was the time animals exercised, with half swimming in the morning of day in which the and the rest swimming in the evening. At the end of the last exhaustive swim, one animal from each of the twelve experimental groups was sacrificed. Micrographs of the muscle tissue were made and the number of muscle bundles per micrograph of equal magnification were compared. There difference at the ultrastructural level between trained mice. No significant difference at the ultrastructural was no significant and sedentary level between mice trained in the morning and evening was found. Finally, no significant difference between the three levels of fatigue was found at the ultrastructural level.
