Computerized electrophysiological evaluation of muscular fatigue.
Muscular fatigue was studied in relation to different types of exercises. Thirty rats were divided in three groups: control, aerobic (running) and anaerobic exercises (weight lifting). Computerized measures of fatigue were done, using a special software that has the ability to generate impulses in different intensities. A fatigue index was obtained in a way that the greater the fatigue, the smaller was this index. Relationship among the three groups was possible and we are able to observe that the weight lift group (anaerobic exercises) performed better when compared with the two other groups.
