young - Opis:
- Mounting research has linked acute moderate-intensity exercise with changes indiscrimination of similar events – i.e., mnemonic memory. Conversely, few studies have compared performance in tasks associated to each type of memory(mnemonic similarity and emotional) and less have evaluated performance several days after exercise sessions. Thirty-five undergraduate students were randomly distributed in three groups that differed in the assigned duration of the moderate-intensity ex- ercise session. We established first the moderate-intensity exercise program by calculating the VO2max 50%. Two-to-five days later, participants engaged in the exercise condition to which they were assigned, followed by a five-minute rest period. Immediately after, all participants were ex posed to the training phase of both memory tasks. The first retrieval phase was tested 45 minutes after encoding phase was completed. Subsequent retrieval phases were conducted 24, 48, and 168 hours post-training. Exercise of long duration increased discrimination performance in images of low similarity. Comparison of the effects of exercise on discrimination of the three types of images that the emotional-memory task entails showed improved performance only for aversive and neutral images. Exercise improves discrimination of low similarity images, with better overall perform- ance after a longer exercise session. This finding adds to previous reports that have found analogous effects using other memory tasks. It also supports the notion that acute effects due to exercise are specifically related to hippocampal functionality and its ability to separate patterns. Finally, maintenance of emotional informa- tion across time suggest a different mechanism, independent of pattern- separation processing. ----------------------------------------------------------------------------------------------------------------------------
