Abstract

Studies have shown that chronic physical activity can alter anxiety in a variety of contexts. Adolescent (postnatal day 30) or
early adult mice (postnatal day 60) were exposed of 8 weeks of swimming exercise. The swimming exercise significantly increased
open arm exploration in plus maze in plus-maze test (F36, 3 = 7.565; p<0,001). Moreover, swimming training increase
time of ambulação (F36,3 = 33.739; p<0,001) and decreases total time spent immobilized (F36,3 = 13.039; p<0,001) in the open
field, having thus an anxiolytic effect. The open field showed that among sedentary young mice were less anxious than adults
and the young swimmers showed higher exploratory activity (F36,3 = 2.953; p<0,05) and grooming (F36,3 = 2.672; p<0,05).
Taken together, we conclude that swimming exercise appears to result in decreased anxiety.
