Abstract
The aim of this study was to examine the positive effects of forced and
voluntary exercises as a non-pharmacological factor on modified behaviors
due to stress of separation from mother. In the present study, 48 male baby
rats were selected and separated from their mothers from day 2 to 14 for 180
minutes. On the 21st day, these rats were randomly divided into 4 groups.
The groups included maternal stress, control, treadmill, running wheel (RW).
The first group experienced stress of separation from their mothers from day
2 to 14 and the control group was kept from the beginning with their
mothers. The exercise groups also began to exercise since their 21st birth
day. Then, the groups conducted behavioral anxiety and rodent depression
tests including EPM, Splash, FST, and Open Field. The obtained data were
statistically analyzed by t and ANOVA methods at a significance level
(P<0.05). Behavioral tests showed that the stress of separation from the
mother caused depression behaviors. On the other hand, voluntary exercise
caused antidepressant effects compared with the stress group while no
significant changes were observed between the effect of forced exercise and
the stress group. The results showed that exercise, especially voluntary
exercise, reduces stress during adolescence, and reduces depression and
anxiety behaviors in adulthood.
