Background: Over the years the resistance exercise (RE) becomes notorious because of its effects on the psychobiological aspects. However, doubts still remain particularly related
acute responses. The objective was to investigate the effects of different sessions of RE in mood and cognition.
Methods: Participated thirteen young average age and BMI respectively 29.92 ± 3.07 years and 24.88 ± 2.63kg /m2, which were submitted to an acute session of dynamic force (DF) and
muscle resistance (MR) lasting 50 minutes, with an interval of seven days between sessions. Before, immediately after (IA), 30 and 60 minutes after the end of the sessions, the volunteers were
evaluated for mood profile by Brunel Mood Scale – BRUMS, Visual Analogue Scale of Humor – VAMS, Experience Subjective Scale Exercise - SEES, STAI trait and state and cognition by Digit Span -
concentrated attention and mental control Test; Game Dice Task - decision making under risk test; Vienna Test System - reaction time test, simple and multiples choices test; N-Back -work memory. Was
used the two-way ANOVA with post hoc Duncan, adopting p <0.05. The protocol was approved by Unifesp Ethics Committed (#1634/08).
Results: The results revealed that the DF condition showed decrease in the mean motor (p <0.01) IA observed in reaction time test. The tension-anxiety analyzed by BRUMS decreased 30
(p = 0.03) and 60 (p = 0.03) minutes after exercise when compared to baseline. It showed in DF condition an increased in mental sedation (p = 0.03), and decrease in anxiety (p = 0.02) IA when compared
to baseline by VAMS test. In the MR condition, positive well-being (p = 0.03) decreased IA and psychological distress scale (p = 0.02) increased IA when compared to the baseline by SEES test.
Conclusions: Our data suggest that the exercise of DF promotes a beneficial effect on aspects of mood and cognition when compared to MR exercise.
