Key result
Moderate-intensity physical exercise significantly improved the EEG asymmetry index in response to negative emotional stimulations compared to pre-exercise levels (p=0.0254).

Does short-term moderate-intensity physical exercise improve emotional response to negative stimulations in healthy young adults?
p-value: p=0.0254
Short-term moderate-intensity physical exercise significantly improves the emotional response to negative stimulations, as evidenced by positive shifts in frontal EEG asymmetry.
Suggests acute emotional benefits from moderate exercise in healthy adults; extends RCT evidence on EEG markers but leaves clinical translation open.
It is widely accepted that physical exercises (PEs) not only are good for fitness but also contribute to mental health and well-being. The positive influence of PEs on emotion has become a topic of much excitement. However, a quantitative study is required to discuss the effect of short-term moderate-intensity PE on the emotional response by using electroencephalogram (EEG) asymmetry. The experiments, including 20-min moderate-intensity cycling and EEG data acquisition with picture-induced emotion assessment protocol, were designed in this paper. The experiment procedure consists of two emotion assessment sessions, each of which contains 24 pictures. About 80 participants were randomly allocated into the exercise group and the control group. Participants in the exercise group were instructed to have a 20-min moderate-intensity cycling after the first assessment session, then rested until their heart rates recovered to baselines and their emotional states were assessed again in the second session. The control group only had a 20-min break without the cycling exercise between the two sessions. It was observed that, in the control group, the EEG asymmetry had no significant difference in these two assessment sessions for both positive and negative stimulations. However, in the exercise group, the difference of the EEG asymmetry before and after PE was significant only in response to negative stimulations. Further, the in-depth analysis of EEG asymmetry index changes of individual participants shows that the short-term moderate-intensity PE has a positive impact in response to negative stimulations. The proposed experiments show that the negative emotional experience can be reduced by the moderate-intensity PE and support the hypothesis that the moderate-intensity PE is good at improving emotional response to negative stimulations. This study provides the evidence of positive effects of PE in the domain of emotion regulation with experimental data.

Long et al. (2021) conducted an RCT in Healthy (n=80). Moderate-intensity physical exercise (cycling) vs. 20-minute rest was evaluated on Difference in EEG asymmetry index (Asy) in response to negative stimulations (p=0.0254). Moderate-intensity physical exercise significantly improved the EEG asymmetry index in response to negative emotional stimulations compared to pre-exercise levels (p=0.0254).
