Introduction:
Anxiety and depression are psychiatric disorders that have a deleterious effect on human mental health. Meanwhile, various forms of exercise have been demonstrated to have beneficial effects on the reduction of symptoms of anxiety and depression. However, the disparate effects of each exercise on mood symptoms remain to be elucidated. This research examines the different effects of each type of exercise on mood symptoms and electroencephalography (EEG) activity.
Methods:
Accordingly, subjects engaged in six weeks of aerobic and resistance exercises with a 3-week washout period between each intervention. The Score of Hospital Anxiety and Depression Scale (HADS) was employed to assess the severity of both anxiety and depression. For the purposes of EEG analysis, we calculated the values of theta/beta ratio (TBR), Higuchi Fractal Dimension (HFD), and frontal alpha asymmetry (FAA).
Results:
Both types of exercise resulted in the alleviation of both anxiety and depression. Notably, aerobic exercise significantly decreased the score of HADS-A (anxiety), while resistance exercise significantly improved HADS-D (depression). In the context of EEG analysis, a significant decrease of TBR in the left frontal region was observed after aerobic exercise.
Discussion:
Therefore, these findings emphasize the importance of personalized exercise strategies for those suffering from anxiety and depression. Furthermore, further investigation into the impact of exercise on brain wave activities associated with anxiety and depression are needed.

Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...

The Role of Exercise in Stress Management
Regular physical activity is essential for reducing stress and promoting cardiovascular health. Exercise strengthens the heart, enhances blood flow, keeps blood vessels flexible, and helps lower blood pressure, all of which reduce the body's stress response. Research shows that adults who exercise regularly have nearly half the...
