Brief summary
This exploratory randomized controlled trial aims to investigate the immediate and long-term effects of exercise on sleep quality, emotional problems, executive function, and neurophysiological characteristics in college students with depressive symptoms. The study consists of two sequential phases: an acute exercise experiment followed by an 8-week exercise intervention. Participants will be randomly assigned to either an exercise intervention group or a control group. Psychological questionnaires, behavioral tasks, resting-state electroencephalography (EEG), brain functional connectivity, and event-related potentials (ERP) will be assessed to evaluate behavioral and neurophysiological changes before and after exercise. The study will further examine whether the immediate response to acute exercise predicts the effectiveness of the long-term intervention.
Detailed description
Depressive symptoms are highly prevalent among college students and are frequently accompanied by poor sleep quality, emotional disturbances, impaired executive function, and altered brain activity. Although physical exercise has been recognized as an effective non-pharmacological intervention for improving mental health, the neurophysiological mechanisms underlying these benefits remain unclear. This study adopts an exploratory randomized controlled design consisting of two consecutive phases. In Phase I, participants will complete a single session of low-to-moderate intensity exercise to investigate immediate changes in emotional state, executive function, resting-state EEG, brain functional connectivity, and event-related potentials (ERP). In Phase II, the same participants will continue to participate in an 8-week exercise intervention to examine the effects of regular exercise on sleep quality, depressive symptoms, emotional problems, executive function, and neurophysiological characteristics. Behavioral assessments, standardized psychological questionnaires, resting-state EEG, brain functional connectivity analysis, and ERP recordings will be performed before and after intervention. The study will also investigate whether the immediate response to acute exercise is associated with subsequent improvements following long-term exercise intervention, providing evidence for individualized exercise prescriptions and neurophysiological mechanisms of exercise in college students with depressive symptoms.
Interventions
BEHAVIORALArchery Exercise
Participants perform a standardized archery exercise program consisting of an acute exercise session followed by an 8-week supervised training program. The acute session includes a 5-minute warm-up, 20 minutes of archery exercise, and a 5-minute cool-down. The long-term intervention is conducted three times per week for 8 weeks at moderate exercise intensity.
BEHAVIORALNon-exercise Control
Participants continue their usual daily activities without participating in the archery exercise intervention.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Depressive symptoms measured by the Beck Depression Inventory-II (BDI-II) | Baseline, immediately after the acute exercise session, and after completion of the 8-week intervention. | Depressive symptoms will be assessed using the Beck Depression Inventory-II (BDI-II). Changes in depressive symptom severity following acute and long-term archery exercise interventions will be evaluated. |
| Sleep quality measured by the Pittsburgh Sleep Quality Index (PSQI) | Baseline, immediately after the acute exercise session, and after completion of the 8-week intervention. | Sleep quality will be assessed using the Pittsburgh Sleep Quality Index (PSQI). Changes in sleep quality after acute and long-term archery exercise interventions will be evaluated. |
| Resting-state EEG functional connectivity | Baseline, immediately after the acute exercise session, and after completion of the 8-week intervention. | Resting-state EEG functional connectivity will be analyzed using phase synchronization metrics to evaluate neural changes associated with archery exercise interventions. |
