Two-week high-frequency aerobic exercise reduces depressive symptoms and improves frontal function in subthreshold depression

A two-week high-frequency aerobic exercise (6-7 sessions/week) significantly decreased BDI-II and PHQ-9 scores in female participants with subthreshold depression, while increasing response and remission rates. The intervention also reduced activation in the dorsolateral prefrontal cortex, frontal eye field, and premotor and supplementary motor areas, and improved functional connectivity and network efficiency.

Mechanism Graph

Aerobic exercise reduces activation in dorsolateral prefrontal cortex, frontal eye field, and premotor/supplementary motor areas
↓
Decreases functional connectivity strength between DLPFC and FEF, PMC-and-SMA, and S1
↓
Improves network efficiency within S1 and FEF (enhanced node efficiency, increased degree centrality, reduced shortest path)
↓
Functional enhancement of PMC-and-SMA and FEF is associated with alleviation of somatic symptoms (sleep disturbances and fatigue)

Limitations

  • ⚠Only female participants were included, limiting generalizability to males
  • ⚠Short follow-up period (two weeks) does not assess long-term sustainability of benefits

Frequently Asked Questions

How often did participants exercise in this study?▼

Participants exercised 6-7 times per week for two weeks.

What were the main outcomes measured?▼

Depressive symptoms were measured using BDI-II and PHQ-9, and brain activity was assessed using functional near-infrared spectroscopy during a verbal fluency task.

Did the exercise improve sleep and fatigue?▼

Yes, improvements in somatic symptoms including sleep disturbances and fatigue were associated with functional brain changes in the premotor and supplementary motor areas and frontal eye field.

Is this study applicable to men?▼

No, the study only included female participants, so results may not generalize to men.
