The Claim
Supervised Nordic walking performed twice weekly at moderate intensity (65-75% HRmax) for 10 weeks is associated with a large reduction in depressive symptoms, with a mean decrease of 13.6 points on the Beck Depression Inventory-II, most pronounced in the first five weeks (Hedges's g = -0.98), particularly among individuals with severe baseline depression.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
People who participated in supervised Nordic walking twice a week at moderate intensity for 10 weeks showed a mean reduction of 13.6 points on the Beck Depression Inventory-II, with the greatest improvement occurring in the first five weeks and larger effects in those with severe depression at baseline.

Physical activity reduces inflammatory signals in the blood, which allows the brain to restore normal levels of mood-regulating chemicals and repair stress-damaged circuits, leading to improved emotional control.
What the research says
1 studyPeople with moderate to severe depression who did supervised Nordic walking twice a week for 10 weeks felt much better, especially in the first five weeks — and those who were most depressed at the start improved the most.
