The Claim

Whole-body vibration strength-training alters the cortisol awakening response in medication-naïve adolescents with major depressive disorder compared to a non-exertional placebo intervention, with evidence suggesting normalization of hypothalamic-pituitary-adrenal axis dysregulation.

How it works
1 study reviewed
In plain English

In medication-naïve adolescents with major depressive disorder, whole-body vibration strength-training changes the cortisol awakening response and is associated with a shift toward normal regulation of the hypothalamic-pituitary-adrenal axis compared to a non-exertional placebo.

See the scientific wording

Whole-body vibration strength-training may alter the cortisol awakening response in medication-naïve adolescents with major depressive disorder, compared to a non-exertional placebo intervention, suggesting a potential normalization of hypothalamic-pituitary-adrenal axis dysregulation.

Why this might work

Vibrating exercise shakes the body and makes muscles contract, which sends signals to the brain's stress control center. This lowers excess stress hormone levels in the morning, reduces inflammatory chemicals in the blood and brain, and allows the brain to produce more growth factors that repair and strengthen connections between mood-regulating neurons.

    This study is testing whether a special vibrating exercise helps teens with depression by changing their morning stress hormone levels — and it’s set up to measure exactly that. So far, the exercise helped reduce depression, which suggests it might also be fixing their stress system.
