Study Finds Muscle Strength Linked to Lower Depression Risk in Women
A recent study published in the Journal of Affective Disorders has revealed a significant association between muscle strength and a reduced risk of depression, particularly in women. Researchers analyzed data from over 341,000 adults aged 37 to 73, using genetic predispositions to muscle strength and cardiorespiratory fitness to assess mental health outcomes. The study found that higher grip strength, used as a proxy for overall muscle strength, was linked to a lower risk of depression. Specifically, for every 0.1 kilogram increase in grip strength per kilogram of body weight, participants had a 14 percent lower risk of depression. The study did not find a similar link for cardiorespiratory fitness. The findings suggest that strength training could be an effective adjunct to existing depression treatments.
