Thread on exercise and mental health and potential considerations for COVID-19:
1. Inducing sedentary behaviour in healthy people, can increase depression after as little as 7 days.
Need messaging to replace sedentary time w any PA https://www.ncbi.nlm.nih.gov/pubmed/27492908

2. Consider mental health / mental illness continuum. Exercise can be an effective component of treatment
AND
as a prevention strategy regardless of quadrant.
Required messaging and support will likely differ.

3. As little as 60mins of physical activity per week can prevent up to 17% of incident cases of depression

With robust evidence from genetic studies

4. What about the mental health of first-responders and workers on 'front-line'
Decline in physical activity over time is related to symptoms of PTSD. More severe symptoms = less PA.
Could we prevent some cases of PTSD by keeping people active?

Anxiety

6. Evidence for exercise as a part of treatment for people living with mental illness?
Umbrella review by @Garcia__AF of 27 systematic reviews (152 individual RCTs)
https://www.ncbi.nlm.nih.gov/pubmed/31541410
Also guidelines from international orgs including @EP_Editors

Don't focus on modality (type) or intensity, rather duration and overall volume is
, especially for sedentary people or those new to exercise

9. We don't have to 'get sweaty' in order to experience mental health benefits
Resistance training (RT) (muscle exercises
) can be just as effective (relevant during lockdown)
