Someone suggested I split off a new thread from this other thread for discussing body position tracking specifically, which seems like a good idea. Chris Armstrong from OMF brought up a device called activPAL a few months ago: Some info on activPAL: It's a device that is attached to the...

Abstract We measured physical activity after strenuous exercise in 20 women with chronic fatigue syndrome (CFS), compared to 20 sedentary healthy volunteers who exercised no more than once per week. Activity was measured for 2 weeks using a portable waist-worn vertical accelerometer. After the...

Abstract Importance The severity of viral infections can vary widely, from asymptomatic cases to complications leading to hospitalizations and death. Milder cases, despite being more prevalent, often go undocumented, and their public health burden is not accurately estimated. Objective To...

"Visible tracks your post-viral illness so you can manage your activity, avoid relapse and improve your health." https://makevisible.co/ There's not a lot of detail on the website - it seems to be focused on heart rate monitoring and tracking of symptoms.

Abstract Physical activity is defined as any bodily movement produced by skeletal muscles that results in energy expenditure. The benefits of physical activity for health maintenance have been well documented, especially in the prevention and management of chronic diseases. Therefore, accurate...
