Hi everyone, I am about to start a new project. I want to monitor physical activity, sedentary and sleep time of university students with an accelerometer. Which accelerometer would be the best for time-based measurement and why would you recommend the product?
Thanks
I would recommend the ActiGraph series to record raw acceleration data, which is converted into a variety of objective activity and sleep measures using publicly available algorithms developed and validated by members of the academic research community. Available measures include: Raw Acceleration (G's) Activity Counts, Energy Expenditure, MET Rates, Steps Taken, Physical Activity Intensity, Activity Bouts, Sedentary Bouts, Body Position, Sleep Latency, Total Sleep Time, Wake After Sleep Onset, Sleep Efficiency.
I used data from these devices for sleep analyses and my colleageus - for activity measures. Device was used in many other epidemiological studies in many countries. Device is easy to use, placed on waist and easy to analyse. In my opinion, software uses Cole-Cripke algorhythm for sleep analyses which was not validated for waist position (actually for wrist).
thank you for comprehensive answer Mikhail Bochkarev. Where can i find the algorythms to check?
