Hello, I used an actigraph GT3X for 7days with 15-16 year old athletes. I'm looking to determine their PA level, determine their sedentary time and in the second time estimate their energy expenditure. I can't decide on the cut offs to use. I was going to start from the Vector Magnitude (in cpm). Thank you for your help!

Hello Christoph,
Thank you for your feedback! The papers seem to specify that the cutt points should be chosen according to the wearing zone of the accelerometer and the age of the participants. I am having trouble finding cutt points in count/mint that combine wrist wear with age (15-16 years)
Kind regards,
Lisa
