IPEN Adolescent Accelerometer Data Collection Guidelines
Epoch:
Recommendation is to collect data with the shortest epoch your memory/battery
will allow (for the GT1M & GT3X)
Epoch will be applied during or post-download with GT3X+
Aggregate data to 30 seconds for IPEN (for consistency with data already collected)
Kelli L. Cain, San Diego May 2014
use 30 second epoch
for pooled data set
