cleaned final data that is between record getup time and sleep time |
MVPA is defined into two types: Long Bout MVPA and Sporadic MVPA_ Long Bout MVPA is defined as 10 consecutive minutes with METs>=3 (allowing 2 min below that threshold). Sporadic MVPA is defined as activities at any time with METS>=3 and they are not in Long Bout MVPA.
Highest METs values in 15 second/10 minutes are calculated by picking up the maximum METs values from the combined data with 15 second intervals and the data with 10 minutes intervals, respectively.
Total_light_time
Total light time: the total activity minutes minus the total MVPA hours
Total_MVPA_time
Total MVPA hours: the summation of the total Long Bout MVPA and total Sporadic MVPA durations
Total_MVPA_Long_Bout_time
Total MVPA long bout time: the summation of the total Long Bout MVPA durations
Total_mvpa_sporadic_time
Total MVPA sporadic time: the summation of the total Sporadic MVPA durations
