This study primarily aimed to investigate effects of breaking up prolonged sitting with intermittent brisk walking in healthy young individuals on (1) post-trial human behaviours including energy intake and physical activity under free-living conditions and (2) cognitive performance in a simulated workplace environment.

In the laboratory, after consuming 1st meal, participants sat on a chair for 180 min. After 180 min, the 2nd meal was provided. After finishing the 2nd meal, participants sat on a chair for another 120 min. After data collection was completed in the laboratory, participants were asked to keep wearing the same pedometer and to record any food and liquid consumption for the rest of the day (until midnight) under free-living conditions.
In the laboratory, after consuming 1st meal, participants walked 2 min on a treadmill every 20 minutes for the following 180 min. For the remainder of the time participants sat on the chair. After 180 min, the 2nd meal was provided. After finishing the 2nd meal, participants continued 2 min of walking every 20 min for the following 120 min. After data collection was completed in the laboratory, participants were asked to keep wearing the same pedometer and to record any food and liquid consumption for the rest of the day (until midnight) under free-living conditions.
