Differential efficacy of physical exercise and mindfulness during lunch breaks as internal work recovery strategies: a daily study

ABSTRACT This study aims to identify whether daily activities during the lunch break, performed before eating, are associated with improvements in several indicators related to recovery from work stress. No existing studies examine the daily effects of sitting mindfulness meditation and aerobic physical exercise practiced during lunch break as daily internal work recovery activities. This three-armed randomized controlled trial was carried out over 22 working days with service sector workers (n = 94, age mean, 46.8) The RCT was registered in ClinicalTrials.gov, Identifier: NCT03728062. The mindfulness group received a mindfulness-based intervention (sitting meditation), while the physical exercise group practiced an aerobic exercise program with the same time intervals as the mindfulness group (15–30 minutes); the third group was the control group. We measured daily effects on fatigue, psychological detachment, sleep quality, stress symptoms, and attention problems. Measurements of daily variables were collected through an ad hoc App. Growth curve analysis reveals that mindfulness and physical exercise can effectively reduce fatigue, stress boschphysicalBosch physical exercise significantly improved sleep quality.
