An experimental test of resource recovery from physical and relaxation work break activities.

Actual resource replenishment, a defining part of the stress-recovery process, has hardly been studied. We address this gap in the literature within the context of work breaks to determine which resources are replenished relative to a pre-stressor baseline. Guided by conservation of resources theory and the effort-recovery model, we explored how two different break activities promoted recovery by looking at their effects on recovery experiences (relaxation, psychological detachment), psychological resources (self-regulatory capacity, energy), and an indicator of insufficient recovery (fatigue). In a sample of 160 college students, we experimentally induced a state of resource depletion via mentally demanding tasks and randomly assigned people to a physical (stationary bike) or relaxation (progressive muscle relaxation) recovery break activity. The relaxation activity resulted in higher psychological detachment and relaxation experiences, the physical activity resulted in higher energy levels, and there were no differences between the break activities for self-regulatory capacity or fatigue. Overall, post-break resource levels improved following recovery break activities. Energy levels returned to baseline (replenishment); self-regulatory capacity and fatigue improved beyond baseline (accumulation). These resource replenishment and accumulation findings further the development of recovery theory and help employees select a work break activity that better meets their resource-related needs.
