Table 2: Significant Findings Only. Time: For all interventions, participants had significant (\(p<0.05\)) declines in the number of correct responses on the distractor tasks (\(\Delta 0.58\)) and the percent of correct responses on the RVIP tertiary task (\(\Delta 4.94\)). All participants also had significantly slower reaction times (\(\Delta 0.53\) s), RVIP primary task (\(\Delta 0.04\) s), and on both the congruent (\(\Delta 0.07\) s) and incongruent (\(\Delta 0.11\) s) aspects of the Stroop task. All participants also reported significant decreases in feelings of vigor (\(\Delta 0.95\)), decreases in state physical energy (\(\Delta 12.94\)), but increases in state mental energy (\(\Delta 12.97\)) and the motivation to perform mental tasks (\(\Delta 23.05\)). Significant increases in feelings of fatigue (\(\Delta 0.92\)) were also reported; however, when measuring fatigue using the state/trait mental and physical energy and fatigue questionnaire, there were significant improvements in state physical (\(\Delta 27.72\)) and mental (\(\Delta 27.36\)) fatigue over the course of the protocols.
