Effects of Multimodal Physical and Cognitive Fitness Training on Sustaining Mental Health and Job Readiness in a Military Cohort

Drawing on the emerging area of workplace sustainability, this study sought to measure the effects of multimodal physical and cognitive fitness training on sustaining mental health and job readiness via impacts on subjective burnout, mental wellbeing, and resilience in a military cohort. Volunteer participants were block randomised into either a standard 4-week resilient mind program (RMP) intervention or an RMP combined with self-paced functional imagery practice (RMP+FI). Self-reported burnout, mental wellbeing, and resilience were measured at baseline and at the end of the 4-week intervention using the Maslach Burnout Inventory-General Survey (MBI-GS), Brief Resilience Scale (BRS), and the World Health Organization’s WHO-5 Well-Being Index (WHO-5), respectively. A total of 78 participants were enrolled in the study and 72 (92%) completed the program. Repeated measures ANOVAs showed significant effects of the RMP intervention, with both the RMP and RMP+FI groups reporting improved resilience (F(1, 70) = 13.08, p < 0.001, partial ω 2 = 0.00086) and mental wellbeing (F(1, 70) = 41.86, p < 0.001, partial ω 2 = 0.36). Both groups also reported improved burnout markers for professional efficacy (F(1, 70) = 6.25, p < 0.002, partial ω 2 = 0.02), as well as reduced emotional exhaustion (F(1, 70) = 31.84, p < 0.001, partial ω 2 = 0.02) and job cynicism (F(1, 70) = 8.80, p < 0.005, partial ω 2 = 0.005). The FI practice produced no significant improvement in the RMP-only condition. Our results support the efficacy of RMP intervention in reducing burnout symptoms and improving self-reported mental wellbeing and resilience in a cohort of serving Navy aviators.
