摘要：Achieving military mission objectives requires high levels of performance from Airmen who operate under extreme physical and cognitive demands. Thus, there is a critical need to establish scientific interventions to enhance physical fitness and cognitive performance—promoting the resilience of Airmen and aiding in mission success. We therefore conducted a comprehensive, 12-week randomized controlled trial in active-duty Air Force Airmen (n = 148) to compare the efficacy of a multimodal intervention comprised of high-intensity interval aerobic fitness and strength training paired with a novel nutritional supplement [comprised of β-hydroxy β-methylbutyrate (HMB), lutein, phospholipids, DHA and selected micronutrients including B12 and folic acid] to high-intensity interval aerobic fitness and strength training paired with a standard of care placebo beverage. The exercise intervention alone improved several dimensions of physical fitness [strength and endurance ( 8.3%), power ( 0.85%), mobility and stability ( 22%), heart rate (− 1.1%) and lean muscle mass ( 1.4%)] and cognitive function [(episodic memory ( 9.5%), processing efficiency ( 7.5%), executive function reaction time (− 4.8%) and fluid intelligence accuracy ( 19.5%)]. Relative to exercise training alone, the multimodal fitness and nutritional intervention further improved working memory ( 9.0%), fluid intelligence reaction time (− 7.7%), processing efficiency ( 1.8%), heart rate (− 2.4%) and lean muscle mass ( 1.5%). These findings establish the efficacy of a multimodal intervention that incorporates aerobic fitness and strength training with a novel nutritional supplement to enhance military performance objectives and to provide optimal exercise training and nutritional support for the modern warfighter.
