Dietary Strategies for Neuromuscular Function, Exercise Performance, and Training Adaptations

Neuromuscular function is a fundamental determinant of exercise performance and training adaptations. The capacity to generate and sustain muscular force and power depends on the interaction among neural activation, excitation-contraction coupling, muscle metabolism, and substrate availability. Fatigue-related disturbances within these systems can reduce strength, power, rate of force development, and repeated high-intensity exercise performance while potentially affecting adaptations to chronic exercise training. Although dietary strategies may influence these responses, the physiological mechanisms through which nutrition affects neuromuscular performance and training adaptations remain unclear.A growing body of research has examined how nutritional interventions, including macronutrient manipulation, nutrient-timing strategies, established ergogenic aids, novel dietary supplements, and multi-ingredient formulations, affect muscular performance, fatigue, and training adaptations. Research findings, however, remain inconsistent for many interventions. Differences in intervention type, composition, dosage, timing, participant characteristics, exercise protocols, and outcome measurements complicate comparisons across studies. Moreover, performance outcomes are often reported without complementary physiological assessments that could clarify whether an intervention affects neural activation, muscular contractile function, substrate utilization, fatigue development, recovery, or adaptations to exercise training.This Research Topic aims to advance understanding of how acute and chronic dietary strategies influence neuromuscular function, exercise performance, and training adaptations. Particular interest will be given to studies integrating performance outcomes, such as muscular strength and power, with physiological measures such as electromyography, muscle oxygenation, neuromuscular stimulation, and force- or torque-time characteristics. Key questions include whether dietary interventions can enhance neural or muscular function, delay central or peripheral fatigue, preserve force and power during repeated high-intensity exercise, accelerate neuromuscular recovery, or augment adaptations to exercise training. Studies examining whether dietary interventions augment neuromuscular adaptations to resistance training are also encouraged. The collection also seeks to identify individual and methodological factors that may explain variability across studies and improve the translation of findings into evidence-based practice.We welcome articles addressing, but not limited to, the following themes:1. Acute and chronic effects of dietary strategies on neuromuscular function2. Effects of dietary supplements and ergogenic aids on muscular strength, power, and fatigue3. Influence of macronutrient composition, substrate availability, and nutrient timing on exercise performance and training adaptations4. Physiological effects of single-ingredient and multi-ingredient formulations5. Nutritional influences on central and peripheral mechanisms of fatigue6. Dietary strategies for repeat-sprint, resistance, and other forms of exercise7. Combined effects of dietary strategies and resistance training interventions, including low-load blood flow restriction training, on neuromuscular adaptations8. Neuromuscular activation, muscle oxygenation, blood flow, and metabolic responses to nutritional interventions9. Sex-, training status-, and population-related differences in physiological responses10. Inter-individual variability in responses to supplementation11. Methodological innovations and best practices for evaluating dietary interventions and sports supplements12. Safety, efficacy, and practical translation of dietary strategies for exercise performance and training adaptationsFurthermore, we encourage submissions of various article types, including original research, clinical trials, and systematic reviews, to deepen our understanding and expand the scope of research within this field.
