This study aimed to compare the effects of single-set versus multiple-set resistance training on neuromuscular performance and muscle morphology in sedentary men. Participants were randomly assigned to a single-set training group, a multiple-set training group, or a non-training control group. The intervention consisted of a structured resistance training program performed over a defined training period, while the control group maintained their usual lifestyle without structured exercise. Neuromuscular performance outcomes included maximal strength and functional performance measures, and muscle morphology was assessed using appropriate imaging and anthropometric methods. The findings of this study are intended to contribute to the understanding of optimal resistance training volume for improving neuromuscular adaptations in previously untrained individuals.
