Abstract: With the increasing global aging trend, sarcopenia has become one of the important health issues affecting the elderly population. The loss of muscle strength not only significantly reduces quality of life, but also increases the risk of falls, fractures, and long-term care dependency. Therefore, effective ways to promote muscle strength growth have become the focus of current sports science and clinical medicine research. Resistance training, as a widely used exercise method to enhance muscle strength, plays an important role in improving muscle health and slowing down age-related muscle loss. This paper discusses the molecular biological mechanism of muscle strength increase in resistance training under exercise nutrition intervention. Resistance training has long been recognized as an effective strategy to increase muscle strength and mass, but the role of sports nutrition in optimizing these outcomes is increasingly important. By examining key molecular pathways such as mTOR, AKT, and NF-κB, this study highlights how various nutritional interventions such as protein, leucine, ω-3 fatty acids, and carbohydrates can synergistically enhance the effects of resistance training.
