Objectives: This study aimed to evaluate the current research landscape, identify emerging areas of interest, and provide scientific insights for further research in exercise and nutrition for sarcopenia. Methods: A comprehensive bibliometric analysis was conducted using publications retrieved from the Web of Science Core Collection and SCOPUS between January 1, 2005 and January 1, 2025, focusing on exercise and nutritional interventions for sarcopenia. CiteSpace and VOSviewer were employed to visualize research trends through analysis of annual publications, keyword evolution, journal contributions, author networks, country/regional distributions, institutional collaborations, citation patterns, and high-frequency terminology. Results: The analysis included 886 publications demonstrating a consistent upward trajectory in annual output. Geographical shifts revealed a transition of research leadership from traditional centers in the United States and Europe to emerging Asian contributors, particularly China. High-frequency keywords analysis identified core concepts including "Skeletal Muscle" (Betweenness Centrality Degree, BCD 0.13), "Resistance Exercise" (BCD 0.11), and "Muscle Strength" (BCD 0.13), with nutritional components "Dietary Protein" (BCD 0.19), "Vitamin D" (BCD 0.14), and "Amino Acids" (BCD 0.18) forming distinct research clusters. Cluster analysis revealed five thematic domains: Protein Metabolism (Cluster 1), Body Composition Assessment (Cluster 2), Resistance ...
