This course focuses on sarcopenia in older adults, including its definition, assessment indicators, strategies for maintaining muscle strength and mass, and the role of nutritional supplementation in prevention. The first section introduces the mechanisms underlying sarcopenia, such as loss of muscle mass, reduced muscle strength, and functional decline. Factors including neuromuscular degeneration, hormonal changes, chronic inflammation, inadequate nutrition, and insufficient physical activity are discussed. Students are also introduced to widely used assessment tools, such as handgrip strength, gait speed, skeletal muscle mass measurements (SMM/ASM), and body composition assessments using DXA or BIA, providing both clinical and community-based evaluation perspectives. The second section highlights the importance of maintaining muscle mass and strength in older adults, emphasizing the role of resistance training in stimulating muscle protein synthesis, as well as the benefits of balance and functional training in fall prevention and preserving independence. The final section focuses on protein intake and nutritional supplementation, covering daily protein requirements, the role of leucine and essential amino acids, commonly used supplements such as BCAAs and vitamin D, nutrient timing, and dietary strategies. The synergistic effects of combining exercise and nutrition interventions are also explored. Overall, the course integrates scientific evidence, elder-friendly approaches, and interdisciplinary perspectives, equipping students with essential knowledge and practical skills for the prevention of sarcopenia.
