Sarcopenia is defined as an age-related reduction in muscle mass and performance. Some of the most important risk factors include advanced age, malnutrition, and sedentary lifestyle. The aim of this study was to investigate the association of food intake and physical activity with body composition, muscle strength, and muscle function in a cross-sectional study of postmenopausal women. This analysis gave a positive association between physical activity and handgrip strength, calorie intake and muscle function, protein intake and fat-free mass percentage, and total fat intake and fat mass percentage. In addition, there were negative associations found between carbohydrate intake and muscle function, as well as total fat intake and fat-free mass percentage. This chapter presents a protocol for the study setup along with measurements of physical activity, handgrip strength, nutrient intake, and fat-free mass percentage.
