A Study on the Physiological Composition, Morphology, and Muscle Function Characteristics of Elderly Male Individuals in Rural Areas Across Different Life Stages

Objectives This study was conducted to investigate changes in body composition, morphological aspects, and muscle function by life cycle in elderly people in rural areas. Methods 244 elderly people were divided into 4 groups. :50s (n=60), 60s (n=65), 70s (n=62), 80s (n=57). Body composition, morphology, and muscle function characteristics of the subjects were measured and analyzed. Results In terms of body composition, skeletal muscle mass and body mass index significantly decreased with age, and body fat percentage and extracellular water ratio significantly increased. IIn terms of morphological characteristics, bilateral thigh and calf circumferences, along with SMI, significantly decreased with increasing age. In terms of muscle function characteristics, as age increased, there was a significant decrease in bilateral grip strength, leg strength, and a significant increase in the ability to perform 5-chair rises. Conclusions From these results, it was suggested that elderly men in rural areas decrease muscle mass and increase body fat percentage in the body as they age, which reduces muscle strength and muscle function. This highlights the critical need for proactive physical management starting from middle age.
