As the aging population is increasing substantially worldwide, extending the healthy life expectancy of older people has become a challenging issue. The structure and function of skeletal muscle decline with age, and this change has been shown to be involved in the development of various adverse health outcomes. In recent years, sarcopenia, a disease that is associated with age-related skeletal muscle mass loss and muscle weakness, has been attracting attention, and disuse muscle atrophy is also an important condition. For these diseases, it is recommended to increase exercise and physical activity, especially resistance exercise. In addition to conducting further research, it is necessary to widely disseminate information regarding the significance of exercise and physical activity as cost-effective interventions to the general public as well as health care professionals.
