In this study, virtual RCTs (Randomized Controlled Trials) with various exercise and nutrition interventions were conducted in randomly selected community-living population who have been followed up for over 15 years, aiming to develop strategies for the prevention of sarcopenia, physical and psychological frailty. Physical activity of 8,000 walking steps or more per day, exercise of moderate intensity or more (more than 3 Mets) for more than 15 minutes, and 2,000 kcal or more total energy expenditure were useful for prevention of sarcopenia. Similar results were obtained for physical prefrailties, depression, and cognitive prefrailties. A combination of aerobic exercise like walking and moderate or higher intensity exercise may be useful. However, nutritional intervention was less effective, and the importance of exercise intervention was revealed.
