[Transdisciplinary Approach for Sarcopenia. Physical activity and exercise training for prevention and treatment of sarcopenia].

The general outline of an exercise prescription for older adults with sarcopenia is aimed at improving their muscle strength and walking ability and increasing their muscle mass. Various types of resistance training (RT) can effectively increase muscle mass and strength even when the older individual's body weight is the only load and no special instruments such as expensive machines or heavy dumbbells are used. To effectively increase muscle mass and strength, individuals must perform at least one to two RT exercises on both the upper and lower extremities and the trunk two to three times per week for more than three months. Gait training is essential for improving walking ability. Although aerobic exercises typically contain gait training, they require an exercise intensity of greater than 60% of maximum oxygen uptake to effectively improve walking ability. In addition, we should remember that the effect of exercise training is maintained only by continuing the exercise program regularly over the long-term.
