A previous study has indicated that silkworms (Bombyx mori L.) pupae extracts may increase muscle mass and strength. Therefore, the investigators conduct a randomized, double-blind, placebo-controlled study to investigate the effects of silkworms (Bombyx mori L.) pupae extracts on muscle strength, muscle mass, and muscle function in adults with relative sarcopenia; the safety of the compound are also evaluated. The Investigators examine the peak torque/body weight at 60°/s knee extension, handgrip strength, skeletal muscle mass, physical performance, and metabolic parameters at baseline, as well as after 12 weeks of intervention. Fifty four adults were administered either 2,400 mg of silkworms (Bombyx mori L.) pupae extracts or a placebo each day for 12 weeks.
