Muscular Sarcoidosis
Conditions
Brief summary
The investigators conduct a randomized, double-blind, placebo-controlled study to investigate the effects of the fermented oyster extract on muscle strength, muscle mass, and muscle function in healthy adults for 12 weeks.
Detailed description
Previous studies have indicated that fermented oyster extract may have the ability to prevent skeletal muscle atrophy. Therefore, the investigators conduct a randomized, double-blind, placebo-controlled study to investigate the effects of the fermented oyster extract on muscle strength, muscle mass, and muscle function in healthy adults; the safety of the compound are also evaluate. 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 4 and 12 weeks of intervention. Fifty-four healthy adults were administered either 1,200 mg of fermented oyster extract or a placebo each day for 12 weeks;
