Effect of Aureobasidium Pullulans Produced β-glucan on Musculoskeletal Biomarkers in Adults With Relative Sarcopenia

Not Applicable

Completed

• Conditions: Sarcopenia
• Interventions: Dietary Supplement: placebo group; Dietary Supplement: Aureobasidium pullulans produced β-glucan group

• Registration Number: NCT05106686
• Lead Sponsor: Pusan National University Yangsan Hospital

Brief Summary

The investigators conduct a randomized, double-blind, placebo-controlled study to investigate the effects of Aureobasidium pullulans produced β-glucan on muscle strength, muscle mass, and muscle function in adults with relative sarcopenia for 12 weeks.

Detailed Description

A previous study has indicated that Aureobasidium pullulans produced β-glucan may increase muscle mass and strength. Therefore, the investigators conduct a randomized, double-blind, placebo-controlled study to investigate the effects of Aureobasidium pullulans produced β-glucan 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 6 and 12 weeks of intervention. Eighty adults were administered either 1,000 mg of Aureobasidium pullulans produced β-glucan or a placebo each day for 12 weeks.
