Irisin has been identified as a novel myokine that drives brown-fat-like conversion of white adipose tissue. In this cross-sectional study, the researches investigated whether serum irisin levels are decreased in patients with sarcopenia compared with control subjects with normal muscle mass, and assessed the association between serum irisin levels and various metabolic parameters.


Study Type: Observational
Study Design: Observational Model: Cohort
Time Perspective: Cross-Sectional

Further study details as provided by Korea University:

Primary Outcome Measures:
  • Serum concentration of irisin in the subjects with sarcopenia [ Time Frame: 12 week ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • The relationship of serum irisin levels with lipid profiles [ Time Frame: 12 week ] [ Designated as safety issue: No ]
  • The relationship of serum irisin levels with skeletal muscle mass index [ Time Frame: 12 wks ] [ Designated as safety issue: No ]
