Exercise-induced Changes In Circulating Follistatin And GDF-15 Are Intensity- And Duration-dependent

Follistatin inhibits the actions of the TGFβ family to oppose inhibition of skeletal muscle growth, whereas growth and differentiation factor (GDF) 15 may inhibit muscle growth. The PURPOSE of this project was to determine if predominately aerobic exercise can induce changes in concentrations of circulating follistatin and GDF-15, and if these changes are dependent on exercise intensity and/or duration. METHODS: Fifteen recreationally trained...
