Resistance Training to Prevent Muscle Loss During Treatment With Tirzepatide
A Phase IV, Randomized Controlled Trial to Evaluate the Effects of Resistance Training Versus Usual Care on Thigh Muscle Volume During Treatment With the Dual GIP/GLP-1 Receptor Agonist Tirzepatide in Adults With Obesity
Technical University of Munich
150 participants
Sep 7, 2026
INTERVENTIONAL
Conditions
Summary
Incretin-based pharmacotherapies induce significant weight loss and represent a paradigm shift in obesity treatment. However, particularly fast weight loss may be accompanied by a significant loss of muscle mass, which is associated with a reduced metabolic rate at rest and during physical activity, increased insulin resistance, limited mobility, and potential long-term adverse effects. The aim of this clinical trial is to examine the effects of resistance training versus standard of care on contractile thigh muscle volume in patients receiving the dual glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1) receptor agonists 'tirzepatide'.
