Effectiveness of Combined GLP-1/GIP Dual Agonist Therapy and Structured Exercise on Skeletal Muscle Morphology, Quality, and Physical Function in Overweight and Obese Individuals
Effectiveness of Combined GLP-1/GIP Dual Agonist Therapy and Structured Exercise on Skeletal Muscle Morphology, Quality, and Physical Function in Overweight and Obese Individuals: a Randomized Controlled Trial Protocol
Panoramica dello studio
Stato
Intervento / Trattamento
Descrizione dettagliata
Pharmacologically induced weight loss with glucagon-like peptide-1 (GLP-1)/ glucose-dependent insulinotropic polypeptide (GIP) receptor agonists such as tirzepatide is associated with significant reductions in lean body mass, raising concerns regarding muscle function and long-term outcomes. Resistance exercise is the most effective intervention to preserve muscle mass during weight loss; however, evidence combining these approaches is limited.
This study is a prospective, two-center, single-blinded, randomized controlled trial designed to evaluate whether structured resistance exercise enhances muscle preservation and functional outcomes in individuals receiving tirzepatide therapy.

Cosa sta misurando lo studio?
Misure di risultato primarie
Misura del risultato |
Misura Descrizione |
Lasso di tempo |
|---|---|---|
|
Change in muscle thickness
Lasso di tempo: Baseline, 12 weeks, 24 weeks
|
Muscle thickness of the thigh (quadriceps femoris) will be assessed using a portable ultrasound and will be presented in millimeters (mm).

|
|
Nutritional status (3-day food record)
Lasso di tempo: Baseline, 12 weeks, 24 weeks
|
Dietary intake will be assessed at baseline, 12 weeks, and 24 weeks using 3-day food records (two non-consecutive weekdays and one weekend day).
