About this trial
The CONCRET-SARCOPA trial is a 12-week, double-blind, randomized controlled study designed to evaluate the efficacy of creatine HCl supplementation in older adults with sarcopenia. The trial investigates whether daily creatine HCl improves body composition, enhances functional muscle and cognitive performance, and favorably alters key blood biomarkers associated with muscle health and metabolic status. Additionally, the study assesses changes in tissue creatine levels using non-invasive and biochemical methods to clarify mechanistic responses to supplementation. Findings from this trial will provide critical evidence on the therapeutic potential of creatine HCl as a targeted nutritional strategy for managing sarcopenia in the geriatric population.

Trial outcomes
Primary outcomes
Hand-grip strength
Handgrip strength quantifies maximal voluntary force generated by the hand using a dynamometer, serving as a simple, reliable indicator of overall muscle function and sarcopenia severity.
Secondary outcomes
Senior fitness test score
The Senior Fitness Test score reflects aggregated performance across multiple functional tasks, providing a quantifiable index of an older adult's overall physical capability, mobility, and age-related fitness status.
Mini-Mental State Examination Score
The Mini-Mental State Examination score quantifies global cognitive function by assessing orientation, memory, attention, language, and visuospatial abilities, offering a validated measure for detecting cognitive decline in older adults.
Appendicular muscle mass
Appendicular muscle mass quantifies lean soft tissue in arms and legs serving as a key indicator of skeletal muscle quantity and sarcopenia-related muscle depletion.
