Summary

This study aims to evaluate the relationship between serum myostatin and irisin levels and bone mineral density and muscle strength in postmenopausal women. Participants will be grouped according to bone mineral density as normal, osteopenic, or osteoporotic. Serum myostatin and irisin levels will be measured, and muscle strength will be assessed using handgrip strength and the five times sit-to-stand test. The associations between biochemical and functional parameters will be analyzed.

Detailed description

This cross-sectional observational study aims to evaluate the relationship between serum myostatin and irisin levels and bone mineral density and muscle strength in postmenopausal women. Postmenopausal women aged between 50 and 65 years who meet the inclusion criteria will be enrolled in the study. Bone mineral density will be assessed using dual-energy X-ray absorptiometry (DEXA), and participants will be classified into three groups as normal, osteopenic, or osteoporotic according to T-scores. Serum myostatin and irisin levels will be measured from venous blood samples collected after overnight fasting. Muscle strength will be evaluated using handgrip strength, and functional performance will be assessed with the five times sit-to-stand test. Demographic and clinical characteristics of the participants will also be recorded. The relationships between serum myostatin and irisin levels and bone mineral density and muscle strength parameters will be analyzed using appropriate statistical methods.
