Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The aim of this study is to investigate the effect of endurance training performed with a bicycle ergometer at different ambient temperatures on the amount of fat tissue and fat tissue metabolism in overweight and obese women.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This study will examine the effects of 12 weeks of endurance training on a bicycle ergometer at thermoneutral and slightly cold ambient temperatures on body composition, subcutaneous and visceral fat tissue thickness, and levels of irisin, leptin, adiponectin, apelin, IL-6 and FGF-21 in the blood of overweight and obese women.
