First seen Aug 03, 2026 · Last updated Aug 04, 2026 · Updated 1 time
Summary
This study looks at how athletes who regularly lose and regain weight to meet competition categories experience changes in metabolism, body temperature, and body composition. Researchers will track 48 athletes through periods of weight maintenance, loss, and regain, using body temperature monitors and body scans. The goal is to understand the long-term health impacts of weight cycling and find ways to protect athletes from potential metabolic issues.
