Overview
This article reviews a longitudinal case study tracking the body composition of Mijain Lopez, the Cuban Greco-Roman wrestler who won five consecutive Olympic gold medals in the 130 kg category, during his preparation for Paris 2024.

Why This Study Matters
Lopez was 41 years old at Paris 2024. After retiring following Tokyo 2021, he returned after two and a half years away. Starting weight approximately 150 kg, needing to reach 130 kg.
Study Design
- Subject: Cuban athlete, aged 41.4, height 194.4 cm
- Measurements: January, June, July 2024
- Methods: ISAK anthropometry plus bioelectrical impedance analysis
Three-Phase Protocol
- Phase 1 Jan-Jun: Stabilization, protein 1.6-2.0 g/kg/day, no competition
- Phase 2 Jun-Jul: Active reduction, protein 2.0-2.2 g/kg/day, fat reduced
- Phase 3 Jul-Aug: Final cut, details not disclosed
Key Results Phase 2 (36 days)
- Body weight: -6.1%
- Muscle mass: -2.2% (preserved)
- Subcutaneous fat: -13.5%
- Phase angle: 6.1 to 5.6 degrees (normal: 5-7)
- ICW/ECW ratio: 1.22 to 1.39 (optimal: 1.35-1.45)
Body Fat Standards for Super-Heavyweights
ACSM recommends 5% minimum body fat. For super-heavyweight athletes, the authors argue 13% is more realistic.
Why Phase 3 Data Was Not Published
How Lopez reduced from 138.5 kg to 130 kg was not disclosed, protected as national procedure by the Cuban National Institute of Sports Medicine.
Summary
- At 41, Lopez reduced from 150 kg to 138.5 kg while preserving muscle mass
- Cellular health indicators remained normal throughout
- 13% body fat proposed as minimum for super-heavyweights
- Competition-free preparation contributed to metabolic stability
