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
