Lifter Maladies

Caffeine vs Paraxanthine, Sleep Quality, and Common Lifter Maladies (Injuries, Blood Work, Apnea, Aging)

On Iron Radio, hosts Coach Phil Stevens and Dr. Lonnie Lowery (with Dr. Mike Nelson traveling) discuss a 2026 JISSN study on caffeine and its main metabolite paraxanthine in 14 male university rowers, finding the caffeine+paraxanthine combo improved 2,000m rowing performance versus placebo while caffeine-containing conditions worsened subjective sleep; they note key limitations including small sample size, subjective sleep measures, and unequal dosing (200 mg caffeine + 200 mg paraxanthine vs 200 mg of either alone). They then shift to “lifter maladies,” focusing on orthopedic issues (Phil’s MCL tear and training through injury), blood work and cholesterol swings, and the role of athlete compliance and monitoring versus gen pop. They also cover sleep apnea prevalence in large lifters, mental standards and training psychology, aging-related risks (ASCVD, prostate enlargement), and compensatory benefits like higher bone density and pain tolerance.
