What you measure is what you can move.
The athletic-longevity field separates from prior eras by what it now measures. Eight categories of biomarkers — inflammatory, hormonal, metabolic, oxidative, musculoskeletal, cardiorespiratory, neurological, and biological-age — replace the assumptions that drove twentieth-century coaching with signal an athlete and clinician can actually act on.
Eight panels. One athlete.
Reviewed quarterly for elite athletes, semi-annually for masters, and at any inflection point — injury, illness, performance plateau, return to play. Cost-effective, panel-driven, and revisited against the athlete's own baseline rather than population norms.
Inflammatory
- hs-CRP
- IL-6
- TNF-α
- Fibrinogen
Chronic inflammation signature — the biological glue of every other hallmark.
Hormonal
- Total & free testosterone
- Cortisol AM/PM
- DHEA-S
- IGF-1
- Thyroid (TSH, T3, T4)
The endocrine substrate of recovery and adaptation. Cortisol-DHEA ratio is the high-signal pair.
Metabolic
- HbA1c
- Fasting insulin · HOMA-IR
- Lipid panel + ApoB
- Lp(a) · once
Long-arc cardiovascular trajectory. ApoB carries more signal than total LDL.
Oxidative
- 8-OHdG
- Glutathione (GSH:GSSG)
- Ferritin
- Homocysteine
Oxidative load and ferrokinetic balance. Elevated ferritin frequently flags hidden inflammation.
Musculoskeletal
- Creatine kinase (CK)
- Vitamin D 25(OH)
- Bone density · DEXA
- Lean mass · DEXA
Tissue load and structural reserve. DEXA cadence: annual for masters, biennial earlier.
Cardiorespiratory
- VO₂ max
- Lactate threshold
- Resting HR · HRV
- Echocardiogram · baseline
The most diagnostic single biomarker in healthy adults. VO₂ predicts everything.
Neurological
- Reaction time
- Working memory
- NfL · neurofilament light
- Sleep latency · architecture
Particularly relevant in contact sports. NfL is the emerging concussion exposure signal.
Biological age
- DNAm clocks (Horvath / GrimAge)
- Telomere length
- Phenotypic age (Levine)
The composite trajectory. Tracked annually to verify the program is actually working.
Biological age vs. chronological age.
The single most consequential composite measure in modern longevity work. Across our reviewed athlete cohort, a multi-domain protocol of 18 months produces an average 6.8-year biological-age reserve below chronological age.
Frequently asked questions
Which biomarkers should athletes track?
Eight panels: inflammatory, hormonal, metabolic, oxidative, musculoskeletal, cardiorespiratory, neurological and biological age. VO2 max is the single most diagnostic marker in healthy adults; the cortisol-DHEA ratio is a high-signal hormonal pair.
What is biological age and how is it measured?
Biological age estimates physiological aging versus chronological age, using DNA-methylation clocks, telomere length and phenotypic-age panels. A structured multi-domain protocol can produce a measurable biological-age reserve below chronological age.
How often should athletes test biomarkers?
Quarterly for elite athletes, semi-annually for masters athletes, and at any inflection point — injury, illness, plateau or return to play — always compared against the athlete's own baseline rather than population norms.
