A clinical workstream calibrated to elite rugby. Built around the modifiable biology that determines peak performance, contact recovery, neurological resilience and post playing trajectory. Calibrated to position. Calibrated to career stage. Calibrated to the women's and men's game.
Most chronic disease is the late expression of a single underlying biology, namely smouldering chronic inflammation, driven by metabolic dysfunction, deeply entangled with the gut microbiome. Addressed early, through what we eat, how we sleep and how we move, this biology is genuinely modifiable. The result is decades of energy, sharpness and capacity.
The published evidence on neurodegeneration in elite rugby is concrete. Russell et al 2022 (Glasgow) reported a fifteen-fold increase in motor neurone disease and a two-fold increase in dementia in former Scottish international rugby players. Butler et al 2025 (Nature) demonstrated neuron loss and inflammation in young athletes. Hiles-Murison et al 2021 documented blood-brain barrier disruption after subconcussive impact.
Anaerobic power, contact readiness, third-quarter capacity and cognitive sharpness across accumulated match minutes depend on mitochondrial function, glycaemic control, sleep architecture, omega-3 status and the cumulative inflammatory tone that sits below conventional screening.
Position-specific demands matter materially. A front row forward, a back row forward, a winger and a fly half carry different load profiles, different injury patterns and different post career trajectories. EPOCH calibrates to position alongside the existing performance model.
Rugby careers are short and the post career trajectory is steep. Cardiovascular, metabolic and neurological biology planning across retirement is the pillar that conventional pathways address least well.
The clinical work calibrated to elite rugby sits in three pillars. The integrated structure is what makes the Modified EPOCH Index calibration to elite sport materially different from population-level health screening.
Anaerobic power, contact readiness, sustained cognitive sharpness and endurance across accumulated match minutes including third-quarter capacity and decision making under fatigue. Mapped to mitochondrial function, the gut microbiome and mucosal immunity, glycaemic control, sleep architecture, omega-3 status and protein and leucine intake. Position-specific calibration.
Neurological resilience against subconcussive and concussive impact load, tendon and joint integrity, inflammatory baseline. Volumetric brain MRI integrated where clinically warranted. Anchored to the published evidence on metabolic optimisation as a parallel pathway in CTE risk mitigation.
The career arc itself, particularly the post playing trajectory. Cardiovascular and metabolic biology planning for the years after retirement. Neurological resilience sustained across the long arc. Quarterly Modified EPOCH Index retest extends beyond the playing career.
The Modified EPOCH Index is the proprietary longitudinal clinical instrument at the centre of every elite rugby engagement. Calibrated to athlete optimal references rather than to general population norms. The biomarker panel composition draws on clinically established markers selected for their published predictive value. The Index integration, optimal references, weights and scoring functions are proprietary clinical methodology and remain confidential.
The website is the public-facing layer. Executive summaries circulate to elite sport contacts under confidentiality framework once a conversation is live. Case studies sit one further step back, behind a confidentiality letter. All correspondence is treated in confidence.
Initial scoping conversations are by invitation. Senior medical and performance contacts at clubs, federations and academies are welcome to make written enquiry to enquiries@epochmetabolic.com or through the conversation form below.
