Biomarkers

Panels

This panel evaluates glucose control, lipid balance, and metabolic resilience. It helps identify early warning signs of energy dysregulation, overtraining, or long‑term health risks.

  • Supports safe fueling and recovery strategies
  • Flags insulin resistance, dyslipidemia, or metabolic stress
  • Guides nutrition timing and macronutrient balance
  • Provides context for fatigue, weight changes, and adaptation

🚨 Red‑Flag Results — Seek Medical Review: Fasting glucose >6.1 mmol/L • HbA1c >6.5% • Triglycerides >2.0 mmol/L • ALT/AST >2× upper limit

⏱ When to Test

  • Morning, fasted (8–12 h, water only)
  • At least 48 h after heavy training or racing
  • Well hydrated, no acute illness
  • Recommended scenarios: start-of-base, pre/post camp, quarterly check, unexplained fatigue or weight change

🧬 Athlete Targets

Marker Standard Range Athlete Target Notes
Fasting Glucose 3.9–5.5 mmol/L 4.5–5.2 mmol/L Stable energy availability
HbA1c <6.0% 5.0–5.4% Long‑term glucose control
Triglycerides <1.7 mmol/L <1.2 mmol/L Metabolic efficiency
HDL Cholesterol >1.0 mmol/L >1.3 mmol/L Protective lipid profile
LDL Cholesterol <3.0 mmol/L <2.5 mmol/L Lower cardiovascular risk
ALT / AST <40 U/L <30 U/L Liver stress marker

🧭 Decision Protocol

  1. Check fasting glucose: >6.1 mmol/L → escalate to doctor.
  2. Review HbA1c: >6.5% → diabetes threshold; 5.5–6.4% = pre‑diabetes risk.
  3. Assess lipids: High triglycerides or low HDL → metabolic stress.
  4. Check liver enzymes: ALT/AST >2× upper limit → escalate.
  5. Integrate with symptoms: fatigue, weight change, poor recovery → flag earlier.

🧍 Athlete Self‑Check

  • Unexplained weight gain or loss
  • Persistent fatigue despite adequate sleep
  • Cravings or energy crashes between meals
  • Slow recovery from normal training

If these symptoms persist alongside abnormal labs → escalate to medical review.

🗒 Coach Notes

  • Always interpret glucose and lipid results in the context of nutrition logs and training load.
  • Flag fasting glucose >5.5 mmol/L or HbA1c trending upward for medical review.
  • Look for patterns: repeated high triglycerides after camps may signal inadequate recovery or fueling.
  • Encourage athletes to track energy levels, mood, and sleep alongside labs.
  • Do not recommend supplements or medications — escalate to medical staff.

Reminder: Protect athlete health first; performance adjustments come only after medical clearance.

🛠 Role-Based Actions

Role Actions
🧑‍🎓 Rider • Maintain balanced meals with complex carbs, lean protein, healthy fats
• Avoid excessive processed sugar
• Track energy levels and recovery
• Report persistent fatigue or weight change
🧑‍🏫 Coach • Adjust training load if fatigue or poor recovery present
• Flag abnormal glucose or lipid results
• Encourage nutrition logging
• Coordinate re‑test in 8–12 weeks
🧑‍⚕️ Doctor / Nutritionist • Confirm diagnosis if abnormal
• Investigate insulin resistance or dyslipidemia
• Prescribe interventions if needed
• Monitor long‑term metabolic health

🔁 Feedback Loop

  • Re‑test 8–12 weeks after intervention or nutrition change
  • Escalate if:
    • Fasting glucose remains >5.5 mmol/L
    • HbA1c continues to rise
    • Triglycerides remain >1.7 mmol/L
    • ALT/AST remain elevated
    • Symptoms persist despite lifestyle adjustments

Tip: Record test date and planned re‑test date for accountability.

Ranges and decision logic adapted from WHO, ADA (American Diabetes Association), ESC/EAS lipid guidelines, and peer‑reviewed sports medicine literature. This panel is designed for transparency and athlete safety — always escalate red‑flag results to a qualified medical professional.
