REBEL MIND: Applying Performance Science In and Out of the Emergency Department

Feb 18, 2026
Allyn Abadie, principal scientist at Arena Labs and former athletic trainer turned biomarker researcher. He discusses using wearable data and coaching to quantify stress and recovery. Topics include breath acetone as a metabolic marker, key recovery metrics like HRV and sleep, quick science-backed micro-recovery tools, and translating athletic performance principles to clinician well-being.

Episode notes
INSIGHT

Question Consensus Practices To Find Real Evidence

  • Pursue the 'why' behind practices rather than accepting them because they're consensus or logical.
  • Allyn's concussion research started by questioning a widely used graduated return-to-play protocol that lacked evidence.
INSIGHT

High Stakes Roles Share Physiologic Stress Despite Different Schedules

  • High-consequence jobs (athletic trainers, ER clinicians) share physiologic stress patterns even if schedules differ.
  • Translating athletic performance science to medicine requires adapting execution to clinical constraints.
ADVICE

Measure Few Metrics And Use Coachable Biofeedback

  • Track a few key biometrics (HRV, resting heart rate, sleep duration/consistency) to know what to improve.
  • Use coach-guided biofeedback that links those metrics to 5-minute, actionable interventions you can do on shift.
