Combat Sports Training Demands
Boxing, MMA, wrestling, judo, BJJ—all share unique challenges:
High-intensity sparring: - Maximum CNS stress - Repeated impacts and trauma - Adrenaline spikes
Technical drilling: - Can be moderate or intense depending on pace - Often underestimated in terms of fatigue
Strength and conditioning: - Additional load on top of skill work - Must be balanced with technical training
Weight management: - Weight cuts create massive HRV stress - Recovery from cuts takes longer than fighters think
HRV helps manage all these demands to arrive at competition ready.
Fight Camp HRV Management
Early camp (8-12 weeks out): - Build base fitness with moderate HRV impact - Technical work at sustainable intensity - Watch trends—establish your camp baseline
Mid camp (4-8 weeks out): - Intensity increases, HRV will trend lower - Key is avoiding sustained suppression - Hard sparring should follow high HRV days
Late camp (2-4 weeks out): - Begin tapering volume - HRV should stabilize or rise - Reduce sparring to stay healthy
Fight week: - Minimal training - HRV often suppressed from weight cut - Focus on recovery and making weight
Weight Cuts and HRV
Weight cutting devastates HRV:
What happens: - Water manipulation = severe dehydration - Caloric restriction = metabolic stress - Sleep disruption from hunger/discomfort - Mental stress compounds physical stress
HRV during cut: - Expect 30-50%+ suppression - This is unavoidable with aggressive cuts - Resting heart rate will spike
Recovery after weigh-in: - Rehydration and refueling critical - HRV begins recovering immediately with proper rehydration - 24-48 hours is not enough for full HRV recovery - Fight performance may suffer from incomplete recovery
Strategic implications: - Smaller cuts = less HRV damage - Consider competing at a higher weight class - Use HRV to evaluate your weight-cut protocol
Sparring and HRV
Hard sparring is one of the most HRV-suppressing activities:
Before sparring: - Check HRV—high HRV days are for hard sparring - Low HRV = technical work or light flow - Fighting tired = more damage, less learning
After sparring: - Expect suppressed HRV for 24-72 hours - Head trauma may extend recovery - Don't stack hard sparring on consecutive days
Frequency guidelines: - 1-2 hard sparring sessions per week maximum - Technical/positional sparring is less demanding - Watch HRV to find your sustainable frequency
Between Fights Recovery
Post-fight recovery: - Complete rest for several days minimum - HRV will be severely suppressed - Return to training only as HRV recovers
Minimum recovery times (by HRV guidance): - 3-round amateur fight: 1-2 weeks - 5-round professional fight: 3-4+ weeks - Fights with significant damage: longer
Don't rush back: - Fighting on accumulated damage is dangerous - HRV reveals hidden CNS fatigue - Better to wait than to risk career
Active recovery: - Light movement is fine once HRV stabilizes - Swimming, cycling, walking - No sparring until HRV approaches baseline
Device Considerations
For fighters: - Wrist devices can be damaged in training - Oura Ring or Whoop offer durable, low-profile options - Morning readings with Polar H10 + app for most accuracy
During camp: - Consistent daily tracking is essential - Consider overnight tracking for complete picture - Log sparring sessions for correlation analysis
Around weight cuts: - HRV data becomes especially valuable - Track how your body responds to different cut protocols - Use data to inform future weight management
