Altitude Training Testing in Santa Cruz

Planning altitude training camp or racing at elevation? VO₂ max testing in Santa Cruz before and after altitude exposure establishes baselines, measures red blood cell adaptations, and quantifies performance gains from altitude training for optimal preparation and evaluation.

Understanding the physiological benefits of training at elevation:

  • The Hypoxic Stimulus:
    • • Lower Oxygen Pressure: At elevation, less oxygen available per breath
    • • Body's Response: Stimulates EPO (erythropoietin) production in kidneys
    • • EPO Effect: Triggers bone marrow to produce more red blood cells
    • • Result: Increased hemoglobin, more oxygen-carrying capacity
    • • Sea-Level Benefit: Return to normal oxygen pressure with enhanced blood = performance gain
  • Altitude's Effect on Performance:
    • • At Altitude: VO₂ max declines ~1% per 300 ft above 5000 ft
    • • Example: At 8000 ft, VO₂ max reduced 10% (60 mL/kg/min → 54 mL/kg/min)
    • • After Return to Sea Level: VO₂ max rebounds to baseline + 2 to 5% improvement
    • • Performance Translation: 2 to 5% VO₂ max gain = 1 to 3% race time improvement
  • Elite Athlete Use:
    • • Virtually ALL world-class endurance athletes use altitude training
    • • Kenyan/Ethiopian dominance partly attributed to training at altitude (5000 to 8000 ft)
    • • Olympic athletes spend 4 to 12 weeks at altitude in pre-Olympic year
    • • Professional cycling teams: Altitude camps standard practice

Why testing before altitude exposure is critical:

  • Establish Sea-Level Baseline:
    • • Document current VO₂ max, VT1, VT2 at sea level
    • • Provides comparison point for post-altitude testing
    • • Allows quantification of altitude training effect
    • • Without baseline, can't prove altitude worked
  • Predict Altitude Response:
    • • High pre-altitude VO₂ max = larger absolute decline at altitude but good adaptation
    • • Baseline hemoglobin level influences EPO response potential
    • • Testing helps set realistic expectations for altitude camp performance
  • Set Altitude Training Zones:
    • • Know sea-level zones to adjust for altitude
    • • Rule of thumb: Reduce intensity 5 to 15% at altitude
    • • Example: Sea-level tempo 165 bpm might be 155 bpm at 7000 ft
  • Timing:
    • • Ideal: Test 1 to 2 weeks before altitude camp
    • • Allows recovery from test before travel
    • • Fresh, rested state provides accurate baseline

When and how to test after returning from altitude:

  • Optimal Testing Window:
    • • Days 3 to 21 After Return: Peak altitude effect window
    • • Day 3 to 7: Sleep disturbance resolving, ready to test
    • • Day 7 to 14: PEAK performance window (schedule key races here)
    • • Day 14 to 21: Still elevated but declining
    • • After Day 21: Effect diminishing, nearly gone by day 30
  • Expected Improvements:
    • • VO₂ Max: 2 to 5% increase typical (3 to 7% in responders)
    • • Hemoglobin: 1 to 2 g/dL increase (blood test confirms)
    • • Economy: Sometimes improves 1 to 2% (unclear mechanism)
    • • Lactate Threshold: Often shifts to higher % of VO₂ max
  • Responders vs. Non-Responders:
    • • ~70% of athletes respond well to altitude (significant EPO stimulation)
    • • ~30% are "non-responders" (minimal or no EPO increase)
    • • Genetic component to altitude responsiveness
    • • Post-altitude testing reveals which category you fall into
    • • Non-responders may need longer altitude exposure or higher elevation

Different approaches to altitude training and their effectiveness:

  • Live High, Train High:
    • • Method: Live AND train at altitude (e.g., Flagstaff, AZ at 7000 ft)
    • • Benefit: Maximum EPO stimulation
    • • Drawback: Training intensity limited by low oxygen (can't train as hard)
    • • Duration: 3 to 4 weeks minimum for adaptation
    • • Best For: Athletes preparing for high-altitude races
  • Live High, Train Low (Optimal):
    • • Method: Sleep at altitude (8000 to 10,000 ft), descend to train at low altitude
    • • Benefit: EPO stimulation while sleeping + ability to train hard at lower elevation
    • • Best of Both Worlds: Hematological adaptation + high training intensity
    • • Example: Park City, UT (sleep at 7000 ft, train at 4500 ft)
    • • Duration: 3 to 4 weeks ideal
    • • Research: Most effective protocol for sea-level performance
  • Live Low, Train High:
    • • Method: Live at sea level, train at altitude (opposite approach)
    • • Drawback: No EPO stimulation (need 12+ hours daily at altitude)
    • • Benefit: Peripheral adaptations (capillary density, mitochondrial efficiency)
    • • Verdict: Less effective than other methods for endurance
  • Altitude Tents/Hypoxic Chambers:
    • • Method: Sleep in tent that simulates altitude (8000 to 12,000 ft equivalent)
    • • Benefit: Can "live high, train low" from home
    • • Duration: 8 to 12 hours per night for 3 to 6 weeks
    • • Effectiveness: 60 to 80% as effective as real altitude
    • • Cost: $3000 to $8000 to purchase, or $200 to 400/month rental

Special considerations for racing at altitude:

  • Performance Decline at Altitude:
    • • 5000 ft: 2 to 3% slower than sea level
    • • 7000 ft: 6 to 8% slower
    • • 10,000 ft: 12 to 15% slower
    • • 14,000 ft: 20 to 25% slower (Pikes Peak Marathon altitude)
    • • Testing reveals YOUR baseline to calculate realistic race goals
  • Acclimatization Strategies:
    • • Option 1: Arrive 24 to 48 hours before race (before worst altitude sickness symptoms)
    • • Option 2: Arrive 2 to 3 weeks before race (full acclimatization)
    • • Worst Option: Arrive 3 to 7 days before (peak altitude sickness window)
  • Famous High-Altitude Races:
    • • Leadville 100 (CO): 10,000 to 12,600 ft, brutal altitude
    • • Pikes Peak Marathon (CO): Ascends to 14,115 ft summit
    • • Western States 100 (CA): 6000 to 8750 ft sections
    • • Boulder Peak Triathlon (CO): 5400 ft
    • • Pre-testing helps set realistic goals for these events

Using Santa Cruz (sea level) for altitude training benefits:

  • Perfect Sea-Level Testing Location:
    • • Santa Cruz at sea level = ideal baseline and post-altitude testing
    • • Nearby altitude training: Lake Tahoe (6200 ft, 3 hour drive), Mammoth Lakes (7800 ft, 5 hour drive)
    • • Test in Santa Cruz → Train at Tahoe 3 to 4 weeks → Retest in Santa Cruz = quantify altitude effect
  • California Altitude Training Destinations:
    • • Mammoth Lakes: 7800 ft, excellent facilities
    • • Lake Tahoe: 6200 ft, iconic training location
    • • Big Bear Lake: 6750 ft, popular with SoCal athletes
    • • Flagstaff, AZ: 7000 ft, many pros train here (6 hour drive)

Why some athletes benefit more from altitude than others:

  • Genetic Factors:
    • • EPO gene variants influence altitude response
    • • Some athletes produce 200% more EPO at altitude than others
    • • Baseline hemoglobin level (genetic + training history)
    • • Iron absorption efficiency (affects RBC production)
  • Testing Reveals Your Response:
    • • Pre vs. post-altitude VO₂ max change quantifies YOUR response
    • • If large gain (5%+): You're a responder, continue altitude training
    • • If minimal gain (1%): Non-responder, may not justify altitude camps
    • • Allows informed decision about future altitude training investment
  • Optimizing Response:
    • • Iron Supplementation: Ensure adequate iron stores before altitude (test ferritin)
    • • Duration: Minimum 3 weeks at altitude, 4 weeks better
    • • Elevation: 7000 to 9000 ft optimal (higher not necessarily better)
    • • Sleep Quality: Maximize hours spent at altitude (12+ hours sleeping/resting)

Typical altitude training camp progression and testing schedule:

  • Week -2: Pre-altitude VO₂ max test at sea level (Santa Cruz)
  • Week 0: Arrive at altitude (e.g., Mammoth Lakes), immediate performance decline
  • Week 1: Acclimatization symptoms (headache, poor sleep, high HR), easy training only
  • Week 2: Feeling better, EPO increasing, can train harder
  • Week 3 to 4: Full acclimatization, training at near-normal intensity, RBC production peaking
  • Week 5: Return to sea level, immediate super-compensation (feel amazing!)
  • Week 5 + 7 days: Post-altitude VO₂ max test (Santa Cruz) to measure gains
  • Week 6: PEAK performance window-schedule key races here
  • Week 8+: Altitude effect fading, back to baseline by week 10

  • Costs:
    • • Lodging: $1500 to $3000 for 3 to 4 week camp
    • • Travel: $200 to $800
    • • Lost work/income: Variable
