Altitude Training Effect Calculator Formula
Understand the math behind the altitude training effect calculator. Each variable explained with a worked example.
Formulas Used
VO2max at Altitude
altitude_vo2max = sea_level_vo2max * (1 - vo2max_reduction_pct / 100)Acute Performance Loss
performance_loss_pct = vo2max_reduction_pctExpected Post-Camp Benefit
expected_benefit_pct = camp_duration_weeks * 0.5Variables
| Variable | Description | Default |
|---|---|---|
altitude_m | Training Altitude(m) | 2400 |
sea_level_vo2max | Sea-Level VO2max(mL/kg/min) | 55 |
camp_duration_weeks | Camp Duration(weeks) | 3 |
vo2max_reduction_pct | Derived value= (altitude_m - 1500) * 0.0074 | calculated |
How It Works
Altitude Training Effects
Training at altitude (1,800-2,500 m) stimulates red blood cell production, potentially improving sea-level endurance performance.
VO2max Reduction at Altitude
% Reduction = (Altitude - 1500) x 0.0074
This approximation starts reducing VO2max above 1,500 m. At 2,400 m, expect about a 6-7% reduction. After returning to sea level, athletes typically see a 1-3% performance improvement lasting 2-4 weeks.
Expected Benefit
Post-Camp Benefit = Camp Duration (weeks) x ~0.5%
A 3-week camp at optimal altitude may yield 1-2% improvement.
Worked Example
An athlete with 55 mL/kg/min VO2max trains at 2,400 m for 3 weeks.
- 01VO2max reduction = (2400 - 1500) x 0.0074 = 6.66%
- 02Altitude VO2max = 55 x (1 - 0.0666) = 51.3 mL/kg/min
- 03Expected post-camp benefit = 3 x 0.5 = 1.5%
