Protocol
MAOD (Maximal Accumulated Oxygen Deficit), developed by Medbo et al. in 1988, is a laboratory test estimating total anaerobic capacity. It is considered one of the most reliable protocols for measuring true anaerobic capacity.
Phase 1 – Calibrated Submaximal Tests: The participant performs submaximal exercise at different intensity levels (4–8 stages) and steady-state VO₂ is measured at each stage. The VO₂-intensity relationship is determined by linear regression. This regression line is used to estimate theoretical oxygen demand at higher intensities.
Phase 2 – Maximal Exercise: The participant performs maximal exercise at ~115% VO₂max intensity for 2–3 minutes. Oxygen uptake (VO₂) is measured breath-by-breath throughout. Theoretical oxygen demand is calculated from the regression equation.
Calculation: MAOD = Theoretical O₂ demand − Measured O₂ uptake (L or ml/kg). High MAOD values indicate high anaerobic capacity. Typical values: male 50–80 ml/kg, female 40–70 ml/kg.
Post-Test: 10 minutes of active cool-down. Blood lactate measured at 3 and 5 minutes. MAOD value is correlated with the athlete’s anaerobic training adaptation.
Formula
MAOD (ml/kg) = Σ(theoretical_VO₂ - measured_VO₂) × time_intervals
Equipment Required
koşu bandı veya bisiklet ergometre, oksijen analizi sistemi (metabolik ölçer), kan laktat ölçer
Normative Values (Age: 18-35 (elit sporcular))
| Classification | Male | Female |
|---|---|---|
| Excellent | >80 ml/kg | >70 ml/kg |
| Good | 65-80 ml/kg | 55-70 ml/kg |
| Average | 50-65 ml/kg | 40-55 ml/kg |
| Below Average | 35-50 ml/kg | 25-40 ml/kg |
| Poor | <35 ml/kg | <25 ml/kg |
Practical Applications
The MAOD test is used in sports science research as a reference measurement of anaerobic capacity and in elite sprint athletes for monitoring training adaptation.
Limitations
It is a very long and cumbersome protocol that may take all day. Requires a metabolic cart. A clinical laboratory environment is essential.
