VO2max Equation:
| From: | To: |
The VO2max cycling equation estimates maximal oxygen consumption from 20-minute cycling average power and body weight. It provides a practical method to assess cardiovascular fitness and endurance performance in cyclists.
The calculator uses the VO2max equation:
Where:
Explanation: The equation correlates power output relative to body weight with oxygen consumption capacity, providing an estimate of aerobic fitness.
Details: VO2max is a key indicator of cardiovascular fitness and endurance capacity. It helps athletes monitor training progress, set performance goals, and optimize training intensity.
Tips: Enter average power from a 20-minute maximal effort cycling test in watts, and body weight in kilograms. Both values must be positive numbers.
Q1: How accurate is this estimation method?
A: This provides a reasonable estimation for trained cyclists, but laboratory testing with gas analysis remains the gold standard for precise VO2max measurement.
Q2: What are typical VO2max values for cyclists?
A: Recreational cyclists: 40-50 ml/kg/min, trained cyclists: 50-60 ml/kg/min, elite cyclists: 60-80+ ml/kg/min. Values vary by age, gender, and training status.
Q3: How should the 20-minute test be conducted?
A: Perform after proper warm-up, on a consistent course or trainer, with maximal sustainable effort for the entire 20-minute duration.
Q4: Does this equation work for all cyclists?
A: Best accuracy for experienced cyclists. Novices may have different efficiency, and the equation may overestimate their actual VO2max.
Q5: Can I use this for training prescription?
A: While useful for fitness assessment, training should be based on power zones, heart rate, and perceived exertion rather than VO2max estimates alone.
