About Us

Estimate VO₂ Max Calculator exists to make aerobic-fitness insights practical and repeatable. We focus on clear inputs, instant feedback, and widely used field methods so you can track progress over time.

How it works

Choose a method and enter your numbers—results update live. We currently support:

• Resting heart rate: Uth-style estimate using an age-based max HR (208 − 0.7×age) and your resting HR.
• 1-mile walk (Rockport): Uses time, end-of-test heart rate, age, sex, and weight.
• 3-minute step (Queen’s College): Uses a 15-second pulse count (converted to bpm) with sex-specific equations.
• 1.5-mile run (Cooper): Uses your completion time.
• 2000 m row: Estimates average power from 500 m pace and adjusts per body mass and training level.

What we care about

• Clarity & accuracy. Equations are shown in plain language; units and conversions are explicit.
• Privacy-first. No accounts required; we aim to process inputs in your browser.
• Speed & accessibility. Clean UI, keyboard-friendly inputs, and readable typography across devices.

Safety

Field tests are estimates. The laboratory “mask” test is the gold standard. Consult a professional before strenuous testing, especially if you have cardiovascular symptoms or risk factors.

What’s next

• Shareable reports and simple CSV/PDF exports
• Contextual tips by method (e.g., pacing guidance, heart-rate measuring tips)
• Optional comparison logs to track training blocks
• Dark mode and improved mobile ergonomics
