VO2 Max API
Aerobic-capacity (VO2 max) estimation as an API, computed locally and deterministically. The cooper endpoint estimates VO2 max from the Cooper 12-minute run test, VO2max = (distance − 504.9)/44.73, from the distance covered in twelve minutes. The resting endpoint uses the resting heart-rate (Uth-Sørensen) method, VO2max = 15.3 × (HRmax/HRrest), with the maximum heart rate taken directly or as 220 − age — a lower resting pulse signals better fitness. The rockport endpoint applies the Rockport one-mile walk test, a multiple-regression formula on age, weight, sex, walk time and the heart rate at the finish, the most accessible sub-maximal field test. Each result comes with a broad fitness rating from poor to superior and the value in mL/kg/min. Everything is computed locally and deterministically, so it is instant and private. Ideal for fitness, running and endurance-training app developers, coaching and assessment tools, sports-science and wellness dashboards. Pure local computation — no key, no third-party service, instant. Live, nothing stored. Estimates only, not medical advice. 3 endpoints. This is aerobic-capacity estimation; for heart-rate zones use a heart-rate API and for basal metabolism use a BMR API.
