Cooper Test or Non-Exercise mode · ACSM + India-calibrated norms

🏃 Cooper Test Mode: Run as far as possible in exactly 12 minutes on a flat 400m track. Record total distance in km. Ensure near-maximal effort with adequate warm-up.
Sex & Age * VO₂max norms are sex and age-stratified. Females show 10–15% lower absolute VO₂max at matched training load due to haemoglobin and body fat differences.
Sex
Height & Weight * BMI is used in the non-exercise equation. Weight is needed for calorie and nutrition calculations. South Asian BMI cutoffs apply (overweight ≥23 kg/m²).
📌 If entered, replaces BMI in equation. % body fat-based models have lower bias than BMI-only models (Rao et al., 2023).
Cooper 12-Minute Run Distance * Total distance covered in exactly 12 minutes on a 400m flat track. Near-maximal effort required. 1 lap = 400m = 0.4 km.
📌 Enter in km. Example: 7 laps = 2.80 km
📌 Auto-converts to km
Sport Category * Different sports have distinct distance–VO₂max relationships. Sport-specific equations derived from Indian athlete cohorts (swimmers, volleyball, track, cricket).
Training Age (years of structured training) Used as a covariate in the Cooper multivariate model. Experienced athletes achieve higher VO₂max at similar distances due to better pacing economy.
💥 Exercise Calorie Calculator
Exercise Type * MET values from Ainsworth 2011 Compendium. Calorie = MET × weight(kg) × duration(hr). VO₂max-adjusted for higher accuracy when available.
Session Duration * Post-workout nutrition requirements scale with duration. Sessions >60 min require additional carbohydrate replenishment (AIS/IOC 2023).

⚕️ VO₂max estimates from field tests and non-exercise equations are population-level approximations. Individual error (SEE) is typically 3–5 ml·kg⁻¹·min⁻¹. For elite selection, clinical diagnosis, or precise training prescription, cardiopulmonary exercise testing (CPET) with gas analysis is the gold standard. Cooper test results are valid only with near-maximal effort on a standardised track. Non-exercise estimates are suitable for screening and group comparisons.
