Quickstart

from client import PersonalAgentCardiorespiratoryVo2MaxVelocity

agent = PersonalAgentCardiorespiratoryVo2MaxVelocity()
res = agent.estimate_vo2max_from_heart_rate_ratio(resting_hr_bpm=54.0, max_hr_bpm=185.0, age=42)
print(f"VO2max: {res['estimated_vo2max_ml_kg_min']} mL/kg/min | Fitness Age: {res['biological_cardiorespiratory_age']} yrs")
