New Fitness Metrics Added to Oura Smart Rings
They begin calculating after five GPS-tracked activities
Cardio Effort assesses the impact of an individual workout on the cardiovascular system and compiles a weekly summary. Load levels are categorized as "light," "moderate," "maintaining," "developing," or "achieving."
The metric considers both the intensity and duration of the session: a short, high-intensity workout may yield the same result as a longer, less intense one. The feature is available on Oura Ring Gen3 and newer models.
VO₂ max indicates how efficiently the heart, lungs, and muscles utilize oxygen during exercise. In the My Health Heart Hub, users can see their score in ml/kg/min, their fitness category—ranging from low to peak—the trend of the metric, and the date of the last update.
The company is also adding notifications about significant changes in VO₂ max or the stability of the score. Both features are designed to work together, showing workout intensity and accumulated effects over time.
