GoKawiilOura Adds Cardio Effort and Automatic VO2 Max Tracking to Smart Ring
Oura announced two new fitness features for its smart ring: Cardio Effort, which rates weekly activity strain on a five-level scale compared to a user's baseline, and an automatically estimated VO2 Max metric. The VO2 Max feature, previously called Cardio Capacity, no longer requires a six-minute walking test and instead derives estimates passively from GPS-enabled workouts. VO2 Max will be available through Oura Labs for third-generation Oura Ring models and newer.
