Oura adds Cardio Effort and automatic VO2 Max to its smart rings

Oura is rolling out two cardiovascular tracking features, Cardio Effort and automatic VO2 Max, for Oura Ring Gen 3 and later models. Cardio Effort rates weekly cardiovascular strain against a personal baseline, while automatic VO2 Max activates after five GPS-enabled activities and is in beta via Oura Labs. Both require an active Oura membership.

• Cardio Effort rates weekly strain against a personal baseline from Light to Reaching
