Oura announced two new health-tracking capabilities for its smart ring lineup. Cardio Effort is a physiological load metric that measures cardiovascular strain during workouts by factoring in workout intensity and duration over a week. The second feature enables passive VO2 Max measurement, removing the requirement for users to perform a six-minute walking test. These additions expand Oura's existing suite of health metrics including sleep quality and cardiovascular tracking.

  • Cardio Effort tracks physiological cardiovascular load during workouts
