Oura Smart Rings Gain New Cardiovascular Health Features
The new update introduces Cardio Effort and passive VO2 Max tracking to help users monitor their cardiovascular health.

New Capabilities for Fitness Enthusiasts
Oura, a leader in the wearable technology market, has significantly expanded the capabilities of its smart rings. The company announced that users will soon gain access to new cardiovascular health monitoring tools, designed to provide deeper insights into training processes and overall physical condition.
The headline feature of this update is Cardio Effort. This system serves as a physiological load metric, specifically engineered to assess the stress placed on the cardiovascular system during exercise. The ring analyses both the intensity and duration of workouts to provide users with a comprehensive picture of how much strain their body has endured throughout the week.
Automated VO2 Max Measurement
Another significant addition is the passive measurement of VO2 Max, or maximum oxygen consumption. Previously, users were required to perform a specific six-minute walking test to determine this metric, which proved inconvenient for daily use. With this new update, the Oura ring will calculate this data automatically, without the need for any additional activity.
This change greatly simplifies data collection. The passive measurement method allows the ring to continuously monitor a user's physical fitness and provide updates on the dynamics of their cardiovascular system's capabilities. This information is particularly valuable for athletes and those focused on improving their general health.
What These Changes Mean for Users
Oura rings have long been recognised for their sleep quality analysis and recovery monitoring. By adding these new features, the company is positioning its devices more as fitness trackers, serving as an indispensable assistant during both rest and active training.
For users interested in fitness technology, these updates allow for more precise workout planning and the avoidance of overexertion. Through Cardio Effort, it is now possible to optimise exercise intensity, while passive VO2 Max tracking allows users to monitor the endurance growth of their cardiovascular system. This update represents another step toward technology helping us better manage our health.
