Content overview: “Oura Ring Adds VO2 Max and Cardio Fitness Tracking to Smart Rings”. Oura has rolled out new health metrics for its smart rings, focusing on cardiovascular fitness. The update introduces estimated VO2 Max, a key indicator of aerobic endurance, along with other cardio-related stats. This brings the Oura Ring closer to dedicated fitness trackers, offering users a more complete picture of their heart health without needing a separate device.
The feature likely uses heart rate and activity data already collected by the ring, combined with user demographics, to estimate VO2 Max. For consumers, this means the Oura Ring can now help track improvements in cardio fitness over time, a metric previously reserved for chest straps or high-end sports watches. It matters because VO2 Max is strongly linked to long-term health and longevity, making it valuable for everyday users, not just athletes.
