Another valuable health feature has been added to iPhone and Apple Watch with iOS 14.3 and watchOS 7.2 – Cardio Fitness. The measurement is based on your VO2 max that Apple Watch may estimate when recording certain workouts. Follow along to see how to use Cardio Fitness on iPhone and Apple Watch, including why it’s important, how to set it up, and how to measure / view Cardio Fitness levels.
Here’s how Apple describes Cardio Fitness levels:
With iOS 14.3 and watchOS 7.2, Apple Watch users can view their cardio fitness level in the Health app on iPhone and receive a notification on Apple Watch if it is in the low range. Groundbreaking technology released in watchOS 7 allows Apple Watch to easily measure low cardiovascular condition, and today cardio fitness notifications allow users to be more active for dramatic long-term health benefits. term.
Cardiorespiratory capacity, measured by VO2 max, is the maximum amount of oxygen the body can use during exercise, and it can be increased through physical activity. Apple Watch already estimates average and higher levels of VO2 max during vigorous walking, running or hiking, which many runners and other athletes monitor to improve performance.
Essentially, Cardio Fitness is a metric that gives an indication of overall health and can predict long term health as well. While there is a correlation between low levels of cardio fitness and future health problems, you have the power to increase your levels with constant aerobic exercise.
