The ECG app uses sensors to record the electrical signals that control how your heart beats. It analyzes that recording to detect signs of an irregular heart rhythm called atrial fibrillation (AFib).
This feature measures your ability to sustain prolonged efforts and combines training data from all your athletic pursuits to help you understand how training impacts your overall endurance. This dynamic measurement uses your VO2 max, short-term/long-term training loads and other factors to gauge your fitness progress beyond just VO2 max.
The resilient athletic design features a 1.4” scratch-resistant sapphire solar charged display, responsive touchscreen, traditional buttons and 51 mm fiber-reinforced polymer case with a titanium bezel and rear cover. The watch is tested to U.S. military standards for thermal, shock and water resistance.
Your health and training data should be easy to interpret and provide actionable insight. Begin each day with a customizable morning report, and see a daily summary of health and wellness information. Use the training readiness feature — which looks at a variety of different health metrics to help you maximize your training efficiency and recovery3 — to prevent burnout.
