While you’re getting fit, stay healthy. Crickles provides unique cardiac stress analysis calculated from the activities you record on your sports devices. This helps you to compare your training load to other athletes, build an appropriate amount of recovery into your exercise program and possibly spot and analyse anomalous heart rate readings at an early stage.
I was wondering whether your Sustainable Power / Heart Rate corresponded to you FTP or your LT1/VT1, and how you arrive at the value
Hi Cary. In essence, it’s an estimate of the heart rate that you can hold for an hour based upon (a) analysis of the heart rates that you’ve actually sustained recently over different time windows, and (b) empirical population analysis of relative heart rates over these time windows.
