Garmin to add Aerobic Swim Threshold & Blood Glucose Measurements to Connect
Eagle-eyed sleuth @JohnW has, once again, spied some interesting new additions to the Garmin Connect app, this time it’s linked to swimming zones and blood glucose both of which could have important ramifications for many of us.
Aerobic Swim Threshold
Garmin already allows you to determine your Critical Swim Speed (CSS) with a test and which it defines as
the theoretical fastest pace that a swimmer can maintain continuously without exhaustion…Your CSS is computed using your time for a 400 m or yard time trial, and your time for a 200 m or yard time trial.
However, the addition of a new measure, Swimming Aerobic Threshold, implies that Garmin might be looking at automatically adding HR zones for swimming based on a heart rate derived from your CSS efforts.
For several years I’ve used the ‘Secondary’ heart rate zone for swimming heart rate in addition to the two zones for running and cycling as, for me, the three are quite different. Maybe Garmin is formalising heart rate zones for triathletes and adding a dedicated zone for swimming? Maybe they plan to then add more analysis and insight to swimming efforts like, for example, combining training load together differently for all 3 sports. Perhaps not as the three are not really additive!
Or it could simply be CSS described differently as a threshold speed.
Either way, it’s a heads-up for something potentially interesting in the next few weeks.
Blood Glucose Measurements
The addition of blood glucose measurements is less of a surprise and their addition could be to support either consumer data or athlete data (or both).
In October last year, Garmin added CIQ (app-level) support for the Dexcom G6 Continuous Glucose Monitor (CGM) System and Supersapiens also has special integration with CIQ components and their blood glucose sensor (Abbot Libre).
It’s more likely that is a deepening of the medical/wellness side of things than of the athletic realm due to the Dexcom announcement.
It could even herald an eventual addition of a blood glucose ANT+ profile which would cover both wellness-medical and sports needs?
