For daily = YES, but assessments, see below.
When using the BSXinsight for daily workouts to monitor muscle oxygen, the BSXinsight can be worn on any muscle group you're able to apply it to. However, the readings will vary depending on the engagement of the muscle and tissue characteristics.
For best results, you need consistent placement, light-blocking, and against the skin. We recommend you turn your calf sleeve inside out (reverse), put the BSXinsight in, like normal, and lay it flat where you want it, then wrap it, to hold in place.
Example, with the quad:
Above, the sleeve is reversed, with the BSXinsight properly placed.
Below, you want to find good placement, over muscle, and not lay it over any deep muscle separation.
Above, the BSXinsight is over the Vastus Lateralis, a great data point for sports like cycling.
Below, with the wrap over the sleeve and BSXinsight. You don't want to make it uncomfortably tight, just enough to hold it well against the skin and keep it from moving. You may see the outline of the BSXinsight on your quad when removing, but not so tight it's painful in any way:
For cyclists, you can then pull your shorts, or bibs over it. You should still be able to tap to "wake" the BSXinsight from this placement, once wrapped.
For assessment tests = It's not recommended to wear anywhere but the calf:
BSXinsight’s lactate threshold algorithms are highly tuned to the physiologic changes that occur in the gastrocnemius (calf muscle) during ramp testing. Because of variations that exist between the activation and usage of different muscle groups during exercise - such as the vastus lateralis (thigh muscle) - BSXinsight must be worn on the calf muscle during your endurance tests.
