alphaHRV (update)

@Inigo_Tolosa Is it possible to change battery field with cadence ? I think it more usefull.

@Marchewka alphaHRV is not a general purpose metrics viewer. I am displying only metrics that have a direct impact on a1 and respiration (external load: power or speed/pace)
HRM battery level is shown to help you detecting potential wrong results, because when battery is low, measuring accuracy of the HRM can be affected.
Anyway, alphaHRV supports any layout in your device, so that you can combine it with any other data field to create a screen that matches your necessities.

What Iā€™ve been doing (to avoid having to restart or whatever) is change from AlphaHRV to a different ConnectIQ dataview then back again.

Quite a kludge but how does one get Garmin to fix annoying bugsā€¦ :-/

I have a problem upgrading the new version. I have Edge 530 and on my smartphone on IQ connect the version always displays ā€˜In queueā€™. It will not update my version. Any ideas???

Change to a profile on your Edge where the AlphaHRV is not active. Just create a new std profile without any IQ field.
Then reboot your Edge and sync with mobile phone.
Some updates donĀ“t install when the field is active.

As @MedTechCD says, sometimes updates are not applied. You can use the procedure explained by him or update+synchronize+restart. This one usually works for me.

Ok, it worked. Update for alphaHRV installed. Does it matter what graph you select in the options? alpha vs RRa1?

So now ready to do another protocal as explained above in the topic and then plot the data so to get a new estimation of LT1ā€¦

Selected plot only sets what you want to display. All the parameters are calculated normally whatever plot you select. In fact, you can always change to a different plot on the go. If you are using a touch screen device, just tap on the plot legend

My fault. I donā€™t have the Rra1 data yet. Tomorrow my planned step test with updated AlphaHrv app ;-). Will update thĆ© topic tomorrow with my resultsā€¦

Im unable to get alphaHRV working. I have Fenix 7x, latest beta FW, updated alphaHRV. Latest Polar H10 firmware, set to dual BT and ANT+. Fenix HR sensor set to BT, alphaHRV set to ANT+. alphaHRV finds ANT HRM ID properly, but when I start activity, percentage bar gets stuck at maximum 75 percent. If I try to reselect alphaHRV IQ data screen, it starts all over, but stuck again. Any idea?

How do artifacts look like? Does alphaHRV display correct HR even when collecting percentage gets stuck?

After hard reset of H10 - battery out and short connect of battery terminals, it worksā€¦
Checked on Fenix 7x and EDGE 1040.
Go figure.

Iā€™ve managed to put my polar H10 sensor through washing machine and has stopped working so using an old Garmin hrm-dual. Iā€™m not getting alpha hrv to pick up this which Iā€™m assuming is a limitation if the hrm-dual?

This has been a very useful app so may have to invest in another H10 but thought Iā€™d check first

Garmin dual should work. Maybe you need to upgrade firmware?
I think it is done through your Garmin device but only if the strap is connected in ANT+ as a standard HR sensor.

Thanks - Iā€™ve got it working via ANT+ (in the Connect IQ alpha HRV data field) with the sensor then paired to the watch by BLE in the main garmin watch menu. Will test it out tomorrow to see how it works in terms of artifacts etc - used to get very low artifacts with H10

Best setup I found is Garmin Dual strap with Polar H10 sensor on it.
The Garmin strap feels more comfy for me and appears more reliable.
And yes, ANT+ connection to the IQ field, BLE as std HR to the Edge.

As a newb, I have AlphaHRV as my main screen on my traininer and it has been really amazing to set HRLT1. After months of indoor zone 2 rides that sometimes bleed into zone 3 it is really cool to see RR/a1 inflection around 135-140 bpm and visually see there is some physiological difference between 135 (top end of Z2 in 5 zone model) and 140 (bottom end of Z3). Over 135 I also consistently see a ā€œdipā€ in RR/a1 as if that transition from Z2/Z3 is very efficient (a drop in RR and/or rise in alpha1) before the linear move up at 140. I was able to see that just from the consistent volume I did and not to any specific tests.

Thank you @Inigo_Tolosa for creating and sharing such an amazing app.

What is the best way to also use RR/a1 to determine HRLT2?

Most of my intense rides are outdoor mtb rides without power data and I donā€™t do them enough or in a structured enough way to get meaningful/consistent data from RR/a1. For my next ā€œseasonā€ w/ periodization in the fall Iā€™de like to build into my training plan some recurring indoor HRLT2 testing protocol (maybe once a week, or every other week) to ā€œteaseā€ out what my HRLT2 is from a RR/a1 perspective. Most of the protocols appear more like FTP ramp tests, but I would suspect that lots of times doing over/unders around FTP should be enough (maybe even better?) to confirm HRLT2 without going full FTP ramp mode. I donā€™t want to do FTP ramp tests on a weekly basis :slight_smile: and I think that the FTP tests I have done (and the HRLT2 detection on various platforms) probably overestimate my true physiological LT2 (184bpm !?!?!, as a 46 yo, I donā€™t think so, but 180+ bpm detection is typical when doing 45 min all out race pace efforts, and 167-172 is typical on hard group rides, but not all out). From a pure RPE perspective (ā€œI could do this in a steady state for awhileā€) I suspect my HRLT2 is more around 160. I also suspect that my high detected HRLT2 is because Iā€™m good at making myself suffer and pushing myself to the extreme.

If I knew what that HR was, then I think it would 1) help me confirm, physiologically, what power to set for training over/unders and 2) help me pace better on longer mtb rides which would effectively be like doing over/unders given the uneven terrain.

Thanks!

Rather than do a Ramp Test which is an approximation at best and can be a fairly inaccurate one have a read of this: The FTP Test: Physiology and New Protocols

Someone have ideia if can work on future updates for Fenix6 , or forerunner 245music?

The app is too big to be built for these devices
