Vo2 max walk activity

Hi.

My vo2 max is back after almost a month. I didnt know why was gone and i dont know how came back. It only matters that works now. But works only with running, not anymore with walkiing activity.

Does anyone get vo2 max with walking activity or walking activity does not estimate it anymore?

    reliable HR values only in walk activity (strange i know)

    Not strange at all. Optical heart rate is affected by movement. When you are walking you impart less movement to the watch. A completely expected outcome once the limitations of optical heart rate from a wrist watch are understood...and accepted.

    look like you didtn read al my posts. I use walk activity for run, hike, trail run, walk... becuase i get in in walk activity good HR values no matter waht sport i do. If i am hiking and i use hike activity i have Hr values all over the place, sometimes i have 100 HR but in reality i have close to max HR, but if i use wlak activity and i am going hiking i have good HR values. Do you understand now?

    I got the first ever VO2 max after walking today because it is exactly one month to the day since I last ran. There are other (cycling, MTB and walking) activities in the last 30 days but this is the first non-running activity to generate a VO2 max reading.

    The Fenix 6 must default to walking activities after one month. After saving the walk activity it displayed VO2 max and recovery time as it used to after a run.

    I've been doing a bit more side by side testing of 6X WHR (green) vs a strap (red) for walking and the results are mixed. Here are results from today - an easy stroll, hands empty and arms relaxed.

    For the first 28 minutes the agreement is mostly there or thereabouts, with a few odd deviations, but from 28 minutes onwards the 6X just seems to lose all interest in measuring anything and just makes a half-hearted effort to produce numbers. There is no explanation. I did nothing to change the fit of the watch or the way I walked.

    I've also tried some tests where I've been recording the "walk" while driving to and from the park. Results when driving are great. Results when entering/exiting the car and attending to the dog are less reliable (as might be expected). Results for actual walking are, in my experience, all a bit too random to be trusted.

    Yesterday results were pretty good throughout, including driving....

    The previous day, pretty good, but a lot of excessive peaks during the walk and quite a bit of nonsense early in the return drive home.

    Two days before that, just for walking without the driving bits, shockingly bad.

    Bottom line, which some of us already know - if you want reliable data then use a strap. WHR might work, sometimes, but equally it might not. Sure you can glance at WHR and see a plausible figure, but equally there are figures which are completely out of whack with exertion at that moment. 

    Walking might be OK for VO2max, with a strap, but I wouldn't put my trust in WHR numbers for anything more critical than mooching about. Errors when walking the dog can be tolerated, I guess, but not for performance metrics.
