FR945 BUG - Nonsensical Recovery Advisor - Swimming

JanLouisDT
over 2 years ago

My FR945 is a great watch and I love it. I have customized all the HR zones and power zones for the different sports, and it seems to be in the right ballpark when it comes to training load status, and recovery advisor in most cases.

Except for swimming: It is quite normal for me to get recovery time suggestions of 72+ hours for an easy swim where I almost never leave HR zone 2. This messes up my entire recovery advisor data field, because just by some easy swimming a couple of times a week, I am constantly in a state of "overtraining".

Here is an example of this morning's swim:

Duration: 41m29 | Average HR: High zone 2 | Training load: 105 | Primary benefit: base (3.0)

Time in Zones: z1: 3% | z2: 44% | z3: 30% | z4 and z5: zero

Recovery time: 4 days

Is anyone else experiencing this issue?

    My recovery time on my 945 is fine and makes sense. Have you set the critical swim speed in the user profile? I am not sure if the recovery time considers your swim speed vs your critical speed for recovery, but its the only thing I can think of to check.

    That's a good suggestion, I'll do an actual css test and set it correctly Ok hand tone1

    Did that work for you?

    I seem to have an inverse problem. Just added swimming to my routine. I get annoyingly low load points for my effort.

    A run for half the time of a swim,  with similar hear rate distrib will get double the number of load points. (so a 4x difference).

    I can swim till I cramp (Ie,  no small load) and the watch will still call me a slacker... I've never customized zones etc explicitly, but have ran and biked with the fr945 a lot.

    Any tip for me? Thanks!

    I see calorie numbers somewhat similar to running but a much lower exercise load when swimming — though I’m more surprised by the high calorie numbers than the low exercise load.  I think it is difficult to maintain anything like a running heart rate while swimming  — though maybe I’m just a poor swimmer.

    I would argue that for the same HR distribution, a high impact activity like running will have a higher training stress on your body than a lower impact activity like swimming.

    I can confirm that setting the CSS correctly did not work. Did my usual 40min easy Z2/Z3 swim and got a 46 hour recovery suggestion. Exercise load 121, average HR 79% of max. A 40min run at this intensity results in about half the load. Intensity minutes for swimming is a mess, I got 1 moderate minute and 1 vigorous minute for a total of 3 intensity minutes, what a joke

    My calorie numbers are slightly lower for swimming than for running, but the intensity of my swimming is lower than my running.

    This has been my experience and observation

    Although looking at the stats in my original post, it seems to be a lot better now, even though it's still not what I would expect
