Swimming OHR finally here!

For me the whr is useless because is  reading around 30 higher than tri. But did any one else noticed that every time now after this update the stroke length is 0,01m, total strokes and SWOLF also messed up.

Just so happy for you guys. After 3-4years of waiting for it(while schosche rhythm'ed for OWS HR, with excellent results, while also seeing current HR during swims- important for me as I charge different seas at very different temperatures, and distances), now 1month + in my HR Swim strap swimcation. Which I totally agree with Garmin, that "for accurate HR reading"... I should have probably listened long time ago. Oh well...

Had 935 and was too big,light and plasticky for my needs.

IA So I would probably wait out the F6. Totally love the F5 for now. Small enough to fit under a weight lifting glove strap, so that makes it a go to all around banger. Great ROI from a 350$+59$ setup(BNIB off Ebay).

Cheers, IA'll,

Please confirm that wrist-based heart rate for swimming accumulates intensity minutes. This is a limitation of HRM-Swim and HRM-Tri.

Yes, wrist heart rate accumulates intensity minutes

Hmmmmm...

Phil, Also, you were right all this time. I was wrong.(about the strap).

Cheers,

I've not been swimming much recently so had little chance to try WHR in the swim, however I did today. It's fair to say that if I could get consistency reliable results like today then I would be very happy - pool swim 945. The heart rate is probably very close to what I'd expect for the lack of effort I was putting in. I have no faults there. There is definitely progress being made, but one swallow does not name summer. Consider this result form my wife's 945 pool swim yesterday. Way too high for her. She doesn't get her heart rate that high even when doing hard efforts running or cycling.

But certainly, there's a promising result from my swim today that hopefully will not be a one-off.

A general question... do you find that generally HR recorded during swimming (regardless of how, let’s assume it is 100% correct) corresponds to the actual effort experienced (RPE)?

in other words, does HR during swims make sense as a metric for training load? I was always under the impression that swimming load goes by different rules than running/biking due to the difference in dynamics between water and air?

Heart rate during swimming makes sense as a metric for training load as long as it is correct. I know that sounds obvious, but it still amazes me how several posters to this forum seem to think that any data is good data irrespective of how accurate that data is. If I get a result from the OHR when swimming that puts my heart rate at over 150 bpm average (and I have had that) when realistically it's 120, and consequently returns completely wrong training effect, how is that of any use? I don't care how closely the recorded data tracks my intervals. It's of absolutely no use if those numbers are way too high. Although the pattern looks good :-)

RPE is something that I think for many people needs 'recalibrating' when swimming. For most swimmers, heart rate can be expected to be 20 bpm or more lower than running primarily because all you are doing when swimming is propelling your body through the water, not carrying it as when running. It's not an issue of a difference in dynamics between water and air so much as the water is supporting all your body; all you have to do is to propel it through the water.  Swimming is effectively weightless propulsion, although you have to drag your body mass through the water, it is entirely supported by the water.

For less experienced swimmers, I suspect RPE would depend on how confident and competent you are in the water. For a lot of people, it's the breathing that is the limiter when swimming and that can increase the feeling of breathlessness that is then reflected in a higher RPE for a lower heart rate. I am a slow swimmer, but very confident, breathing easily to both sides so rarely get breathless and can swim easily. For me I am very confident that the swim HR I saw on Saturday was a pretty good representation of how I felt for the amount of effort I put in. In that case I'd say it works for training load. But I have other swims where the result has not been as good.

In short, when the data is good, training effect from WHR in the water is good and makes sense as a metric for training load. Which is pretty obvious really, Well I think it is obvious. Garmin are doing some great work with the WHR, especially with these newer watches. The time when I will ditch the strap is getting closer. I'm just not sure we're quite there yet.
