Heart rate reduced by half during the workout

Hi all

I could not find satisfactory answers to this problem, so I thought I'd post my own question. My apologies if someone has already replied.

In 'Other' training (weight lifting), I find measures watch my heartbeat correctly for about 10-15 minutes, then, for another 3-5 minutes, my heart rate is reduced by half, or worse.

After 3-5 minutes, the watch starts recording, which I assume to be the correct heart rate again.

I can't find a pattern, other that happens almost in the middle of my 30-minute workout. My heart rate is measured in the range of 140-170, then it comes down to 50-70 and then back to 140-170 until I finished.

It is a Sport of 42mm watch. I wear the sports Strip properly, no tattoos and I even shaved off part of my forearm to make sure.

Any suggestions? Should I get the replaced watch? Perform a factory reset? Make a small sacrifice to the gods Apple Watch?

Thank you!

Hi Richard

Several factors can influence the performance of the detector of heart rate, but it is expected that the sensor will give better results for workouts that involve rhythmic movements (e.g. running) rather irregular activity, such as lifting weights.

Make sure you wear your watch fits on top of your wrist (Apple suggests consider you the clamping Strip before starting a workout and it loosen again subsequently). When weight lifting, it can also help to wear your shows a little further to the top of your arm (away from your wrist in flexion).

It won't hurt (although it can't help, given the nature of the training) to also try restarting your iPhone and your watch:

-Switch off the whole appliance, then restart your iPhone first.

-To switch off your watch: press and hold the button side until you see the cursor off the power; slide it to turn off;

-To switch on: press and hold the side button until you see the Apple logo.

Also, check that your iPhone and the watch are updated with the latest version of the software:

- Update the iOS on your iPhone, iPad or iPod touch - Apple Support software

- Update the software on your Apple Watch - Apple Support

If you are still experiencing inconsistent results, consider a matching external monitor / Bluetooth chest strap for your watch.

    Hello

    Apple says that, even in ideal conditions, Apple Watch may not be able to save a reliable heart rate monitor each time reading for everyone.

    For best performance of the sensor of heart rate during the training, Apple suggests you consider your clamping beforehand watch band and he loosen again thereafter.

    The sensor is also likely to give better results for workouts that involve rhythmic (for example running) rather than the irregular movements (for example boxing). Other problems that can affect the performance of the sensor include the perfusion of the skin and wrist tattoos.

    If your workouts involve flexing your wrists (for example what weight lifting, for example), it can help to keep your watch a little higher on your arm, the joint in flexion.

    Hello

    When you save a workout using integrated workout app, your heart rate will be measured continuously throughout the workout. During training, you can also choose what primary metric is shown on your dial, with choices including heart rate. At the end of the workout, the results include the heart rate data. Training sessions are also recorded in the implementation of the activity on your iPhone.

    During the workout, to change the main metric indicated on the dial of the watch, slide on the side on this subject. Depending on your type of activity, the choice may include: time, active calories, total calories, heart rate, rhythm, speed and distance.

  • The way heart rate monitor works in watch

    I have been using shows since the first day he appeared in Spain. Latest operating system installed os shows 2.

    I usually run, leave, for example, 4-5 days a week. Sometimes in one race track, other running the streets.

    In November, I discovered something that makes that there is something wrong. The operation of the heart rate monitor. I found, specially everything by working in the rail bearing, series of facts and gestures and running at different speeds, that sometimes heart rate was 165 and, in the next step, same minute, he is 75, and then, following measures in the same minute, once again 165... I went to an apple store and gave them time to study, but they could not "recreate" the problem, so they have nothing did... Of course the problem occurs only when running, so I guess that none of the technicians used the watch to get out and run for a few kilometres.

    Most of the time the measures are ok, but last night, almost 9 km, running increasing pace, I found 6 times with incorrect measures.

    Attached you will find three examples of screenshot taken. In this case, the change in the average heart rate is not important, but in other cases I couldn't use the reference, the watch switches for 10 to 15 minutes of wrong measurement.

    The watch was properly placed around the wrist, so it wasn't the issue. And this has not happened before, with higher temperatures. Someone might say, s all about sweat, but there are more sweat in summer than in winter. Someone might say it is because of wearing long-sleeved shirts when running in winter, but this isn't the case, as I fold the sleeves to avoid it going between the watch and the skin.

    I don't mean the watch doesn't work properly, but, obviously, the results provided are not correct.

    Any help will be welcome.

    Kind regards

    Hello

    Even in ideal conditions, Apple Watch may not be able to save a reliable heart rate monitor each time reading for everyone.

    For best results, it is important for your watch to fit comfortably against the top of the wrist. To help with this, Apple suggests you consider your clamping watch band before workouts and it loosen again thereafter.

  • Assessment of heart rate

    is it possible to evaluate the heart rate?

    Thanks for the clarification on this Justin, I simply missed the obvious. I agree, if the product was led by VMware core customer that the importance and the necessity is worthwhile to develop such a product.  As a VMware customer, we have many requests for features that surround the suite of products that VMware offers.

    For us, VMware vCenter Server Heartbeat just makes no sense.  If your database is intact and well protected and with the ability to run vCenter as a virtual machine, you can have one instance of back upward and ready to use in less than an hour.  Yes, it will affect some products and features you mentioned but for a very short span of time, but it will affect production?  I guess it's a question that every company must answer.  For us, endure a clinical environment, we believe that the failure of vCenter for a short period of time would not affect care to patients or any other production system.

    Our company is a full VMware store and I believe in VMware and their products.  What works for one company may not work for another.

  • How to put in the front of the watch during swimming to see heart rate

    Received the Watch 2 day and taken for a swim practice in the pool (of course)

    happly to see enough faithfully has towers and gives average heart rate but only AFTER training

    I wanted to 4000 m (and I fact..) but from the exercise the watch when asked for the total calories to burn.

    QUESTION 1: how to set the distance (rather than calories)? At the start of the year?

    While the dial of the watch training appeared when out of the water and gave the number of laps, total distance, total time of exercise and calories burned.

    QUESTION 2: you can change the information presented during the swim to see heart rate? (Rather than the number of Calories predictable)?

    NOTE

    For swimming training, the watch is a bit disappointing, given that in the swimming training, you normally do a few repetitions as 10 x 100 start each 01:30 or 01:45. I normally use the watch of Garmin swimming to take the time (100 m start button and press again on arrival) of the clock, then briefly shows duration of the tour and afte 4 continuous seconds so you can see when you start again (e.g. to 01:45). I hope that there will be a third-party solution soon for Apple Watch 2, while I don't have to swim with two watches...
