![]() ![]() I can’t count the number of times where it seemed my HR was directly correlated to how fast I was descending – despite the fact that I was working less. This is often caused when the wind funnels down the front of your bike jersey and either induces additional static buildup as noted before, or introduces false readings through vibrations. As a side note, some of the Polar straps actually have an antistatic component built into them that helps to alleviate this problem to some degree.ģ) Wind on the bike: One fairly common issue especially in the spring/fall when you’re wearing simple bike jerseys but the wind and lukewarm air temperature keeps you relatively dry, is that when you go down hills fast, or simply the wind hits the right way, you’ll get incorrect readings. You can try rubbing the strap or your shirt with an antistatic agent – the ANT+ folks recommend simply a bounce dryer sheet, as that can help in some cases. In almost all cases, simply applying moisture will immediately resolve this issue. This is most common when your skin and air are both rather dry, and very little moisture is present. We’ll talk about moisture additives in the next section.Ģ) Synthetic shirts (quick dry/tech shirts): While all of us love not being suffocated in cotton shirts, an unfortunate side effect is that those synthetic shirts (normally called quick dry or ‘tech’ shirts) produce additional static electricity buildup that messes with the readings. Simply introducing any moisture at all will usually remedy the situation – at least until you begin sweating enough to let that do its job. Which, means you often get incorrect readings. This in turns lowers your conductivity ability from a readings perspective. This means that you’re less likely to have moist skin (due to even just skin perspiration), and even less likely to be generating any sweat right from the start of the workout. So assuming that you’ve got it all correctly ‘installed’, let’s look at what typically causes the spike in HR (if it’s over 200bpm, it’s likely not legit unless you’re a seven year old).ġ) No moisture, dry air: During the winter months the air is often fairly cold, and fairly dry. Also, the ANT+ folks note that from a placement standpoint “the strap is worn on the ribcage, below the pectoral muscles or breasts”.Īll good and you’re still having issues? Onto the next section we go… It should not be worn over your clothing. Now, one last important item to note is that it goes UNDER your shirt against your skin. Also note that you cannot mix Polar HR straps/units with Garmin HR straps/units.) However, the T31 coded straps from Polar will work underwater with their respective Polar units – just ensure it’s noted as T31 coded. (Minor side note, as you may know, none of the Garmin ANT+ HR straps will read HR underwater more than an inch or two away from the watch, as I showed in my 310XT review while underwater. Garmin Premium HR Strap (also called soft HR strap):Īnd for all you Polar folk, their coded HR strap: I’ve circled these in the pictures below: Which side is the electrode side? Well, the side with the little bands, not the shiny side. On the Garmin ANT+ straps, you’ll want to ensure the Garmin logo is right-side up, and the electrode side of the strap is against your bare skin. As the most important thing to do is ensure you’re wearing it correctly. Let’s first start with how to put the strap on. ![]() And…I can probably even help ya fix it too! ![]() Well, let me help ya out and explain why and what it’s doing. Sometimes you might even reach into the mid-200’s.Īfter you finish your activity and get back to your computer, you’ll probably see something like this – a major HR spike, followed by more normal HR activity:įrustrated, you poke at your HR monitor some, perhaps browse the Internets a bit – but in general forget about it, until it happens again. But before you know it your HR is blistering through the 150’s, 160’s, and right on through the 200bpm glass ceiling. It starts off fairly innocently with a gentle rise in heart rate (HR). For those who train with heart rate monitors often, you probably know all too well know the tell-tale sign that your little device is lying to you about your heart rate. ![]()
