Heart Rate Monitors, Pedometers, Bike Computers

Sat Sep 29, 2012 11:13 am

Is there a heart rate monitor out there that's accurate? I've been hitting the treadmill in my apartment building's fitness center and it's got one of those dinky little "palm-reading" hrm's, tells me my RHR is 95 bpm when I know it's actually 71. I'm trying to burn off the last of that belly fat and apparently that means getting my heart rate up to 135 for x number of minutes. The treadmill's hrm isn't going to do it. Any recommendations?

Also, assuming I ever do get meself a bicycle, does anyone recommend a certain bike/handlebar computer? I'm going to want speed and odometer info (not sure what other features are even available  &nbsp  and most important it has to be backlit for night-time operations.

One more thing - pedomter recommendations, anyone?

Get anyone with electrodes on a chest band. Those are as accurate as an ECG.

They do not need to be expensive, though. I've used a Sigma Sport PC 3 for a long time, later I've upgraded to the Sigma Sport PC 9 to get additional statistics like calories burned, average heart rate, time spent in each heart rate zone...

There are some with an encoded ECG signal. The plus is that they don't interfere with anybody else's heart rate meter, the downside is that if your heart rate watch is broken, you also need to buy a new chest band.

The only problem I've encountered is that they don't work well in electromagnetic fields. The PC 9 does not work near railway lines, and the PC 3 always showed a heart rate of 82 near railway lines (which is five times the frequency of the railway power frequency, 16.667 Hz).

If the electrodes do not pick up a signal, make them wet with saliva. They won't work on dry skin.  

Have fun!

P.S.:

I get that heart rate on a brisk walk. So I run in the 155 to 165 range, and I can keep that up for 90 minutes straight.

Relatively, you burn more fat while running at a lower heart rate, but absolutely, it is higher if you waste more energy by running at a higher heart rate. Just do not eat or drink any carbohydrates after your run. The going rate is that you have replenished your body carbohydrate store in 6-12 hours if you ingest carbohydrates, or in 12 to 24 hours if you eat nothing, and let the body convert fat mass into carbohydrates.

Long-distance runners actually train fat-to-carbohydrate-conversion by not eating any carbohydrates in the 2-3 days before the run, but on the eve of the run, they feast on pasta.

I always liked my wireless Cateye bike computer. I don't know what model number they are up to now.

You might be better off with a GPS instead of a computer then - a Garmin or something similar. All basic computers I've seen aren't backlit. You can get ones that allow you to link an HRM and cadence (how fast you're pedalling, basically) sensor to it - giving you a readout once you download it of route, speed, cadence, heart rate and what your HR was at a certain point etc.

Slightly off topic but worth adding in:

Don't get a $100 "walmart special" bike - it won't last. It's built from cheese and will last around 50 miles (if that). It's worth spending extra (even on a 2nd hand one) that will last you a lot longer.

Well, how long has it been true - that they are accurate? I used one of those at a private gym in 1994 and it had the same problem as the treadmill one - said >90 bpm when the truth was 70ish,

The formula a personal trainer gave me is (220 - age) * 0.75. Also she said fat-burning is best accomplished by interval training - I might get there, it's just I'm spending these first few weeks just getting acclimated to a nightly treadmill routine. Breaking the ice.

I've never in my life ever set foot in a Walmart, nor do I plan to. I was looking at the $199 Schwinn ones they sell at Mills Fleet Farm. I've actually had a couple of $99 bikes in my life, acquired at Sears and then at Target; I had no problems with them. I'm not a serious bicyclist; just enjoy a casual weekend cruise-around, and maybe if I could get a milk-crate thingy installed I could use it for light grocery shopping.

I bought my Sigma PC 3 in... 2010. As I said, I only had problems when running near power lines.

Okay.   Ice. Mmm!

As somebody with a resting pulse rate of 55, but a rate of 130-140 on a brisk walk, I didn't want to use such a formula. In my case I would end up with 142. Instead, I sometimes test my maximum pulse by gradually running faster, faster, faster until I drop dead. Then I have a look at the maximum pulse rate (mine is in the 200-210 range). Consistently, the fastest speed I can run for longer times is 70 to 80% of the max pulse rate.

Well, i just meant in general - you'd get a lot more bike for your money if you paid $200 for a used one in good condition for example than a brand new one.

If you wanted to do some shopping a simple rack on the back with a pair of panniers would be fine. The rack I have is rated for 25kg (55lbs) which is by far enough, then you could strap stuff to the plate on the rack with some bungees.

220 - age is the maximum heart rate for a cardiac stress test. Some doctors will stress to that, or 90% of it (aka target heart rate) but that's in a controlled environment with a defib nearby. For me, the formula you give would equal 127 which is not that much, the bike and treadmill at my gym yell HIGH HEART RATE at around 150. I'm not fit by any stretch of the imagination, sitting here now watching TV and typing this my HR is around 85. (Mind you there are hot chicks on VH1   )
