Unexplained Heart rate

[Face Plant]

i hope that somebody could help me explain the heart rate anomoly ive been experiencing the last few days, i have just recovered from the flu so ive been on a forced rest for almost two weeks, so Friday i get back into things with a 5km run and my heart rate as i expected is rather high maxing out at about 192. Saterday i go for a 30km MTB ride and i couldnt get my heart rate over 120 Sunday i go for a 60km MTB ride and same thing, i just cant get my heart rate past 120. Last night i go for a 10 km run and check my heart rate after 6 kms and its 92 stayed like this most of the way and only maxed out at 121 at the end of the run.

 

the funny thing is i checked my pulse manually and it did seem pretty slow for the exertion levels, i felt as fatigued as i usually do with my HR up around 160 after a good run.

 

 

Is there a reason why my heart rate would be lower than usual or could it is it just my HR monitor playing up?

New batteries?

 

The flu will have an effect but not that much.

[TiBones]

for the HRM that is, not your heart!

[Christopher Brunsdon]

Sounds like the flu. Had the same problem a week ago and now I'm enjoying a smorgasbord of pills courtesy of my doc.

HRM has new batteries in it, from what Cbrunsdon is saying he experienced the same thing, could it be the bodies way of protecting itself from over exhustion when you not well?

Sounds like your HRM is at fault, however in your case I would play safe and assume the worst (still sick) until your 100% sure.

 

Perhaps supply some more info to help others help you , i.e.

1. Type of hrm and strap type (for example polar mesh type strap?)

2. When last did u replace the sensor / computer (watch?) batteries.

3. Normal 5K HR compared to the 192 you measured on a Fridays 5K.

4. Actual MHR or LTH HR prior to the flu.

i think cbrundson is right. i've also had that in the past when i thought i'd had a cold when it turned out i'd been a bit sicker than that.

1. Suunto T3c never had any issues with it before

2. new batteries in watch and strap

3. If i push on a 5k my HR goes up to about 171 max friday maxed out at 192 on the same route i usually run

4. Max HR is 189

well it all depends did you run and cycle at your normal pace? If you took it easy I could understand your HR being down a bit, but if you did it at normal pace and your HR monitor shows its that low it surely must be the HR monitor thats toast.

 

I am no doctor but I would expect someone who is still sick and doing excersize to experiance a spike in their HR not a drop? Or is my logic flawed as usual.

i ran at normal pace and i wasnt suprised when my HR was higher than normal on friday because as you say logic tells you that if you hvae been off for a while that your HR would increase, but then the next three days the opposite happends, what i dont understand is surely a HRM sensor is or going to work or not? would it actually be possible to get a "false" reading on a HRM?

I had the flu when I picked up my low heart rate. It now progressed to my lungs and was heading towards being bronchitis. My doc told me that if I don't fell better within 48 hours of getting the flu (when flu symptoms show), then it means it something worse.

 

So now I'm drugged up since Sunday hoping that I'm better tomorrow for the delivery of our next little Hubber.

Dont believe it, I've got 2 hrm (bike and run) and they both give unreliable bpm readings at the moment despite doing everything imaginable to cure it (besides buying a new strap).

 

Your HR may have been high on the friday due to the sickness and then the following days you could have been exhausted from the friday effort (sickness and training combined) and not able to get your HR up.

 

Do you monitor your resting HR, if its consistently higher than normal (5 bpm or more higher) then your probably still sick or not recovered properly.

my resting heart rate is slightly elevated but i atribute that to the two weeks of doing nothing, im doing a time trail tonight i will use my polar and see if the results are the same in terms of the lowered heart rate

Slightly elevated.....not a good sign.

Ummmmm TT might not be the wisest thing to do.

 

In my personal experience my resting HR stays the same or drops slightly (1 - 2 bpm) if I dont train for 2 weeks.

 

Maybe take the dog for a walk along the TT route.

Hi Guys, I will advice you NOT to train at all, unless you have seen a doctor and he gives you the OK. I had to have an heart operation (ablasion)to neutralize an over active heart muscle due to the fact that, according to the specialist, at some time I trained while I still had a flu virus and did not know it. Rather play it safe than sorry, 2 weeks of no training will not influence your fitness but it can influence your health. Take it from me I was only 29 and in top form. If you are sick your HR will go up. If you have taken some kind of medicine it can also have an effect on your HR and some MED takes some time to work out of your sistem as well.

I just went for my first long MTB ride, 92km,after the TransBaviaans. I have been riding on and off since the race but nothing serious, should mention we rode a good TB in our books, 13h30. I suffered a nasty wound due to a fall on the TB and this resulted in some rather bad infection, which resulted in 2 sets of "heavy" antibiotics in the last 3 weeks. This morning's ride turned our to be a real shocker, ave speed 23km/h, rolling hill ride. My heartrate spiked all over the place with the end result being an ave HR of 78%! I feel absolutely blown, as if I'm new to this sport and just got my backside kicked all over the place! Can this major fatigue and high HR be due to the antibiotics, infection still being around, or just plain having lost fitness? Please help with some advice as I have got a 3day race in 2 weeks!
