Why do I have a high HR with low intensity exercise?

Answered on July 02, 2013

I am trying to figure out why my heart rate skyrockets even when doing a light jog. This has been happening more over the last year, where a jog at best in the past would get my heart rate up to the 140 bpm now it quickly goes to 165 or higher in a matter of minutes. My resting heart rate is only around 52 to 58 bpm and my resting blood pressure is 125/80.

Any thoughts on what could cause this to happen? Thyroid or mineral imbalance maybe?

To see that you're getting in shape and not going backwards due to possible overtraining, you could do the MAF Test every 15 days or so. I've found it really helpful over time. http://philmaffetone.com/maftest.cfm

Putting on some weight does affect your VO2max, the ligther you're the more performance can expect from endurance cardio exercise. Even like this, 25 BPM seems a little bit too much. You don't describe how you're feeling, just the difference, so there's a lot of data missing that may be interesting. Are you exercising too much? That may be a cause. Have you upped a lot your carb intake? Carb loading for me can skyrocket my morning HR, not that much with training but a little bit. You checked you thyroid but maybe could benefit from checking cortisol and anaemia as suggested.

I mean 5 or 6 lbs. I've been heavier than this in the past by 10 or more lbs and was not an issue. Maybe I should clarify the question, aside from weight gain, or being out of shape, what could cause someones heart rate to skyrocket on a very light jog in a matter of minutes?

When you say "a few lbs" do you mean 3 or 4, or do you mean 20?

Would gaining a few lbs really cause that great of an increase in heart rate? HIIT was required to get to 165 or higher, now a very light jog causes HR this high....regardless of temp, time of day ect, does that not seem like an excessive change? Or really high for a very very light Jog??

Are you comparing workouts at the same time of day, same temperature (i.e. not winter vs summer), same level of hydration?

Gaining weight will definitely increase heart rate too. It could be that.

I wouldn't consider myself out of shape, not optimal shape, but not worse than prior to HR skyrocketing. FT3, FT4 and TSH all suggest optimal thyroid.

That's correct, I wouldn't say i'm out of shape just that my heart rate has progressively been getting worse over the past year. I used to have to do HIIT to get my HR to the same level that my warm up jog now takes it (165bpm). I have been having put on a few pounds but this isn't due to a lack of healthy eating or exercise. Thyroid blood work (TSH, T3, T4) all suggest optimal levels.

In response to the suggestions that the OP might just be out of shape, I'm assuming that fombi doesn't find "light" jogging to be considerably harder than before, it's just that the HR is higher- am I right?

because you are not in good shape.

I would at least rule out electrolyte imbalance. Eat more salt, bone or beef broth and take a Magnesium chelate supplement. Bananas or avocados for potassium. More seafood.

Could be thyroid, but could also be plain old anemia. Worth checking out with a doctor.

I agree with foreveryoung. Are you in worse shape than you used to be? When I am not running much, my heart rate goes up easily but when I'm in shape, it takes a lot more to get it up much at all.

Maybe just start pushing yourself a little further or faster and see if you can get your heart used to the harder activity.

If your resting heart rate is low but even light exercise shoots it up drastically, you're probably hypothyroid and out of shape.

This in contrast to someone who is fit with a low resting heart rate, and where it takes comparatively much greater work to bring the heart rate up.
