Propanolol And Heart Rate

[ck1]

I regularly use a rowing machine and always do 5K which takes me about 20 minutes, my heart rate gets up to a peak of 190. I've been using propanolol for the last 5 weeks and now find that my HR doesn't get anywhere higher than about 130 even though I'm doing exactly the same thing. Is this a usual side effect of propanolol and is the exercise being less useful from a health perspective if my HR isn't getting very high?

[Prudie]

That is one of the main effects of propranolol so don't worry. Whether it makes exercise less useful is an interesting point that I don't know the answer to.

[Sqad]

I agree with Prudie.
Propanolol is a beta blocker and hence slows the heart rate down which manifests itself in exercise as well as rest.
No, the exercise is still useful.

Because you will now have a lower baseline as well the relative increase should be similar, more or less efficient.... not sure but probably safer with the propranalol than without.

God I am amazed you can do anything after taking propranolol

I mean god it certainly works - after one tab you can show b blockade for seven days

athletes dont usually take propranolol and I would expect their peak exercise level to go down. I dont think data exists on how valuable it is in training ....
is used by sportsmen such as shooters and bowmen
