The effect of Metoprolol on Exercise – Bionicoldguy

Ever since my aortic valve change in 2017, I was on beta-blocker metoprolol. This is the most to prevent possible cardiac arrhythmia, but it also helps to control my blood pressure. It seems to work well and I have no noticeable side effects, except for my heart rate it does not seem to increase as high during the exercise. Wednesday showed its effects more dramatically. I had finished my bottle with a recipe and on Wednesday morning I couldn’t find a replacement bottle. I usually take it first in the morning before any activity. I decided to continue later and look for it later. Wednesday was scheduled to be more difficult to ride, a long fast pace trip followed by an interval session and training by bicycle. I wore my chest strap to monitor a heart rate, which I know is accurate.

During the pace of the ride, I noticed that my heart rate was more than 10 strokes higher than I expected, approaching an average of 120, despite the fact that my perceived load level was similar to the last such rides and I passed the « talk test », so my breathing was not too working. (So ​​people do not worry about talking to myself, getting down the road, I use the alternative alternative to the alphabet). Then, during the interval session, I noticed that I reached heart rate in the 150s that I had not seen in a while. I found the replacement bottle after I finished the ride and took my dose with a delay. But this incident planted seeds of curiosity. I noticed that the bottle was saying to take it « in the morning », not necessarily the first thing in the morning. Exploring the web, I could not find a reason why it was not good to exercise early in the morning and then take Metoprolol. It seems to be a good idea to take it at the same time every day. So I’ll start taking it in the morning after my workout.

I was also curious about what was known about its effect on athletic indicators. Mentioned In this video From a well-known cardiologist in the UK, beta-blockers like metapolol, disrupt effectiveness, maintaining a heart rate lower during exercise. This seems logical. If I do an interval and my legs scream for oxygen, it seems that I may not be able to go so hard if my heart rate remains in the 130s instead of the 150.

Recently, I’ve been researching such topics in Google twins. If you click Deep Research in the Ask Gemini field, instead of just answering your question, it will look for a bunch of relevant websites on the Internet, then review the results and make a report. This is a fun use of AI. So I did this and introduced « Metoprolol influence on athletic indicators ». He went out with This detailed reportFrom which I learned a lot. Metoprolol seems to affect the efficiency of endurance, such as a slight reduction in maximum oxygen consumption (VO2MAX). My receiving metoprolol is necessary to prevent possible arrhythmia. But for anyone who accepts this or other beta-blocker solely to prevent high blood pressure, there are alternative blood pressure drugs discussed in the report that have a much lower effect on efficiency.

There is also a good discussion about beta-blockers and exercises This websiteS The bottom line is that it is completely safe to exercise vigorously while taking Metoprolol and it seems no matter if you take it before or after, as long as you take it at the same time with each day.

I’m not really worried about a slight impairment. And since I have been on drugs since 2017, and I am most interested in the « Against myself » competition, all my recent performances that I would compare were equally affected.
