Metoprolol effect on exercise – bionicoldguy

Since the aortic valve was replaced in 2017, I have been on the beta -blocked mitoprolol. This is mostly to prevent potential arrhythmias, but also helps in controlling blood pressure. It seems that it works well and I have no noticeable side effects, unlike the heart rate does not seem to rise significantly during exercise. Wednesday showed its effects more dramatic. I finished a prescription bottle and on Wednesday morning I couldn’t find the replacement bottle. I usually consider the first thing in the morning before any activity. I decided to go on my journey anyway and search for it later. On Wednesday, it was scheduled to be a more difficult journey, and the long rhythm rhythm, followed by a separation and training session. I wore a chest belt to monitor the heart rate, which I know is accurate.

During the rhythmic part of the ride, I noticed that the heart rate was higher than 10 beats than I expected, as it approached 120 on average, despite the fact that the level of the perceived of the effort was similar to modern horse riding, and it passed the “Test Test” until it was not very deceptive. (So ​​people are not concerned that I am talking to myself walking on the road, using the alphabet’s alternative to reciting). Then during the timeline session, I noticed that I reached heart rates in the 150s, which I had not seen for a while. I found the replacement bottle after I finished the ride and took my dose. But this incident planted the seed of curiosity. I noticed that the bottle says that you take it “in the morning”, and not necessarily the first thing in the morning. By searching the web, I couldn’t find any reason that makes it good to exercise early in the morning and then take metoprolol. It seems a good idea to take it at the same time every day. So I will start taking it constantly later in the morning after exercise.

I was also curious about what is known about its effect on sports performance. Mentioned In this video By a famous cardiologist in the UK, beta blockers such as metoprolol weakens the performance by maintaining the heart rate during exercise. This looks logical. If I am in chronology and my legs screaming for oxygen, it seems that I may not be able to go with the same difficulty if the heart rate remains in the 130s instead of 150s.

I have recently been searching for topics like this on Google Gemini. If you click “Deep Search” in the “Ask Gemini” box, instead of answering your question only, you will search in a group of related sites on the Internet, then go to the results and submit a report. This is the fun use of artificial intelligence. So I did this, and I wrote in “the effect of metoprolol on athletic performance.” Come with This detailed reportAnd from which I learned a lot. Metoprolol appears to affect durability, such as a slight decrease in maximum oxygen consumption (VO2MAX). Taking metoprolol is necessary to prevent potential arrhythmia. But for anyone who takes this or other beta blockers only to prevent high blood pressure, there are alternative blood pressure medications, which have been discussed in the report, which has a much lower effect on performance.

There is also a good discussion about beta blockers and exercise This site. The bottom line is that it is completely safe to exercise strongly while eating metoprolol, and it does not seem to matter if you take it before or after, as long as you take at the same time every day.

I am not really worried about some slight weakness in performance. Since I have been dealing with drugs since 2017, and I was often interested in competing “against myself”, all of my last performance that I would compare with it was equal.

I am a mechanical engineer born in 1953, PhD, Stanford, 1980. I was active in the CAE mechanical field decades ago. I also have a lifelong interest in external and fitness activities. Both hips have been replaced and the heart valve is replaced by a genetic condition. This blog chronicles my adventures in staying active despite these bumps on the way.
