I recently enjoyed working with Gemini Deep Research to optimize my exercise program for optimal health. First, I asked about the best prescription for a 72-year-old (will be 73 tomorrow) with moderate paravalvular aortic leak who is also taking metoprolol (a beta-blocker that tends to slow the heart rate response to exercise). I got pretty conservative recommendations. This is because, in the absence of further data, the maximum heart rate is estimated using age-based formulas that tend to underestimate my actual maximum heart rate, and conservative assumptions are made about how much metoprolol will affect the maximum heart rate. Next I added the tidbit that my maximum heart rate while taking metoprolol was 160. That changed things and led to this this interesting report. The report made the following comment about the 160 beats per minute: “A critical data point in this case is the patient’s measured maximum heart rate of 160 beats per minute. In the context of a 72-year-old man taking metoprolol, this value is a significant physiological outlier that drives the entire exercise prescription strategy.”
The recommendations aren’t all that different from what I’ve already made, with the exception of the recommended intervals, which are said to be heart valve healthy. I did a series of lots of short sprints (15 seconds) followed by a good recovery. I thought this would be good for my valvular disease because it wouldn’t cause my heart rate to increase too much. That’s why I specifically asked if this was a good protocol, which leads to this this reportwhere the answer is emphatically no. Even if the heart rate remains low, blood pressure can rise excessively due to the intensity of the sprints. The recommended intervals are 1 minute with about 1 minute of recovery at a challenging, yet aerobic pace. I tried these and I like them better than the sprints anyway.
Another fun thing you can do with Gemini now is use its companion tool, Notebook LM, to create an infographic that summarizes a document. I’ve done this a few times and found them to be good quality. Doing this for the document with my recommended practice recipe resulted in the graphic above. Luckily, I didn’t experience any of the “red flag” symptoms.
