Yesterday I did about 30 minutes of upper body workout, then joined my group as we rode to the foothills by Gilroy, southeast of Morgan Hill. We saw the goats and pigs at a small farm along Crews road. Then we rode up to Bridal Path Road to visit Aladdin the camel and his buddy, an Ethiopian Bull with big horns. We finished back in Morgan Hill for lunch. It was a nice brisk ride, we formed a paceline on long stretches with headwinds. I was happy to be able to keep up well with my non-assist upright, even on some steeper sections in the foothills. This is a great group and fun to ride with.

Aladdin, looking majestic but a little disappointed we’ve run out of carrots.

Some trees have lost their leaves by now, but other species, such as maples, are peaking. Yesterday I enjoyed a long ride up into the hills West of town. I rode through Paradise valley then past Chesbro reservoir, and returned to town via Willow Springs road, enjoying the glorious sunshine. Long rides at an easy pace, like this one, feel like they are good for my leaky heart valve, or at least are relaxing. I won’t give them up unless my cardiologist convinces me too, but I’m pretty sure he’ll approve.

https://ift.tt/wxOr4u3 My last strength workout went really well, I was able to go pretty hard without pushing my heart rate excessively. But afterwards it occurred to me that monitoring heart rate might not be enough. Strength training can cause a temporary spike in blood pressure which is probably not a good idea. I figured there must be a lot of research on this, because there are a lot of older people with cardiac limitations besides mine which is relatively rare (including heart-attack survivors, angina sufferers, and those with valve regurgitation). And they are still encouraged to do strength training to prevent sarcopenia. So I asked Gemini deep research about it and it produced this fascinating report . It points out that a resistance training session, properly performed, is beneficial to the heart because while it temporarily raises blood pressure, there is “a phenomenon known as post-exercise hypotension, where blood pressure remains below pre-exercise resting levels for se...
https://ift.tt/V59Jb1v A recent article in Neuroscience News covers a Stanford study [1] on cell secretions during exercise. These were previously known about but it was not possible to isolate them from the blood for study. The Stanford group came up with a novel way to dive deeper into the blood to isolate these molecules, called exerkines. The study was on mice and had some surprising results. One was the high number of exerkines produced during exercise. “This means that the effects of physical activity are very widespread across many tissues and organ systems,” one of the co-authors of the study said. “We’re only just starting to understand that complexity.” A second surprise was some unexpected healthy changes (anti-obesity, anti-diabetic, and exercise performance-enhancing) related to liver cells. This new approach is promising and I’m interested in seeing it repeated in humans. References Wei, W, et al, “Organism-wide, cell-type-specific secretome mapping of exercise tr...
