Sunday I did a ride that started out urban in Morgan Hill, then through rural roads to the West and northward up to San Jose, then urban again in San Jose and back home, for a total of 48 miles. The high for the day was 84 degrees, and I was done earlier than that, so it was pleasant the whole way. This was another good test of my e-bike. I’ve mentioned in the past that I like to stand up to pedal a lot. I was against the wind heading north, and it worked great to stand up to pedal with a bit of assist.
In the parking lot of Morgan Hill’s Centennial Recreation center, which I passed on my way. The chainlink fences to the left enclose the outdoor training equipment, which dates back to Covid indoor restrictions. Some people liked working out al fresco, so they left some machines out there.This is the community park adjacent to the rec center. It has a pleasant dirt path around it I like to ride onWe are excited the new “Magical Bridges” part of the park is about to open, which has play areas for people of all ages and abilitiesDone with urban for now, heading out of town on Edmundson Ave.Ward’s Oak Glen farm on Oak Glen Ave, dating from 1894.Heading past Uvas reservoir on Uvas road, now heading north,Legend has it that the great Jockey Willie Shoemaker was part owner of this horse ranchUvas road has changed its name to McKean, heading past Calero reservoir with the Santa Cruz mountains in the distanceI left McKean to take the beautiful Calero Creek offroad pathTransitioning back to urban, this is the Almaden Valley neighborhood of San JoseBut right near the city streets, this Los Alamitos Creek Trail runs for several miles through a linear park
Unfortunately, my camera’s battery died so I couldn’t document the rest of the ride. Los Alamitos Creek trail comes out at Almaden lake city park, and from there I headed through the Santa Teresa neighborhood of San Jose. Then Santa Teresa boulevard took me back home. Tired but with a big smile.
https://ift.tt/aS2nC3F Fall in our area is not as spectacular as in other places but it’s nice that it lasts this long. 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...
