Summer is approaching fast, and for us the first sign is always that our hills are no longer green and are now golden, which they will remain until the next rainy season in the fall. But the weather has been delightful for riding, not too hot until later in the afternoon when I am already finished. I do have to be a little careful about ride length because some pollen is in the air that gives me allergy headaches. Not too bad if I keep rides under 3 hours.
Last Tuesday my group did its “Taco Tuesday” ride for the 1st Tuesday of the month. We head south to San Martin, then turn east, and turn back north on the east side of the valley and up the Coyote Creek trail all the way to Metcalf Park, looping back over Malech road and back downtown for lunch.

On Saturday I took my upright out looking for some off-road riding.

Yesterday was a hard day, a brisk two hour 50 minute cruise with some on-bike strength training and intervals. Then I did some upper-body strength training in the garage.

On the other side is the start of the South San Jose neighborhoods.The neighborhood on the West side backs up onto the Santa Teresa foothills. You can ride along here for about 10 miles (16 km) north, with nice views of open space and Santa Teresa Park on the way.I climbed the steep hill on Bernal Rd that goes up both to the gates of the IBM research facility and Santa Teresa park. I worked in research here from 1984-1987. I heard it it is now closed down so I thought I’d go see the status. But the gates are still closed. IBM is probably keeping people out until they sell the building. If these gates were open you could drop down the West side on Harry Rd to the Almaden Valley.Part of Santa Teresa ParkBlasting back down the Bernal HillBernal-Gulnac-Joice Ranch is now a county parkThere is a dirt trail through the ranch that is a fun alternative to the road.
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...
