Let’s bone up for winter. - #fitness #running #biking #exercise #nutrition #carfree #lifespan #fasting #longevity

The caveat of the cold adaptation training is to avoid actual hypothermia and frostbite. If you are training in the cold, you should look up the symptoms of these problems, so that you can avoid them. One solution for me is to workout near the train lines. If you need to bail, the nice warm train is not far. Bicyclers can include a blanket or additional warm clothes in the panniers. If you are running in the near athletic range, adding a light pack for cold weather is also probably a good idea. Essentially, if you have proven to yourself that you can run 10 miles every day, then adding a light pack is no big deal.
High athleticism creates diagnostic dilemmas, so in order to avoid unnecessary problems, going to the doctor should be a last resort. Try detraining before going to the doctor. One example of a diagnostic dilemma results from the fact that muscular types are sometimes misdiagnosed as obese. Another might be the presence of low levels of heart proteins, like cardiac troponin T (cTnT) in the blood, or small abberations in the ECG. Essentially, sick people are under alot of strain, and that strain sometimes looks mistakenly like the strain of healthful physical activity.
This study looks at the biomarkers of both skeletal and cardiac muscle damage.
All of us who are working out near the high athletic level are probably aware that it is not unusual to find muscle protein in the blood. We tell people that physical activity results in beneficial cardiovascular adaptations. Let's keep it consistent. There is almost no coronary disease in age under 40, but they get cTnT in the blood too. cTnT levels correlate with training level. If you are well-conditioned, don't worry about low-level cTnT in the blood.
More cold weather training notes
There must be a way to show that cTnT release predicts beneficial adaptation in the heart muscle. The problem is that we are so often studying disease instead of health and fitness. If you have a known heart condition, caveats obviously apply, but using low-level cTnT as a diagnostic tool would lead to too many dilemmas wrt. physical activity, IMHO. The problem would be compounded by similar dilemmas surrounding the BMI calculation. Many athletes sometimes keep mild symptoms to themselves, such as mild syncope or paresthesia, and the reason is obvious. Medical dilemmas lead to errors, and erring on the side of caution can harm people who are trying to do the right thing.
BTW, I can't wait to try my gel Cumulus running shoes. Wow! 6+ miles on the hills planned for Saturday, and lap time continues to improve. This is great progress. I only wish I could run much more! Time will tell. experience was indispensable. Many people would find the discomfort unbearable, but the pain is transient and mild, and the knees and quads recover quickly. The benefit is clear in the improved running capacity.
Regarding training advice\u2013
Here are the experiments. You can prove it to yourself.
Are athletic training improvements coupled to longevity improvements?
Athletic improvements remind a person about the reasons they are trying to live healthy. Exuberance is implicit in the process. A lap for me is 1.5 miles around the lake. I'm loving it. I should have started running laps around Druid Hill Park lake years ago. Running in the hills is a big thrill!
Using this training schedule, I've cut 4 minutes off my lap time. Improvement continues
When I get tired of the level path around the lake, hills and fields are just up the road. I love this place, Druid Hill Park. There are also dirt roads, shale stone trails, dirt trails, curbs, and circuit training stations, and lots of deer. The view is great, especially from the dam. You can see the whole city. All, to say nothing of Baltimore Zoo, which is right in the middle of the park. Light rail stops dot the path to the northwest ridges, the Jones Falls Trail. It is runner's paradise.
Biking v. running
Every time I hear the word "run" or "running" now, my ears perk up. It is so common in metaphor and parlance. When the body begins to acquire new capacity, it craves for more and more. I'm looking forward to my run today. I've been running off and on over the years, always to a false start. This time it is different. I'm making the best progress that I've ever made, thanks to fasting and a great training schedule. It is expected that within a month or two, I'll be attaining to speeds that I only ever dreamed of. Don't worry about the competition tho. My legs are rather short, and my feet have supination. ;-)
My first century ride, 112 miles
Liberty reservoir, PrettyBoy, etc, via bicycle -
After running in the hills the first time, I detrained for almost a week. The resulting recovery was a tremendous confidence builder. The detraining regimen is indispensable, but once you demonstrate recovery, get back to the training schedule. Distance is currently up to 6 miles. Calf strains are long gone,& I'm getting larger calf diameter. IMHO, if this trend continues, it will be another example of the beneficial effect of flavonoids and other polyphenols on muscle wear&tear.
Once I demonstrated that I could century ride on a bicycle reliably, running was the obvious next step for me. I hit the hills even harder this week, and I recovered more quickly as well. I'm really looking forward to pushing into the athletic range, in order to see if the benefits continue to accrue. The training schedule is friend. I would gladly run much too far without it. It occurs to me that failure in young athletes often results from failure adhere to a scientific training schedule. Another big pitfall is the temptation to set aside the diet that gave them success. Athletes who are successful in their youth probably learned exceptional nutrition skills from their mothers, and they should stick with that.
Assumption: perceived hunger level is a valid measure.
More Interval Fasting Notes
Birds, bats, and bicycles -
The model is that cold weather training promotes propagation of the mitochondria, but... In my view, the nutrition recommendations are more important. It's also useful to think of cold weather training in the same way as fasting: something that burns calories w/o any physical exertion. Fasting produces a larger caloric benefit, but cold weather training might also help. So, if you are minding the nutrition recomendations, here are the cold weather training recs....

Cold temperatures, strength, & aerobic capacity
BTW, this is one great motivation to run. - Be sure and scroll down to the phenethylamines link. It's an eye opener.
Anyone who thinks of adding mitochondrial capacity also needs to think of boosting RBC count. It appears that the flavonoids and other polyphenols improve mitochondrial count, but they also protect the mitochondria from damage. Cold weather training and fasting are ways to push those benefits farther, and they may help with the RBC count too. Sub-freezing weather is returning. I should be able to report about the added foot protection soon. I bought some winter boots for riding and hiking. I'm hoping for a large increase in the winter bicycling range, commensurate with the increase in RBC and mitochondrial counts.
Some organizations are loathe to give up their heavy weather secrets. Other agencies may withhold crucial information for reasons that are not in the benefit of others, or guide people into unfruitful paths. Over-competitive types are often all too happy to take advantage of our weaknesses. I recommend finding better associates. Ultimately, we take responsibility for our own training. Good luck with yours.
