Nobel Prize in Medicine for Autophagy Research 

From P.D. Mangan:

“Autophagy is the regulated process in which cells break down their own constituents, such as proteins and organelles like mitochondria, into their more basic parts such as amino acids, and recycle them for later use, either burning them for fuel or using them to make new structures. The cell replaces the old parts that it’s destroyed and replaces them with brand new ones.

In this way, autophagy provides for renewal.

Autophagy is critically important in aging and disease. One of the most characteristic aspects of aging is a decline in the levels of autophagy. Since aging by definition is an increase in the susceptibility to disease, it can be seen how important autophagy is to all diseases.

Autophagy relates to virtually all chronic diseases in one way or another, and even some non-chronic diseases, like infection. It’s important in cancer, cardiovascular disease, and brain disorders such as Alzheimer’s and Parkinson’s.Autophagy declines in aging. A salient characteristic of youthful organisms is a robust response to stimuli of autophagy, most notably the absence of food, or fasting.When old, the level of autophagy is only 20% or less in some mammals than that seen in youthful members of the same species. Increasing it to youthful levels is perhaps the most important thing within our control to slow the aging process.”

Brain Benefits of Exercise Diminish After Short Rest, Says Gretchen Reynolds 

Steve Parker MD

Admittedly, Gretchen may not have written the headline to her article at Carlos Slim’s blog. The headline is wrong. The gist is that blood flow to the brain diminishes in older competitive runners if they stop exercising for 10 days. Tests of cognitive function showed no deterioration.

Click the link below to read Gretchen’s article, which is brief. A snippet:

“Before you skip another workout, you might think about your brain. A provocative new study finds that some of the benefits of exercise for brain health may evaporate if we take to the couch and stop being active, even just for a week or so.

I have frequently written about how physical activity, especially endurance exercise like running, aids our brains and minds. Studies with animals and people show that working out can lead to the creation of new neurons, blood vessels and synapses and greater overall volume in areas of the brain related to memory and higher-level thinking.

Presumably as a result, people and animals that exercise tend to have sturdier memories and cognitive skills than their sedentary counterparts.

Exercise prompts these changes in large part by increasing blood flow to the brain, many exercise scientists believe. Blood carries fuel and oxygen to brain cells, along with other substances that help to jump-start desirable biochemical processes there, so more blood circulating in the brain is generally a good thing.”

I believe regular physical activity does help preserve brain function over time. But there’s more involved than blood flow.

PS: I bet your brain blood flow increases, compared to watching Dancing With the Stars on TV, if you read one of my books.

Endocrine-Disrupting Chemicals: An Area of Growing Concern 

The worrisome chemicals, mostly or entirely man-made, are in the environment, water, food or food packaging. From MNT:

“The Endocrine Society’s Second Scientific Statement on Endocrine-Disrupting Chemicals (EDC-2) was developed “to bridge [the] gap between basic, translational, clinical, and public health knowledge, EDCs,” according to its lead author.

“About 10 years ago, the Endocrine Society began working with a group of scientists and physicians to consider the evidence that EDCs are a significant concern for human health,” Andrea C. Gore, PhD, of the University of Texas Austin, told MedPage Today. “In 2009, I led a group of authors in writing a review paper, which led to the Society’s first Scientific Statement. Five years later, the evidence linking EDCs to chronic endocrine diseases involving reproductive, thyroid, cardiovascular, type 2 diabetes mellitus, obesity, and even hormone-sensitive cancers, had mounted. We wrote EDC-2 to review this evidence based on animal models and epidemiology, and the resulting paper allows us to draw much stronger conclusions about concerns about EDC exposures.”

Speaking of Hiking: Canada’s 15,000-Mile Trail Is Almost Done 

“Do you like to hike? If your answer is yes, consider booking a trip to Canada for 2017. But you might want to pack a few extra pairs of hiking boots—as Eillie Anzilotti reports for CityLab, Canada’s newest trail will be nearly 15,000 miles long.

No, that’s not a typo. When it’s finished next year, the Trans Canada Trail will clock in at 14,864 miles long, nearly 13,000 miles of which are connected. As Anzilotti reports, the trail will open to everyone from cyclists to skiiers, horseback riders and hikers in 2017 and will be the world’s longest recreational trail.”

My Merrell boots (model unknown)

Click through (link below) for the details. I enjoy hiking and will eventually have to replace my current boots, which I paid about $120 for. So this post is for future reference. I hope it helps you, too. It’s easy to buy boots that don’t fit.

Intro:

“Ever wonder how to buy boots with a good fit? Whether you’re buying boots for hiking, on the job, or working around the home, it is important to know how to find the best fit.

Here are five simple ways to know that your boots fit right… A proper fit is when the boot is snug enough to prevent your feet from moving inside (which is how blisters are born) but not so tight as to constrict circulation.”

PD Mangan Makes the Case for Compound Lifts

And he’s right. RTWT:

“Many people seem to have the wrong idea about weight training.

Whether you are in the gym for overall conditioning, for building muscle to prevent aging, or to become an actual bodybuilder, the process should involve working all of the skeletal muscles.

It appears to me — and this is a guess — that many people look at muscular men and see big arms to the exclusion of anything else. They then proceed to do isolation exercises, like biceps curls and triceps pull downs, to the exclusion of most other things.If your goal is health, work on all of your muscles.

If your goal is size and strength, work on all of your muscles.”

QOTD: Mussolini Defines Fascism

“The foundation of Fascism is the conception of the State, its character, its duty, and its aim. Fascism conceives of the State as an absolute, in comparison with which all individuals or groups are relative, only to be conceived of in their relation to the State. The conception of the Liberal State is not that of a directing force, guiding the play and development, both material and spiritual, of a collective body, but merely a force limited to the function of recording results: on the other hand, the Fascist State is itself conscious and has itself a will and a personality — thus it may be called the “ethic” State…. ..The Fascist State organizes the nation, but leaves a sufficient margin of liberty to the individual; the latter is deprived of all useless and possibly harmful freedom, but retains what is essential; the deciding power in this question cannot be the individual, but the State alone … ”

Benito Mussolini, 1932

P.D. Mangan: Brief Workouts Produce Significant Strength Gains 

"One more rep then I'm outa here!"

“One more rep then I’m outa here!”

You don’t need to spend lots of time a the gym to gain the benefits. Depending on your goals, 30 minutes a week may be enough.

From P.D. Mangan:

“Bodybuilders, gyms, and most publications devoted to it advocate that you train often, as frequently as five times a week. Is this necessary, and is this optimal?

The fitness industry has an obvious conflict of interest here: it wants you to use their products as much as possible in order for them to earn more money. If you are told to workout more often, you will be more likely to renew your gym membership, buy more supplements and equipment and magazines, and just generally to order your life so it revolves around weight lifting and fitness.

Others, more scientifically oriented, claim that you don’t need to train as often to maximize muscle gains, not that you need to do more than one set of each exercise. In the very informative book Body by Science, Doug McGuff, M.D. advocates once weekly workouts, a far cry from the three to five a week often advocated elsewhere. McGuff bases his recommendation on a number of things, most importantly the speed at which muscle recovers and grows from an intense workout, which is much slower than most people think.”

Bodybuilders Sell Steroids to Fund Their Own Use and Maintain Social Status, Report Finds

No evidence of anabolic steroids here. Primarily estrogen.

No evidence of anabolic steroids here. Primarily estrogen.

This study was based in Europe, so may not apply to the U.S.

Anyway…

“Many bodybuilders illegally sell steroids to help fund their own use of performance and image enhancing drugs and maintain their social status in the weightlifting community, a new academic study has found. Researchers at Birmingham City University analysed more than 60 criminal cases and interviewed dozens of people involved in the purchase and sale of performance enhancers in the Netherlands and Belgium, to identify the different types of people drawn to selling the drugs.

The report found that sellers often broke the law to help fund their own use of steroids and that most viewed the substances no differently to high street supplements such as protein powders, energy bars or sports drinks.”
