Maggie's Farm

We are a commune of inquiring, skeptical, politically centrist, capitalist, anglophile, traditionalist New England Yankee humans, humanoids, and animals with many interests beyond and above politics. Each of us has had a high-school education (or GED), but all had ADD so didn't pay attention very well, especially the dogs. Each one of us does "try my best to be just like I am," and none of us enjoys working for others, including for Maggie, from whom we receive neither a nickel nor a dime. Freedom from nags, cranks, government, do-gooders, control-freaks and idiots is all that we ask for.

Sarcopenia

From the Harvard Med. School Letter: Age and muscle loss



As the years pass, muscle mass in the body generally shrinks, and strength and power decline. The process begins earlier than you might think. Sarcopenia—defined as age-related muscle loss—can begin at around age 35 and occurs at a rate of 1-2 percent a year for the typical person. After age 60, it can accelerate to 3 percent  a year. The loss may be mild, moderate, or severe—or muscles can remain in the normal range...

Especially depressing given that I just turned 61, semi-retired a few years ago, and have let myself go. Guess I'll have to start working out.

It's never too late. Get up and get moving (and lifting).

The Barbell Prescription: Strength Training for Life After 40
Will literally change your life, if you are willing to put in the work.

All true, but endurance is a different system.

Which is why I posted here instead of in the Endurance Fitness thread.

Having said that, keep in mind that all that endurance work does little to nothing in staving off sarcopenia, while an intelligent weight training program, such as outlined in The Barbell Prescription, will give most people all the endurance they need in day to day living (especially with a HIIT session or two thrown in each week), while building both muscle mass and increasing bone density (among other benefits). Special events that require added endurance can be adapted to with a month or two of dedicated preparation. As the article linked to in the Endurance Fitness thread states: "Don’t underestimate how much strength plays a role in your endurance on a long hike."

Just came across this relevant and very infomative video from the author of The Barbell Prescription:

10 Myths That Keep You From Getting Fit After 50

Well worth 15 minutes of your time.

Protein seems to be a key element to keeping sarcopenia in check. Lots of useful clinical papers over at Science Direct.

Given we all know that aging sucks donkey dicks, I've never been able to understand why everyone has not been fully on-board with efforts such as Aubrey de Grey's SENS and the myriad efforts in cellular reprogramming to get rid of aging once and for all.
