A few studies caught my attention this week, not for being all that surprising or groundbreaking or even new, but because they jibed with something I’ve been mulling over: physical activity in old age.
Studies: the first and second. I grouped these together because they largely deal with the same thing. The first, actually a review of a couple dozen separate studies, discusses how basic physical capability seems to predict mortality later in life, while the second focuses entirely on the predictive ability of a person’s walking speed. This is redundant to anyone who’s ever felt a euphoric post-workout rush or the satisfaction of completing a physically taxing task, but judging from the number of people who make endless loops in the parking lot to score that sweet spot by the door and avoid empty staircases in favor of crowded escalators, we are in the minority. Things like grip strength, the time it takes to rise from a chair, the ability to balance on one leg, and walking speed were strong determinants of mortality. The death rate was 1.67 times higher in folks with weak grips, 2 times higher in those who were slowest to rise from the chair, and 2.87 times greater in people who walked at the slowest pace. Most of the studies reviewed were of older subjects, but the physical activity markers were predictive in young people, too. The walking study found that normal gait speed was an indicator of mortality with predictive power similar to BMI, smoking status, blood pressure, and other chronic conditions.
For this next introduction – or re-hashing, for some of you – of an essential Primal concept, I’ll be covering the three basic Primal laws of fitness (click the image to zoom in). This one can be the most difficult hurdle for some. If you’re carrying a personal history of weight gain, for example, you’re most likely somewhat inactive, too. Being overweight, you see, leads to inactivity. And yeah, being inactive can perpetuate the weight gain, but it usually starts with a bit of added weight and the sluggishness that comes along for the ride. Good times, right? They end this month.
UPDATE: Wow! Quite the response to this post! I had a good chuckle at many of the comments at first, but things have spiraled out of control a bit. First, let’s please keep things nice and civil in the comment boards. Heated arguments are one thing. Nasty ad hominem attacks are another, and they’ll be removed. Second, the reality is that if you never get within 40 yards of your target they’ll never be aware of your existence. I thought it went without saying, but don’t invade anyone’s personal space and don’t do anything else that common sense tells you not to do. I took out the line “Hide behind a tree for a second or two.” just so no one gets the wrong idea.
In most locales, summer is upon us. The sun acts as powerful beacon, a call to action for even the habitually sedentary to venture out and frolic in its rays. Hopeful mothers and fathers nudge chubby kids with creaky Xbox fingers, barely able to grasp the brand new football with which they’ve been tasked, out the door to partake in a mysterious, archaic activity known as “play.” Running shoes are finally removed from shoeboxes and attached to feet. Excuses to avoid going outside grow exceedingly pathetic and totally unconvincing, even to the skilled self-deceivers, who can no longer deny the basic awesomeness of a summer day. Squinting into this wonderful, terrible new light, they all gather in public areas – parks, hiking trails, outdoor malls, beaches – each in turn making personal pledges (or fulfilling imposed ones) that this will be the summer they finally take advantage of the great outdoors.
Last week’s post covering upper recommendations garnered so much interest – and additional questions – that I thought we’d give it another go around. While last week’s list took on basics like protein and fat as well as worthy indulgences like chocolate and – drum roll, please –BACON (break for rampant applause), this week I’ll take on a mix of specific foods and activity. Thanks for everyone’s great comments and questions last week, and be sure to weigh in on this week’s round.
This is a guest post written by Brad Kearns, my long-time friend and integral member of the Primal Blueprint team. He’ll be speaking at this year’s PrimalCon, instructing athletes and non-athletes alike on how to properly train for endurance events the Primal Blueprint way.
Greetings MDA readers. It’s been a wonderful experience to work closely with Mark Sisson over the past two years on the Primal Blueprint book and the many ambitious projects we have announced for 2010. I look forward to meeting PrimalCon attendees in April and discussing the application of Primal Blueprint principles to endurance training. Mark and I go back over two decades, when we first crossed paths on the professional triathlon circuit in the 80′s. Mark was my coach and mentor for the majority of my professional career, helping guide me into training and lifestyle practices that were counter to Conventional Wisdom (sound familiar?) and basically save me from the extreme burnout risk that was (and still is) endemic to training and racing at the elite level.
