Good news for procrastinators, the overworked and the overbooked—kind of.
We’re not sure if this helps or hurts us in our quest (ok, often a battle) to stay fit, but recent research seems to indicate that you don’t need to grind it out daily to get in shape—if you’re willing to pump up the intensity of your workouts. The magic, according to scientists, is in interval training, where you push yourself to max effort and heart rate for shorter bursts of time. Now, if you use this news as a handy excuse to cut back on your workout schedule but never follow through with the whole interval thing—yeah, that’s a trap we’re also trying to avoid.
Lace up those new running shoes? A recent study says that barefoot running puts less stress on your joints.
Wish we had read this before running the Bolder Boulder on Monday. Your running shoes—probably along with your skis—just might have too many miles on them—cutting down on their performance and foot protection. Your running shoes hit the wall after about 600 miles, which for fairly active runners can be six months or so.
As the temperature rises your endurance decreases, making summer workouts hard on your body. That’s why long-distance runners sit in a cold bath or wear cooling vests before a summer marathon. Scientists have yet to determine the exact reason why your body tires faster in the hot sun, but a researcher in New Zealand has discovered an easier, faster way to lower your body temp before a strenuous summer workout: Drink a sugary, icy slushie.
When a lab mouse is allowed to run around in its cage, its brainpower improves. When it’s forced into running harder than it would on its own volition, its brainpower improves even more, according to a recent New York Times blog post about a study led by researchers at National Cheng Kung University in Taiwan.
Bump skiers, rejoice! A total knee replacement may not be your fate. More orthopedic surgeons are performing partial knee replacements, also known as unicompartmental knee arthroplasty (UKA) or "uniknee," which are less invasive. Osteoarthritis of the knees, caused by wear and tear, is incredibly common in skiers.
You might remember Eva Twardokens as a ski racer (two-time Olympian, six-time national champion, bronze World Cup medalist). But these days, she’s setting new American records as a weightlifter, thanks to a fitness program called CrossFit. CrossFit is “constantly varied, high-intensity functional movement," which is to say: less fancy machinery, more old-fashioned rope-climbing, sand-bag lifting, kettle-bell throwing, etc. (Think Sylvester Stallone yoked to a plough in Rocky IV.) Though CrossFit has been around for almost a decade, it’s recently enjoyed a surge of followers.
