A friend on Facebook was fretting about this article in men’s fitness about what happens to your body in two weeks with no exercise.
The thing is, fitness isn’t all one thing.
Strength takes awhile to decline. But running fitness? That’s sad.
I remember once when a professor from Kinesiology came to speak to my group at the Running Room. It wasn’t particularly motivational. He was talking about fitness declines. Running is the worst, he said, for how fast you lose speed and endurance. He was also a runner but even he agreed that training for strength is better in terms of staying with you.
Ditto the person interviewed for men’s fitness.
Here is exercise physiologist and coach Scott Weiss,
“Aerobic and endurance fitness reduce a lot faster than muscle mass—it’s the performance factor that is reduced the fastest,” says Weiss. Physiologically, the changes are stark, too. Weiss says: Stroke volume (the amount of blood pumped out of the heart to the body) reduces, the size of mitochondria (the power plants within a cell, linked to fitness health) reduce by almost 50 percent, heart rate increases, cardiac output reduces, and your VO2 max—or the maximum volume of oxygen an athlete can use (a gold standard of physical fitness) decreases about one percent a day. Another setback: Your lactate threshold—or how hard and long you can work out until your muscles tell you to stop—begins to drop, says Holland. (This stinks because working out at or close to your lactate threshold is a great way to build fitness; if yours is low you won’t last very long, and thus you’ll reap fewer benefits from a gym session.) “You begin to lose endurance capability as well as the ability to perform at higher intensities,” adds Holland.
But, but, but…
Who needs to be at their speed peak in January? Is anyone racing in January? If you are, then maybe don’t take two weeks off. But most of us aren’t.
Also, yes you lose fitness but it’s a process, a journey and peaks and troughs are all part of it. It’s not up up up, fitter and faster, all of the time.
It’s also about having a well balanced life. For me that includes festive meals, time with family and friends, church on Christmas Eve, snuggling on the sofa watching The Hogfather, hot tub time, presents, cookies, new books to read in bed, playing cards and new board games.
Also, dog hikes in the snow but maybe not this year with my injured knee.
Anyway, anyway, enjoy! Life is short. Yes, stay fit but don’t let that goal suck the fun and the meaning out of the rest of your life.
How about you? Do you worry about losing fitness over the holidays?
