Study shows sitting increases health risks even if you're fit

By Amby Burfoot on in Health
New research measures long-term effects of sitting time.

Although dedicated runners are often confused and perhaps unhappy about the results of research regarding inactivity–”What? I have to do more than run five miles every morning?’’–the studies keep piling up. A new paper from the Journal of Physical Activity & Health has extended the findings in an important direction. It’s the first to look at ...  ... 

Endurance Training and Thyroid Function

By Alex Hutchinson on in Health
Study finds no link between training and hypothyroidism.

About two years ago, there was a bunch of controversy about running and thyroid function. In fact, there were two different controversies: (1) The idea that excessive endurance training causes your thyroid to shut down, which in turn makes you fat. (That's why marathoners are so fat, right? Oh wait...) I ...  ... 

Runners and low heart rate

By William O Roberts, MD on in Health
How regular endurance training can reduce a runner’s heart rate.

The “normal” heart rate range is usually between 60 bpm and 100 bpm and is most accurately measured when you first wake up before you begin to move around for the day. A heart rate of less than 60 is called a bradycardia, or slow heart rate. It is not unusual ... 

Stabilising Your "Foot Core"

By Alex Hutchinson on in Health
The small muscles in your feet play a big role.

We've all heard lots (perhaps too much) about the importance of core stability, provided by the network of muscles around the hips, pelvis and back. An interesting paper in this month's British Journal of Sports Medicine, from a group of researchers including Harvard's Irene Davis, makes the case that we should ... 

What's really in vitamin drinks?

By Alex Hutchinson on in Health
More than you need, study finds.

In writing about health and nutrition over the past decade or so, I've become increasingly convinced that most vitamin supplements are either useless or worse than useless. This is, of course, a vigorous ongoing debate, and I'm not pretending that it's settled. Epidemiological evidence aside, I think there's a strong ...

Fast twin, slow twin

By Alex Hutchinson on in Health
Twin studies show that fitness doesn't just depend on your genes.

I got an email from a reader yesterday about an article I wrote a few months ago on the benefits of exercise for preventing or delaying the progression of Alzheimer's disease. He was wondering, essentially, about the problem of cause and effect. Yes, people who exercise more get Alzheimer's less. But ... 

Do men and women get the same running injuries?

By Alex Hutchinson on in Health
A new study puts conventional claims to the test.

Conventional wisdom is that the male-female divide in running injuries is all about the "Q angle"–the angle that the upper half of your leg makes with vertical. Women tend to have a bigger Q angle than men thanks to their wider hips, and in theory this places greater stress on ... 

Low-fat tops low-carb diet in controlled trial

By Amby Burfoot on in Health
In "gold standard" experiment, subjects lost more weight on the low-carb diet, but more body fat on the low-fat diet.

The first controlled trial to pit a low-carb diet against a low-fat diet for weight loss has produced a somewhat split decision. The low-carb approach yielded greater weight loss, but the low-fat path yielded greater loss of body fat, widely considered the more important outcome. Here are the numbers: The low-carb ... 

Menstrual cycle and running performance

By Alex Hutchinson on in Health
How you store and use carbohydrate depends on your cycle.

After British tennis star Heather Watson was knocked out of the Australian Open in the first round last month, she blamed her poor play on "girl things." That sparked a series of articles in the British press on a generally neglected topic: the effect of menstrual cycle on athletic performance. ...
