Play it safe: Go climbing

Safer than Nordic walking.

Looking for a safe way to exercise?
Try climbing at your neighborhood climbing gym.
According to a German study of a half million visits to climbing gyms, only 30 injuries were reported, most of which were minor and none fatal. The rate of injury — 0.02 injuries per 1,000 climbing hours — was lower than surfing, skiing, badminton and Nordic walking, among other activities.
“Rock climbing, especially indoor climbing is a very safe sport,” Dr. Volker Schoffl, an associate professor of orthopedic surgery at the Klinikum Bamberg in Bamberg, Germany, and lead author of the new study, told Reuters Health. “It’s a sport that we can have all ages of people perform together, kids and grandpas can go do the sport together.”
Most of the injuries were belay-related.

Cold water thrown on ice baths
Taking an ice bath after a workout doesn’t reduce soreness or strength loss, according to a study from the University of New Hampshire.
In the study, 20 college-age guys ran for 40 minutes. Afterward, 10 took a 20-minute ice bath in 40-degree water, 10 didn’t. They then walked down stairs and were tested for quad strength, thigh circumference and levels of inflammation in their blood. The ice bathers exhibited “possible mild reduction in inflammation, but the findings were not conclusive,” according to the study.
Advises the study’s lead researcher, Naomi Cystal, “Use them sparingly. Use them in tournament situations, use them with an athlete who has done something extraordinary. But for day-to-day athletes, I wouldn’t recommend them. They’re painful, and they’re time consuming.”

Another strike against the BMI
According to a story appearing on Science Daily, “Researchers from the Perelman School of Medicine point out that the body mass index (BMI), based on the weight and height, is not an accurate measure of body fat content and does not account for critical factors that contribute to health or mortality, such as fat distribution, proportion of muscle to fat, and the sex and racial differences in body composition.”
