1 Solution To Obesity: Muscles That Act As An Energy Drain

Many people have traded in their gas-guzzling old "clunkers" for newer and more efficient models or cut back on energy use at home by opting for Energy Star appliances and compact fluorescent light bulbs. But, when it comes to our muscles, a little less efficiency might be just what the doctor ordered, suggests a report in the January Cell Metabolism, a Cell Press publication. The researchers from the Mayo Clinic and the University of Iowa have new insight into an important "fuel gauge" in muscle. They've also uncovered evidence in mice that treatments designed to disrupt those so-called sarcolemmal ATP-sensitive K+ (KATP) channels specifically in muscles might allow us to control our weight by increasing the number of calories our muscles will burn with regular activity or exercise.

A Lifetime Of Inactivity Be The Result Of Having A Negative Phys Ed Teacher

Humiliation in physical education class as a child can turn people off fitness for good, according to a University of Alberta researcher. Billy Strean, a professor in the U of A's Faculty of Physical Education and Recreation, says a negative lifelong attitude towards physical activity can be determined by either a good or a bad experience, based on the personal characteristics of the coach or instructor. For example, negative experiences may come from a teacher who has low energy, is unfair and/or someone who embarrasses students. During his research, Strean heard from individuals who opened up about negative experiences with coaches and instructors, some from many years ago.

Skiers, Snowboarders Should Be Aware Of Injury Risks

"There is always a risk of suffering injuries during physical activities, and skiing and snowboarding are no exception, " said orthotraumatologist Wade Smith, Vice-Chairman of Orthopedics for Geisinger Health System.

One-Third Of NFL Players With Achilles Tendon Injuries Sidelined

More than a third of National Football League (NFL) players who sustained an Achilles tendon injury were never able to return to professional play according to research in the current issue of Foot & Ankle Specialist (published by SAGE). The injured players who did return to active play averaged a 50% reduction in their power ratings. The aim of the study was to document the epidemiology of Achilles tendon ruptures in the NFL and to quantify the impact of these injuries on player performance. Previous studies have looked at the occurrence of Achilles tendon ruptures in elite athletes in general, but very little was known about how often that type of injury occurred specifically in the NFL or how it affected the athlete's future ability to play.

Fit VS. Fat: New Research Sheds Light On Debate

Although proper nutrition alone can lead to weight loss, it doesn't necessarily equal true health or fitness, says a new study in the January issue of the official journal of the American College of Sports Medicine. Enette Larson-Meyer, Ph.D., R.D., FACSM, directed 36 overweight (not obese) adults to participate in one of three programs during a six-month intervention: diet alone, diet plus exercise, or a weight-maintenance program (control group). The diet-only and weight maintenance groups were instructed not to change their physical activity regimens during the six-month period. Although both the diet and diet-plus-exercise groups lost weight during the course of the study - around 10 percent of total body weight - only the exercising individuals improved their internal fitness in addition to their waistlines.
