Exercise early in life—benefit later in life. That’s what researchers from Ball State University’s Human Performance Laboratory, in Indiana, concluded in a study published recently in the Journal of Applied Physiology (2013; 114 , 3–10).
Scientists looked at “whole body aerobic capacity and myocellular markers of oxidative metabolism in lifelong endurance athletes and age-matched healthy, untrained men.”
In much of the working world, people are expected to be on the job for 40 hours or more every week. People seem to respect you when you say you’re really busy. However, when putting in a hard day’s work goes awry, it translates to “crazy busy” or “I’m swamped.” And “crazy busy” is not conducive to the good health and well-being we aspire to for ourselves, our families and our clients in the fitness industry.
When it comes to optimal endurance exercise performance, fuel source and utilization play a major role in success. The contribution and expenditure of fats and carbohydrates for the synthesis of ATP (adenosine triphosphate) during exercise are regulated by several factors, including activity, duration and intensity, as well as the person’s age, training status, diet and gender. Proteins contribute a minor 1%–8% of fuel needs during submaximal exercise (Isacco, Duché & Boisseau 2012).
Are you happy in your fitness career? If you are, you have no doubt found your calling in helping others reach their full potential. Accompanying them as they persevere through difficult times and break new ground is heartwarming and meaningful to you.
You have been recruited to change a life. A young man is out of shape and headed toward a life of obesity and health complications. But he desperately wants to change. Perhaps you saw him on television during the 2012 Summer Olympics. He appeared on a Nike® commercial shot in a rural area near London, Ohio.
When I was a child growing up on a farm in the mostly snow-covered fields of Minnesota, I imagined a very different life: living in an airy house in a sunny climate, wearing flowing white clothes and welcoming many guests. In junior high, I wrote a paper on being a freelance writer. Today, I am a freelance writer in Southern California in a spacious home with plenty of guests (relatives from Minnesota!); and yes, I do like to wear white. Exactly how this life materialized seems to be part conscious determination, part cosmic mystery—and there you have the maddening beauty of manifesting.
Experts often recommend keeping smartphones and tablets out of the bedroom to improve sleep quality. While this practice may be optimal, it’s likely many people remain connected up until bedtime. Are they doomed to a life of inadequate sleep? Maybe not, say scientists from the Mayo Clinic.
Women who are coping with menopause are looking to complementary and alternative medicine (CAM) for ways to manage their symptoms, according to a review of surveys conducted between 2000 and 2012 among women worldwide. Researchers from the Korea Institute of Oriental Medicine in Daejeon, South Korea, and the University of Exeter in Exeter, United Kingdom, noted that among the 26 surveys identified internationally, many were of poor methodological quality.
A recent study is shining positive light on how to nurture the human potential for kindness and compassion. Future applications could include helping kids to reduce school bullying or aiding people with antisocial behavior problems.
Demonstrating the power of the mind-body connection, familiar music can lower stress and reduce sedative use among intensive-care-unit patients requiring ventilators, says a report in the Journal of the American Medical Association (2013; doi:10.1001/jama.2013.5670).
