In last month’s issue of IDEA Fitness Journal, we reported that a significant number of older women spend much of the day in sedentary behavior. A new study looks at the relationship between sedentary living and mortality risk in a similar population
The potentially negative impact of extreme endurance events has recently been garnering attention. A new study takes a deeper look at the health profiles of event participants.
Published in PLOS ONE (doi: 10.1371/journal.pone.0083867), the Ultrarunners Longitudinal Tracking Study included 1,212 active ultramarathon runners. Participants completed a Web-based survey that asked about training protocols, medical issues and running-related injuries in the previous 12 months.
￼Did you know that getting enough zzzzzzs may actually improve your exercise performance? If you regularly cut sleep short, you may want to reconsider this practice.
Why is sleep so important for exercise, and what can you do to sleep longer and more deeply? Mike Bracko, EdD, FACSM, director of Dr. Bracko’s Fitness and of the Institute for Hockey Research, examines these questions.
Why Sleep Helps
Growing research evidence supports the theory that tai chi provides not only physical benefits but also mental benefits. In a review of tai chi studies conducted by researchers at the University of Arizona in Tucson, study authors found 10 studies that reported improvements in executive function, language, learning and/or memory among older adults who practiced tai chi regularly.
More trainers are integrating life coaching with fitness training to improve clients’ results.

“Physical fitness is the first requisite of happiness,” posited Joseph Pilates in his book Return to Life Through Contrology, first published in 1945. A recent observational study of Pilates practitioners provides support for his position.
Even in childhood I had a philosophical bent. I distinctly remember sitting at the dinner table with my twin brother and discussing with him why the dog could eat hamburger and it became “dog,” whereas we could eat hamburger and it became “us.” An interesting question for a couple of 9-year-olds to pursue. Sadly, we never figured it out.
By my early 20s I had taken up the study of yoga, and my worrisome won- dering about the big questions of mean- ing and purpose in life was becoming more refined. Now I really wanted to “understand” what life was all about.
￼A large, population-based study of Midwest adults has shown that use of certain dietary supplements, including fish oil, echinacea and coenzyme Q10, was tied to changes in subjects’ systolic and diastolic blood pressure levels.
Protecting Kidney Function
The Centers for Disease Control and Prevention states that more than 20 million U.S. citizens suffer from chronic kidney disease—the slow loss of kidney function—and that it is the ninth leading cause of death. Recently, researchers learned that exercise may slow kidney function decline in kidney disease patients.
Good news to share with clients who worry that if they don’t practice yoga daily, they won’t get results: Attending yoga class just once a week can provide positive, measurable help for people with low-back pain.
A study published in Evidence-Based Complementary and Alternative Medicine (2013; doi: 10.1155/2013/658030) reported that weekly yoga classes were as effective as twice-weekly classes for relieving low-back pain in low-income minority participants.
