Mind-body professionals and other fitness pros may want to offer beneficial stress reduction services to clients—especially those who are most driven to succeed. Among both men and women, people with a type A personality—characteristic of highly competitive and achievement-oriented individuals—may have a higher risk of stroke than their more relaxed and easy-going peers, according to a study in the Journal of Neurology, Neurosurgery & Psychiatry (2012; doi: 10.1136/jnnp-2012-302420).
Do you train clients outdoors? You may want to head for verdant forests and lush, grassy settings to boost participants’ mood and energy levels. Being exposed to the color green may be one reason why exercising in nature, also referred to as green exercise, produces physical and mental rewards beyond those that come from exercise alone. Studies have shown that green exercise improves mood, self-esteem, enjoyment and motivation.
One of life’s certainties is that we’re all aging. It’s also certain, however, that not everyone ages at the same rate. According to recent research, people with type 2 diabetes show signs of aging in their cardiovascular system significantly earlier than those without the disease. Fortunately, exercise can help slow this premature aging, bringing people with type 2 diabetes more in line with others who are not diabetic, says researcher Amy Huebschmann of the University of Colorado School of Medicine.newsletter_teaser: One of life’s certainties is that we’re all aging.

A barrage of recent studies has shown the potential for high-intensity interval training to incite fat loss, increase muscular and cardiovascular strength and improve other health markers among participants. But how well does this format play out in a group setting?
Kettlebells have seen growing popularity as a total-body training tool to improve cardiovascular health and musculoskeletal fitness. Yet for all the enthusiasm among personal trainers, experimental research on the effects of KB training was scant until last year, when studies began showing up in peer-reviewed journals. This column updates IFJ readers with recent research on KB training.
Many people exercise in the water because of its low-impact nature. According to research presented in October at the Canadian Cardiovascular Congress, water exercise may provide similar cardiovascular benefits to land-based workouts.
What Is the Glycemic Index?
The glycemic index is a numerical ranking system used to measure the rate of digestion and absorption of foods and their resultant effect on blood glucose. A food that ranks high on the GI produces a large, momentary spike in glucose after the food is consumed. By contrast, a food with a low GI causes a slower, sustained rise in blood glucose.
Hall, K.D., et al. 2012. Energy balance and its components: Implications for body weight regulation. American Journal of Clinical Nutrition, 95 (4), 989–94. Energy balance represents the complex interplay between the fuel we consume and the energy we exert, which makes this balance integral to the process of losing weight.
