Want to help your client get the most out of her exercise session? Get her a partner, says new research.
The purpose of the study, published in the Annals of Behavioral Medicine (2012; 44, 151–59), was to see if there was an ideal scenario for motivating exercisers to intensify their workouts. To determine this, the researchers randomly divided 58 female subjects among three scenarios: solo exercise; coactive (exercising independently alongside another person); or conjunctive (exercising with a partner perceived to possess greater capability).
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.

Kettlebell training has experienced a resurgence of late. Going by the physical improvements the training can offer, is its popularity warranted? The answer is yes, according to a study published recently in the Journal of Strength & Conditioning Research (2012; 26 , 2228–33).
The scientists’ goal was to determine what effects the kettlebell swing had on maximal and explosive strength. They employed half-squat
1-repetition maximum and vertical jump height as assessment markers.
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.
