Study. In a 12-month trial, researchers at the University of Pittsburgh compared the effects of different durations and
intensities of exercise on weight loss and cardiorespiratory fitness in sedentary, overweight women.
Have you ever noticed that the media are constantly reporting findings from yet another nutrition research study? Knowing which types of studies are the most reliable is helpful, according to Rachel Johnson, PhD, MPH, RD, who presented on this topic at an American Dietetic Association (ADA) meeting. IDEA author Cathy Leman, RD/LD, draws on the ADA session to explain the different types of research, from the most to least reliable.
If you train elderly clients, you’re aware that preventing falls is a key motivation for them to exercise. Now there’s news that the elderly can tolerate high-force eccentric strength training and that it can decrease their risk for falls, according to research in the May 2003 issue of The Journals of Gerontology Series A: Biological Sciences and Medical Sciences (vol. 58, pp. 419-24).
researchDo you have new clients who believe that exercise must be extremely vigorous to raise their heart rate? New research by Kyle McInnis, ScD, professor of exercise science at the University of Massachusetts in Boston, found that this just isn’t so.
Walking Intensity and Bone Mineral Density
Fogleman, K.M., Borer, K.T., & Sowers, M.R. 2003. Walking intensity stimulates increases in BMD in post-menopausal women. Medicine & Science in Sports & Exercise, 35 (5, Supplement), Abstract 95.
Menopause is often associated with a loss in bone mineral density (BMD). Although exercise has been shown to increase BMD in postmenopausal women, the exact mechanism is presently unclear, as are the intensity and types of exercise that will elicit this response.
