Peripheral arterial disease (PAD) occurs when plaque accumulates in the arteries of the legs. Reduced blood flow and loss of oxygen in the tissues beyond the obstruction cause localized muscular pain, or claudication, especially during exercise (Bulmer & Coombes 2004; Womack & Gardner 2003).
According to the Food Research and Action Center website, one quarter of U.S. children aged 2–5 are overweight or obese. Researchers from the University of Illinois, Urbana, believe they have identified the top risk factors for preschool-age obesity.
The investigators surveyed 329 parent-child pairs, asking about demographics, health histories and feeding habits. There were also home visits in which assistants gathered height and weight measurements.
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
Significant research [that has been reported in this column] supports the role of moderate exercise as an adjunctive ther- apy for adults with depression. New research shows that these same benefits may be available for teens who suffer from this condition.
Women We know that regular exercise can provide a variety of significant benefits. However, a recent study has discov- ered that older women have not been inspired to become more active.
Published in The Journal of the American Medical Association (2013: 310 , 2562– 63), the study included 7,247 women (average age, 71). Each participant was given an accelerometer to wear for 7 days. The women were then asked to complete a diary detail- ing which days they wore the accelerometers and for how long.
New research from the University of Navarra in Spain shows that exercise can have a significant positive impact on older seniors.
Scientists recruited 24 adults aged 91–96 and divided them into a nonexercise control group and a “multicomponent” exercise group. The primary focus was to learn how exercise would impact “muscle power output, muscle mass, and muscle tissue attenuation; the risk of falls; and functional outcomes in frail nonagenarians.”
What makes us weaken with age? The prime culprit is sarcopenia—age-related loss of muscle mass, strength, power and function (Sayer et al. 2013; Morley 2012). Morley (2012) says 5%–13% of 60- to 70-year-olds and 11%–50% of people in their 80s have sarcopenia, which means “poverty of flesh.”
Many experts believe that long-term healthy behaviors are more likely to take hold when developed at a young age. According to researchers from Bogotá, Colombia, learning those behaviors from Sesame Street characters might be one way to get young kids on the right track.
