Four New Studies Link Exercise To Healthier Aging
Four new studies published in the Archives of Internal Medicine link exercise with healthy aging, either through reduced risk or slower progression of several age-related conditions or through improvements in overall health in older age, and detail associations between physical activity and cognitive function, bone density and overall health.
Researchers point out that previous studies have linked exercise to beneficial effects on a range of conditions and diseases, including obesity, diabetes, heart disease, cancer, lung disease, arthritis, falls and fractures, that can hamper older people’s ability to get on with their day to day tasks and lead independent lives. Regular physical activity has also been associated with greater longevity as well as reduced risk of physical disability and dependence, the most important health outcome, even more than death, for most older people.

Exercise and Green Tea Decrease Depression in Breast Cancer Survivors
A recent study in the Journal of Clinical Oncology found that regular exercise and drinking green tea might play an important role in warding off depression among breast cancer survivors. Researchers examined factors related to depressions in 1,399 Chinese women who were an average of 54 and who were treated for breast cancer in Shanghai, China between April 2002 and December 2006. Six months after their diagnosis, their physical activity levels; food, tea, and alcohol consumption; cigarette smoking; and use of herbal medicines and supplements were assessed
Sixty two percent of women reported some sort of exercise and they were 20 percent less likely to be either mildly or clinically depressed. Compared with non-exercising women, the likelihood of depression was 28 percent lower among women who exercised more than 2 hours a week, and 42 percent lower among those who increased their post-diagnosis exercise time.

Treadmill Helps Parkinson’s Patients Walk Better
A new study published in the Cochrane Library found that treadmill training can help Parkinson’s patients to walk better. In Parkinson’s disease, neurons producing dopamine, an important chemical messenger in the brain, die off, leading to movement problems, tremor and rigidity. Many Parkinson’s patients have a characteristic shuffling gait, which can boost their risk of falls and fractures.
Treadmill training has been used to help improve gait in Parkinson’s patients, so to investigate, researchers identified eight studies that compared treadmill training to no treadmill training in a total of 203 Parkinson’s patients. Their analysis found that training significantly improved walking speed, stride length and walking distance. However, it did not improve the ‘cadence,’ or rhythm, of a patient’s gait. The researchers conclude that it’s unclear how long the benefits of treadmill training will last, or the best way to deliver this type of training to patients with the movement disorder.

Active Parents More Likely To Have Active Children?
According to a study published in the journal Preventive Medicine, parents’ level of physical activity is not directly associated with that of their children, but instead the direct link is between parental support and a child’s level of physical activity. For the study, 268 children ages 2 to 5 in early childhood education centers in Queensland, Australia were studied. Of these children, 156 parents or caregivers were surveyed on their parental practices, behaviors related to physical activity and demographic information.
The results indicate that active parents may be more likely to have active children because they encourage that behavior through the use of support systems and opportunities for physical activity, but there is no statistical evidence that a child is active simply because they see that their parents exercise. Researchers concluded that this underscores the need for parents to provide emotional support and opportunities for activity for their children. Regardless of whether a child is athletic or is perceived to be physically gifted, all children need opportunities and encouragement of physical activity.

Aerobic Training Improves Physical Fitness for Children with Juvenile Idiopathic Arthritis
A recent review of literature about exercise therapy in the management of juvenile idiopathic arthritis (JIA) shows that structured aerobic training or low-intensity programs do not exacerbate arthritis and can lead to improved physical fitness, quality of life and functional abilities in children and adolescents with JIA.
Children with JIA are much less active than their peers. Inactivity in pediatric patients with JIA leads to deconditioning and disability and decreased bone mass, reduced quality of life and possibly increased mortality in adulthood. Although advances in pharmacology have improved the lives of children with JIA, management should also include a moderate, consistent exercise program or more active lifestyle. Physical activity may improve exercise capacity, decrease disability in adulthood, improve quality of life and, in some patients, decrease disease parameters. Further studies are needed to assess practicality of various programs and long-term effects of exercise in children and adolescents with JIA.
