BBC News | ‘Late starters’ still have much to gain by exercising
Taking up exercise in your 60s will still help stave off major ill health and dementia, research suggests. The study in the British Journal of Sports Medicine followed 3,500 healthy people at or around retirement age. Those who took up exercise were three times more likely to remain healthy over the next eight years than their sedentary peers. Exercise cut the risk of heart disease, stroke, diabetes, Alzheimer’s disease and depression. Continue.
Science Daily | At 75, would Popeye still be able to take on Bluto?
If Popeye were to age naturally like the rest of us, he would need more than just big muscles to stay independent during his senior years. When it comes to muscles and aging, the important thing is quality, not quantity, as shown by the findings of a study by Mylène Aubertin-Leheudre, PhD, a researcher at the Research Centre of the Institut universitaire de gériatrie de Montréal, affiliated with Université de Montréal.

Well | How exercise can help us learn
Over the past decade, in study after study in animals and people, exercise has been shown to improve the ability to learn and remember. But the specifics of that process have remained hazy. Is it better to exercise before you learn something new? What about during? And should the exercise be vigorous or gentle? Two new studies helpfully tackle those questions, with each reaching the conclusion that the timing and intensity of even a single bout of exercise can definitely affect your ability to remember — though not always beneficially.

Science Daily | Tired, moody and pregnant? Exercise may be the answer
Exercise may improve the mood of pregnant women and help to reduce levels of fatigue reports new research published in Psychology & Health The study, by Anca Gaston and Harry Prapavessis at the University of Western Ontario, examined whether a four week exercise intervention program would result in improvements in the psychological well-being of previously inactive pregnant women. The results were clear, with participants reporting significant improvements in their mood during the program. They also saw reduced levels of fatigue, suggesting that pregnant women should be encouraged to engage in regular exercise to improve both psychological and physical well-being. Continue.
Well | How exercise changes fat and muscle cells
Exercise promotes health, reducing most people’s risks of developing diabetes and growing obese. But just how, at a cellular level, exercise performs this beneficial magic — what physiological steps are involved and in what order — remains mysterious to a surprising degree. Several striking new studies, however, provide some clarity by showing that exercise seems able to drastically alter how genes operate. Continue.
Science Daily | Exercise may be the best medicine for Alzheimer’s Disease
New research out of the University of Maryland School of Public Health shows that exercise may improve cognitive function in those at risk for Alzheimer’s by improving the efficiency of brain activity associated with memory. Memory loss leading to Alzheimer’s disease is one of the greatest fears among older Americans. While some memory loss is normal and to be expected as we age, a diagnosis of mild cognitive impairment, or MCI, signals more substantial memory loss and a greater risk for Alzheimer’s, for which there currently is no cure.

News Bureau | Team explores the effects of exercise on ulcerative colitis
A new study indicates that aerobic exercise can lessen – or worsen – the symptoms of inflammatory bowel diseases such as ulcerative colitis, depending on the circumstances under which the exercise is undertaken. The researchers found that, in contrast to their sedentary peers, mice allowed to run freely on an exercise wheel for six weeks had fewer symptoms of colitis after exposure to a chemical agent that induces colitis symptoms in mice. However, mice forced to run at a moderate pace on a treadmill a few times per week for six weeks had more colitis symptoms and higher mortality after exposure to the agent than sedentary mice, the researchers found.

Science Daily | New guidelines for exercise in children
New guidelines highlight the amount of exercise under tens should take to reduce the risk of developing cardiovascular disease (CVD) later in life. Sixty to 85 minutes of physical activity is recommended per day, including 20 minutes of vigorous activity, reports a study published in the open access journal BMC Medicine. Childhood obesity is reaching epidemic proportions, paving the way for a generation of adults prone to ill health and CVD. Exercise is well known to reduce the risk of CVD, but current guidelines for children are based on youngsters over ten years old, and it’s unclear what would most benefit younger children. Continue.
Medical Daily | Diabetes patients up to 80% more likely to become disabled; why exercise is crucial for everyone
Exercise should be an important aspect of one’s health regimen, especially that of people with chronic diseases, like diabetes and cardiovascular disease. A new study has found that, in addition to slowing the progression of the conditions themselves, regular physical activity can reduce the chances of disability. Continue.
NIH | NIH-funded study suggests that moving more may lower stroke risk
Here’s yet another reason to get off the couch: new research findings suggest that regularly breaking a sweat may lower the risk of having a stroke. A stroke can occur when a blood vessel in the brain gets blocked. As a result, nearby brain cells will die after not getting enough oxygen and other nutrients. A number of risk factors for stroke have been identified, including smoking, high blood pressure, diabetes and being inactive. Continue.
