Meta-analysing 33 study reports, Sattelmair's team found people getting the recommended 150 minutes a week of moderate leisure-time activity were 14 percent less likely to develop coronary heart disease than the inactive, and those getting 300 minutes 20 percent less likely.

Physical activity helps fight prostate cancer
Among 2,705 men who lived at least four years after a prostate cancer diagnosis, those walking more than 90 minutes a week at a brisk pace were 46 percent less likely to die of any cause, and those with more than three hours of vigorous activity 49 percent less likely.

Physical activity cuts risk of prostate cancer death
Harvard and UCSF researchers followed 2,705 men with prostate cancer for 18 years. Those doing vigorous activity beyond 180 minutes a week were 61% less likely to die of the disease, and walking 90 or more minutes at a brisk pace tracked with 46% lower all-cause mortality.

Placebo Pill vs. Antibiotic Rifaximin, Which is Better for Irritable Bowel Syndrome?
In a trial of 1,260 people with irritable bowel syndrome but no constipation, 40 percent given two weeks of rifaximin reported relief against 32 percent of the untreated, and the benefit lasted only 10 weeks. A separate trial found 59 percent improved on a sugar pill.
Disease
Trying to Manage Heart Disease Through Physical Activity?
A CDC study found 57 percent of adults with heart disease also have arthritis, and 29 percent of those with both are physically inactive, against 21 percent with heart disease alone. Joint-friendly activity such as walking, swimming or biking may help them manage both conditions.

Physical inactivity boosts type 2 diabetes mellitus risk
A Finnish study that followed 8,182 twin pairs for 28 years found physically active people about 40 percent less likely to develop type 2 diabetes, though it was not a trial. The CDC projects nearly a third of Americans could have the disease by 2050.

Brisk walking may reduce risk of breast cancer - study
In the Nurses' Health Study, postmenopausal women whose activity equalled walking more than an hour a day were 15% less likely to develop breast cancer than those doing less; brisk walking was tied to a 10% reduction. Researchers counted 4,782 invasive cases over 20 years.

Physical Activity Cuts Breast Cancer (Death) Risk - New Studies
Christine Friedenreich's review of 73 studies found the most physically active women were at least 25 percent less likely to be diagnosed with breast cancer than the least active, with most studies showing a dose-response and recreational and household activity most protective.
Lifestyle
Physical Activity cuts breast cancer risk even in BRCA mutation carriers
Among 725 BRCA1/2 mutation carriers, self-reported lifetime sports activity was tied to a 16 percent lower breast cancer risk, a reduction the authors called statistically insignificant; those averaging 11 to 22.7 MET hours a week had a 41 percent lower risk.

Breast Cancer Awareness Month, Physical Activity, Depression, Healthcare Reform
A study in Cancer analysed 1,162,596 Danish men and found those whose wives or girlfriends were diagnosed with breast cancer were 309 percent more likely to be hospitalized for a mood disorder such as major depression, suggesting male partners need emotional and social support.
Lifestyle
Physical activity, healthy diet cut type 2 diabetes risk
Women eating one and a half extra servings of green leafy vegetables a day had a 14% lower risk of type 2 diabetes, according to a BMJ review that cannot show cause. A separate Chinese cohort found high waist-to-hip ratio and low physical activity each raised risk sharply.

Physical Activity Reduces the Risk of Early Death
A pooled analysis of the largest studies found even light or moderate activity such as walking or cycling lowers the risk of early death, by about 19 percent at the recommended 30 minutes five days a week and 24 percent at seven hours a week.
Lifestyle
Watching too much TV raises death risk
American Cancer Society epidemiologist Alpa Patel found men and women who sat longer in leisure time faced higher death risk regardless of exercise. An Australian study of 8,800 adults tied each extra daily hour of TV to 11% higher all-cause and 18% higher cardiovascular mortality.
Lifestyle
Physical activity cuts cardiovascular risk
Harvard's I.M. Lee reports that 150 minutes a week of moderate activity lowers cardiovascular risk, with longer activity bringing further reductions. A separate study following more than 120,000 adults for 14 years tied more leisure sitting to higher death rates.
Lifestyle
Sitting Too Long Boosts Death Risk
American Cancer Society researchers followed more than 123,000 adults for 14 years and found men who spent six or more leisure hours a day sitting were 25 percent more likely to die, and women 34 percent, than those sitting under three hours. The authors stress this is not a trial.
Obesity
Physical Inactivity doesn't Cause Childhood Obesity
Following 202 children for seven to ten years with accelerometers, Metcalf and colleagues reported in Archives of Disease in Childhood that fatness leads to physical inactivity, while inactivity does not necessarily lead to fatness.

Longevity Genes Help You To Live Longer, So Does Physical Activity
Tom Perls and colleagues report in Science that a model built on 150 genetic variants predicts who reaches 100 with 77 percent accuracy. The study's funder notes environment matters too, and cited research suggests highly active 65-year-olds may gain about 5.7 extra healthy years.

Physical activity helps breast cancer patients survive
A Medical Oncology meta-analysis of six studies covering 12,108 breast cancer patients found post-diagnosis physical activity was linked to 34 percent lower breast cancer mortality, 41 percent lower overall mortality and 24 percent fewer recurrences. Pre-diagnosis activity showed no such benefit.
