Exercise twice a week ‘ enough to avoid stroke’
YOU do not have to be a fanatic about going to the gym to reap rewards from exercise, scientists claim.
Middle- aged women who work up a sweat a couple of times a week will find they are doing enough to protect their health – because working out more has little added benefit.
Researchers found that the physically active had lower risk

DIETING and high- intensity workouts make people more susceptible to disorders including diabetes and Alzheimer’s disease, a study suggests.
Researchers found that a compound produced by the body when dieting or fasting can block a part of the of heart disease, stroke and blood clots than women who refrained from any exercise.
But more frequent physical activity did not result in further cuts in risk, said findings in the journal Circulation.
The study showed women who performed strenuous physical activity – enough to immune system linked to inflammatory disorders such as Type 2 diabetes, atherosclerosis and Alzheimer’s disease.
The scientists, at Yale School of Medicine in the US, described how the compound betahydroxybutyrate directly cause sweating or a faster heartbeat – every three or four days were about 20 per cent less likely to develop health complications.
Exercise associated with reduced risk included walking, gardening and cycling.
Study lead author Dr Miranda Armstrong, an epidemiologist at Oxford University, said: “Inactive middle- aged women inhibits NLRP3, which is part of a complex set of proteins called the inflammasome.
The inflammasome drives the inflammatory response in several disorders, including autoimmune diseases. The findings were published online by the journal Nature Medicine. should try to do some activity regularly.
“However, to prevent heart disease, stroke and blood clots, women don’t need to do very frequent activity as this seems to provide little additional benefit.”
Participants included 1.1 million British women with no history of cancer, heart disease, stroke, blood clots, or diabetes who joined the Million Women study from 1996 to 2001.
Their average age when they signed up was 56.
The women reported what they did for exercise at the start and three years later. Researchers then examined hospital admissions and deaths in relation to their responses.
The Medical Research Council, Cancer Research and the British Heart Foundation Centre of Research Excellence in Oxford funded the study.
