Often, loneliness is accompanied by a sedentary lifestyle, which can significantly weaken one’s health. Simple exercise such as walking regularly at a good pace can’t just cut the risk of cardiovascular and Alzheimer’s disease by 50 percent — it can also clearly slow down the normal aging process of an older person’s brain, Kirk Erickson of the University of Pittsburgh told AFP. At the conference, the assistant professor of psychology presented new details of a study published in 2011 that involved 120 people aged 65 and older. – Older brain ‘highly modifiable’ – With age, the brain shrinks, he said. Physical activity, however, helps improve its overall functioning and, in particular, increases the volume of the hippocampus by 2 percent, which reverses cerebral aging by one to two years and boosts mental capacities.

Disability rises with age, with around 6 per cent of p90X3 workout children disabled, compared to 16 per cent of working age adults and 45 per cent of pensioners. There is growing evidence which suggests too much sitting – as opposed to insufficient activity – may be a new risk factor for premature death and illness. Prof Dunlop said she was surprised by the findings. It means older adults need to reduce the amount of time they spend sitting, whether in front of the TV or at the computer, regardless of their participation in http://www.sbwire.com/press-releases/p90x3-reviews/sbwire-455028.htm moderate or vigorous activity she said.

Exercise to beat dementia: Regular physical activity ‘boosts brain regeneration’
It might be increased blood flow or an increase in the number of neurons or other kinds of brain cells. While there was a 2 per cent average increase in volume within the exercise group, the same brain regions shrunk by about 1.5 per cent in the group who did not take part in the exercise regime, which is the normal rate of shrinking for this age range, Professor Erickson said. “You don’t need highly vigorous physical activity to see these effects. People are misled into believing they need years of vigorous physical exercise.
