Exercise really IS good for you: Jogging and cycling can preserve memory

The results from implications for the prevention and treatment of diseases such as Alzheimer’s and dementia, the researchers say.

They originate that aerobic exercise in humans led to an actual increase in the size of the Nautical port hippocampus region of the brain which is critical for memory and other perception functions.

Although the total volume of the hippocampus did not increase, exercise helped ponderous down the deterioration of the brain.

Brain health decreases with age, with the run-of-the-mill brain shrinking by approximately five per cent per decade after the age of 40.

The group from Australia’s National Institute of Complementary Medicine at Western Sydney University and the Branch of Psychology and Mental Health at the University of Manchester reviewed 14 clinical trial runs which examined the brain scans of 737 people.

Exercise can be seen as a maintenance program for the brain

The review, published in the journal NeuroImage, included a mix of healthy adults, people with tranquil cognitive impairment such as Alzheimer’s and people with a clinical diagnosis of cognitive illness including depression and schizophrenia. 

They were aged 24 to 76 years with an ordinary age of 66 and either had aerobic exercise programmes or control conditions.

The researchers explored effects of aerobic exercise, including stationary cycling, walking, and treadmill game. 

The length of the interventions ranged from three to 24 months with a roam of 2-5 sessions per week.

The Hippocampus showed consistent increases with application in early tests

Studies in mice and rats have consistently shown that true exercise increases the size of the hippocampus but until now evidence in humans has been inconsistent.

The mug up showed that aerobic exercise can improve memory function and assert brain health as we age.

Lead author, NICM postdoctoral research affiliated, Joseph Firth said the study provides some of the most absolute evidence to date on the benefits of exercise for brain health.

He said: “When you train you produce a chemical called brain-derived neurotrophic factor (BDNF), which may assistance to prevent age-related decline by reducing the deterioration of the brain.

“Our data showed that, degree than actually increasing the size of the hippocampus per se, the main ‘brain advantages’ are due to aerobic exercise slowing down the deterioration in brain size. In other tidings, exercise can be seen as a maintenance program for the brain.”

He added: “Along with make progressing regular ‘healthy’ ageing, the results have implications for the prevention of ageing-related neurodegenerative disorders such as Alzheimer’s and dementia.

«To whatever manner further research is needed to establish this.

“Interestingly, physical drilling is one of the very few ‘proven’ methods for maintaining brain size and functioning into older age.”
