Aerobic Exercises improve the brain?
Aerobic Exercises can help to improve the health of the brain. With regular implementation of the results of Thinking and memory tests improved in a recent study.
In the current investigation, the research group around Dr. Marc J. Poulin, of the Cumming School of Medicine of the University of Calgary in Alberta, it was found that older people, even if they are actually physically very active, doing a certain way of Thinking and memory tests after six months of Aerobic exercise better. The results of the study were published in the English journal “Neurology”.
Benefit of aerobic sports program for the brain is immense
With increasing age, people build, mentally and physically. Regular exercise can counteract the effects of this removal are known. However, even if people are, in fact, very inactive and late with a aerobic sports program can be of Benefit for your brain is immense, reports the researchers.
Aerboic is supplied to our brain better with blood
The current study has shown that Aerobic to supply the brain with blood, in particular in areas that are important for the linguistic expression, and Executive functions responsible. Therefore, the results of the study could be especially important for older adults who have disorders a risk for Alzheimer’s and other forms of dementia, and brain.
206 participants were examined
The study involved 206 adults prior to the start of the six-month exercise intervention not more than four days per week at a moderate intensity for 30 minutes or less trained. It is also part of the approved participants, which are not more than two days per week with a high intensity for 20 minutes a day or less trained.
How was the process of the investigation?
The Participants had an average age of 66 years and no history of heart or memory problems. If you were Thinking at the beginning of the study and memory tests as well as ultrasound measurement of blood flow in the brain is carried out. After three months of physical Tests were carried out and at the end of the six months, the Thinking and memory tests repeated.
Intensity of the Aerobic exercise program increased
The Participants were assigned to a supervised Aerobic exercise program, which is three days a week. With the progressive implementation of the programme, you increased your Training as of, an average of 20 minutes per day to an average of at least 40 minutes a day. In addition, the Participants were asked to train once a week independently.
A Positive impact of the training
The researchers found that the Participants improved after six months of Training on Tests of Executive function, including mental flexibility and self-correction to 5.7 percent. The speaking skill is tested, how quickly you can retrieve information, rose in this period by 2.4 percent.
Positive changes after six months
Before and after six months of training, the average peak blood flow of Participants was measured to the brain with the help of ultrasound. The blood flow rose from an average of 51.3 centimeters per second (cm/sec) to an average of 52.7 cm/sec, which represents an increase of 2.8 percent. The increase in blood flow during physical exercise was associated with a series of modest but significant improvements in aspects of thought, which decrease normally with age, report the researchers.
There were limitations in the study?
A limitation of the study was that the individuals who led the Exercises, was not compared with a similar group of non-exercising individuals. So the results could be due to other factors. In addition, a part of the performed aerobic was Exercises unattended, so that the specified amount may be unreliable. (as)
