Why You Should Not Ignore Aerobic Exercise

If you dislike aerobic exercise like me, then it’s time to make a change.

In my 3 years of active fitness lifestyle, aerobics is one form of exercise I find rather boring and monotonous.
I’ve met some good fitness trainers who try to make aerobic classes as lively as possible, but there are others who do not understand what aerobics is all about, and these are the ones who make aerobics seem like a huge joke.

Irrespective of how you feel about aerobic exercise, a new Australian-led study has found that it can improve memory function and maintain brain health as we age, and this is why you should not ignore aerobic exercise.

Researchers from NICM and the Division of Psychology and Mental Health at the University of Manchester in the UK, examined the effects of aerobic exercise on a region of the brain called the hippocampus, which is critical for memory and other brain functions.

Brain health decreases with age, with the average brain shrinking by approximately 5% per decade after the age of 40.

The researchers systematically reviewed 14 clinical trials which examined the brain scans of 737 people before and after aerobic exercise programs or in control conditions.

The participants included a mix of healthy adults, people with mild cognitive impairment such as Alzheimer’s and people with a clinical diagnosis of mental illness including depression and schizophrenia. Ages ranged from 24 to 76 years with an average age of 66.

The effects of aerobic exercise, including stationary cycling, walking, and treadmill running, were examined by the researchers. The length of the interventions ranged from three to 24 months with a range of 2-5 sessions per week.

Overall, the results – published in the journal NeuroImage – showed that, while exercise had no effect on total hippocampal volume, it did significantly increase the size of the left region of the hippocampus in humans.

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

“When you exercise you produce a chemical called brain-derived neurotrophic factor (BDNF), which may help to prevent age-related decline by reducing the deterioration of the brain,” Mr Firth said.

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

Mr Firth said along with improving regular ‘healthy’ ageing, the results have implications for the prevention of ageing-related neurodegenerative disorders such as Alzheimer’s and dementia – however further research is needed to establish this.

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