Getting Sporty – The Benefits for Body and Brain!

It is widely accepted that exercise has many beneficial effects on the body.  However, a new review article entitled “Exercise, Brain and Cognition Across the Lifespan” published in the Journal of Applied Physiology, highlights that the positive effects of exercise also extends to the brain, influencing cognition.  The article draws upon recent evidence which identifies physical activity as positively affecting the body and also the mind.     

Michelle W. Voss, from the University of Illinois at Urbana-Champaign and her colleagues affirmed that both aerobic exercise and strength training play an essential role in maintaining brain and cognitive health throughout life.  However, they also highlighted that this area of research still needed to be explored into understanding how certain aspects of exercise influence brain physiology and function.   

The Results

The article used the findings from 111 studies to demonstrate the effects of aerobic exercise and strength training on humans from children through to the elderly. 
It was found that aerobic exercise was crucial for getting a head start during childhood on cognitive abilities.  It suggested that physical inactivity was associated with poor academic performance, whereas, exercise programs could help to improve memory, attention and decision making.  These effects, it was argued, extend to both young and elderly adults. 

There was strong evidence that showed aerobic training benefitted executive functions, including multi-tasking, planning and inhibition, as well as improving memory.  This is particularly evident for high-intensity and high load training for older adults.  More research needs to be carried out on the effects of strength training on brain health for children. 

Animal studies, which examine the influence of aerobic exercise has found that physical activity appears to change the brain structure, promoting the growth of new nerve cells and blood vessels.  It is also recognised as increasing the production of neurochemicals, such as BDNF and IGF-1 which help to promote growth, survival and repair of brain cells. 

Clearly, the studies identify the positive effects of exercise on the brain, but the article also made clear that there were gaps in the scientific literature and more needed to be done to examine how exercise type might promote different effects on brain health and cognition at different ages. 

"It is increasingly prevalent in the print media, television, and the Internet to be bombarded with advertisements for products and programs to enhance mental and physical health in a relatively painless fashion through miracle elixirs, computer-based training, or gaming programs, or brief exercise programs," the authors say. "Although there is little convincing scientific evidence for such claims, there have been some promising developments in the scientific literature with regard to physical activity and exercise effects on cognitive and brain health."

RSPH – Sport for Health

Sir Liam Donaldson, Chief Medical Officer stated that:

“The potential benefits of physical activity to health are huge.  If a medication existed which had a similar effect, it would be regarded as a ‘wonder drug’ or ‘miracle cure’.

RSPH Training Solutions, recognises the importance of how sport can play a vital role in improving ones overall health and wellbeing.  However, the problem stems in that so many people avoid sport and thus ignore one of the cheapest and most effective ways to improve health.  Sport for Health is a programme which has been designed for people who work in sport, either in a professional or voluntary role.  It aims to help them increase the level of physical activity amongst people by understanding how an active lifestyle promotes good health and also understanding the barriers people face and ways to overcome them.
