Effects Of Exercise On Brain Health - 1623 Words

There is ample evidence to demonstrate that through the normal ageing process alterations to the brain in structure and function are directly related to cognitive changes (Glisky, 2007). With an increasing ageing population strategies for prevention of disease and age related cognitive decline are necessary to improve quality of life and reduce the associated healthcare costs (Australian Government Productivity Commission [AGPC], 2013). Physical exercise is known to be crucial in maintaining physiological health; it can also be used as a means of neuroprotection and assist in modifiable risk factors for improved brain health and subsequent cognitive function. This review will critically analyse current research into the effects of exercise†¦show more content†¦Smith et al. (2013) took a less studied approach to improving cognitive decline by testing the effects of aerobic exercise on adults (60-88 years old) already suffering from cognitive impairment. After 12 weeks of mode rate exercise there was an improvement of memory and neural efficiency across all subjects. As discussed at the Alzheimer’s Association International Conference [AAIC] (2012), elderly people who had reduced cadence, velocity and stride length of just 1.7cm were seen to have greater declines in cognition, memory and executive function. These gait related restrictions were associated with an overall smaller brain volume (Bridenbaugh Kressig, 2013). Having reduced mobility results in an accelerated cognitive decline as being in the same environment regularly provides little stimulus to keep the mind active. Gait restriction can be improved through physical therapy and although it may not increase lost brain volume it can assist in reducing the effects of further decline (Patla, 1991). Due to the inconsistency between studies there is no definitive exercise dosage or type that can aid in protection against dementia. However, from the evidence provided it suggests that higher levels of exercise can be used as a neuroprotective mechanism to prevent the onset ofShow MoreRelatedThe Effects Of Physical Exercise On Brain Health1572 Words   |  7 PagesThe Effects of Mental Exercise and Physical Exercise on Brain Health Physical exercise does not only promote physical appearance and the body’s health, it also promotes brain health. The brain is a dynamic organ that replaces and repairs neurons throughout life. When people engage in exercise, rarely do they think about the potential affects it has on their brain. People that work out utilize various amounts of motor skills that have been acquired gradually through practice. Those utilized motorRead MorePhysical Exercise and Cognitive Functioning in Children1691 Words   |  7 PagesThe purpose of this study is to look at if physical exercise will help the healthy cognitive development in children and adolescence and this paper will illustrate that the same facts are true for children and adolescence, and will stress the importance of exercise for children optimal brain development and growth.

A lack of physical activity leads to muscular reduction, weight gain, loss of bone strength, organ failure, and it can lead to an elevated risk for the leading causes of death, such as heart related problems and diabetes (Davis). An inactive life is bad for the human body, and very detrimental to one s health and lifestyle. On the contrar y, many physical, mental, and health benefits come with exercise.

Some dendrites will withdraw while other dendrites continue branching (Killgore et al., 2013). The processes d riving the reshaping of the brain are neuroplasticity and neurogenesis. Neuroplasticity is the brain’s lifelong ability to rewire neural connections to compensate for diseases and injuries or in response toRead More Does Exercise Help the Brain?

Stress is just a reaction to a stimulus that disturbs our physical or mental equilibrium. It is pretty much in our everyday life and we have to find a way to lower the stress. A stressful event can cause the â€Å"fight-or-flight† response, causing hormones such as adrenaline and cortisol to rush through the body. A small amount of stress, known as â€Å"acute stress,† can be exciting because it keeps us active and
