Exercise And Cognitive Function : Exercise

The article was written based on a study conducted by Smith J., et al. The article describes how the hippocampus deterioration leads to Alzheimer’s – the disease usually targets the memory of the individual, a function of the hippocampus. Physical activity has been shown to preserve the hippocampus, therefore preserving the memory of the individual. If individuals at high risk of developing Alzheimer’s (individuals that carry the genetic marker, ApoE4, for Alzheimer’s) participate in physical exercise, they can lower their risk of developing the disease. Additionally, the article provided viewers with the information about the sample, method and the results. There were 4 groups of participants who were older adults with normal cognitive functioning, aged 65-89. The groups were classified by low/high Alzheimer’s risk and low/high physical activity rates. The sample’s hippocampus and physical activity levels were tracked over the course of 18 months. Furthermore, Science Daily provided an interview with one of the authors, Smith J. and a professor at University of Pittsburgh. The interviews gave insight into the mind of the author, lending a better perspective on the article and providing direct information to

A study conducted by Harvard Medical School regarding on how could exercise help your brain and what kind of exercise will help your brain to have a better result. In this article, we learn that exercises can help your brain and can also help your memory. The researchers examined different people to try to understand what exercises could help your brain using 30 minutes section. In this study, the researchers randomly evaluate people doing exercises like cardio and compared their memory and their productivity with those that didn’t any type of exercises.

Participation in physical activity has been shown to have many health benefits for older adults; this study does not provide strong support that it protects against cognitive decline. Reports have been made that physical activity may help guard against stroke and coronary heart disease, both of which may be associated with the development of dementia. Some studies were either limited in their scope or had short follow-up times. In all they find that for older adults, physical activity alone may not protect against cognitive decline.

Research has proven that physical activity improves cognitive function and can also improve brain function throughout a lifespan. Moreover, staying physically active has so many benefits as well. For example, doing exercise and fitness activities help build cells and natural pathways to help reduce changes in memory loss or dementia. Also, it has so many health benefits including long-term improvements to the cognitive function as the young adult reaching mid

Cavanaugh and Blanchard-Fields (2015) state that there is research showing how brain plasticity can be enhanced through aerobic exercise (p.51). It is important that adults be active in their lives. A 30-minute walk or some type of physical activity will benefit them as the age. The text mentions a study done by Erickson and his colleagues in 2009 where they studied the effect of aerobic exercise on the hippocampus. They found that due to aerobic exercise it produced greater volume in the hippocampus. This is significant because the hippocampus is the part of the brain that is responsible for memory, emotions, and spatial functioning. The body does not only need physical activities to produce healthier cognitive functioning but also nutrients. The text identifies three nutrient biomarker patterns that are significant on the aging brain. These nutrients are vitamin B, C,D, and E, omega-3, and trans fat. the foods that belong to these nutrients are beneficial to the brain. Older adults should make an effort to include these nutrients into their diets. positive impacts these nutrients make are better cognitive functioning and greater brain

In the book, Spark: The Revolutionary New Science of Exercise and The Brain by Dr. John J. Ratey, MD (2008), Ratey discuses how exercise can help treat many mood disorders and how it can help strengthen our brains. This book is divided into ten chapters all with five to ten subsections in them. The chapters include: Welcome to the revolution: A Case Study on Exercise and the brain, Learning, Stress, Anxiety, Depression, Attention Deficit, Addiction, Hormonal Changers, Aging, and the Regimen.

Sport is healthy, as more and more research shows. For example, sport ensures that certain substances in the body are released, which have a significant effect on the brains. These compounds support brain functions and increase the ability to decision making process. Research has shown that elderly people who on a daily basis have a medium to heavy physical effort of at least 30 minutes have a better cognitive performance

We often hear about the physical benefits of exercise and less about the psychological benefits promoted through physical activity. In fact, multiple researches suggest that physical activity increases academic performance and supports a positive outlook that is contributive to learning gains. Physical activity stimulates various brain chemicals that leave you feeling focused, more relaxed, and happier. A recent study by Fotuhi, M. confirms that exercise enhances both neurogenesis (the creation of new brain cells in regions of the brain associated with higher-order thinking and recall) and experience-dependent synaptogenesis (the formation of synaptic connections between neurons in response to learning and sensory input from the environment). Specifically, physical activity appears to stimulate the production of a protein called brain-derived neurotrophic factor (BDNF), which helps neurons and synapses grow. In fact, BDNF has been likened to fertilizer for the brain (Conyers, M., and D. Wilson p. 40).

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

The human brain is constantly changing where many new neurons are formed while others neurons die and new synapses are created while other synapses are removed (Spalding et al., 2013). Some dendrites will withdraw while other dendrites continue branching (Killgore et al., 2013). The processes driving 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 to changes in the environment, whereas neurogenesis is the ability to create new neurons and neural connections. This dynamic process of remodeling gray matter is determined mainly by a person’s genetics and can slow down due to age (Denes, 2016). However, recent scientific evidence demonstrates other non-genetic factors that can significantly improve the development of the brain and slow down neurodegeneration (Kays et al., 2012). Physical exercise has always been linked to a person’s physical health, but many recent scientific studies shows physical exercise can also keep a person’s brain sharp. Exercise affects the brain in numerous ways by creating a flourishing environment for brain growth, aiding the release of numerous hormones, and fighting against depression, stress, and anxiety.

Physical activity has been proven to have phenomenal benefits on the human body and is an important part of a balanced lifestyle. Statistics have shown that regular exercise can prevent illness and lower one’s likelihood of being diagnosed with a series of diseases significantly. It has been ‘medically proven’ that regular exercise can reduce a subject’s chance of being diagnosed with coronary heart disease or stroke by 35%, type two diabetes by 50%, colon cancer by 50%, breast cancer by 20%, early death by 30%, osteoarthritis by 83% and a number of other life threatening illnesses. Regular exercise can improve a person’s overall wellbeing and immunity to common illnesses. During physical activity, a person’s heart rate can increase significantly and allow more oxygenated blood to be supplied to muscles. A person’s breathing rate can increase during exercise and supply more oxygen to the lungs. The increased blood flow during exercise allows the brain to function better. Exercise has many benefits to the human body and is a major factor of disease

Having a “Brain Healthy Lifestyle” (Bend, 2014) is made up of several different categories that include “physical health, brain fitness, and vitality” (Bend, 2014) as well as “balanced nutrition, stress management, and mental stimulation” (Sharpbrains, 2014). Our physical health plays a major part in brain function. Exercising our bodies, eating well, and getting the proper amount of sleep has a huge impact on our physical health. “Our brain requires 25% of the blood that is pumped by your heart. The healthier your heart is, the healthier your brain will be” (Bend, 2014). Cognitive fitness is demonstrated by uses of vocabulary, thinking, perception, and attention. It is crucial to make it a normal everyday practice to challenge our brains through new activities. Taking part in a cooking class or learning to

It is because of this high level of cognitive function that physical activity and nutrition are extremely important (McDevitt & Ormrod, 2010). They affect the child’s physical wellbeing in terms of energy levels, growth and the ability to concentrate (McDevitt & Ormrod, 2010).

The articles by Erikson et al., Gatz, Korol et al., and Draganski et al. explore the concept of increased physical activity and/or mental activity having effects on the cognitive function and development or deterioration of the brain as we age. Although I agree that physical exercise is critical in increasing cognitive function because of the health benefits it provides, as well as the increased blood flow and circulation throughout the body, I ultimately believe that a healthy brain is not achieved solely by physical exercise or mental exercise, but both. I think there is a link between physical and mental exercise, and that the combination of these two activities creates higher cognitive functioning of the mind as well as the body. The mind and body come together and meet to make an overall healthy individual.

Exercise may be one of the most important influences on your overall health to date. While the only benefits that are mainly focused on are the physical benefits, significant psychological impacts can also be linked to exercise. Although some of these benefits aren’t viewed with much enthusiasm, studies have proven that exercise can actually improve one’s quality of life greatly by increasing not only their physical health but their mental health as well. It is because of this that exercise is a
