Physical activity is proven to improve overall health and increase the quality and expectancy of life in participants. People who take part in exercise regularly increase the activity of the frontal region of their brains which operates memory, and the risk of developing Alzheimer’s disease is significantly decreased. Studies indicate that exercising raises the count of T-lymphocytes (T-cells) in the immune system, making the body more resistant to viruses. Weight training and cardiovascular exercise increase strength of muscles and the heart and eliminates excessive weight gain and heart disease. Some studies suggest people who participate in regular physical activity live two to three years longer.

Benefits of Physical Activity
Whether it is for sports, good health, or simply something fun to do, physical activities improve lifestyles in more than one area. Physical activity can keep the body looking good and the mental outlook more positive about life. People can reduce their weight, perform everyday tasks, and can live a better life with the incorporation of physical activity. Research on exercise has shown that by participating in regular activity the risks of becoming ill can be reduced. When a person is sick, sometimes the body cannot fight off infection, but participating in regular physical activity improves the function of the immune system to fight off the infection. Physical activity is also proven to help maintain the function of fine motor skills that people use every day. In doing this, the memory of older people can improve and the risk of developing Alzheimer’s disease can be reduced. As people age, memory is not the only aspect of the body that starts to deteriorate. With age, the joints of the body begin to deteriorate, movement slows, and the risk of high blood pressure and disease increase due to a sedentary lifestyle. By increasing physical activity in everyday life, people can maintain a healthy lifestyle and accomplish their daily routines without increased difficulty. As anything else in life, the better taken care of something is, the longer it lasts. The body is similar in that the better a person takes care of the body, the longer the life expectancy. Physical activity is proven to help prevent Alzheimer’s disease, increase life expectancy, and boost the immune system.

Physical activity tests show positive results in preventing Alzheimer’s disease. Scientists state that the frontal region of the brain is the area which houses the working memory. As this region of the brain deteriorates, the ability to remember events, people, or places decreases and Alzheimer’s disease begins to develop (Rabins, 2009). Research indicates that exercise increases activity in the frontal regions of the brain. Keeping this region of the brain working ensures that all of the functions of that region are functioning better including memory. Alternative studies also indicate that exercise helps retain fine motor skills and language skills that people use every day. Exercise of any kind increases the flow of blood to brain which carries oxygen to fuel the functions of the brain (Rabins, 2009). A lack of oxygen diminishes the possibilities of the frontal regions of the brain, therefore, the ability to retain information slowly deteriorates. Memory loss is not the only symptom of Alzheimer’s disease. Individuals affected by Alzheimer’s usually lack physical activity and experience health related symptoms including muscle deterioration, low blood pressure, and constipation. Physical activity does not need to be intense; it can include as simple an exercise as walking around the mall, dancing, or activities around the home including gardening, vacuuming, and folding clothes (Rabins, 2009).
