The activity theory, also called the implicit aging theory of ageing, adaptive theory of ageing, and behavioural theory of ageing, suggests that successful ageing takes place when old adults maintain active social interactions and keep active socially interactive relationships. Some researchers argue that humans are born optimally, with a capacity for living social lives; however, environmental conditions, life experiences, and personality traits affect how we adapt to those conditions and those forms of social interaction. For example, an Optimistic approach to life may promote longevity but pessimistically impact on health and disease.
The activity theory is the belief that people gain or lose energy depending on their activity patterns, which can change with age. This results in the “wear and tear” theory – older people tend to engage in less activity than younger people. According to the activity theory, people become more inactive as they age because their activity patterns do not match their chronological age. As a result, these individuals find it difficult to remain mentally and physically active. Older adults are more likely to suffer from chronic health conditions, such as heart disease and arthritis.
According to the activity theory, the activity level of the elderly varies with age. As people get older, their activity level declines because they become less mobile and do not feel the need to move about. A decline in activity levels is associated with a lower activity level and slower rate of declining activity level with age. This is because the reduced activity level slows down the production of growth hormones, and as a result, the elderly are not as active as younger people. They also tend to retain the muscle mass that they have lost.
According to the activity theory, the activity level of the elderly does not decline because of their age. Instead, there are changes that occur to their bodies and minds that slow their rate of activity level. Their activity level tends to decrease with age because of these changes. The decrease in activity level is due to the reduction in physical abilities and mental activities that they are able to perform. Some of these activities include cognitive functions, such as fine motor and sensory processes.
The activity level of the brain changes as one ages. The activity level of the brain depends on how active one is, its characteristics, the environment, and how well it can cope with changes. These changes cause the activity level of the brain to decline with age. If someone does not spend much time active, his brain activity will not decline as much as if he or she is active all the time.
When the brain activity of an individual declines, he becomes less mobile and less able to think and learn. His cognitive functions, such as fine motor and sensory functions, deteriorate. As a result, the person finds it difficult to move and takes more time to think things. There are also decreased activities that are required by the body.
Studies have shown that activity level is influenced by the amount of glucose in the blood stream. If a person consumes a lot of sugary foods, his activity level will be very high during the day but will decline when the sugary foods are removed. Similarly, if the person is required to burn up fat calories, his activity level will remain high during the day but will decrease when food is taken in. This is the reason why people become slim around thirty years old and do not gain weight.
People who do exercise may not appear to be more active than those who do not exercise, but this difference in activity level is actually very significant. This is because it helps them to maintain the glucose levels in their blood stream that are required for their brain to function optimally. When they increase their activity level, there is also an improvement in their memory, cognitive ability and thinking capacity. It also allows the brain to work better as they do not feel tired all the time. One must understand that there are other benefits from the activity level of a person in his or her older age and these benefits can be brought about by what is the activity theory of ageing.
