Significant changesFunctional constraints are related to one’s behavioral function such as motivation. It means that a person hold creation believes about their physical and psychological inability that shape their actions and motivations. The level of activity is very high in childhood and as a person moves towards adulthood the level of activity decreases. It is because of certain functional constraints that are present in one’s body and society. These constrain are that activity is not essential in older age and that people lose the ability to learn new things as they age. Although it is true that many physical and psychological changes occur as a person becomes old. A usual older person loses 50% of its mass by the age of 80; driving is difficult beyond the age of 27. These functional constrains the people of older adulthood from participating in sports and other physical activities, which in turn make them more lazy and inactive. Less activity results in many chronic diseases like blood pressure, diabetes, obesity and cardiovascular disease (Chodzko-Zajko et al., 2009).Many kinds of research are now being conducted which support the concept that these functional constraints are irrelevant and exercise and activity for older people are vital for a healthy body and mind. Researchers have found that if a person remains active even in older adulthood, the level of performance will be same as that of a young person. Many doctors recommend exercise for older people as this strengthens the muscles and reduce sedentary behavior (Nelson et al., 2007). The knowledge and awareness of these concepts can help older people in many ways. It will encourage the older people to participate in sports and other physical activities, and it will improve their health significantly. Leaning of new skills and abilities will make people of older adulthood more active and productive.ReferencesChodzko-Zajko, W. J., Proctor, D. N., Singh, M. A. F., Minson, C. T., Nigg, C.
