Literature Review- Gerontology; Benefits of Physical Activity in Older Age - Essay Example Mees (2003) reported that in the United States â€Å"each year, musculoskeletal conditions and injuries account for about 102.3 million visits to physician offices, 10.2 million hospital outpatient visits, 25 million emergency department visits, 3 million hospitalizations, and 7.5 million procedures, and they cost an estimated $300 billion†. She goes to report that â€Å" people in their 50s notice more aches and pains after performing the same activities that were painless in their 40s, and those in their 60s cant do as much as they did in their 50s†. Because the ageing process is multidirectional and multidimensional, in examining the effect of physical activity on the process we must examine the many aspects of health that are affected as one gets older, the different types of physical activity that can be beneficial, and how can elderly people be more motivated to engage in physical activity to help them in the ageing process. Even if there is no disease present there are so many other effects on the body of ageing. Coronary artery disease, hypertension, congestive heart failure, type 2 diabetes mellitus, osteoarthritis, osteoporosis, and cognitive disorders are some of the disorders that become more prevalent as people age. Brennan (2002) describes some of the normal physiological changes that occur in the body during ageing as â€Å"changes in the cardiovascular system include decreased elasticity in blood vessel walls, increases in blood pressure, and myocardial hypertrophy resulting in decreased end-diastolic filling and cardiac output; pulmonary effects include loss of tissue elasticity as well as a gradual decline in the number of alveolar sacs†. In addition he says that â€Å"as humans age, they experience neuronal cell loss, decreases in reaction time, decreases in overall balance, and decreases in nerve conduction velocities. Aging decreases estrogen, androgen, and growth hormone levels. Rates of depression increase with
