Regular physical activity has long been found to associate to the prevention of cancer, cardiovascular disease, and other chronic diseases, but the regular walking contribution of health benefits of the younger elderly have not been explored.
Osteoporosis is defined as a condition of thinning of bone and bone tissues as a result of the loss of bone density over a long period of time. It is a widespread degenerative disease of skeletal joints and often associated with senescence invertebrates due to excessive or abnormal mechanical loading of weight-bearing joints, arising from heavy long-term use or specific injuries(1).
Regular walking has shown to reduce the prevalence of osteoporosis in older adult by keeping older people mobile and independent(2). According to the joint study led by Manchester Metropolitan University, osteoporosis and muscular weakness are decreased by regularly completing activities ranging from low-intensity walking(2).
The American College of Sports Medicine in the study of physical activity for older adults, suggested "(physical activity)improved bone health and, thus, reduction in risk for osteoporosis; improved postural stability, thereby reducing the risk of falling and associated injuries and fractures" and "The benefits associated with regular exercise and physical activity contribute to a more healthy, independent lifestyle, greatly improving the functional capacity and quality of life in this population"(3).
Dr. Buchner DM at the University of Washington School of Medicine said, "Epidemiologic evidence strongly supports a role of regular physical activity in successful aging by preserving muscle performance, promoting mobility, and reducing fall risk"(4).
In fact, exercisers with distance walked in six minutes, not only improved (p < .05) scores on an observational gait scale, Isokinetic strength in knee flexion(5), but also promoted suppression of bone turnover and reduced risk of osteoporosis, according to the study of 50 postmenopausal women, aged 49-75 years, with osteopenia/osteoporosis recruited: 32 women enter the exercise program (the exercise group) and 18 served as controls (the control group)(6).
Unfortunately, University Department of Primary Care and Population Sciences after intensive studying of brisk walking in the prevention of postmenopausal osteoporosis. insisted that brisk walking in the older adult, although reduces risk bone turn over, it is associated to risk of falling, according to the result of an investigation of 165 women drawn from the local accident and emergency departments with a history of fracture of an upper limb in the previous 2 years(7).
