Abstract: Osteoporosis is defined by having a T-score of -2.5 or lower on a Dual-energy X-ray Absorptiometry (DXA) test or scan [4,6].A drop in estrogen production, characteristic of the postmenopausal stage of life, is a factor that accelerates BMD reduction [7].This means that women constitute a population that is especially susceptible to primary type I (or postmenopausal) osteoporosis [8,9].In Brazil, 10% of the female population live one third or more of their lives beyond menopause; healthcare in this population includes measures focused on behavioral change and long-term investment in health [9][10][11].The prevention of this disease arouses a great deal of clinical interest, due to the continuing increase in the elderly population [3,4,12].Among the aspects that are related to good quality of life in old age is good functionality.Elderly individuals have indicated this factor as one of the most important, since it is associated with independence and autonomy [13].Recent advances in bone mass measurement techniques allow us to evaluate BMD with good accuracy, reproducibility, and a minimum exposure to radiation [10].A diagnosis of osteoporosis is based upon BMD, and makes it possible to recognize the disease at an early stage, which can provide an opportunity for early intervention with preventive measures.Most studies have demonstrated a positive correlation between exercise levels and bone mass.However cross sectional studies demonstrate simply an association and do not imply causation, benefits have been reported in women, with low BMD who have taken part in strength training [14][15][16].It is already well-recognized that resistance exercises (in individuals without nutritional impairment) can stimulate bone formation [7,11,17].However, it is necessary to know whether the supervision of physical activity can produce effective evidence regarding the effect of exercise on bone quality. ObjectiveThe objective of this study was to analyze the effectiveness of supervised and non-supervised exercise training on loss of bone AbstractThe reduction in Bone Mineral Density is important during the ageing process because it can be a potential manifestation of osteoporosis.Aim: The objective was to assess the impact of exercise on bone mineral density in women. Materials and Methods:This research was conducted under the supervision of a physical therapist focused on the bone mineral density of ageing women.One hundred women, 60 years of age or older, were included in the study and underwent bone mineral density evaluation before and after administering two types of exercise.Results: Only 58.8% of the participants had undergone bone mineral density evaluation at some time before the study, and 74.4% were sedentary.No significant difference was found between vertebral and femoral bone mineral density before and after the intervention in both groups.No correlation was found between the evolution of bone mineral density and the age of menarche.Conclusion: Exercise, with or without supervision, also helped to maintain bone mineral density in postmenopausal women, who would have a natural tendency to experience bone mineral density loss.
