| Abstract | CASTRO, Eliane Aparecida de, M. Sc., Universidade Federal de Viçosa, March, 2012. Analysis of indirect methods for assessing body composition, of sarcopenia and the prevalence of cardiovascular risk factors and of the relationship between osteopenia and functional mobility of lower limbs in nonsedentary women. Advisor: Leonice Aparecida Doimo. Co-Advisors: Luciana Moreira Lima and Paulo Roberto dos Santos Amorim. The changes in body composition resulting from the aging process, include the reduction in fat-free mass, an increase in body fat and the reduction in bone mineral density. Sarcopenia corresponds to muscle mass and power reduction caused by the aging process. Maintaining an adequate amount of muscle mass and strength is an extremely important factor in this process and may mean the functional independence of the individual as well as a lower incidence of accidents due to muscle weakness. Obesity, characterized by a significant increase in body fat, is directly or indirectly related to other pathological conditions, for example, cardiovascular diseases. Osteopenia refers to a reduction in bone mass and changes in the microarchitecture of bone tissue and leads to decreased bone strength and increased risk of fracture, being associated with functional mobility which, in particular the mobility of the lower limbs, it is extremely important for walking capacity and adequate independence of the elderly. Thus the following studies were proposed: Study 1 – Objective: Verify the body fat percentage (BF%) calculated by means of six equations estimates with that obtained by dual energy X-ray absorptiometry (DXA) in middle-aged and older physically active women. Method: Sample of 46 healthy women with mean age of 65.9 ± 8.0 years. Results: Despite the strong correlation between all the equations and DXA, there was low agreement between the methods. Conclusion: Although none of the equations has been shown to be entirely reliable to estimate BF% in middle age and older women, one of the equations seemed to be more advantageous to overestimate BF% in a lesser degree than the other equations. This, from the clinical point of view, may be acceptable to lead the adoption of physical activity habits and healthier food as measures involved in the accumulation of body fat. Study 2 – Objective: Assess the prevalence of sarcopenia and association with cardiovascular risk factors in non-sedentary women. Method: The sample were distributed to control group (n = 33; 24.5 ± 2.9 years) and study group (n = 91; 61.9 ± 8.7 years). Results: Anthropometric measurements, |
