Effects of moderate intensity resistance training on bone mineral density and muscle strength of elderly women

Bacelar SNA, Almeida FJF, Sauaia BA, Novais TMG, Furtado AEA, Quintanilha LM, Pulcherio JOB, Filho JF, Gambassi BB Effects of Moderate Intensity Resistance Training on Bone Mineral Density and Muscle Strength of Elderly Women. JEPonline 2015;18(6):94-103. The purpose of this study was to investigate the effects of moderate intensity resistance training on bone mineral density and muscle strength in 18 elderly women with ages between 61 and 67 yrs old. The women had gone through anthropometric evaluation, bone mineral density evaluation, and muscular strength evaluation before and after a resistance training program, which consisted of 3 sets of 10 repetitions (maximum) for 10 wks. The data were statistically analyzed using the Stata / SE 11.1. Quantitative variables were expressed as mean ± standard deviation and checked for differences, using ANOVA and Student's t test (P<0.05). While the findings indicate that there was no significant difference in the changes of bone mineral density in the lumbar spine and femoral neck, the 10-wk moderate intensity resistance exercise resulted in a significant increase in muscle strength in the upper and the lower limbs of elderly women.
