The purpose of this study was to investigate the change of lumbar extension strength, bone mineral density and balance ability in sexagenary women with low back pain participating resistance exercise programs.
Twenty women volunteered for this study(10 women each in experimental and control group) and all they were over 60 year old with communicating and exercising independently. They performed resistance exercise programs 3 time a week for 12 weeks. Medx was used for measuring lumbar extension strength, QCT was used for measuring bone mineral density, and foot checker was used for balance ability. All data were analyzed by two-way ANOVA(MIXED) by SPSS(version 16.0). P-values of <.05 were considered significant.
Lumbar extension strength and balance ability were significantly different in exercise group(p<.05). However, bone mineral density was not significantly different in control and experimental group(p<.05).
Resistance exercise programs improved lumbar extension strength and balance ability. These result might be utilized in exercise prescription for elderly people.
