Comparison between functional and traditional resistance training on joint mobility, determinants of walking and muscle strength in older women.

BACKGROUND
Currently, several strength training protocols have been verified aiming improvements on functionality in older population. For this purpose, integrated exercises aimed at improving essential movements may be an interesting strategy in improving performance for daily activities. This randomised trial compared the effects of eight and twelve weeks of functional and traditional training on joint mobility, gait determinants and muscle strength, and verified the maintenance of the effects after eight weeks of detraining in the older women.


METHODS
52 elderly women were randomized into three groups: Functional Training (FT: n=19), Traditional Training (TT: n=16) and Stretching Group (SG: n=17). The data were analyzed by ANOVA with Bonferroni post hoc test.


RESULTS
The FT and TT groups obtained significant improvements in the tests of muscle strength and muscle power both after twelve weeks of intervention, as well as with SG. Only the FT presented statistically significant improvements in dynamic agility/balance (32%, p=0.000), and cardiorespiratory condition (8.71%, p=0.020) in relation to SG.


CONCLUSIONS
The experimental protocols are equally effective in improving joint mobility and strength components in active elderly women. However, FT seems to be more effective than TT in the improvement of the determinants of gait ability.
