The aim of this study was to estimate the effect of resistance training program in the fitness of untrained older women. Fourteen women in Chile (65,86 ± 6.55 kg, 1.55 ± 0.06 m, 67.71 ± 5.31 years old) underwent a program of strength training for 6 weeks, performing Back Test (BT) , Leg Press (PS), Bench Press (BP) and Knee Extension (ER) at 3 sessions per week, recording measurements before and after the period of training on maximal dynamic strength (FDM) estimated indirectly by the mass displaced in a maximal repetitions test on those exercises and maximal oxygen consumption (VO2máx) estimated by the UKK test. The results show significant differences between the pre-and post-test values (mean ± SD) of estimated VO2max (11.02 ± 7.26 and 15.57 ± 5.17 ml kg-1 min-1, P <0.05) and FDM estimated the pre-and post-tests (mean ± SD) in LS: 43.09 ± 6.19 and 51.27 ± 9.07 N (p <0.01), PB: 21,12 ± 5.77 and 29.08 ± 7.47 kg (p <0.001), ER: 18.60 ± 5.07 and 21.99 ± 5.21 kg (p <0.05) and PS: 18,60 ± 5.07 and 21.99 ± 5.21 kg (p <0.05). We conclude that the proposed training program improves the FDM in this sample of older adults.
