Previous scientific studies demonstrated the potential effect of resistance training (RT) program on blood pressure (BP) reduction and maintenance following a detraining period. This positive effect obtained with chronic RT could be associated with BP responsiveness. The aim of the present study was to evaluated BP responsiveness following RT and detraining period. Thirty-two elderly women (age 69 ?? 6 y; height 1.55 ?? 0.05 m; body mass 67.26 ?? 11.55 kg; body fat (%) 38.82 ?? 6.19) completed 10-week of RT performed two days per week, alternating upper and lower body workouts, and then 15-week of detraining period. The BP was measured by automate sphygmomanometer at pre-training, post-training and detraining moments. Participants with high and low responsiveness were classified as the 50th percentile that corresponded a decline in systolic blood pressure (SBP) higher than 8.66 mmHg or lower than 8.66 mmHg, respectively. A two-way mixed ANOVA was applied to determine the effect of responsiveness on BP change and regression to the mean was controlled. The difference on BP between groups from pre-training vs. post-training and pre-training vs. detraining were analyzed with independent t test. There was significant decrease in SBP post-training and detraining moments compared to pre-training for all subjects of the high responsiveness group (p < 0.05), and no alterations for the low responsiveness group (p > 0.05). After stratification by SBP responsiveness, high responsiveness group presented higher SBP values at pre-training (132.44 ?? 13.72 mmHg) compared to low responsiveness group (118.23 ?? 11.05 mmHg) (p= 0.001). There was a significant difference (p < 0.05) in SBP delta mean at pre-training to post-training for high responsiveness group (??= -18.56 mmHg; -13.82%) and all participants (??= -9.26 mmHg; -6.85%), without differences in the low responsiveness (??= -1.06 mmHg; -0.7%) (p > 0.05). The SBP responsiveness is probably associated to pre-training values inducing a false interpretation of results, while inadequate statistics analysis also compromises the interpretation of scientific results.
