## 3 Results  
Fifty-seven females were initially recruited. After screening, 15 were excluded due to not meeting the inclusion criteria. The remaining 42 were randomized to the study groups (EG = 21; CG = 21) with an average age of 43 years (SD = 9). Although the initial estimated sample size was 32 women, we recruited 42 to counteract dropouts and missing data. Nevertheless, there were no dropouts in any group. No significant differences in baseline PFM strength (\(p\) = 0.273) or any other analyzed variables were observed between groups (see Table 2). High adherence to the intervention program was found (96%), and no adverse events or effects were recorded during the intervention. After two months of the AHT program, PFM strength significantly increased in the EG (from 672.15 \(\pm\) 344.12 g at baseline to 890.25 \(\pm\) 435.80 g post-intervention; \(p\) = 0.0023) while no differences were found in CG (from 658.16 \(\pm\) 340.21 g at baseline to 587.15 \(\pm\) 356.48 g post-intervention; \(p\) = 0.1500). Table 3 shows the outcome measure results after the intervention. Table 4 shows statistically significant differences within groups for load absorption and strength measures. \begin{table}
