Purpose. This study aims to fill a significant gap in sports science research by examining the underexplored effects ofasymmetric load training on the deep stabilisation system (DSS), strength, and maximal power in female softball players.Methods. Fourteen participants were divided into two groups: a control group (CON), which exercised with a symmetricallyweighted bar, and an experimental group (EXP), which used a bar with asymmetrically distributed weight. The asymmetricload with a distribution of weight that was gradually increased during the 8-week intervention program. The assessmentincluded a 1 repetition maximum (1RM) test for deadlift, flat bench press, front squat, and 4RM tests for single-leg leg pressfor both legs, along with evaluations of DSS and strength/performance, before and after a resistance training program.A two-way ANOVA was used to compare pre- and post-intervention performance on the DSS and 1RM strength tests.Results. The results showed significant improvements in all 1RM and 4RM tests for both groups in all exercises (p > 0.001),with no significant differences between the groups (p < 0.05). However, a dependent t-test in the EXP group revealed significantimprovements in DSS strength/performance from pre- to post-measurements in all tests, with large effect sizes. In contrast,the CON group showed significant improvements only in trunk extension, side plank, and prone tests.Conclusions. These findings indicate that asymmetric training may provide superior benefits in strengthening the DSS,while still achieving comparable gains in maximal strength.
