Background The purpose of this study was to examine whether the addition of a 6-week French Contrast Method (FCM) to routine soccer training affects agility, vertical jump height and 30-m sprint performance in female soccer players. Methods A pretest-posttest control-group design was used. Twenty-four female soccer players (> 3 years of playing experience; regular training) participated. The experimental group performed a 6-week FCM program in addition to routine soccer training, while the control group continued routine soccer training only. Agility, vertical jump and 30-m sprint tests were administered at baseline and post-intervention. Within the scope of the study analyses, the primary outcomes (agility, vertical jump, and sprint performance) were derived from within-group pretest-posttest comparisons, whereas the secondary outcomes were obtained from findings related to the participants' descriptive characteristics. 2 Result The group x time interaction was found to be significant in the Illinois Agility Test ( F = 16.813 , p = 0.0004 eta rho & sup2; = 0.433). Performance time decreased from 18.44 +/- 0.59 s to 17.09 +/- 0.365 (Delta = - 1.35s) in the experimental group, while the change was limited in the control group (Delta = - 0.72s) ; the mean difference between groups was - 1.13 s (95% CI: -1.54 to-0.72). A significant group x time interaction was also detected in vertical jump performance ( F = 12.415 , p = 0.002 eta rho & sup2; = 0.361), with an increase of +3.31 cm in the experimental group and +0.77 cm in the control group (between-group difference: +2.54 cm; 95% CI:-0.64 to 5.72). In contrast, the group x time interaction was not significant for the 30 m sprint performance ( F = 0.869 , p = 0.361 eta rho & sup2; = 0,038). Conclusion These results indicate that the FCM training program is effective in improving female soccer players' agility and vertical jump performance, but does not create a significant difference between groups in 30 m sprint performance. These findings not only extend the scientific literature but also provide actionable strategies for coaches and practitioners.
