Although devices such as the Exer-Genie\u00ae are frequently implemented in resisted sprint training, scientific evidence regarding their effectiveness in adolescent female athletes remains limited. Therefore, this study aimed to examine the effects of an eight-week Exer-Genie\u00ae-assisted speed and agility\u2013balance\u2013coordination (ABC drill) training program on sprint performance, hamstring muscle strength, and vertical jump performance in young female football players.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>\n                      A total of 37 licensed female football players competing in the Turkish Women\u2019s Second League (mean age = 14.4 \u00b1 1.4 years) voluntarily participated in the study.

The experimental group completed an Exer-Genie\u00ae-assisted sprint and agility\u2013balance\u2013coordination training program twice per week for eight weeks, while the control group continued their regular training.
