This study aimed to compare the effects of linear and change of direction (COD) high-intensity interval training (HIIT) programs on motor performance in elite senior female football players.<br> <strong>Objectives.</strong> The objective was to investigate the differential impact of linear HIIT (LHIIT) and COD HIIT protocols on various motor performance metrics, enabling coaches and athletes to optimize training strategies based on specific performance goals.<br> <strong>Methods.</strong> The study involved 60 elite senior female football players, divided into two groups: LHIIT (n = 30) and COD (n = 30). Participants underwent pre-testing to assess their initial fitness levels, followed by a four-week HIIT training program. Performance was measured across multiple variables before and after the intervention.<br> <strong>Results.</strong> The LHIIT group significantly improved eight of nine variables, demonstrating notable enhancements in sprinting, agility, and specific plyometric abilities. The COD group significantly improved six variables, excelling in agility and velocity-related tests. However, the COD group experienced an unexpected decline in the S5m variable by 0.1.<br> <strong>Conclusion. </strong>Both linear HIIT and COD HIIT programs effectively enhance physical abilities in elite female football players, with each type of training showing specific strengths. Linear HIIT is more effective for improving sprint, agility, and plyometric abilities, whereas COD HIIT excels in agility and velocity-related performance. Coaches and athletes should select the HIIT protocol that best aligns with their specific performance needs and goals to optimize athletic performance in team sports.</div> Soccer, Performance, Agility, Plyometric Exercise, High-Intensity Interval Training, Female, Professional Athletes 0 0 http://aassjournal.com/browse.php?a_code=A-11-2326-3&slc_lang=en&sid=1 Marko Erceg 100319475328460017235 100319475328460017235 No Faculty of Kinesiology, University of Split, Split Croatia Grgur Višić grgur.visic@student.kif.hr 100319475328460017236 0009-0002-9601-8725 Yes Department of General and Applied Kinesiology, Faculty of Kinesiology, University of Zagreb, Zagreb, Croatia Fredi Fiorentini 100319475328460017237 100319475328460017237 No Faculty of Kinesiology, University of Split, Split Croatia Damir Jurko 100319475328460017238 100319475328460017238 No Faculty of Kinesiology, University of Split, Split Croatia Goran Sporiš 100319475328460017239 100319475328460017239 No Department of General and Applied Kinesiology, Faculty of Kinesiology, University of Zagreb, Zagreb, Croatia Davorin Antonić 100319475328460017240 100319475328460017240 No Department of General and Applied Kinesiology, Faculty of Kinesiology, University of Zagreb, Zagreb, Croatia Halasi Szabolcs 100319475328460017241 100319475328460017241 No Hungarian Language Teacher Training Faculty, University of Novi Sad, Subotica, Serbia Onur Akman 100319475328460017242 100319475328460017242 No Sports Science Faculty, Bayburt University, Bayburt, Turkey Goran Vučković 100319475328460017243 100319475328460017243 No Faculty of Sport, University of Ljubljana, Ljubljana, Slovenia Marko Pocrnjič 100319475328460017244 100319475328460017244 No Faculty of Sport, University of Ljubljana, Ljubljana, Slovenia
