dc.description.abstractBackground. Coaches predominantly utilize linear training protocols to enhance the aerobic power of football players. However, there is limited data on the effects of change of direction (COD) protocols on aerobic power in football. Objectives. This study aimed to determine which high-intensity interval training (HIIT) program- linear (LHIIT) or change of direction (COD)-has a more significant impact on increasing aerobic power in senior female football players. Methods. Sixty senior female football players were divided into two experimental groups: LHIIT (n=30) and COD (n=30). Both groups underwent a four-week HIIT protocol, with LHIIT involving linear and COD incorporating change-of-direction exercises. Aerobic power was measured using the 30-15 intermittent fitness test (IFT), maximal aerobic velocity (MAV), and VO2max at the beginning and end of the study to assess the differences in aerobic adaptations between the two programs. Results. The results indicated that the COD group eliminated the significant difference in VO2max that initially existed between the two groups, suggesting that COD protocols may be more effective in increasing aerobic power than linear ones. Additionally, both groups significantly improved the 30-15 IFT, MAV, and VO2max. Conclusion. Both linear and change-of-direction HIIT protocols significantly enhance aerobic performance in senior female football players. However, COD protocols may have a more significant impact on VO2max improvement. Future research should explore the potential effects of COD protocols on anaerobic power and seek to identify even more effective HIIT strategies for enhancing VO2max.
