Aim: Optimal performance is the ultimate goal of athletes. The purpose of this study was to compare the effects of different high-intensity interval training (HIIT) protocols on athletic performance and metabolic adaptations. Methodes: The participants were divided into 4 groups: High-Intensity Running Training (HIITRUN), Sport-Specific High-Intensity training (HIITSPORT), Combined Training (HIITSPORT+RUN), and Control. The measured indicators included: maximum running speed in the 30-15 test (VIFT), maximum oxygen consumption (VO2max), the SWFT index and throws in the sport-specific wrestling fitness test, fatigue index, and maximal lactate. Comparisons between dependent variables were performed using a two-way analysis of variance (group and time) with repeated measures. Result: Significant changes in (VIFT) and VO2max were observed in HIITSPORT+RUN (P<0.05) and HIITRUN (P<0.05) compared to pre-training, control, and HIITSPORT. The fatigue index showed a significant decrease in HIITSPORT+RUN and HIITRUN compared to pre-training in the other groups. HIITSPORT+RUN (P<0.05) showed the greatest improvements in the SWFT index compared to HIITRUN and HIITSPORT, and the time-group interaction confirmed its superiority. Post-exercise lactate levels in HIITSPORT+RUN (P<0.05) were lower than in HIITRUN, but no significant difference was observed in the time-group interaction (P<0.05). The difference in maximal lactate levels before and after exercise in HIITSPORT+RUN (P<0.05) was lower compared to HIITRUN. HIITSPORT+RUN (P<0.05) showed better performance in the SWFT compared to pre-training. The fatigue index decreased in all training groups except for the control (P<0.05). Conclusion: the combined HIIT approach of sport-specific training and running is the most effective method for improving wrestlers' performance and metabolic adaptations.
