Assessment of the effects of specific high-intensity interval training on physical fitness and work capacity in young boxers

The purpose of the study is to examine the effectiveness of two types of specific high-intensity interval training (HIIT) on the physical fitness and performance indicators of young boxers. Research methods and organization. Young boxers utilized two types of boxing-specific HIIT during a 4-week training camp. One group engaged in HIIT with a work-to-rest interval ratio of 30 seconds to 6 seconds, while the other group used HIIT with a work-to-rest interval ratio of 20 seconds to 4 seconds. The procedures for testing the athletes' performance and physical fitness included an analysis of the boxers' actions in simulated bouts and the Burpee Fitness Test. Research results and conclusions. The results of the testing identified significant differences in performance indicators (total number of punches and time spent delivering punches) in favor of young boxers who utilized HIIT (30 s : 6 s). The conducted research allows us to assert a more significant positive effect of using boxing-specific HIIT in enhancing the performance level of young boxers in the junior age category.
