Brief Summary

Effects of High-Intensity Interval Training on Physical and Physiological Parameters in Adolescent Female Field Hockey Players High-Intensity Interval Training (HIIT) is a training method that alternates short periods of intense exercise with recovery periods. It is commonly used to improve athletic performance. This study investigated the effects of an 8-week HIIT program on physical and physiological performance in adolescent female field hockey players. Participants were divided into two groups: one group continued their regular field hockey training, while the other group completed additional HIIT sessions three times per week. After the intervention, the HIIT group demonstrated improvements in aerobic capacity (VO₂max), reaction time, balance, and standing long jump performance. A decrease in flexibility was observed in this group. The control group showed reductions in aerobic capacity and flexibility. The findings suggest that adding HIIT to regular field hockey training may improve several key performance parameters in adolescent female athletes.

Interventions

Circumstances distinguishing this study from other studies: Although there are studies in the literature stating that HIIT programs improve physical and physiological performance parameters in many branch athletes, there are limited studies specific to the hockey branch. The HIIT programs used in the study are simple and easy in terms of application.
