Effects of High-Intensity Interval Training on Physical Fitness, Skills, and Tactical Performance, 12 Weeks High-Intensity Interval Training

This clinical trial aims to compare the difference between high-intensity interval training and common traditional training on physical fitness, skills, and tactical performance among college ice hockey players in China.

The main questions it aims to answer are:

* 1. How does high-intensity interval training affect the physical fitness of college ice hockey players?
* 2. How does high-intensity interval training affect the skills of college ice hockey players?
* 3. How does high-intensity interval training affect the tactical performance of college ice hockey players? Participants will be asked to do 12 weeks of high-intensity interval training and common traditional training to see if there are differences between the two and the positive effects of high-intensity interval training.

Through experimental design and quantitative research methods. This experiment will test the effectiveness of the training method by intervening in the selective fitness, skills, and tactical performance of college students using a high-intensity interval training method on the ice. The experiment will use 12 weeks of high-intensity interval training to improve the fitness, skills, and tactical performance of the intervention for ice hockey players. The experiment consists of two groups, with 20 students in the experimental group and 20 students in the control group, to compare the differences between the two groups. The experiment was divided into a discussion group and a general teaching group. The purpose of this experiment is to provide a theoretical basis for the improvement of ice hockey training methods so that college ice hockey players can obtain better competitive performance, especially in physical fitness and technique.

The experimental group (1-12 weeks) performed repeated sprint training, sprint interval training (on-ice 45-s shift length conditioning drill), a long-pass tracking drill, and a chase-the-rabbit tracking drill. There are three phases: 1-4 weeks, 5-8 weeks, and 9-12 weeks, gradually increasing the intensity of training. Similarly, the control group performed varied-pace skating (1 minute accelerated skating, 2 minutes even pace), dribbling and shooting drill (30 m), passing-catching drill (20 m), and 2 on 1 offensive drill (full rink). As in the experimental group, the same three phases were used to gradually increase the intensity.
