Abstract
ABSTRACT Introduction: The high-intensity interval training method is believed to improve sports endurance in volleyball players due to its characteristic of alternating short periods of intense aerobic exercise and recovery. Objective: Analyze the impact of high-intensity interval training on sports endurance in volleyball players aged 18 to 19 years old. Methods: We selected 16 male volleyball athletes, and divided them into control and experimental groups. A high-intensity interval training protocol was added to the experimental group, while the control group remained with standard training. The indices of the effect of intensive interval training were measured through the sports endurance test in the athletes, comparing the results before and after the intervention. Results: The exercise index on oblique plates for 30 seconds in the experimental group increased from 58.51±1.06 to 61.17±1.44; there was a change in the 800-meter run from 2.39±0.02 to 2.33±0.02 minutes after the experiment, and the 30kg supine weightlifting in 30 seconds was from 49.93±1.99 to 53.58±1.79. However, the control group data did not change significantly. Conclusion: Long-term appropriate high-intensity interval training played an evident role in improving the endurance of volleyball players.
