ABSTRACT
Introduction:
Handball is a competitive sport with high demands on the physical fitness of its athletes, being physical exercise demands continuous quality improvement of its practitioners.
Objective:
Explore the effect of high-intensity interval training on physical fitness in young handball players.
Methods:
In this paper, 46 young handball players were randomly selected for the research. The volunteers were randomly divided into two different groups: the experimental group and the control group. The control group mainly performed regular physical exercises. While the experimental group performed a protocol with high-intensity interval training. Both groups underwent a basic fitness test before and after the experiment. All experimental data were statistically analyzed and discussed.
Results:
After 12 weeks of experimental intervention, the experimental group showed significant differences in three items, namely reentry sensitivity, vertical jump, and long position jump (P<0.05). In the comparison between the groups, the scores in straight thrust and long jump were also significant (P<0.05).
Conclusion:
High-intensity interval training proved effective in improving young handball players’ physical fitness. Level of evidence II; Therapeutic studies - investigation of treatment outcomes.
