ABSTRACT
Introduction
High-intensity interval training (HIIT) has been widely used in functional physical performance enhancement, with the characteristics of low time demand and fast effects. Currently, many ways and methods are adopted in sports training, but the impact of HIIT training still needs to be determined.
Objective
Explore the effect of HIIT on physical training.
Methods
The training content includes preparatory activities, intermittent training, and relaxation activities. The preparatory and relaxation activities of the experimental and control groups are completely the same, differentiating only the addition of a protocol with HIIT in the control group. HIIT of medium intensity was adopted.
Results
After 10 weeks of intervention, there was no significant difference in vital capacity between the experimental and control groups. Comparing the vital capacity indices of the volunteers in both groups, it was found that the vital capacity levels of the experimental and control groups showed positive differences. Still, the experimental group with HIIT had a greater gain in their vital capacity.
Conclusion
HIIT can effectively improve the functional physical performance of athletes. Level of evidence II; Therapeutic studies - investigation of treatment outcomes.
