Purpose: This study aims to determine the effect of High-Intensity Interval Training (HIIT) on the level of VO2 Max tennis athlete student activity unit Universitas Negeri Yogyakarta.

Methods: This research method is a pre-experimental design one group pre-test post-test design. The study population numbered 10 people and used a total sampling technique to obtain a sample size of 10 people. The research instrument used is the Multistage Fitness Test (MFT). The data analysis technique used was a paired t-test, namely by analyzing the results of the pretest and posttest before and after treatment with the same data sample. Before the t-test, the normality and homogeneity tests were first carried out.

Results: The results showed that there was an effect of High-Intensity Interval Training (HIIT) on increasing the level of VO2 Max tennis athlete student activity unit Universitas Negeri Yogyakarta. Based on the results of the paired t test, the p value (sig.) was 0.003. Significance value 0.003 < 0.05.

Conclusion: Thus it can be concluded that there is an effect of HIIT exercise on VO2 Max
