Background: VO2max refers to the maximum amount of oxygen an individual can utilize during exercise. It is commonly used to test the aerobic endurance or cardiovascular fit­ness of athletes before and at the end of a training cycle. VO2max is measured in milliliters of oxygen consumed in one minute, per kilogram of body weight (mL/kg/min). This study aimed to determine the effect of High-Intensity Interval Training (HIIT) on VO2max in sedentary students.

Subjects and methods: This was a randomized controlled trial (RCT) conducted at the School of Health Polytechnic Surakarta, Central Java, from November to December 2020. A random sample of 30 students was randomly assigned into 2 groups: (1) group undertaking High-Intensity Interval Training (HIIT) and (2) group not undertaking HIIT. The dependent variable was VO2max measured by McArdle Step Test. The independent variable was High-Intensity Interval Training. The HIIT was carried out for 4 weeks with a frequency of 3 times a week. The mean difference of VO2max between the HIIT group and the none HIIT group after intervention was tested by independent t-test.

Results: The mean VO2max in the HIIT group (Mean= 35; SD= 2.40 mL/kg/min) was higher than that in the group without HIIT (Mean= 32; SD= 1.95 mL/kg/min), and it was statistically significant (p= 0.027).

Conclusion: High-Intensity Interval Training is effective in increasing VO2max in sedentary students.
