<![CDATA[This study aims to determine the effect of interval training on increasing VO2max of 1500-meter sprint athletes at the Semarak Athletic Center club and the Didik & Guidance club. The study is an experimental and control study with a one-group pretest and posttest design. The population of this study were 1500-meter sprint athletes at the Semarak Athletic Center and Didik & Guidance in Bengkulu City.

The results of the two-tailed t-test showed that there was a significant difference between the two groups of t-values > t-table (3.426 > 2.048) at a significance level of 5% (a = 0.05). So it is concluded that there is a significant effect of the interval training method on the VO2 max level in the experimental group. The hypothesis proposed in this study is proven to have an effect.]]>
