Volleyball is perceived as a physically demanding sport that involves rapid changes in speed, deceleration, and abrupt alterations in movement direction. It has been emphasized that physiological attributes such as VO2max, PIF, PEF, and FVC play a crucial role in the athletic performance of individuals participating in dynamic sports, aiding them in effectively managing critical situations. Hence, the aim of this research was to evaluate the impact of endurance training on physiological parameters among volleyball athletes. A randomized controlled trial was carried out with 24 male players (mean age 21,58; SD±2,46 years). The assessment of physiological characteristics involved the utilization of a dry spirometer for VO2max measurement and the Multistage Fitness Test for assessing PIF, PEF, and FVC. A two-way Anova analysis was executed to ascertain any disparities in physiological parameters from pre-test to post-test. The results indicated notable variances in physiological traits (VO2max, PIF, PEF, and FVC) among volleyball participants following the implementation of the Tabata intervention regimen. These metrics are instrumental in enhancing physiological capabilities to attain superior athletic performances. When designing training regimens, it is imperative to consider physiological functional elements aligned with the specific demands of the sport. Key words. VO2max; physiology; sport; exercise; Tabata training.
