Increase of VO2 max After 8 Weeks Tuja Shuttle Run Exercise for Athletes in the 14-17 Year Age Group

Abstract

The quest to enhance athletic performance through increased VO2max levels has led to exploring various training modalities, including the Tuja Shuttle Run, an innovative adaptation of High-Intensity Interval Training (HIIT). This study aims to address these gaps by examining the impact of a tailored HIIT protocol—the Tuja Shuttle Run—on the VO2max of young athletes. A total 50 athletes from KONI Kediri district and Keeltjes Soccer Academy, aged 14-17 years were recruited to be research subjects. The development of HIIT in this research was in the form of the Tuja Shuttle Run. The Tuja Shuttle Run intervention was carried out with a frequency of 3x/week for 8 weeks. Meanwhile, VO2max was gauged using the Multi-Stage 20-m Shuttle Run Fitness Test, a field test valued for its practicality despite debates on its precision relative to laboratory measures. Statistical analysis uses paired sample t-test with a significance level of 5%. Based on the results of the paired sample t-test shows that Sig. 0.000 or p ≤ 0.001, so it can be said that there was a significant difference between the pretest and posttest on the VO2max. Implementing an 8-week Tuja Shuttle Run training program can potentially enhance VO2max in athletes aged 14-17. Based on this research, further studies need to be carried out on the effect of Tuja Shuttle Run training by comparing each sport.
