Enhancing Speed, Agility, and Anaerobic Capacity via a Tuja-Shuttle Run Exercise Model

Abstract

Background: The performance of an athlete can be measured based on physical ability, functional anatomy, and sports’ characteristics and their physical bio-motor properties. Objectives: The purpose of this study was to analyze speed, agility, and anaerobic capacity after high-intensity interval training based on the Tuja-Shuttle Run exercise model and to determine the appropriate high-intensity interval training model according to the characteristics and intensity of various sports. Methods: This quantitative research employed a quasi-experimental pretest-posttest group design. The samples were 14 female handball athletes with the age range of 17 - 26 years. The treatment was given 3 times a week for 8 weeks, including high-intensity interval training using the Tuja-Shuttle Run model. Data were analyzed using paired sample t-test and SPSS version 20.0. Results: According to the paired sample t-test for comparing pretest vs. posttest, there were significant improvements in average speed (3.40 ± 0.86 vs. 3.36 ± 0.78 seconds, P ≤ 0.001), agility (16.76 ± 0.56 vs. 15.51 ± 0.59 seconds, P ≤ 0.001), and anaerobic capacity (1666.65 ± 248.14 vs. 1832.72 ± 340.25 Joules, P ≤ 0.001). Conclusions: High-intensity interval training employing the Tuja-Shuttle Run exercise model significantly increased speed, agility, and anaerobic capacity.
