enhancing speed, agility, and anaerobic capacity via a tuja-shuttle run exercise model

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.
