High-Intensity Interval Training Specific Programming: Effects on Wheelchair Tennis Players’ Reactive Agility

Abstract

Background: The programming of wheelchair tennis physical exercises to improve reactive agility needs to be studied more deeply. The training method must be adjusted to the characteristics of the movement of the match technique, the energy system and the type of disability. The appropriate training method is high-intensity interval training (HIIT). However, HIIT is still common. Objectives: This study aims (1) to compile HIIT-specific programming, (2) to test the effectiveness of HIIT specific programming on reactive agility. Method: This is a research development with a 4D approach. The sample was 20 wheelchair tennis athletes, male and female, aged 28-36 years, weighing 60-70 kilograms. The material experts were eight nationally licensed trainers and two academics with Doctoral degrees in tennis scientific specifications. Instruments used in this study were spider run test and Guttman scale questionnaire. Data were analyzed by CVR and Friedman formulas. Stage (1) define, conducting a study of relevant articles as a basis for finding problems; stage (2) design, designing HITT specific programs, arranging questionnaires for material expert instruments; stage (3) development, refining program arrangement, and assessing programs, by experts, with Delphi techniques; stage (4) dissemination, disseminating programs and conducting effectiveness tests. Results: It is known that the assessment items from 10 material experts show the content validity of 1.00. It is known that the effectiveness test of significance value is 0.000 0.05. Conclusion: HITT specific program has good content validity, and the effectiveness test can be said to have a significant difference in increasing the reactive agility of wheelchair tennis athletes.
