Influence of Intensive Interval Training Programs on the Development of Endurance in 10-Year-Old Boys

Objectives. This study aimed to experimentally identify and evaluate the effectiveness of using intensive interval programs to develop endurance in the educational process of 10-year-old boys. Materials and methods. The research involved twenty 10-year-old boys. Control (n = 10) and experimental (n = 10) groups were created. Children and their parents were informed of the features of the study and agreed to participate in the experiment. The study protocol was approved by the ethics committee of H.S. Skovoroda Kharkiv National Pedagogical University (Kharkiv, Ukraine). This study was conducted in accordance with the Declaration of Helsinki – Ethical Principles for Medical Research Involving Human Subjects (World Medical Association Declaration of Helsinki, 2013). The following research methods were used: scientific and methodological literature analysis, pedagogical testing, and mathematical statistics to process research results. Results. According to the results of the complex control of boys’ endurance abilities, statistically significant changes in all indicators in both experimental (p < 0.001) and control groups (p < 0.05) were established. The positive dynamics of the results favoured the experimental group. The most statistically significant changes took place in the experimental group on indicators of tests “Push-ups in a lying position” by 35.2% (p < 0.001), “Jumping with a rope for 1 min” (20.8%; p < 0.001), “Squatting on two legs for 1 min” (18.8%; p < 0.001), “From a lying position rising in a saddle for 1 min” (17.4%; p < 0.01). The obtained results of the final testing in tests “Hanging on bent arms’ ”, “Burpee test in 1 min” and “300 m run” were somewhat lower and still demonstrated statistically significant changes (13.0%, 11.4%, 6.5%, respectively, at the level of significance p < 0.001). General endurance developed more slowly than other types of endurance. In “Hanging on bent arms’ ” the change in data after the experiment in the control group was statistically insignificant (p = 0.05). Conclusions. The intensive interval training method, which used specially selected exercises according to the “Tabata Protocol,” promoted endurance development in 10-year-old boys.
