Abstract
Background and Study Aim. Considering the growing interest in high-intensity training (HIT) among the youth, it is crucial to explore its impact not only on improving physical fitness but also on the overall health of adolescents. The aim of this study was to assess how HIT can contribute to the development of physical qualities in adolescents while minimizing the risks of excessive strain.
Materials and Methods. The study encompassed 28 students (14±0.9 years) from a lyceum in Kharkiv, Ukraine. The participants were divided into a control group (CG, n=14; including boys - n=7 and girls n=7) and an experimental group (EG, n=14; including boys - n=7 and girls n=7). The EG participated in high-intensity training sessions twice a week, with each session lasting 20 minutes. The program's effectiveness was evaluated using a series of physical ability tests. PyCharm Community Edition integrated development environment was used for the analysis and visualization of the obtained data. The software code was written in Python. The experiment was conducted in Kharkiv (Ukraine), located in a war zone since February 2022. The requirements of the military administration for ensuring the safety of experiment participants were observed.
Results. After the training program, boys from the EG showed improvement in tests on speed, coordination, and motor skills (p<0.05). Girls in the EG demonstrated significant improvement in the "Sit-up from a sitting position in 30 seconds" test (p<0.05), as well as improvements in speed and coordination tests.
Conclusions. High-intensity workouts can be effectively integrated into the physical education program for teenagers, provided that caution is exercised and the workload is monitored. The results confirm that such an approach contributes to the development of physical qualities and supports the health of teenagers. This suggests a nuanced understanding of how such programs can be optimized for different genders to enhance physical education outcomes.
