Використання тренажерного обладнання у системі позаурочних занять для розвитку силових здібностей юнаків старших класів

Strength is one of the leading physical qualities of a person, it is the basis for the development of all other motor qualities. It can be developed through the use of various exercises, namely: with the weight of one’s own body, with the weight of objects, overcoming the resistance of elastic objects, overcoming the resistance of a partner, in self-support, on strength and isometric simulators. The purpose – to determine the level of development of strength abilities in boys in grades 10-11 using training equipment in extracurricular activities. Research methods: theoretical analysis and generalization of data from literary sources, physiological research methods; anthropometric research methods; pedagogical research methods; pedagogical testing of physical fitness; methods of mathematical statistics. Results. After training, the average level of strength indicators in 15-year-olds increased to Me = 48.5 kg, and the quartile limits accordingly expanded to LQ = 43.5 kg; UQ = 53.5. A similar trend was observed in the group of 16-year-old boys: Me = 47.5 kg at the beginning with LQ = 42.5 kg; UQ = 50.5 kg, while after training the median increased to Me = 53.5 kg, and the interquartile interval shifted to LQ = 49.5 kg; UQ = 57.0 kg. In the upper block to the chest exercise, 15-year-old boys showed a median value of Me = 29.0 kg before the start of training, with an interquartile interval of LQ = 23.0 kg; UQ = 31.0 kg, indicating a wide dispersion of results and different levels of physical fitness. 16-year-old schoolchildren had higher initial indicators (Me = 36.0 kg), which increased to Me = 42.0 kg after classes. The quartile boundaries shifted from LQ = 33.0 kg; UQ = 41.0 kg to LQ = 41.0 kg; UQ = 48.0 kg, confirming an increase in the overall level of strength training. In 15-year-olds, the probability that a random result after training will be higher than any random result before training is 87.5%. In 16-year-olds: this probability is even higher – 93.75%, indicating an almost maximum improvement in indicators after completing the course. The Cliff effect was Δ = 0.87 for 15-year-olds and Δ = 1.00 for 16-year-olds, which corresponds to a “very large” practical effect. Therefore, the proposed training program provides a statistically significant and practically significant increase in the strength training of high school students. Conclusions. The study reliably demonstrated the effectiveness of systematic use of exercise equipment in extracurricular activities for the development of strength abilities in young men aged 15–16. All five tested exercises showed a significant increase in median indicators, with the increase reaching 5–9 kg depending on age and exercise. The Cliff effect size in each exercise exceeded 0.87, and in four cases reached a maximum value of 1.00, which corresponds to a “very large” practical effect.
