Background and Study Aim. The purpose of the work is a comparative analysis of morphological and functional indicators and characteristics of the somatotype of armwrestling athletes and street workout athletes. Material and Methods. The study involved Street Workout athletes (StW, n = 15, age - 14.87 ± 0.42 years, training experience - 1.48 ± 0.22 years) and armwrestling athletes (ArW, n = 11, age - 14.87 ± 0.42 years, training experience - 1.48 ± 0.22 years). The body length and body mass were determined. The level and harmony of physical development were assessed by the regression method. Handgrip was assessed in a static mode. The electronic handgrip dynamometer Camry EH101 (China) was used. The handgrip is determined by the maximum frequency of the grip in 10 s. The electronic device "Kepai" (China) was used to measure it. The content of muscle and adipose tissue, the level of visceral fat were determined. The body structure monitor OMRON BF-511 (Japan) was used. The handgrip index, hand impulse index, static and dynamic handgrip index were calculated. Differences were assessed using the Rosenbaum test (Q). Results. A high level of handgrip was determined for all athletes. The average value of the strength index was the StW group - more than 60% of body mass; the ArW group - more than 70% of body mass. The following indicators were observed in the ArW group: harmonious physical development had (27.27 ± 13.43)% of athletes; disharmony due to excess body mass had (45.45 ± 15.01)% of athletes; disharmony due to body mass deficit had (27.27 ± 13.43)% of athletes; normal fat content had (63.64 ± 14.50)% of athletes; low-fat content had (18.18 ± 11.63)% of athletes; high and high-fat content had (9.09 ± 8.67)% of athletes. The ArW group was characterized by high - (50.00 ± 15.81)%, high - (40.00 ± 15.49)%, and normal - (10.00 ± 9.49)%-the specific weight of muscle tissue. In the StW group, the following indicators were observed: harmonious physical development had (46.67 ± 12.88)% of athletes; disharmony due to excess body mass had (53.33 ± 12.88)% of athletes; normal fat content had (57.14 ± 13.23)% of athletes; low-fat content had (42.86 ± 13.23)% of athletes. All athletes in the StW group had a high proportion of muscle tissue. It was found that exercises with your body mass in a street workout decreased fat content compared to armwrestling. Conclusions. The results confirmed the specific effect of the sport on the body of athletes. Handgrip should be considered as a success predictor in these sports. The information content of the proposed handgrip indices for monitoring the functional state of athletes was confirmed.

Материал и методы: теоретический анализ и обобщение литературных источников; педагогическое наблюдение; анализ соревновательной деятельности; метод экспертных оценок; методы математической статистики. Для определения уровня тактической подготовленности бегунов было привлечено 20 экспертов (10 тренеров та 10 высококвалифицированных спортсменов). В исследовании принимали участие спортсмены I разряда и КМС, специализирующиеся в беге на 800 м возрастом 17-21 год (10 юношей и 10 девушек). Результаты: выявлен низкий уровень тактической подготовленности бегунов на 800 м. Установлено улучшение показателей тактической подготовленности, а именно способности анализировать информацию о своих соперниках и умение использовать ее во время соревнований, увеличение разнообразия арсенала тактических действий, повышение способности навязать сопернику свою тактику и умение быстро реагировать на ситуацию, которая изменилась, и мгновенно изменять тактические приемы в зависимости от поведения соперника. Выводы: показано положительное влияние специально направленных упражнений на уровень тактической подготовленности спортсменов. Установлено перераспределение усилий спортсменов на дистанции, увеличение средней соревновательной скорости и спортивного результата.
