CrossFit Training Impact on the Level of Special Physical Fitness of Young Athletes Practicing Judo

Abstract

The high level of individual physical fitness of athletes is one of the main factors in achieving sports success in martial arts. This study aimed to assess CrossFit training's impact on the level of physical fitness of young (16-17 years old) athletes practising judo. The athletes' competitive activity data was also assessed. The young athletes (n=33) demonstrated athletic performance at a level approaching that of elite athletes. They were randomly divided into approximately two equal groups. During the training of one of the groups (n=16), CrossFit sessions were used. The obtained data were evaluated using SJFT, the level of lactate concentration in blood and a comparative analysis of the judoists' competitive coefficients (CC). Statistical analysis was performed using the Mann-Whitney U-test. A significant (p<0.05) athletic superiority has been revealed among those who used CrossFit training in the coefficient of active combat time (СС-3) in competitive matches. SJFT indicators of both athlete groups show a positive trend. Increased dynamics of blood lactate concentrations after exercises were detected among both groups. Moreover, among the athletes who used CrossFit training, blood lactate level data were significantly (p<0.05) higher, averaging 14.54±0.51 mmol/l. The duels percentage won by athletes who used CrossFit training was considerably higher than those athletes who did not use CrossFit training (59% vs 54%).

Influence of Modern Sports Technologies upon Development of the Penitentiary Service Specialists' Physical Qualities

“…Despite the complexity and variety of loads in crossfit, experts [16,17] note that this type of fitness is becoming increasingly popular among fans of sports and healthy lifestyles. According to scientists [9,18,19], the main idea of crossfit is the functional orientation of training and, as a consequence, their maximum diversity.…”

“…The use of crossfit as a means of physical training of servicemen and law enforcement officers has been studied in scientific papers [9,16]. Thus, scientists, emphasizing the need to increase the level of enrollees' physical qualities development who desire to enter higher military educational institutions, substantiated the curriculum to improve the cadets' physical fitness by means of crossfit at the stage of initial education.…”

“…Thus, scientists, emphasizing the need to increase the level of enrollees' physical qualities development who desire to enter higher military educational institutions, substantiated the curriculum to improve the cadets' physical fitness by means of crossfit at the stage of initial education. The scientists believe that the introduction of crossfit in training, sporting and mass participation events of the cadets in the period of their initial training will contribute to the comprehensive development of motor skills of the cadets and prepare them for unexpected versatile loads that arise in the process of training and combat activities [16]. The authors in their work [21] developed a technique of forming professionally important qualities and competencies of patrol police officers using crossfit means and proved its effectiveness.…”

Justification of Using Crossfit Training in Judo

“…Есть недостаток объективных данных об объеме и содержании кроссфит-сессий в тренировочном процессе единоборцев. Специалисты указывают на различия в результатах использования кроссфиттренировок у дзюдоистов различного возраста и уровня спортивной квалификации [6]. Для определения наиболее эффективных методик повышения функциональной подготовленности единоборцев необходим качественный сравнительный анализ различных методов увеличения уровня специальной физической пригодности атлетов [16].…”

“…Известно, что оценка уровня функциональной подготовленности атлетов является неотъемлемой частью организации тренировочного процесса в различных видах спорта [2,17]. Современные методы комплексной объективной оценки уровня специальной физической подготовленности единоборцев, в том числе борцов дзюдо, представляют собой анализ результатов специальных фитнес-тестов [9,10,19] и оценку уровня концентрации лактата в крови атлетов [5,6,13]. Специальные фитнес-тесты, используемые в борьбе дзюдо, имитируют напряженную деятельность основных энергетических систем организма атлетов в условиях выполнения технико-тактических действий [18].…”
