The aim of this pilot study was to examine the effectiveness of a CrossFit-based training program to enhance the general and sport-specific physical fitness of 10–12-year-old judokas. The study was conducted between September 2021 and February 2022. The pedagogical research experiment was designed to be one complete, annual macrocycle (September–June). The current study presents mid-point data. Twenty male participants (3 years average sports experience; age = 11 ± 0.64 years) were randomly assigned to one of two groups: CrossFit-based training (experimental, n = 10) and traditional training (control, n = 10). Baseline testing was conducted by the researcher and included tests for motor skills and general physical fitness domains including Sweden wall pull-ups and leg raises, push-ups, long jump, squats, burpees, shuttle run, and forward rolls. Judo-specific tests included O Soto Gari and O Goshi throws. CrossFit-based training was implemented twice per week for 15–20 min in the experimental group after usual training. The control group completed traditional methods of physical fitness training for judokas with the same training load regarding time. Experimental group participants significantly improved on leg raises (p < 0.01), push-ups (p < 0.05), and shuttle run (p < 0.001); the control group improved their shuttle run (p < 0.001). Only the experimental group improved on the O Soto Gari (p < 0.01) and O Goshi throws (p < 0.05). Results showed that the use of CrossFit-based trainings had a positive effect on 10–12-year-old judokas’ speed-strength abilities, speed-strength endurance, and muscular strength.

Background. According to the data from the World Health Organization, the condition of children's feet is unsatisfactory. An effective solution to this problem requires the development of pedagogic and health correction technologies, the basis of which should consist of the joint effort of orthopedists, coaches and the family, founded on the advice of orthopedists, therapeutic swimming and corrective gymnastics. The aim of this research is to study the effectiveness of the technology of orthopedist-coach-parent joint activity in correcting foot problems in children between the ages of 11 and 12. Material and methods. The condition of the locomotor system in children was assessed using the plantographic method. In order to correct foot disorders, a program was developed whose effectiveness was studied in a scientific pedagogical experiment. Results. As a result of the pedagogical experiment, the indicators of the first degree of flat feet of all 5 children in the experimental group were significantly reduced, and no significant improvement was recorded in the control group. Conclusions. The results of the research showed that the correction of deviations in the locomotor system is more effective if it is carried out as a result of collaboration between the orthopedist, a coach and parents, using therapeutic swimming and corrective gymnastics, as well as maintaining the orthopedic regime.

The panel research is a topic of considerable interest for the theory of physical education and sport, as a kind of longitudinal research carried out for the same pool of test subjects employing the single method with certain time intervals. This research provides more objective and comprehensive overview of trends in studied indicators. The aim of research: to reveal the effect of long-term physical exercise intervention on trends in the indicators of spatial, force and temporal movement parameter control in adult and elderly women. Organization and methods. We carried out panel studies within a recreational group for women at Armenian State Institute of Physical Culture and Sport, in November 2011 and 2019. The same pool of participants assigned to two age groups took part in the educational experiment. The first group was women aged 50.9 years (adults), the second group – women aged 66.8 years (elderly). We used the following research methods: study and analysis of scientific and practical literature, kinematometry, dynamometry, chronometry, mathematical statistics. Research outcomes: The findings related to the trends in differentiation accuracy indicators of spatial, force and temporal movement parameters in adult and elderly women in the framework of an eight-year panel study demonstrate insignificant and invalid changes of studied indicators. At the same time, a wide spread of individual indicators occurs in both age groups. It reflects the mixed impact of involution processes on the individual abilities to control various movement characteristics, especially common for women over 66.8 years of age. Conclusions. The research revealed that long-term physical exercise intervention comprehensively influencing on motor abilities of adult and elderly women enable maintenance of the ability to control various movement parameters on a certain level, in spite of some controversial changes.

It is known that the main goal of the training process is to achieve high sports results. Despite numerous studies conducted in judo, many issues are not well understood, including the impact of CrossFit-trainings on the technical and competitive performance of young judokas. The aim of the research is to reveal the influence of CrossFit-trainings on the competitive results of 12-year-old judokas. To reveal the influence of CrossFit-trainings on the competitive performance of teenage judokas a pedagogical experiment was carried out at the youth sports and cultural training center in Hrazdan. In the experimental group, CrossFit-trainings were introduced as the main means of physical fitness for judokas at the age of 10-12, and in the control group, traditional training methods were used. The duration of the experimental program was one training year. A total of 80 training sessions were held. In order to identify the effectiveness of the implemented training system for the technical fitness of athletes, professional assessment of two basic techniques was carried out with the participation of three specialists. The competitive success of the athletes in the experimental group clearly exceeded the performance of the athletes of the control group. This indicates the effectiveness of building a training program that includes CrossFit trainings, which, with the same technical fitness of the judokas of the two groups, had a major impact on the higher competitive achievements of the athletes of the experimental group.
