“…BJJ athletes with LBP had shorter training time than BJJ athletes without LBT, which might suggest that BJJ has positive impact on body posture and LBP incidence. Similarly, to Walaszek et al (2017) found that regular 6-month judo practice had positive effect on young judo athletes’ body posture, and Grabara (2020) found that two years of volleyball training did not result in asymmetries in teenage athletes posture. de Queiroz et al (2016) found improvement of functional fitness, health and quality of life in elderly men who trained BJJ for 12 weeks.…”

“…Therefore, the natural direction of examination in searching for causes and in assessment of an athlete with back pain is the analysis of their posture. Several authors have analysed posture of athletes of different sports disciplines ( Özyürek, Bayraktar & Genç, 2018 ; Walaszek et al, 2017 ; Grabara, 2020 ; Kruusamäe et al, 2015 ; Pereira et al, 2019 ). However, no report on BJJ postural assessment had been found.…”

Background The aim of the study was to assess the prevalence of back pain in non-professional Brazilian Jiu-Jitsu practitioners (NP-BJJ practitioners), and to assess the relationship between their back pain and postural disorders. Methods The study involved 61 subjects (age: 30.7 ± 4.9 years old; body mass: 79.4 ± 12.9 kg; body height: 179.6 ± 8.4 cm; 8 woman and 53 man), 31 who trained Brazilian Jiu-Jitsu (BJJ) and 30 subjects who had never trained any combat sport. The mean time of training BJJ in the study population was 3.9 ± 4.1 years. Postural assessments were conducted with the use of the photogrammetric method. The assessment of back pain and injuries was conducted with the Oswestry Disability Index (ODI) and with our proprietary questionnaire. Results Among both populations, 37 subjects reported back pain. There were no differences in back pain location between the two groups or in functional state on the ODI. Significant differences between the groups in the values of the postural parameters (spinal height, length of kyphosis, length of lordosis, pelvis inclination angle) were observed. Statistically significant differences between the NP-BJJ practitioners with and without back pain in the length of the thoracic kyphosis and the differences in the height of the waist triangles were found. Conclusions Both in the study population and in the control group the spinal pain was minimal or moderate on the ODI. BJJ practitioners who reported back pain had characteristic postural changes in some of the analysed postural parameters in comparison to BJJ practitioners who did not report back pain.

“…From the available literature, it can be seen that children start training from preschool age. Based on the available publications, it can be concluded that the youngest participants of judo lessons in Poland are between four and six years old [ 3 , 16 , 17 ]. Similarly, in her work, Demiral [ 18 ] proposes a primary judo curriculum for children aged 4–6.…”

“…Sterkowicz-Przybycień et al [ 3 ] suggest that the duration of judo lessons for practitioners aged 4–6 should be 30–35 min twice per week. In studies by Walaszek et al [ 16 , 17 ], children aged 5–6 exercised for 35–45 min 2–3 times per week. Neofit [ 20 ] describes recommendations based on feedback and coaching experience and suggests that judo training for a group of 4–6-year-olds should take place 2–3 times per week for 45 min.…”

“…Some authors [ 3 , 16 , 19 ] suggest that judo classes could be started at the preschool age of between four and six years. Furthermore, analysing the available data [ 3 , 16 , 17 , 20 , 21 ] on the length and frequency of the training itself, the training time for preschool children (4–6 years) is between 30 min and up to even 60 min with a frequency of 2–3 times per week. At school age, authors [ 23 , 24 , 25 , 26 ] recommend extending the time from 45 to 90 min with a frequency of 3–4 times per week.…”

When organising judo training for children, it is essential to ensure maximum safety, and use an appropriate training methodology adapted to the age of the youngest judo athletes. This paper aims to review the current literature containing judo training principles and safety-related considerations for preschool (4–6 years) and school-age (7–12 years) children as an organised physical activity. Data were collected until October 2021 from eight international scientific databases (PubMed, Scopus, UpToDate, Web of Science, Cochrane, EBSCOhost, ScienceDirect, Google Scholar). In the overviews, we found various times and frequencies of judo training for children. In preschool, the training time was 30–60 min with a frequency of 2–3 times per week, whereas in the school-age group, the training time was extended from 45 to 90 min 3–4 times per week. The most common injuries included upper arm injuries, followed by those of the lower limbs. In the future, it would be an advantage to systematise the methodology of judo training as an organised form of physical activity that can complement the daily dose of exercises recommended by the World Health Organization for maintaining children’s general health.
