A research study was conducted on a sample of 110 male and female participants aged 11 and 12 years (±1.2 years) to compare two different methods for identifying spinal deformities. The aim was to determine which of the two methods is better and more applicable in practical school conditions. The methods compared were Napoleon Wolanski's method with 8 variables and the 3D method from Contemplas GmbH TEMPLO General Motion, assessed with a total of 11 variables. By analyzing the table of central dispersion parameters of body posture according to Napoleon Wolanski's method, the participants were classified into 5 groups based on the results. Participants with scores up to 8 points were considered to have good posture, while those with scores from 9 to 16 points were treated as having poor posture. The research revealed that a total of 66 out of 110 participants had poor posture, accounting for 60%. Results from the Contemplas method showed deviations from proper posture in almost all variables. The analysis indicated significant deviations in shoulder rotation, pelvic rotation, sagittal distances, and flexion/extension variables. Overall, the results demonstrated a high prevalence of body deformities in 11- and 12-year-old students. Analyzing the results of both methods for determining body deformities, it can be confidently stated that the frequency of body deformities in students aged 11 and 12 is significantly high. Napoleon Wolanski's method identified that 60% of participants had some form of spinal deformity, while the Contemplas method showed more pronounced results, with some variables indicating deformations in 80-85% of participants. Despite providing more detailed information about students' posture, the Contemplas method is less applicable in practical school conditions due to its significant cost. Therefore, Napoleon Wolanski's method remains indispensable in school settings.

Purpose: The main aim of this study was to examine and analyse the body composition of young soccer players across different age groups. Methods: A cross-sectional study was carried out among 126 young soccer players divided into age categories: U15 – 53 players (age=14.68±0.47); U17 – 51 players (age=16.47±0.50); U19 – 22 players (age=18.05±0.38). The subjects’ height was measured using an anthropometer, while their body composition was measured using the TANITA BC-420MA digital scale. Results: On average, soccer players in the U15 group had significantly lower body height, weight, body mass index and fat free mass than U17 and U19 players, but had a higher percentage of body fat (p < 0.05). In addition to the percent of body fat mass, which tends to significantly decrease with age, the results also demonstrate significant non-linear increases in body height, weight, and lean body composition concurrent with the players’ ages. Conclusion: These results indicate that younger soccer players have lower absolute values of morphological characteristics compared to senior players.

Background and Study Aim. Musculoskeletal disorders (MSD) are incredibly common and are often related to work load. For any occupational or public health intervention, injury prevention is preferred to injury treatment. Occupational health and injury prevention research has the potential to help mitigate MSD in the workplace. The aim of this study was to determine how the work demands of ski instructors may affect the health of their musculoskeletal system. Material and Methods. A cross-sectional study involved the participation of 87 ski instructors (age = 34.61 ±10.67) in Bosnia and Herzegovina (ATUS in Bosnia and Herzegovina). Observed variables were the prevalence of MSD measured using a modified Nordic questionnaire about injuries during the previous ski season (neck, shoulders, elbows, wrist, upper back, lower back, one or both hips, one or both knees, and ankle). Means and standard deviations for each of the variables were calculated, and differences between genders were examined using an independent sample t-test. Results. Prevalence of MSDs in ski instructors was most common in neck (13.8%), shoulders (12.6%), elbows (4.6%), wrist (9.2%), upper back (10.3%), lower back (46.0%), one or both hips (9.2%), one or both knees (29.9%), and ankle (9.2%). The results showed statistically significant differences in MSD between genders in the neck (p=.034); shoulders (p=.017); upper back (p=.027); one or both knees (p=.003) and in the ankle joint (p=.011). Conclusions. MSD’s are common in ski instructors, especially in the low back and knees of female employees. Future research or injury prevention programs would benefit these populations.

Abstract Introduction The aim of the study was to analyse the deviations of the body posture and to assess the occurrence of spine deformities. Additionally, Body Mass Index in school children was related to the trend in postural deformities for different age groups (5-8 years old, n=112; 9-11 years old, n=205; 12-14 years old, n=212) as part of the project “Spine Lab”, granted from the European Commission IPA founds, investigating the importance of public health issues. Methods Body posture was measured using Contemplas 3D software analyser, based on video image trajectory and BIA weight scale (Tanita BC 420). Overall, 17 variables were assessed, and differences were confirmed using MANOVA analysis. Results The results showed that there is a significant difference between age groups for the measured variables (F=9.27; p<0.01; η2=0.26), suggesting a moderate difference across the age span. Conclusion The study results showed that there is a negative trend of increasing Body Mass Index within the first and youngest age group. The fact is that the trend of increasing deformity of the shoulder belt has been noted, often inclining towards the formation of milder forms of kyphotic posture. Other forms of deformity that are accentuated in the survey results are the negative trend of increasing pelvic rotation and pelvis rotation which inclines towards the formation of lordotic posture for all three age groups.
