Content available remote Postural variables in girls practicing sport gymnastics
Study aim: To assess body posture variables in girls practicing sport gymnastics vs. their untrained mates.Material and methods: Two groups of girls aged 7 - 11 years were studied: 48 young female gymnasts (Group SG) and 54 untrained girls (Group C) of comparable age, body height and BMI. The gymnast girls had 3 - 7 training sessions a week, their training experience ranging 1 - 5 years. Body posture was assessed by photogrammetry.Results: Shoulder blades and pelvis were significantly (p<0.05) more symmetrical in gymnast girls than in the control group and their spine was better shaped in the youngest gymnasts (p<0.01). Gymnast girls were significantly (p<0.01) superior to their untrained mates in overall posture rating, Lumbar lordosis was less expressed (p<0.05) in gymnast girls aged 7 - 10 years than in the control ones.Conclusions: Sport gymnastics practiced at young age may affect posturogenesis bringing about body symmetrisation and shaping spine curvatures, especially lumbar lordosis.
Content available remote Postural variables in girls practicing volleyball
Study aim: To assess body posture of young female volleyball players in relation to their untrained mates.Material and methods: A group of 42 volleyball players and another of 43 untrained girls, all aged 13 - 16 years were studied with respect to their body posture indices by using computer posturography. Spinal angles and curvatures were measured, and asymmetry and body posture type were assessed. Body height and mass, BMI and body fat content (by bioimpedance technique) were determined.Results: As compared with untrained girls, the volleyball players were more slender, the positions of shoulders and pelvis being more symmetrical, and shoulder blades and waist triangles were more asymmetrical. Volleyball players were predominantly kyphotic, their lumbar lordosis was flattened and head protruded, especially in those having longer training experience.Conclusions: The observed asymmetries brought about by unilateral training loads and progressing thoracic kyphosis call for applying corrective and/or yoga exercises to adolescent female volleyball players.
Study aim: martial arts can be traced back thousands of years. Karate is one of the most common martial arts, and both children and adults practice it. The aim of the study was to evaluate selected body posture parameters in children aged 7–10 years who regularly practice karate. Material and method: the study population (Group I) consisted of 50 children aged 7–10 years, mean age 8.1 ± 1.5 years, who had been practicing karate more than two years. The control group consisted of 50 children of the same age (Group II). Body posture was assessed with photogrammetric method based on the phenomenon of the projective moiré pattern, using CQ Elektronik equipment. Results: on the basis of analysis of the inclination of the thoracolumbar section of the spine in both the study population and the control group, a statistically significant difference was found. Analysis revealed a statistically significant difference between the SIT parameter measurements of the two groups (p < 0.05). There is a similar difference regarding the measurements of depth of thoracic kyphosis and depth of lumbar lordosis (p < 0.001 and p < 0.05, respectively). Analysis also revealed a statistically significant difference between the mean shoulder line inclination angle parameter measurements for the two groups of children (p < 0.01). Conclusion: karate training children had a significant deepening of physiological thoracic kyphosis and lumbar lordosis. The body posture in karate training children is characterised by a greater angle of thoracolumbar region and a smaller shoulder asymmetry.
Content available remote The influence of elongation exercises on the anterior-posterior spine curvatures
Introduction: Elongation exercises are designed to reduce existing pathological or increased physiological curvatures of the spine. The aim of the study was to evaluate the changes occurring in the parameters describing the anterior-posterior spinal curvatures during the performance of symmetric elongation exercises. Material and methods: The study included 150 children aged 7-10 years: 82 girls and 68 boys. It was performed in June 2012, following prior parental and the subjects’ consent. The study design was approved by the Bioethical Committee of the Medical Faculty of Rzeszow University (number 05/07/2012). In each subject, an examination of the body posture was performed twice - first in a relaxed position and second during an elongation exercise. The Wilcoxon pair sequence test was used for statistical analysis. Results: The lumbosacral angle was significantly higher during the performance of an elongation exercise (p < 0.001), and so was the thoracolumbar angle (p < 0.001). The angle of the upper thoracic spine (p < 0.01) was significantly reduced. In the case of parameters describing thoracic kyphosis, a significant increase was observed both for the thoracic kyphosis angle (p < 0.01) and the depth of this part of the spine. As for the parameters describing lumbar lordosis, both the lordosis angle and its depth were significantly reduced (p < 0.001 and p < 0.001). Conclusions: 1. Elongation exercises reduce the depth of lumbar lordosis. 2. During elongation exercises thoracic kyphosis becomes deeper
Content available remote Body posture of young female basketball players
Study aim: To assess body posture and somatic parameters in young females practicing basketball in comparison with their non-training peers and to state whether there is a relationship between the quality of one's posture and the length and frequency of training.Material and methods: The study included 32 young female basketball players aged 13-15 years old. The period of basketball practice was 3-4 years for the group aged 13-14 years; the frequency of practice was 3-7 times per week. In the case of the group of 15-year-olds, it was 4-5 years, 4-7 times a week, respectively. The control group consisted of 37 young female subjects in the same age brackets that did not participate in any directed physical activity. Body height was measured with the use of a height meter at medical scales, whereas body mass, fat mass, and total body water mass were defined with the use of Tanita electronic scale. A specialist device using the projection Moiré method (MORA, CQElektronik System, Poland) was used to assess one's body posture.Results: Body height and water mass were significantly different in the younger group. However, the parameters of body posture differed significantly only in the group of 15-year-olds. The following have been observed: much greater asymmetries in pelvic placement in the transverse plane (p<0.05), significantly greater asymmetries of shoulder blades in relation to the transverse plane (p<0.01), as well as significantly smaller thoracic kyphosis angle (p<0.05) in female basketball players in comparison with the placement of the above parameters in their non-training peers. Moreover, correlations between the frequency of basketball practice and the deflection of the line of spinous processes, torso inclination angle, placement of shoulder blades in the transverse plane and towards the spine, kyphosis angle, and a synthetic index of body posture (i.e. postural symmetry) were noted.Conclusions: Training basketball may lead to increased occurrence of asymmetry of one's body posture.
