Purpose. The purpose of this study was to assess the influence of hatha yoga exercises on the shaping of the antero-posterior spinal curvature in first-year students of the University of Physical Education in Katowice who participated in hatha yoga classes. Methods. 72 women and 46 men took part in the study. Hatha yoga classes were held once a week for 90 minutes over a period of 15 weeks. Measurements of the subjects' spines were performed twice, first before the start of the classes and then after all the classes were finished. The students were divided into three groups, the first composed of all the participants in the study, the second of students whom attended the yoga classes and practiced hatha yoga in their free time, whereas the third group was composed of students for whom hatha yoga was their only form of physical exercise. The inclination of the anteroposterior curvature of the spine, i.e. the thoracic kyphosis and lumbar lordosis angles, were measured with a Rippstein plurimeter. Results. The results found that after 15 weeks of yoga, a decrease in the thoracic kyphosis angle (ThKA) and lumbar lordosis angle (LLA) occurred in most of the subjects. Differences between the values of these angles before/after yoga were statistically significant in women (p < 0.001), whereas in men, only a decrease of the thoracic kyphosis angle was statistically significant (p < 0.001). After completing the hatha yoga classes, the majority of students (50-62%) were found to have correct angular values of the thoracic kyphosis and lumbar lordosis when compared to the measurements taken before the start of classes (40-45%). Conclusion. An assessment on the shaping of the anteroposterior curvature of the spine finds that hatha yoga exercises have a positive impact on one's body posture in the sagittal plane.

Specific loads on the spine and the very young age at which acrobatic gymnastics training is undertaken require monitoring the shape of the spine curvatures in gymnasts to detect possible postural abnormalities. The aim of this descriptive study was to assess and compare the shape of the spine in the sagittal plane in acrobatic gymnasts of both sexes and their associations with demographic and somatic variables. The study group included 159 acrobatic gymnasts aged 12-19 (106 females and 53 males) from 16 European countries. The study was designed as a survey and measurements of somatic variables and the angles of inclination (using the Baseline Bubble inclinometer) at four topographic points of the spine: S1, L5/S1, Th12/L1, C7/Th1. Based on the angles of spinal inclination, the sizes of the sacral slope (SS), lumbar lordosis (LL), and thoracic kyphosis (TK) were calculated. Body posture was assessed based on Wolański’s modified typology. The angles of SS and LL were significantly higher in females, and TK did not differ between sexes. Training experience positively correlated only with the size of the SS in both sexes. Age and somatic variables were significantly correlated with the size of the sagittal curvatures, mainly in females. The majority of gymnasts had a normal angle of SS and TK and a flattened LL. The equivalent and lordotic types of body posture were more frequent in females, and the kyphotic type in males. The incorrect body posture was noted in 19.8% of females and 43.4% of males. We concluded that acrobatic gymnasts are not at risk of increasing the size of spinal curvatures in the sagittal plane, but males show a tendency toward flattened LL and kyphotic type of body posture.

Celem pracy jest charakterystyka krzywizn przednio-tylnych kręgosłupa w wybranym okresie rozwoju dziewcząt na tle ich rozwoju somatycznego. Hipoteza badawcza: krzywizny przednio-tylne kręgosłupa kształtują się ę miarę rozwoju osobniczego, a zmiany wartości poszczególnych cech zalezne są od wieku badanych. Materiał badawczy: badaniami objęto 667 dziewcząt z Plocka z wybranych losowo przedszkoli i szkół, w wieku od 6 do 16 lat. Metoda badawcza: analizy ukształtowania kręgosłupa w płaszczyźnie strzałkowej dokonano metodą fotogrametryczną wykorzystującą efekt mory. Określono wielkości następujacych parametrów: długość całkowitą kręgosłupa, udzial długości całkowitej kręgosłupa w wysokśsci ciała, długość lordozy lędźwiowej, udział długości lordozy lędźwiowej w długości całkowitej kręgosłupa, głębokość lordozy lędźwiowej, długość kifozy piersiowej, udział kifozy piersiowej w długości całkowitej kręgosłupa, głębokość kifozy piersiowej, kąt nachylenia odcinka lędźwiowo-krzyżowego, odcinka piersiowo-lędźwiowego i odcinka piersiowego górnego. Wnioski: 1. Kształtowanie się kręgosłupa w płaszczyźnie strzałkowej charakteryzuje się pewną autonomią w odniesieniu do rozwoju somatycznego. 2. Długość całkowita kręgosłupa wykazuje tendencję do stałego zmniejszania swojego udziału w stosunku do całkowitej wysokości ciała. 3. Krzywizną intensywnie zwiększającą swoją długość jest odcinek lędźwiowy kręgosłupa.

The aim of the paper is to characterise the anterio-posterior spinal curvatures in a chosen development period in girls contrasted with their somatic development. Research hypothesis: the anterio-posterior spinal curvatures are formed along with development, and changes of the values of particular characteristics depend on the age of the examined. Material: the research was carried out in a group of 667 girls, aged from 6 to 16 from Płock who were randomly chosen from kindergartens and schools. Method: the analysis of the spinal curvatures in the sagittal plane was carried out by means of the photogrammetric method, which employs the Moira effect. The following parameters were determined: the total length of the spine, the percentage of the total length of the spine in body height, the length of lumbar lordosis, the percentage of the length of lumbar lordosis in the total length of the spine, the depth of lumbar lordosis, the length of thoracic kyphosis, the percentage of the length of thoracic kyphosis in the total length of the spine, the depth of thoracic kyphosis, the inclination angle of the lumbo-sacral section of the spine, the inclination angle of the thoraco-lumbar section of the spine, the inclination angle of the upper thoracic section of the spine. Conclusions: 1. Spinal curvatures in the sagittal plane are characterised by certain autonomy in relation to somatic development. 2. The total length of the spine shows a tendency toward decreasing of its percentage in body height. 3. The lumbar section of the spine is a curvature which intensively increases its length.
