Study aim: The aim of this study was to evaluate the influence of hatha yoga practices on the shaping of the anteroposterior (AP) spinal curvatures in students of the University of the Third Age, who participated in hatha yoga classes. Material and methods: 20 women and 5 men took part in the study. Hatha yoga classes were held once a week for 90 minutes over a period of 8 months along with additional exercises including basic positions of hatha yoga in home conditions 1-2 times a week for about 30 minutes. The inclination of the AP curvatures of the spine was measured twice, before and after the end of the classes. A Rippstein plurimeter was used for the measurements. R esults: Measurements of the angle of thoracic kyphosis before starting the series of hatha yoga classes and after finishing them showed a decrease in thoracic curvature in female (p < 0.01). In case of the angle of lumbar lordosis, a reduction in this curvature as a result of yoga techniques has been observed in women (p < 0.01) too. Amounts of AP curvatures of the spine, measured after completing the series of hatha yoga classes, fluctuated around correct values better than before taking them up. Conclusion: This study has shown that yoga training leads to an improvement in the habitual body posture in case of aggravating (excessive) AP curvatures of the spine.

Introduction: The study is 10 years’ observation of anterior-posterior spinal curvatures in the same group of children and youths.The first objective is to show rules and regularities in changes of posture in boys and girls in the period of their lives under the observation. The other objective is to put forward a suggested procedure for posture assessment based on the presented measurement method of the angle of lumbar lordosis and thoracic kyphosis using a simple protractor, where the obtained angle values were to be used as qualification of faulty posture. Material and methods: A group of 100 children and youths aged 4-16 years, including 58 girls and 42 boys, examined initially in 1997 and then re-examined after 10 years, that is in 2007 (at the age of 14-26), made up the test material. Results: In Examination II, the incidence of a round back in girls in all age groups decreased while in boys it increased. The changes were statistically significant. Conclusions: Over the 10 years’ period in the children and youths that constituted the test material different changes in postures were found in the male group and in the female group. In girls after the puberty period, transitions in posture towards decreasing thoracic kyphosis and increasing lumbar lordosis were found, while in boys, posture changes in the opposite direction, i.e. increasing thoracic kyphosis and decreasing lumbar lordosis, were observed. Child’s body posture assessment carried out with the use of simple measurement instruments following the examination method suggested in this paper i.e. measuring thoracic kyphosis and lumbar lordosis angle values appears to be a reliable method of body posture qualification in screening tests and monitoring results of faulty posture treatment
