Effects of hatha yoga exercises on spine flexibility in women over 50 years old

[Purpose] The aim of this study was to access the flexibility of the spine in women practicing yoga as a part of the University for Health project. [Subjects and Methods] The study included 56 women ranging in age between 50-79 and attending 90 minutes hatha yoga sessions once a week. The measurements were performed twiceat the beginning of the project and after its completion, i.e., after 20 weeks of classes. The range of spine mobility in three planes was measured using a Rippstein plurimeter. The range of motion in the sagittal and frontal planes was measured in a standing position with the feet hip-width apart. The torsional range of motion of the subjects was measured with the trunk bent at a right angle and the legs apart. The flexibility ranges of the spine and hamstrings were also measured by the toe-touch test in a standing position. [Results] This study showed that the applied yoga exercises increased spinal mobility and flexibility of the hamstring muscles regardless of age. [Conclusion] Yoga exercises should be recommended to the elderly to make their muscles more flexible and to increase the range of motion in the joints, which is particularly important for improving their life quality.
