Sport climbing has become very popular in the last two decades. More and more people are getting into recreational, as well as competitive climbing. The aim of this Master’s thesis was to gain information about the posture of sport climbers and to study the influence of corrective exercise on their posture. Since posture changes can lead to various health problems and injuries, our goal was to make sport climbers aware of the importance of stretching and strengthening specific muscle groups through corrective exercise. We measured changes that occur in the thoracic spine during kyphosis, and the mobility of pectoral muscles, hip flexors and hamstrings (Förster et al., 2009). Roundback is caused by a reduced pelvic tilt, which results in a loss of lumbar lordosis and rounded shoulders. Preventive and corrective measures can improve abnormal posture (Šarabon et al., 2015). We used the SpinalMouse® device to analyse spinal posture and mobility. By sliding the device along the spine, the built-in accelerometers take measurements, which are then used to generate a graphical display of the spine and calculate its inclinations. In order to assess muscle flexibility, we used the Thomas test, the iliopsoas flexibility test, the pectoralis major flexibility test and the hamstring flexibility test. The measurements were taken both before and after corrective exercise. The climbers performed corrective exercise twice a week for eight weeks. There were no statistically significant changes or improvements of kyphosis after the corrective exercise. However, improved mobility of the left pectoralis major and the left hamstring were attributed to corrective exercise. Contrary to previous studies, there was no correlation between corrective exercise and the angle of thoracic kyphosis.
