AIM The study evaluated the variation in the flexibility of the spinal column after an acute respiratory training session based on isocapnic hyperpnea in a group of professional women soccer players. METHODS Ten professional women soccer players took part in this study (age: 21±4 years (mean±SD), height: 166±5 cm, weight: 62±6 kg, BMI: 22±2 kg, and with 12±5 years of training). The following devices were used: - The Spirotiger® (ST), for respiratory training in isocapnic hyperpnea (MVM, Italy), which measures the total volume of air breathed by the athlete; - The SpinalMouse® (SM), for morphological evaluation of the spinal column and of its joint mobility, which provides a number of parameters as listed in the following: 1) Chest segment (ThSp): the angle between the first ThSp1 and the last thoracic vertebrae ThSp12; 2) Lombar segment (Lsp): the angle between the last thoracic ThSp12 and the first sacral vertebrae S1; 3) Sacral angle (Sac/Hip): the angle created by the contour of the sacral segment with respect to the plumb line; 4) Inclination (Inc): the connection between ThSP1 and S1 defines the inclination line. The angle created between this line and the plumb line is the Inc angle. 5) Length of segment ThSp1 – S1 (Length): the length of the back measured from C7 to S1 expressed in millimetres (value corresponding to the trajectory of the instrument). To avoid biased results between the conditions with (W) and without (WO) ST the counter balance design was used. RESULTS Statistically significant differences (Wilcoxon test, WO vs W) were observed both in the ThSp (P<0,05, -16%) and in the length of the extended spinal column (P<0,05, -3%), which were found to be lower after the acute respiratory training session. DISCUSSION/CONCLUSION The acute application of respiratory training shows a reduction in spinal column flexibility, highlighting how training is a process to be carried out chronically.

METHODS Ten professional women soccer players took part in this study (age: 21±4 years (mean±SD), height: 166±5 cm, weight: 62±6 kg, BMI: 22±2 kg, and with 12±5 years of training). The following devices were used: - The Spirotiger® (ST), for respiratory training in isocapnic hyperpnea (MVM, Italy), which measures the total volume of air breathed by the athlete; - The SpinalMouse® (SM), for morphological evaluation of the spinal column and of its joint mobility, which provides a number of parameters as listed in the following: 1) Chest segment (ThSp): the angle between the first ThSp1 and the last thoracic vertebrae ThSp12; 2) Lombar segment (Lsp): the angle between the last thoracic ThSp12 and the first sacral vertebrae S1; 3) Sacral angle (Sac/Hip): the angle created by the contour of the sacral segment with respect to the plumb line; 4) Inclination (Inc): the connection between ThSP1 and S1 defines the inclination line.
