Aim: There are many tests for the young football players, but there are no studies, which analyze the correlation between postural balance of the body and the vertebral column morphology on the sagittal plane. The erector spinae muscles are completely inactive in relaxed full extension (Morrison et al. 1962) and the effects of a stimulation of the sole of the foot corresponds to a restructuring of functional relationships between the lower limbs and trunk (Gordon et al. 1995). The aim of this study was to investigated whether the shape of the vertebral column modify the center of pressure (CoP) in upright position to establish a correlation between them. Methods: Thirty-one football players (age 11±3 years, weight 40±14 kg, height 144±17 cm) were recruited. The devices used to measure the postural characteristics of the subject were: 1 - Baropodometric platform (BTS SpA, Milan, Italy) placed at 90 cm from an optical reference situated at the height of the Frankfurt plane of the examined participant, to measured the center of pressure (CoP Y); 2 - Spinal Mouse® (idiag AG, Fehraltorf, Switzerland) used by asking participants to stand symmetrically and dividing their weight equally between two feet. The Spinal Mouse® give the possibility to measure thoracic angle (ThS) and the lumbar angle (LS). Results: No significant correlations (Spearman test) were observed between: 1 - CoP Y and thoracic angle (ThS, ns); 2 - CoP Y and lumbar angle (LS, ns). Conclusions: The results show that there were no correlations between spinal curves and CoP Y. This is important data because we can use data create a preventive screening test that can help the technician to intercept dysfunctions of the joints or neurophysiologic systems.

Abstract
Aim: There are many tests for the young football players, but there are no studies, which analyze the correlation between postural balance of the body and the vertebral column morphology on the sagittal plane. The erector spinae muscles are completely inactive in relaxed full extension (Morrison et al. 1962) and the effects of a stimulation of the sole of the foot corresponds to a restructuring of functional relationships between the lower limbs and trunk (Gordon et al. 1995). The aim of this study was to investigated whether the shape of the vertebral column modify the center of pressure (CoP) in upright position to establish a correlation between them. Methods: Thirty-one football players (age 11±3 years, weight 40±14 kg, height 144±17 cm) were recruited. The devices used to measure the postural characteristics of the subject were: 1 - Baropodometric platform (BTS SpA, Milan, Italy) placed at 90 cm from an optical reference situated at the height of the Frankfurt plane of the examined participant, to measured the center of pressure (CoP Y); 2 - Spinal Mouse® (idiag AG, Fehraltorf, Switzerland) used by asking participants to stand symmetrically and dividing their weight equally between two feet.
