Background. Scoliosis is a side spinal curvature, which disturbs body statics and symmetry. Most often, it is associated with postural defects in children with a weakened, flab muscle- -ligament system. In progressive scoliosis, spine deformations cause changes in the structure and mobility of the thorax. The trunk moves in the direction of curvature convexity, affecting the arrangement of ribs and the activity ofrespiratory muscles. It results in the decrease of thorax capacity and disturbance of lung ventilation. Decrease of ventilation indicators values is proportional to the increase of spinal curvature rate. The aim of this study was to eveluate selected anthropometric and spirometric indices in low grade scoliosis affectig teenagers. Material and methods. The sample comprised a group of girls and boys aged of 13-15 years who attend correction-gymnastics classes. The study involved anthropometric and spirometric measurements. Anthropometric measurements comprised: height, weight, chest circumference, its mobility, respiratory circumference, Pignet's index and Martha's index and chest growth. Spirometric measurement comprised: spirometry, volume transfer and maximal respiratory ventilation in the subjects sitting on their heels. Results. The anthropometric measurements revealed higher values of height, weight and chest circumference while respiration, rest and expiration in boys. Chest mobility indicator was higher in girls. VC, FEV1 and FVCEX and FVCIN, values were lower than normal values. MVV, MEF50 and PEF values were significantly higher than normal values. Conclusions. Lower average FEV1 values and significantly higher MEF50 values suggest the decrease in the intercostal muscle power and correlate with the anthropometric indices of chest mobility and girth. High MVV values suggest participation of shoulder gilrdle auxiliary intercostal muscles. ABSTRACT FROM AUTHOR
