| Summary: | The objective of this study was to evaluate the frequency of functional kyphosis and lumbar kyphosis in adolescent paddlers. A total of 140 paddlers (mean age: 13,67 ± 0,61 years) participated in this study. The sagittal spinal curvatures (thoracic and lumbar curves) in relaxed standing and in maximal trunk flexion with knees extended (sit-and-reach test) were evaluated with an inclinometer. The analysis of angular values with respect to the normality references showed that 63% of athletes with normal thoracic curve in standing, while in maximal trunk flexion there were many athletes (91.2%) with a moderate or slight kyphotic posture. With respect to lumbar curve, 68.5% of the subjects had normal values in standing, while 83.9% showed lumbar kyphotic postures in maximal trunk flexion. In conclusion, there was a high percentage of paddlers with normal angular values in relaxed standing, although when maximal trunk flexion with knees extended was performed there was a significant increase of kyphotic postures in both thoracic and lumbar curves. For this reason, the evaluation of sagittal spinal curvatures of paddlers is an important variable to include in training planning. |
