Abstract
Background/Objectives: The purpose of this study was to assess the body posture of kickboxing players. Methods: The study group included people training as kickboxers who actively participated in the training camp of the broad national junior team in the K1 and low-kick kickboxing leagues. The control group consisted of non-training people. The age of the study group ranged from 15 to 23 years. The ages of the control group participants varied from 14 to 20 years. A body posture test was performed by using the Moiré method, in accordance with the guidelines of the manufacturer of the Moiré 4G device. Results: The body posture test performed using the Moiré method showed statistically significant differences between the kickboxing training group and the control group. The parameters that showed statistically significant differences included the size of lordosis (KLL) and the depth of lordosis (GLL) in the lumbar spine. Higher values were observed in the kickboxing training group compared to the control group. There was no statistically significant difference between the kickboxing group and the control group in other parameters. Conclusions: The asymmetrical and flexed posture required during kickboxing training did not negatively influence the competitors' spinal curvatures. Kickboxers had increased lumbar lordosis, which may be related to the specificity of the given discipline (stretching of the hamstrings and specific movements). This is a beneficial phenomenon that may reduce the risk of lower back pain. Kickboxing training did not affect the asymmetry of body posture in the sagittal plane.
