■文献中一个有趣且鲜有报道的问题是乒乓球运动员的不对称程度,其严重程度也许应该被视为受伤的风险。确定乒乓球运动员的不对称程度可以表明需要适当管理训练过程,包括培训计划中的补偿或纠正练习,尤其是最近的研究证实,训练干预可以减少运动不对称,提高表现。这项研究旨在评估女性乒乓球运动员与对照组(非运动员)相比,躯干在额叶平面上的不对称性以及四肢周长之间的差异。
■22名女性参加了这项研究。其中10名是乒乓球专业人员,平均培训经验为7±4.3年(该研究的排除标准为至少3年的培训经验)。作为一个比较组,这项研究包括12名没有参加竞技体育的女学生。使用摄影测量法使用计算机分析躯干不对称性的设备对所有受试者的身体姿势进行评估。此外,所有受试者都测量了上肢和下肢围。
■进行的研究结果表明,乒乓球运动员组中额叶平面不对称。多达六个参数——关于骨盆旋转角度,躯干倾角,下肩胛骨角度的高度和它们与脊柱的距离,以及腰部三角形,该组腰部三角形的宽度和高度以及躯干倾斜角度的差异表明不对称,但仅在上述第一个参数中与对照组存在显着差异(p≤0.05)。在几个病例中,各个组的右侧和左侧之间的周长计算差异具有统计学意义(p≤0.05)。这涉及到武器的圆周,前臂,肘部,和乒乓球运动员的膝盖。
■这项研究中进行的研究使我们能够确定在躯干的额平面以及乒乓球运动员的四肢之间不对称的发生。根据一些研究,这可能是受伤的危险因素。然而,尽管文献中对不对称造成的重要性和威胁缺乏统一的观点,看来,如果只是出于美学原因,乒乓球需要补偿性或矫正性训练,旨在发展身体结构的对称性。
UNASSIGNED: An interesting and little-reported problem in the literature is the scale of asymmetry in table
tennis players, the magnitude of which should perhaps be treated as a risk for injury. Determining the degree of asymmetry in table
tennis players can indicate the need to appropriately manage the training process, including compensatory or corrective exercises in the training program, especially since recent studies confirm that training interventions can reduce sporting asymmetries and improve performance. This study aimed to assess the amount of asymmetry in the trunk regarding the frontal plane and the difference between limb circumferences in female table
tennis players compared to the control group (non-athletes).
UNASSIGNED: Twenty-two women took part in the study. Ten of them were table
tennis professionals with an average training experience of 7 ± 4.3 years (the exclusion criterion of the study was a minimum of 3 years of training experience). As a comparison group, the study included 12 female students who did not participate in competitive sports. Body posture was assessed in all subjects using equipment for computer analysis of asymmetry in the torso using the photogrammetric method. Additionally, all the subjects had their upper and lower limb circumferences measured.
UNASSIGNED: The results of the conducted research showed asymmetry in the frontal plane in the table tennis player group. As many as six parameters-regarding the pelvic rotation angle, angle of trunk inclination, the height of the angles of the lower shoulder blades and their distance from the spine, as well as the waist triangles, difference in the width and height of the waist triangles and the angle of trunk inclination-indicated asymmetry in this group but significantly differed from the control group (p ≤ 0.05) only in the first parameter given above. The calculated differences in circumference between the right and left sides in the individual groups were statistically different in several cases (p ≤ 0.05). This concerned the circumferences of the arms, forearms, elbows, and knees of table
tennis players.
UNASSIGNED: The research carried out in this study allowed us to determine the occurrence of asymmetry in the frontal plane of the trunk and between the limbs of table tennis players. According to some studies, this may be a risk factor for injury. However, despite the lack of uniform views in the literature on the importance and threats resulting from asymmetries, it appears that, if only for aesthetic reasons, table tennis would require compensatory or corrective training aimed at developing symmetry of the body structure.
