BACKGROUND: 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). METHODS: 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. RESULTS: 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. CONCLUSIONS: 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.

Koncept minimalistické (barefoot) obuvi představuje způsob obouvání, který si klade za cíl přiblížit chůzi v obuvi podmínkám chůze naboso. Minimalistická obuv se obvykle vyznačuje tvarem respektujícím morfologii nohy, nízkou hmotností, absencí podpůrných konstrukčních prvků a tenkou, plochou a všemi směry ohebnou podešví. O konceptu minimalistické obuvi se často tvrdí, že umožňuje přirozenější způsob chůze a má pozitivní vliv nejenom na tvar a funkci nohy, nýbrž na celý pohybový aparát člověka. Tento článek si klade za cíl shrnout dosavadní poznatky o vlivu minimalistické obuvi na biomechaniku chůze dospělého člověka, a tím pomoci osvětlit, zdali lze výše uvedená tvrzení podpořit vědeckými důkazy.
The concept of minimalist footwear is a way of wearing shoes that aims to bring walking in shoes closer to barefoot conditions. Minimalist footwear is usually low-weight footwear shaped to respect the morphology of the foot, with the absence of supporting structural elements, and a thin, flat, and flexible sole. It is supposed to allow a more natural way of walking and positively affect the shape and function of the foot and the whole human body. Several studies deal with its effect on the human musculoskeletal system, but many areas still require further research. This paper aims to summarize the current knowledge on the influence of minimalist footwear on gait the biomechanics of adults.
