    Opis:
    The aim of the study was to compare the values of selected stability indices registered in the trials in standing with eyes open and without visual control, and in handstand in athletes practicing artistic gymnastics at the highest level of advancement. Methods: The study included 20 athletes practicing artistic gymnastics. The research tool was posturograph CQ-Stab 2P. The results obtained in individual trials were compared using Friedman repeated measures analysis of variance by ranks and then subjected to Dunn post-hoc test with Bonferroni adjustment. Results: Statistically significant differences in the values of stability indices recorded in individual samples were found. Exceptions are the results obtained in the trials with eyes open and without visual control with regard to the size of the surface area delineated by the COP ( p = 0.173) and the frequency of corrective reactions ( p = 0.464), as well as the length of the statokinesiogram path in the mediolateral direction ( p = 0.342), mean velocity of COP movement in the mediolateral direction ( p = 0.246), maximal amplitude of the COP in the mediolateral direction ( p = 0.342) and number of COP displacements in the mediolateral direction ( p = 0.246). Conclusions: In seniors, disabling visual control during free standing as well as adopting a handstand position result in deterioration of the stability indices, which is a resultant of the COP displacement in both directions as well as in the anteroposterior direction. Lack of differences in the values of stability indices in the mediolateral direction suggest that in a free standing position, seniors practicing artistic gymnastics control the movement of the center of foot pressure in the mediolateral direction and eye control is not important for the stability of the body in the frontal plane.

    Opis:
    Purpose: The aim of this study was to compare and analyse of relationships between stability indices registered in two positions: standing and handstand in athletes practicing gymnastics at various levels of advancement. Methods: The study included 46 athletes practicing gymnastics. The research tool was posturograph CQ-Stab 2P. Results: In both standing position and handstand in the seniors there were statistically significantly lower values of such indicators as: sway area delimited by the center of pressure ( p = 0.004, p = 0.014), mean amplitude of COP ( p = 0.021, p = 0.017), mean displacement of the center of feet/hands pressure in medio-lateral direction ( p = 0.011, p = 0.003) and maximal displacement of the center of feet/hands pressure in mediolateral direction ( p = 0.036, p = 0.036). In the standing position, seniors also had statistically significantly lower values of the statokinesiogram path length, both total ( p = 0.000) as well as in anteroposterior ( p = 0.001) and mediolateral ( p = 0.002) directions. In the seniors group there were statistically significant correlations between variables obtained in standing position and handstand. Conclusions: The level of sport advancement significantly differentiates the stability of a body in standing position and handstand. The seniors practicing gymnastics, compared to juniors, are characterized by a better ability to control the position of the body in both positions. The lack of relationships between stability indices registered in standing and handstand in juniors suggests that the analysis of the values of stability indices obtained in a standing position does not provide the possibility of predicting the ability to maintain balance in the handstand during the recruitment of candidates for gymnastics.

    Opis:
    This study aimed to determine the characteristic features of handstand posture control associated with a high level of ability among male gymnasts. Methods: 8 acrobatic gymnasts (4 more and 4 less experienced) participated in the study. They performed a 10-second handstand five times with each hand positioned on one AccuSway (AMTI) force platform and the other hand on the second. Body sway changes were recorded in time series: centre of pressure (COP) and components of the ground reaction force (GRF) (vertical, medial-lateral and anterior-posterior). The COP amplitude and average of GRF components, the index of frequency (by Fast Fourier Transform) for the right and left hand were calculated. Results: More experienced gymnasts performing a handstand concentrate mainly on minimizing anterior-posterior body sway with minimum medial-lateral body sway. Less experienced gymnasts’ pressure exerted on a surface by the hands is irregular in a medial-lateral direction. More experienced gymnasts control body position in the handstand and show less variation of body sway compared to less experienced gymnasts. More experienced gymnasts revealed lower frequency of body sway in the handstand compared to less experienced gymnasts. Conclusion: The stabilometric profile of more experienced gymnasts means the better posture control in handstand. The minimizing of body sway is compensated by exerting more force on a floor surface and the less experienced athletes cannot do that even after several years of training. The gymnasts of both groups, during standing on their hands, put more load on the right hand.
