Background: ‪The overall purpose of this study is to define differences in the symmetry of stabilizing function of lower limbs in geriatric women compared to younger females. Material and methods: ‪The study evaluated 30 female seniors (aged 82.9 ±6.1), 39 female university students (aged 23.3 ±0.4) and 33 girls (aged 7.4 ±0.3). Stability was evaluated using a stabilographic platform CQ Stab (Electronic System), with the subject standing with eyes open. Anova Kruskal-Wallis test and Wilcoxon test were used for the analysis. Results: T‪he average percentage differences in limb loading (LLA) show a slight, not exceeding 2.5% asymmetry in the distribution of body weight. There was no statistically significant intergroup variation in this range. In extreme age groups asymmetry of indicators of the movement of the center of foot pressure (SPML MVML) was observed. Conclusions: ‪The shift in asymmetry of mass distribution towards the right lower limb (non-predominant) observed in the elderly women might point to tendencies for greater involvement of the limb which is less affected by the ageing processes. This, however, needs further investigation. The asymmetry of activity in the lower limbs in the stabilization function in elderly people needs to be offset through exercises improving somatosensory mechanisms of balance control.

The study aim was to evaluate the effect of a 6-week modified workout routine using the modified circuit weight method on selected anthropometric measures, components of physical fitness and physiological indices in competitive basketball players. The study involved 30 basketball players (mean age: 23.4 ±1.8 years). Modified circuit weight method sessions were repeated 3 times a week. Each training session was subdivided into 3 circuits: strength conditioning, exercises to enhance functional fitness and a circuit of sport-specific exercises. Statistically significant differences in values of circumferences and skinfolds were found between pre-test and post-test values, with no statistically significant changes in body mass and total body water. A statistically significant improvement was observed in motor ability tests, except for the barbell bench press test (p = 0.096). Statistically significant differences were also found in the values of physiological indices. The 6-week training using modified circuit weight method induced positive adaptations in most of the diagnosed anthropometric indicators, components of physical fitness and physiological parameters. This supports the notion of the comprehensive effect of such training on human body and suggests its usefulness for both athletes involved in specific sports and in health-oriented training of amateur athletes.

Background: The aim of the study was to determine the changes that occur during a back handspring performed by artistic gymnastics competitors on the basis of selected biomechanical quantities. Material/Methods: The case study included five masterclass artistic gymnastics competitors. The activities were recorded at the frequency of 120 [Hz]. Using the SkillSpector computer software, selected biomechanical variables of the back handspring technique were analyzed. The coefficient of variation was used to evaluate the variability of movement, which, in turn, was used to describe the repeatability of the back handspring technique. Results: Kinematic analysis of the back handspring carried out with the recorded video material enables the qualitative evaluation of the repeatability of the sports technique. The position of the center of mass on the vertical axis determined at borderline points of phases in the back handspring technique was the quantity of highest repeatability. The lowest repeatability was observed in the absolute and relative (movement rhythm) durations of particular phases. Conclusions: It is possible to master the back handspring while maintaining full repeatability of some biomechanical quantities characterizing the movement technique. The assessment of movement repeatability in gymnastics requires further research, with the simultaneous analysis of various biomechanical quantities and a determination of the best methods of comparison.
