Introduction: Precision of movements responsible for maintaining balance deteriorates with age due to natural involutionary processes, thus prompting a research question whether the values of gender-related stability indicators might differ significantly among the study subjects over 60 years of age. Methods: The study group comprised 136 seniors (89 women, 47 men; aged 60–90 years). The CQ-Stab 2P 2-platform posturograph was used as the main research device, whereas the Mann–Whitney U-test was used to evaluate the gender-related differences in the average level of variables. Results: In the open-eye test, significant gender-related differences were observed with regard to the statokinesiogram’s path length in the mediolateral (ML) direction in the subjects aged 60–69 years (p=0.004), mean frequency of center of pressure (COP) displacement and number of COP displacements in the ML direction in the subjects aged 70–79 years (p=0.028, p=0.019), and mean COP displacement in the anteroposterior (AP) direction in the subjects aged 80–90 years (p=0.026). When the subjects were deprived of visual control, gender-related differences were observed with regard to the mean frequency of COP displacement, number of COP displacements in the ML direction in the subjects aged 60–69 years (p=0.045, p=0.049), and the statokinesiogram’s path length in the AP direction in the subjects aged 70–79 years (p=0.015). In the oldest age group, the differences were noted in the statokinesiogram’s path length in the AP direction (p=0.001), a sway area delimited by the COP point (p=0.003), range of AP stability (p<0.001), and range of ML stability (p=0.048). Conclusion: Gender-related differences affecting postural stability were found in the elderly. Men were characterized by a lower level of postural stability when compared with women. This highlights the need to have the gender-related differences taken into account, when developing various preventive and therapeutic programs specifically aimed at compensating certain involution-dependent deficits.

Understanding the factors and mechanisms that determine balance in seniors appears vital in terms of their self-reliance and overall safety. The study aimed to determine the relationship between the features of feet structure and the indicators of postural stability in the elderly. The study group comprised 80 seniors (41F, 39M; aged 75–85 years). CQ-ST podoscope and the CQ-Stab 2P two-platform posturograph were used as primary research tools. The data were analyzed based on Spearman’s rank correlation and forward stepwise regression. Analysis of forward stepwise regression identified the left foot length in females and Clarke’s angle of the left foot in men as significant and independent predictors of postural up to 30% of the variance of dependent variables. Longer feet provide older women with better stability, whereas in men, the lowering of the longitudinal arch results in postural deterioration. In the elderly, the left lower limb shows greater activity in the stabilizing processes in the standing position than the right one. In gerontological rehabilitation special attention should be paid to the individually tailored, gender-specific treatment, with a view to enhancing overall safety and quality of seniors’ lives.

Introduction and Aim. Down syndrome (DS) is associated with numerous developmental abnormalities, some of which cause dysfunctions of the posture and the locomotor system. The analysis of selected features of the foot structure in boys with DS versus their peers without developmental disorders is done.Materials and Methods. The podoscopic examination was performed on 30 boys with DS aged 14-15 years. A control group consisted of 30 age- and gender-matched peers without DS.Results. The feet of boys with DS are flatter compared to their healthy peers. The hallux valgus angle is not the most important feature differentiating the shape of the foot in the boys with DS and their healthy peers. In terms of the V toe setting, healthy boys had poorer results.Conclusions. Specialized therapeutic treatment in individuals with DS should involve exercises to increase the muscle strength around the foot joints, enhancing the stabilization in the joints and proprioception. Introducing orthotics and proper footwear is also important. It is also necessary to monitor the state of the foot in order to modify undertaken therapies.

An aim of this work was to determine the influence of women’s experimental training using kettlebells on selected components of physical fitness. Two groups of women, experimental (N = 20) and control (N = 20), took part in this study. In order to determine the influence of the training program developed by the present authors, participants were subjected to examinations aimed to assess the level of selected components of physical fitness (speed of hand movements, flexibility, explosive strength of lower limbs muscles, strength endurance of abdominal muscles and hip flexors, strength endurance of upper limbs muscles and the shoulder girdle, agility, the maximum oxygen uptake, the maximum and average power). Women who participated in kettlebells training showed statistically significant changes in all the examined components of physical fitness. In this group the greatest increase (84.25%) occurred in the endurance strength of upper limbs and the shoulder girdle. However, standard fitness training was more beneficial for shaping flexibility. A key element to the benefit of circuit training with kettlebells use (and additional exercises carried out in this training) is a possibility to improve comprehensive physical fitness.
