The primary purpose of the present study was to examine differences in balance performance between the dominant and nondominant legs during dynamic balance tasks in healthy individuals with no regular exercise backgrounds. As a secondary purpose, gender differences in single-leg stance were also investigated. Material and Methods: Twenty-one men and 24 women participated in this study. Single-leg balance performance was evaluated by the Biodex Stability System SD. All subjects were tested at level 1 for 20 sec, and 1-minute rest intervals were provided among 6 trials for each leg. Results: According to the results, there was no multivariate effect of leg dominance on any stability index, indicating symmetry between limbs in terms of balance performance. Mean comparisons showed that women had significantly better balance scores than men on overall (p<0.05), antero-posterior (p<0.05), and medio-lateral (p<0.05) stability indexes. Conclusion: Functional symmetry exists between the dominant and nondominant leg in all stability indexes of balance performance of sedentary individuals. Female subjects swayed less than males on both the dominant and the nondominant leg measurements in all directions (overall, antero-posterior, and medio-lateral directions).
Stabilometry and one-leg hop test have high test-retest reliability
Scandinavian Journal of Medicine & Science in Sports, 2007
The purpose of this study was to investigate the reliability of repeated measurements and a possible learning or tiring process in single-limb stabilometry and one-leg hop test. An additional purpose was to study the correlation between different stabilometric variables. Seventy-five healthy subjects were examined twice with a median interval of 7 d, and with three consecutive measurements on each occasion. Single-limb stabilometry and one-leg hop test were found to have high reliability (ICC r = 0.68-0.83 and 0.96, respectively). The correlation between consecutive measurements was acceptable to high in stabilometry (r = 0.42-0.90, P = 0.002-P < 0.001) and high in the one-leg hop test (r = 0.91-0.97, P < 0.001). A learning process over time was observed. The correlation between the stabilometric variables was high (r = 0.73-0.95, P < 0.001).

Purpose: The aim of the present study was to investigate the effects of age, gender, height, weight, body mass index (BMI), and foot posture on single leg standing balance performance.Methods: A total of 76 healthy young asymptomatic adults were enrolled (52 females and 24 males) with an age range of 19-49 years. Age, gender, height, weight, and BMI, foot posture (Foot Posture Index), and balance (Biodex Balance Systems) were assessed. Balance assessments were performed on the dominant leg.Results: A regression analysis showed that 43.2% of the anterior- posterior (AP) stability index score explained the total variance, and the effects of height (p=0.006, B=-4.387, β=-1.974,SD=1.554), weight (p=0.001, B=0.068, β=4.550, SD=0.020), and BMI (p=0.003, B=-0.171, β=- 2.833, SD=0.056) found statistically significant. The regression analysis also revealed that 66.5% of the variance in the medial-lateral (ML) stability index score and age (p=0.026, B=0.003, β=0.173, SD=0.001) and weight (p=0...

Balance is a complex construct, affected by multiple components such as strength and co-ordination. However, whilst assessing an athlete's dynamic balance is an important part of clinical examination, there is no gold standard measure. The multiple single-leg hop-stabilization test is a functional test which may offer a method of evaluating the dynamic attributes of balance, but it needs to show adequate intra-tester reliability. The purpose of this study was to assess the intra-rater reliability of a dynamic balance test, the multiple single-leg hop-stabilization test on the dominant and non-dominant legs. Intra-rater reliability study. Fifteen active participants were tested twice with a 10-minute break between tests. The outcome measure was the multiple single-leg hop-stabilization test score, based on a clinically assessed numerical scoring system. Results were analysed using an Intraclass Correlations Coefficient (ICC2,1) and Bland-Altman plots. Regression analyses explored...
Physical Activity Review, 2019
Introduction: One from the important preconditions for optimal performance of all physical activities is a good quality of balance. Aim of Study: The study is focusing to find out the effect of pressure distribution beneath the foot on the balance and to compare the quality of balance in physically active and inactive young women. Material and Methods: Subjects of our study were two groups of healthy young women. A: physically active women (n=28; age 21.5 years; physical activity 8.8 hour/week), B: physically inactive (n=28; age 22,0 years; physical activity 1.3 hour/week). Three balance test we carried out: double-leg stance, eyes open (EO) and closed (EC) for 30 second, one-leg stance (right, left) for 10 second. Pressure walkway (FDM system, fi. Zebris) was used for data collection. Parameters: COPv: velocity of centre of pressure (mm/s), relative value of average pressure beneath the foot (%). Results: We found out that a physically active group of young women have significantly better results in all tests (p≤0.05). Both groups showed a similar tendency for significant deterioration of the results when elimination the support surface or the visual sensor in relation to the basic OE test. The differences in the distribution of pressures between the groups were significant in the M-L directions. Inactive women significantly more loaded the non-preferred leg and the rear part of the foot. Active women showed a more balanced stance in both directions, with a slight tendency to increase the loading on the front part of foot. Conclusion: It was confirmed that the group B has a partly worse characteristics of balance than physically active peers. The foot load strategy was less favourable for the group B; during EO. Only two interesting correlations were found in active women; between COPv and ratio of feet load. Remaining correlations to COPv were low.

OBJECTIVE: To identify differences in postural control among healthy individuals with different architectural foot types. DESIGN AND SETTING: We compared postural control during single-leg stance in healthy individuals with cavus, rectus, and planus foot types in our athletic training research laboratory. SUBJECTS: Thirty healthy, young adults (15 men, 15 women; age, 21.9 +/- 2.0 years; mass, 71.6 +/- 16.7 kg; height, 168.4 +/- 13.6 cm) had their feet categorized based on rearfoot and forefoot alignment measures. The right and left feet of a subject could be classified into different categories, and each foot was treated as a subject. There were 19 cavus, 23 rectus, and 18 planus feet. MEASUREMENTS: Subjects performed three 10-second trials of single-leg stance on each leg with eyes open while standing on a force platform. Dependent measures were center-of-pressure (COP) excursion area and velocity. RESULTS: Subjects with cavus feet used significantly larger COP excursion areas than...

Results The mean (SD) overall LSI was 98.8% (4.6). No significant gender or age specific differences in limb symmetry were observed. The comparison of the non-fatigued LSI with the overall LSI revealed no clinically relevant change due to muscular fatigue. Repeated measures ANOVA revealed a significant within effect on fatigue/non-fatigue condition (F (1,38) = 18.000; p < 0.001, η 2 = 0.321) on absolute single-leg hop distance. Moreover, a significant between effect on the TAS-parameter (F (1,38) = 5.928; p = 0.020, η 2 = 0.135 between: TAS ≤ 5/TAS > 5) and on gender (F (1,38) = 23.956; p < 0.001, η 2 = 0.387) could be detected. Conclusions The absolute jumping distance in the single-leg hop for distance was significantly reduced due to fatigue. No clinically relevant effect of muscular fatigue was observed on limb symmetry in our study sample. Gender and physical activity are important factors to be considered when interpreting reference values.

ASPECTS REGARDING THE INVESTIGATION OF SINGLE-LEG BALANCE IN ATHLETES
Background. Body posture develops gradually, after repeated experiences as a result of maintaining the same positions and movements of execution in the same way, in similar situations. Aims. The study aims to highlight the views of former performer athletes in tests middle distance running, on the relationship between training and body posture. Methods. Were subjected to a questioning of 32 former middle distance runners aged 19-23 years who have renounced at sport for 1-3 years. We applied a questionnaire with 15 items with multiple pre-coded answers. Results. Applying the mirror test required the subjects to objective consideration of the 6 items. 167 cases were identified indicating a correct posture and only 25 that does not comply with proper posture. The correlation coefficient (r) Pearson is 0.72 significance level 0.01, which indicates that there is a strong relationship between body posture and position in the frontal plane examined. When examining the side, subjects were identified after examining 91 nominations for the correct positions in various segments and 69 situations that do not correspond to the correct posture. The relationship between body posture and body position is considered strong side r = 0.79 and p = 0.01 significance level. Conclusions. The results obtained allow us to continue our research and use athletics as a means to favoring factor maintaining normal posture and obtain the sports performance.
