Maximal strength, muscular endurance, maximal aerobic power, and anaerobic capabilities, power are needed to have victory for wrestlers in a wrestling competition.The aim of the study is to investigate the effect of acute muscular fatigue on static and dynamic balance performances in elite wrestlers. Ten elite male wrestlers (25 ± 2.3 years, 181 ± 6.5 cm, 84 ± 4.2 kg) participated in the study voluntarily. Participants were undertaken dynamic and static balance test before fatigue exercise (in Cybex) and immediately after fatigue exercise, theywere undertaken dynamic and static balance test again. SPSS packet program was used to evaluate the data. There were no statistically significant differences in static and dynamic balance before and after fatigue. The results show that wrestlers’ balance is not affected by muscular fatigue, so there is no need for balance exercise after fatigue at least according to this study.

Research background. Aging constantly manifests itself not only in physiological changes, but also in cognitive ones. Exercise programs for elderly have been created aiming at avoiding risk of falling, but there is little known about changes in cognitive functions under the effect of exercise. The aim was to evaluate the effect of water-based and land-based exercises on balance and cognitive functions in elderly women and men. Methods. The dynamic balance of study participants (n = 32) was evaluated using Timed Up & Go Test, the static balance was evaluated with a 4-position Static Balance Test and the cognitive functions were evaluated with Six-Item Cognitive Impairment Test, the Cognitive Failures Questionnaire and the Trail Making Test. The participants were randomly divided in two groups: water exercise and land-based exercise. Results. After 8 weeks of exercise in water and on land, static and dynamic balance and cognitive functions improved in both groups (p < 0.05), no statistically signifcant difference was found between the groups except for the trail making test, which was performed more quickly by subjects who attended exercise in water. After the exercise program, the men’s dynamic and static balance (while standing in the tandem position) were better than women’s, but women’s standing on one leg position was better than that of men’s (p < 0.05). Conclusion. There were no statistically signifcant differences in cognitive function between men and women after intervention. After both exercise programs, dynamic and static balance (in the tandem position) in men were better (p < 0.05) than those in women, standing on one leg but women’s position was statistically signifcantly better than that of men’s.Keywords: exercise program in water and land-based, static and dynamic balance, cognitive functions.

Balance disorders have a high prevalence among elderly people in developed countries, and falls resulting from balance disorders involve high healthcare costs. Therefore, tools and indicators are necessary to assess the response to treatments. Therefore, the aim of this study is to detect relevant changes through minimal detectable change (MDC) values in patients with balance disorders, specifically with vertigo. A test-retest of a static and dynamic balance test was conducted on 34 healthy young volunteer subjects using a portable stabilometric platform. Afterwards, in order to show the MDC applicability, eight patients diagnosed with balance disorders characterized by vertigo of vestibular origin performed the balance test before and after a treatment, contrasting the results with the assessment by a specialist physician. The balance test consisted of four tasks from the Romberg test for static balance control, assessing dynamic postural balance through the limits of stability (LOS). The results obtained in the test-retest show the reproducibility of the system as being similar to or better than those found in the literature. Regarding the static balance variables with the lowest MDC value, we highlight the average velocity of the center of pressure (COP) in all tasks and the root mean square (RMS), the area, and the mediolateral displacement in soft surface, with eyes closed. In LOS, all COP limits and the average speed of the COP and RMS were highlighted. Of the eight patients assessed, an agreement between the specialist physician and the balance test results exists in six of them, and for two of the patients, the specialist physician reported no progression, whereas the balance test showed worsening. Patients showed changes that exceeded the MDC values, and these changes were correlated with the results reported by the specialist physician. We conclude that (at least for these eight patients) certain variables were sufficiently sensitive to detect changes linked to balance progression. This is intended to improve decision making and individualized patient monitoring.

Context:Proper functioning of the intrinsic foot musculature (IFM) is essential in maintaining the integrity of the medial longitudinal arch (MLA). Improper functioning of the IFM leads to excessive pronation of the foot, which has been linked to various pathologies. Therefore, training the IFM to avoid excessive pronation may help prevent some of these pathologies; however, it is not clear how to train these muscles optimally.Objective:To investigate the effects of 2 different types of IFM training on the height of the MLA and static- and dynamic-balance task performance.Design:Randomized controlled trial, repeated-measures mixed-model design.Setting:University biomechanics laboratory for testing and a home-based training program.Participants:24 healthy, university-age volunteers (3 groups of 8) with no history of major lower limb pathology or balance impairment.Interventions:One experimental group performed 4 wk of the short-foot exercise (SFE) and the other performed 4 wk of the towel-curl exercise (TCE). Participants were asked to perform 100 repetitions of their exercise per day.Main Outcome Measures:Navicular height during weight bearing, the total range of movement of the center of pressure (COP) in the mediolateral (ML) direction for a static-balance test and a dynamic-balance test.Results:There were no differences in the navicular height or static-balance tests. For the dynamic-balance test, all groups decreased the ML COP movement on the dominant limb by a small amount (~5 mm); however, the SFE group was able to decrease COP movement much more than the TCE group in the nondominant limb.Conclusions:The SFE appeared to train the IFM more effectively than the TCE; however, there were differing results between the dominant and nondominant legs. These imbalances need to be taken into consideration by clinicians.

Background: Balance deficits are usually related to medial-lateral instability. BMI could be an important factor to consider as; excess body mass or increased accumulation of adipose tissue can directly impact the postural stability which in return impacts balance. Purpose of the study: To find the correlation between BMI and Balance. Method: Sample consisted of 149 students, out of which 100 (67%) were males and 49 (33%) were females. BMI was calculated and was categorized into groups. Bilateral limb length was measured for normalising the data. Static balance was measured by performing blinded stork test and dynamic balance by performing Y- balance test. Data was analysed using Pearson’s correlation test. Result: There was significant correlation between BMI and static balance of left leg (r=0.713, 95% CI 0.623, 0.784, p=0.01) but on comparison, there was no significant correlation between BMI and static balance of right leg (r=0.0458, 95% CI -0.11, -0.205, p=0.58). It was found that there was no significant correlation between BMI and Left Anterior (r= -0.134, 95% CI -0.289, -0.0274, p= 0.103), Left Posterolateral (r=-0.0775, 95% CI -0.235, 0.0843, p=0.347), Left Posteromedial (r=-0.0903, 95% CI -0.248, -0.0715, p=0.273) respectively. Also, it was found that there was no significant correlation between BMI and Right Anterior (r=-0.236, 95% CI -0.382, -0.0778, p=0.00381), Right Posterolateral (r=-0.193, 95% CI -0.343,-0.0334, p=0.0183), Right Posteromedial (r=-0.126, 95% CI -0.281, -0.0354, p=0.125) respectively. Conclusion: There was significant correlation between BMI and static balance of left leg and no correlation was established between BMI and static balance on right leg and also no correlation was established between BMI and static and dynamic balance for right and left leg. KEY WORDS: Static balance, Dynamic balance, Body Mass Index, Obesity, Limb length.

Objective: The present study aimed to evaluate the reliability of functional balance tests and their correlation with selected anthropometric parameters in children aged 7-10 years. Methods: Participants were 80 students aged 7-10 (40 female and 40 male). Romberg Test and Sharpened Romberg Test were used for assessing static balance, while timed up and go test, tandem walk test, and Y-balance test were used for measuring dynamic balance. Selected anthropometric factors were body height, upper body length, lower body length, Foot length and body mass. Reliability was determined using intra-class correlation coefficient (ICC), and Pearson correlation was used for examining the relationship between balance tests and selected anthropometric parameters at a significance level of P≥0.05. Results: Static balance tests were not reliable, but dynamic tests were reliable. No significant correlation was found between anthropometric parameters and static and dynamic tests (P>0.05); except between lower body length and Y-balance test (r=0.53, P=0.01). Conclusion: It seems that at the age of 7-10 years, static balance tests are affected because the sensory systems related to balance are developing. Therefore, static balance tests, which require weighting of each of these systems with eyes closed and open, are not good criteria for examining the balance of this age group. Hence, it is better to use dynamic balance tests, especially the Y-balance test.

Balance ability among the elderly is a key component in the activities of daily living and is divided into two types: static and dynamic. For clinicians who wish to assess the risk of falling among their elderly patients, it is unclear if more than one type of balance test can be used to measure their balance impairment. In this study, we examined the association between static balance measures and two dynamic balance field tests. One hundred and twelve community-dwelling older adults (mean age 74.6) participated in the study. They underwent the Tetrax static postural assessment and then performed the Timed Up and Go (TUG) and the Functional Reach (FR) Test as dynamic balance tests. In general, low-moderate correlations were found between the two types of balance tests. For women, age and static balance parameters explained 28.1–40.4% of the variance of TUG scores and 14.6–24% of the variance of FR scores. For men, age and static balance parameters explained 9.5–31.2% of the variance of TUG scores and 23.9–41.7% of the variance of FR scores. Based on our findings, it is suggested that a combination of both static and dynamic tests be used for assessing postural balance ability.

Background and Study Aim. The aim of this study is to identify and correlate some factors that are thought to affect the dynamic-static balance and proprioceptive senses of elite level wrestlers. Material and Methods. Descriptive statistics of a total of 13 volunteer elite freestyle wrestlers were determined after body weights, height, WAnT, active-squat jump tests, proprioceptive sense measurements, static and dynamic balance test measurements were taken. Then, the relationship test with the values obtained from static-dynamic balance and proprioceptive sense measurements, the Wingate anaerobic power test (WAnT) and vertical jump (active-squat) was examined. Results. As a result of Pearson Products Moment Relationship analyses, a significant relationship was found between static balance measurements and, WAnT anaerobic performance measurements, anaerobic performance measurements obtained from jumping, lower extremity isoinertial strength imbalance measurements (p>0.05). In addition, a significant relationship was found between dynamic balance measurements and WAnT anaerobic performance measurements (p>0.05). In addition, a significant relationship was found between proprioceptive joint angle deviation values and WAnT anaerobic performance measurements, anaerobic performance measurements obtained from jumping, and lower extremity isoinertial strength imbalance measurements (p>0.05). Conclusions. In conclusion, as the findings of the study, the determining factors of the balance and angular error rates differ in the left and right legs of wrestlers. Especially, in order to minimize left leg balance and angular errors, training modules that increase proprioceptive performance should be applied to athletes.

Objectives: Lower extremity muscles are critical for maintaining dynamic balance and athletic performance. Fatigue of these muscles may affect dynamic balance. It is unclear whether fatigue in a particular muscle group can affect dynamic balance more than that in other groups. This study was conducted to evaluate and compare the effects of fatigue in 5 muscle groups on dynamic balance in volleyball players. Methods: Fifteen healthy male volleyball players separately performed the Star Excursion Balance Test before and immediately after the occurrence of fatigue of ankle Plantar Flexor (PF), knee extensor, knee flexor, hip abductor, and hip adductor muscles. Composite reach distance and distance in anterior, posteromedial, and posterolateral directions were recorded, accordingly. Results: Repeated-measures Analysis of Variance (ANOVA) data indicated that fatigue of all muscle groups significantly decreased the mean score of composite (P<0.001). Anterior, posteromedial, and posterolateral distance scores decreased following muscle fatigue of knee extensors and ankle PFs (P<0.05). Discussion: This study suggested that regarding composite reach score, fatigue of ankle, knee, and hip muscles similarly decreased dynamic balance. However, evaluating three main directions revealed that knee extensors and ankle PFs muscles fatigue presented more prominent effects on the explored volleyball players’ balance, compared to the other muscles.

AbstractThe purpose of this study was to assess the effect of ankle external supports on proprioception and dynamic balance in volleyball players. Seventeen female volleyball players (18.94±2.49 years; 65.45±9.49 kg; 1.71±0.05 m; BMI=22.0±2.67 kg/m²) took part in this study. The dynamic balance was assessed through the Star Excursion Balance Test (SEBT). Comparisons between stabilization (no stabilizer/NS, orthosis/ORT and functional bandaging/FB) modes and the SEBT grid lines and inter-limb were carried out. The SEBT assessment showed a significant difference between the groups NS x ORT and NS x FB (p < .01), and between the lines (p< .01). Significant line/limb interaction in DL and NDL (p< .01) was detected. The external supports tested herein showed similar effects on balance, restricting lower limb's reach in the SEBT execution in some of tested directions.
