“…In addition, the AKE test has obtained excellent reproducibility results. However, the values obtained by sports medicine students [25], where the ICC was 0.87 (0.58-0.97) in the D and 0.81 (0.41-0.94) in the ND limb, and those obtained by students on a sports rehabilitation course with ICC 0.76 (0.39-0.90) [48], are inferior. This may be due to the fact that the samples used by these authors were not well trained athletes, so the characteristic strength training of volleyball players would imply better values in dynamic flexibility, as the ROM is a multidimensional factor [49].…”

“…The battery of tests consisted of a total of ten tests, the following seven are related to muscle asymmetries assessment: lateral symmetry by tensiomyography (LS), active knee extension (AKE), Y-balance test (YBT), muscular electrical activity in attack jump (MEA-AJ), single-leg squat jump (SLSJ), triple hop test for distance (THTD), and bilateral maximum repetition in leg press (1RMSL), and the following three tests are related to sports performance in volleyball: T-test, counter-movement jump (CMJ), and attack jump (AJ). The tests to evaluate muscle asymmetry have previously shown their usefulness in determining lateral symmetry in athletes of different disciplines, including volleyball [23][24][25][26]. Similarly, the selected performance tests have already been routinely used and indicated as valid in previous investigations in volleyball players [27][28][29].…”

The development of lateral asymmetries in athletes could have an influence on performance or injuries. The aim of this study was to determine the within-day reliability of the symmetry tests and the performance tests, and explore the relationship between them. Eighteen male volleyball players (18.1 ± 2.1 years) participated in this study. Seven lateral symmetry assessments were used, namely: lateral symmetry through tensiomyography (LS), active knee extension (AKE), Y-balance test (YBT), muscular electrical activity in attack jump (MEA-AJ), single-leg squat jump (SLSJ), triple hop test for distance (THTD), and bilateral maximum repetition in leg press (1RMSL); and three volleyball performance tests, namely: the T-test, counter-movement jump (CMJ), and attack jump (AJ). Three in-day measurements were taken from each volleyball player after the recovery was completed. The reliability was calculated through the intraclass correlation coefficient and the coefficient of variation, and the relationship was calculated through Pearson’s bivariate correlation coefficient (p < 0.05). The results indicate that AKE, YBT, and LS are the symmetry tests with increased reproducibility. THTD correlates positively with the AKE test and 1RMSL test, and a greater symmetry in the YBT correlates with a greater performance in the CMJ and AJ performance tests. In conclusion, AKE, LS, and YBT are the best tests to determine, with reliability, the asymmetries in volleyball players, and a greater symmetry in the YBT seems to influence the height of bilateral vertical jump.

“…The larger muscles of the core part of the body create a stable level of motion for the body by providing a solid cylinder and, subsequently, producing more inertia against body turbidity. Abdominal muscles, including the transverse abdominal, right abdomen, internal diagonal, and external diagonal are all integrated to provide spine stability and, subsequently, a stronger reliance on lower limb movements [27]. When the transverse abdominal muscles contract, the internal diagonal muscle pressure increases and causes the lumbar spine to tension.…”

“…These contractions occur before the movement of the organs to allow the organs to have a stable level of muscle movement and activation. On the other hand, the right abdominal muscles and abdominal diagonal muscles are also active in specific patterns relative to the movement of the organs that provide support for the vertebral column [27].…”

Purpose: This study aimed to evaluate the effects of a selected course of the core stabilization of body and hopping exercises on trunk strength and balance of female Kabaddi athletes. Methods:The subjects of this study consisted of 24 female Kabaddi players, who were randomly selected and intentionally assigned to two groups; experimental group (12 persons; Mean±SD age: 16.83±1.26 years, height: 1.61±0.04 m, weight: 56.50±3.06 kg, BMI: 21.84±1.73 kg/m 2 , and exercise history: 05.08±1.08 years) and control group (12 persons; Mean±SD age: 16.42±0.99 years, height: 1.60±0.05 m, weight: 59.08±8.68 kg, BMI: 23.03±1.71 kg/m 2 , and exercise history: 5.25±1.60 years). The experimental group performed a 6-week training program, 3 sessions per week, each session consisting of 40 minutes of core stabilization exercises and hopping. A questionnaire was used to collect demographic information and exercise history, and the Y-balance test and stork stand balance test were used to measure static and dynamic equilibrium, respectively. In addition, the strength of the core part was evaluated by trunk 60° flexion, Biering-Sorensen, forearm plank, and side plank (right and left) tests. The Shapiro-Wilk test was used to check the normality of the data. In the case of normal data, the paired t-test was used to evaluate the differences in mean values. Results:The results of this study showed a significant difference between the mean posttest scores of trunk strength and static and dynamic balance in both experimental and control groups (P<0.001) so that the subjects in the experimental group performed better in these tests. All statistical tests were performed at a significance level of 95% (P<0.05). Conclusion:The results of the present study show that combined balancing exercises for the core part of the body and hopping can improve the balance and endurance of the Kabaddi athletes and, thus, may prevent potential injuries.

Background Participation of children and youth in sporting activities, among others in training and football competitions, is an optimistic manifestation of activation in the current trend of computerization. Unfortunately, this is also often associated with musculoskeletal injuries. An example is the association of dynamic valgus and disturbed dynamic balance with lower limb injuries. The main purpose of the studies is to determine the impact of three strengthening exercises on the parameters of dynamic knee valgus and balance of lower limbs. The secondary objectives are to investigate the dominant influence and the length of lower limb on the valgus values and to determine risk of injury to young football players. Methods 134 young footballers training at the Arka Gdynia SI club were invited to first stage of the research in order to examine anthropometric features and kinematics of the lower limb. Single Leg Squat Test was used, which was recorded. The samples were analyzed video to determine exact knee angle of valgus. During the second stage, to which players with valgus knee were qualified (≥15˚), the Y-Balance Test was additionally used. Intervention group underwent an exercise program to strengthen gluteus medius, popliteal and tibialis posterior muscles for 6 weeks to repeat tests in the third stage. Results Statistical methods used at the assumed level of significance allow to conclude that there are no differences in results of dynamic valgus (≥15˚) and dynamic balance between the intervention group and control group during the 6 week period between stages. In addition, there were results confirming the lack of influence of length and dominant lower limb on valgus. Results of composite direction in the Y-Balance Test test determine the low risk of injury in both intervention and control groups. Conclusions Intervention did not affect the dynamic valgus and knee balance in young football players. Both the length and the dominant limb did not affect the results. The "low risk" occurrence of injuries among the examined participants with valgus knee due to the values of dynamic balance was determined.
