“…The kappa coefficient, calculated to know the direction of asymmetries, showed only "fair" side consistency of asymmetry between tests (−0.36 to 0.23). These results are in accordance with Arboix-Alió et al [16] who found no significant relationships between the asymmetry values of different neuromuscular tests in rink hockey players. In line with other studies in different team sports, the present investigation failed to demonstrate the relationship between asymmetry scores on different tests [13,46,47].…”

“…The highest mean was obtained in the SLCJ-V test (8.09 ± 6.86 %). This value is slightly lower than the mean reported by Arboix-Alió et al [16] (9.60%) in a similar sample. Similarly, the ASI mean values for the SLCJ-H (2.91 ± 2.62%) and COD (2.16 ± 1.55%) tests were also lower than those reported by Arboix-Alió et al [16].…”

The magnitude of inter-limb asymmetries has been reported in several studies in different team sports but only some of them have analysed their effects on sports performance. The main purpose of this cross-sectional study was to determine inter-limb asymmetries and examine their relationship with different physical performance tests in rink hockey players. Nineteen rink hockey players (age: 23.37 ± 4.82 years; body height: 1.75 ± 0.06 cm; body mass: 73.16 ± 9.87 kg) performed a mid-season battery of fitness tests consisting of 30 m sprint, countermovement jump (CMJ), and half back squat. Inter-limb asymmetries were assessed using the single leg vertical countermovement jump test (SLCJ-V), single leg horizontal countermovement jump test (SLCJ-H), and 180° change of direction test (COD). Results show a significant relationship between asymmetry in the SLCJ-H test, 30 m sprint (r = 0.63, p < 0.01) and CMJ performances (r = −0.52, p < 0.05). Additionally, asymmetry in the SLCJ-V showed a significant relationship with CMJ performance (r = −0.46, p < 0.05). These findings suggest that training programs should aim to reduce the inter-limb asymmetries in rink hockey players to improve their performance. Practitioners and coaches can use this information to assess the potential impact of asymmetries on physical performance in rink hockey players.

“…Asymmetries observed in the different functional tests also showed notable differences. This finding is in line with Fort-Vanmeerhaeghe et al (2015) and Arboix-Alió et al (2018) who did not find a relationship between the ASI values of different neuromuscular tests in basketball and roller hockey players, respectively. Moreover, in several players, the HPL differed between tests, showing the task-specific nature of both the direction of asymmetry and superior performance capabilities.…”

The direction of inter-limb asymmetries and the change of direction (COD) deficit are two aspects that have increased in recent years. The main objective of the present study was to assess the magnitude of neuromuscular asymmetries in an elite youth female team-sports sample and determine its directionality. Secondary objectives were to evaluate the relationship between COD deficit, linear speed and COD time performance. Elite female youth basketball and handball players (n = 33, age = 16 ± 1.17 y) performed the Single Leg Countermovement Jump in vertical (SLCJ-V), horizontal (SLCJ-H), and lateral (SLCJ-L) directions, the COD and the 10-m sprint. Results showed statistical differences between limbs in all the neuromuscular tests (p < 0.001). The Kappa coefficient showed poor to fair levels of agreement between tasks (K range = -0.087 to 0.233), indicating that asymmetries rarely favoured the same limb between skills. Additionally, small and non-significant correlations were found between the linear sprint capacity and the COD ability. The findings of the present study highlight the independent directionality of asymmetries across tests. The COD deficit does not appear to be much more advantageous than COD total time to measure asymmetry. Practitioners are encouraged to use a fitness testing battery to detect existing side differences and each ability should be specifically trained with functional tasks.

Background and Study Aim. The study of functional asymmetry in students and schoolchildren practicing martial arts using a computer test. Material and Methods. The study involved students and schoolchildren (n = 38) practicing the martial arts (taekwondo, karate). Participants were divided into groups according to the sports’ skill level. The first group included experienced athletes (n = 15, age – 19.00 ± 0.45 years). The second group included beginners (n = 23, age - 9.78 ± 0.65 years). The functional asymmetry was determined using «Reaction SM Dual» software for tablets with iOS. Two visual tests were used. The duration of each test was 100 s. Each test was divided into 5 stages. Each stage lasts 20 s. The first test (simple reaction) – the participant pushes against the circles on the screen with two hands. The second test (differentiated reaction) – the participant pushes against the circles of the same color (out of five possible) on the screen. The following indicators were determined: the number of pushes with the right and left hand (abs); reaction time with the right and left hand (s); duration of pushes with the right and left hand (ms). It was estimated the following indicators: total number of pushes; average reaction time; average duration of pushes. Results are estimated using parametric and nonparametric statistical indicators. Results. The number of pushes in the test, the reaction rate, and the duration of pushes were significantly higher in experienced athletes. It was determined the asymmetry due to the lower duration of pushes with the right hand compared to the left hand in beginners. The asymmetry was not confirmed in experienced athletes. The reaction rate for the left hand significantly increased compared to stage 1 in beginners: at stage 2 (t = -2.41), at stage 3 (t = -2.23), at stage 4 (t = -2.30) and at stage 5 (t = -2.68). This dependency was less expressed for the right hand. It was confirmed the increase of the reaction rate in comparison with stage 1: at stage 3 (t = -2.39), at stage 4 (t = -2.00) and at stage 5 (t = -2.32). The differences in the dynamics of the test were more expressed in experienced athletes. It was determined the decrease in the number of pushes compared to stage 1: stage 2 (t = 2.53), stage 4 (t = 2.89) and stage 5 (t = 2.61). For the right hand, this pattern was more expressed. The decrease in the number of pushes was determined compared with stage 1: stage 2 (t = 2.17), stage 3 (t = 2.07), stage 4 (t = 2.39) and stage 5 (t = 2.94). Experienced athletes have confirmed significant changes in the reaction rate with their left hand compared to stage 1: stage 4 (t = -2.33) and stage 5 (t = -2.06). For the right hand, this pattern was confirmed only for the final stage of the test (t = -2.35). Conclusions. It was confirmed the legitimacy of using a special computer test to study functional asymmetry in students and schoolchildren practicing martial arts. The test division into several stages can significantly increase the information content of the results. The applied battery of indicators provides the necessary information for the analysis of asymmetry. It was determined the best functional condition of experienced athletes compared to beginners. Experienced athletes demonstrate the best ability to mobilize and concentrate on extreme conditions. The dynamics of the test also confirms the asymmetry in athletes with less training experience. Performing a test with a differentiated stimulus confirmed the revealed patterns. The lack of asymmetry in experienced athletes confirms optimal training tactics. The asymmetry in beginners stipulates the correction of training. Used computer test can be recommended for martial arts athletes’ condition monitoring.
