“…Lateral asymmetries were found in the Dm and in the Vrn of VL and VM, RF and BF of volleyball players 26. In addition, TMG has shown excellent reproducibility of lateral symmetry in these athletes 58. In professional cyclists it has been reported that there are no significant differences in VL, VM, RF and BF between the right side and left the side, in terms of Dm and Tc 16,17.…”

An exhaustive review has been made to filter the studies that have analyzed muscle function though tensiomyography (TMG) with elite or well-trained athletes. The results of this review indicate that the several protocols used in athletes to find the displacement-time curve with greater maximum radial muscle displacement showed a good-excellent reliability. TMG has been used to characterize athletes’ muscles contractile properties from specific sports disciplines, although there are very few sports that have been deeply analyzed. TMG seems to be useful to determine changes in muscles contractile properties after stimuli of competition, training or recovery. These changes have been strongly related with the fatigue produced after an effort. In addition, TMG parameters could be used to control training effects during a specific period or throughout the season being also a very useful tool to individualize athletes training loads. In this sense, it also seems to provide sports performance information in cyclic sports by relating some TMG parameters with performance indicators. On the other hand, the TMG-BCM algorithm has been used as a lateral and functional symmetry measure and as a monitoring tool for injury prevention and recovery. However, it seems to be no clear criterion that determines asymmetry degree, nor established contractile properties values as a reference to prevent or recover sports injuries. Despite the utility shown in these fields, there are still very few sports analyzed and it is really necessary to continue advancing in the knowledge of the contractile properties behavior, such as the effects of athletes’ training, competitions and injuries and even in the parameters interpretation obtained with the TMG.

“…However, our findings are in line with the high interday reliability found in other jump tests, such as the CMJ (7) with a movement pattern similar to the volleyball attack take-off. In addition, the high intrareliability found in this test (20) seems to point out that it is a very useful jump test to control volleyball players' performance. This high interday and intraday reliability could possibly be due to the high number of repetitions that volleyball players perform this technical gesture.…”

“…However, lateral asymmetry results could depend on the reliability of the tests that have been used for its detection because not all tests have the same intraday reliability in well-trained volleyball players (20). In addition, it still seems necessary to determine the most appropriate method to calculate the asymmetry based on whether the best performance value is retained for the analysis or, on the contrary, the average value of the different attempts made as recommended by Bishop et al (3).…”

Iglesias-Caamaño, M, Álvarez-Yates, T, Carballo-López, J, Cuba-Dorado, A, and García-García, O. Interday reliability of a testing battery to assess lateral symmetry and performance in well-trained volleyball players. J Strength Cond Res 36(4): 895–901, 2022—This study aimed to determine the relative and absolute interday reliability of a testing battery for lateral asymmetry detection and performance in well-trained volleyball players and to determine whether retaining for analysis the best or the average value of 3 attempts would modulate the interday reliability and the magnitude of asymmetry. Thirteen Superleague-2 male volleyball players performed on 3 different days a 5-test battery composed of 4 tests for assessing muscle asymmetries: active knee extension, Y-balance test (YBT), modified 20-yard shuttle run (M-20Y), and single-leg countermovement jump; and one for volleyball sports performance: attack jump (AJ). The intraclass correlation index and coefficient of variation (CV) together with the standard error of measurement (SEM, %SEM) and the minimum detectable change (MDC, %MDC) were taken to calculate relative and absolute reliability. Two-way repeated-measures analysis of variance was used to establish the differences between the best value and the average value in each session. The low %MDC (<10%) suggests that all the tests that make up the testing battery would have good sensitivity to detect possible asymmetries. All tests have shown an excellent interday absolute reliability (CV <4.5%; %SEM < 5%), both when retaining the best value and the average value of the 3 attempts. In addition, AJ and YBT (on both legs) obtained a good-excellent relative reliability, whereas the M-20Y test seems to show a lower relative reliability. Retaining the best value or the average value to determine the magnitude and direction of asymmetry seems to be equally reliable with no differences between both values.

“…Up : (CV X , CV Y ) = (2, 3) and (m, n) = (500, 700); down : (CV X , CV Y ) = (3,5) and (m, n) = (700, 1000). Table 3 indicates that all p-values are more than 0.05 and consequently the Shapiro-Wilk's test verified the normality of the proposed test statistic.…”

“…The division of the standard deviation to the mean of population, CV = σ µ , is called as coefficient of variation (CV) which is an applicable statistic to evaluate the relative variability. This free dimension parameter can be widely used as an index of reliability or variability in many applied sciences such as agriculture, biology, engineering, finance, medicine, and many others [1][2][3]. Since it is often necessary to relate the standard deviation to the level of the measurements, the CV is a widely used measure of dispersion.…”

Coefficient of variation (CV) is a simple but useful statistical tool to make comparisons about the independent populations in many research areas. In this study, firstly, we proposed the asymptotic distribution for the ratio of the CVs of two separate symmetric or asymmetric populations. Then, we derived the asymptotic confidence interval and test statistic for hypothesis testing about the ratio of the CVs of these populations. Finally, the performance of the introduced approach was studied through simulation study.
