“…Although lower than the magnitude of upper extremity functional asymmetry, the overall magnitude of functional asymmetry at the lower extremity level ranged from 1.9 to 8.4%, indicating significant functional asymmetries for all lower extremity performance tests. However, due to the task specificity of lower extremity functional asymmetries, there was no occurrence of cross-asymmetry across the functional tests for the lower extremity, as also mentioned in earlier research [12]. The highest asymmetry magnitude was found for the single leg countermovement jump (i.e., 8.4%).…”

“…For instance, the beforementioned study in high-level female tennis players reported that the preferred upper extremity consistently demonstrates superior performances compared to the opposing upper extremity. In contrast, the lower extremity was found to display poor levels of agreement as to which leg performed better across tests (i.e., the kappa coefficients ranged from −0.07 to 0.17), illustrating the direction specificity of lower extremity functional asymmetries [12].…”

“…Along with the occurrence of lean mass asymmetry, the presence of functional asymmetry (i.e., side-to-side differences in physical performance (e.g., strength or power), again expressed as a percentage) has also been established. Consequently, significant magnitudes of upper (i.e., 8.9-15.2%) and lower extremity (i.e., 1.8-9.4%) functional asymmetries have previously been reported in high-level female tennis players [12]. When examining functional asymmetries, it is essential to use a composite test battery (as opposed to isolated testing) given the direction specificity of asymmetries (i.e., which extremity displays higher values and/or is dominant in performance) between different sporting tasks [13].…”

The relationship between lean mass and functional asymmetry in terms of their magnitude and direction was examined in 22 high-level female tennis players (20.9 ± 3.6 years). Lean mass of both upper and lower extremities was examined using Dual X-ray Absorptiometry. Functional asymmetry was assessed using a battery of field tests (handgrip strength, seated shot-put throw, plate tapping, single leg countermovement jump, single leg forward hop test, 6 m single leg hop test, and 505 change of direction (time and deficit)). Paired sample t-tests compared the dominant (overall highest/best (performance) value) against the non-dominant value (highest/best (performance) value of the opposing extremity). Linear regressions were used to explore the relationship between lean mass and functional asymmetry magnitudes. Kappa coefficients were used to examine the consistency in direction between the extremity displaying the highest lean mass value and the extremity performing dominantly across tests. Significant asymmetry magnitudes (p < 0.05) were found for all upper and lower extremity lean mass and functional values. No relationship was apparent between lean mass and functional asymmetry magnitudes (p-value range = 0.131–0.889). Despite finding perfect consistency in asymmetry direction (k-value = 1.00) for the upper extremity, poor to fair consistency (k-value range = −0.00–0.21) was found for the lower extremity. In conclusion, lean mass and functional asymmetries should be examined independently.

This study examined the influence of both anthropometric and physical performance determinants on the likelihood to be selected to progress through a talent identification and development programme in young tennis. Data were collected in 538 young tennis players (323 males and 215 females) from 6 age categories (U8–U13). A principal component analysis was used to generate one anthropometric determinant (based on body height, body weight and maturity offset) and four physical performance determinants: speed and agility (based on 5 m sprint, 20 m sprint and 505 change of direction test); jumping power (based on standing broad jump and standing broad jump in series); motor coordination (based on balancing backwards and jumping sideways) and tennis ball control (based on a throw and catch test and hold tennis ball up test). For all determinants, tertiles were generated for every age category and both sexes separately. Univariate binary logistic regressions were performed to examine the influence of each determinant on the chances to be selected to progress in the talent identification and development programme. Significant odds ratios were found for all included anthropometric and physical performance determinants ( p < 0.05), ranging from 0.26 to 7.50 in the male young tennis players and from 0.18 to 6.87 in the female young tennis players. The included determinants influenced selection chances mostly in the early age categories (U8–U10) as opposed to the later age categories (U11–U13). Future research should examine the influence of additional determinants (such as tennis (match-play) performance) on the selection chances to progress through a talent identification and development programme.

“…A very common and reliable test for assessing this characteristic is the 505 COD test [9]. Given that the 505 COD test closely mimics tennis actions, and therefore represents a high ecological validity, it is unsurprising that this test has frequently been used to monitor tennis performance as well as to assess side-to-side differences in performance among tennis players [7,[10][11][12].…”

Longitudinal investigations on the development of inter-limb asymmetry in sports is scarce. This study examined the development of change of direction (COD) asymmetry magnitude in youth elite tennis players. Dominant (overall best performance) and non-dominant (best performance on the other side) scores and COD asymmetry magnitude were quantified annually (up to six years) in 323 male and 235 female players (aged 6 - 13 years). Linear mixed effects regression models examined the development of COD performance and asymmetry magnitude according to players’ chronological age and sex. Kappa coefficients examined the consistency for the direction of asymmetry across test occasions. Regardless of sex, COD performance significantly improved (p < 0.001) whilst COD asymmetry magnitude significantly decreased (-0.17 ± 0.87 % / year) with increasing chronological age. Regardless of age, males showed significantly lower COD times (-0.111 ± 0.091 s) and lower COD asymmetry magnitude (-0.30 ± 1.00 %) compared to females. The slight and poor (k-value = 0.02 - 0.00) kappa coefficients for males and females, respectively, highlight the direction specificity of functional asymmetry. These data show that whereas performance of the COD test improved, the magnitude of COD asymmetry reduced across chronological age in youth tennis players.
