“…Supporting our principal result, two previous studies reported moderate (Sekulic et al, 2013) and low (Sekulic et al, 2014) signi cant correlation between static balance and agility measures among collegeaged boys and girls and pubescent boys respectively. Despite the general correlation that we found (i.e., composite scores), the association was only showed among boys.…”

“…Nevertheless, scienti c literature that provides direct agility/balance relationship is scarce, especially in children. To the best of our knowledge, only two studies with college-aged and pubescent participants established a direct correlation between agility and static balance measures, reporting a signi cant correlation between the aforementioned variables (Sekulic, Spasic, & Esco, 2014;Sekulic, Spasic, Mirkov, Cavar, & Sattler, 2013). However, test providing dynamic conditions are required in to identify balance de cits, fall risk and sport-related injury risk in prepubertal children (Granacher & Gollhofer, 2012).…”

Agility and dynamic balance are crucial skills in prepubertal physical activity and sport participation, so the identification of efficient tests for their assessment is necessary. To evaluate the correlation between agility and dynamic balance in primary school children. Twenty-seven boys and twenty girls aged 10 years, volunteered to participate in the study. The modified Star excursion balance test and the 4x10 m shuttle run test were used in order to assess dynamic balance and agility respectively. Dynamic balance composite scores with the right stance showed a moderate significant correlation (r = -0.51, p < 0.05) with the agility test only among boys. However, significant correlation among girls (r = -0.45, p < 0.05) was showed during the posterolateral reaching distance of the Star excursion balance test. The performance of the complete test or the posteromedial and posterolateral reaching distances of the Star excursion balance test is moderately associated with agility among boys, whereas the posterolateral distance is associated with agility among girls.Key words: Dynamic balance, agility, primary school. ResumenLa agilidad y el equilibrio dinámico son habilidades cruciales en la actividad física prepuberal y la participación deportiva, por lo tanto es necesaria la identificación de pruebas eficientes para su evaluación. Evaluar la correlación entre la agilidad y el equilibrio dinámico en niños escolares de primaria. Veintisiete niños y veinte niñas de 10 años participaron voluntariamente en el estudio. El Star Excursion Balance Test (SEBT) modificado y el 4x10 m Shuttle Run Test se utilizaron respectivamente para evaluar el equilibrio dinámico y agilidad. Las puntuaciones compuestas del equilibrio dinámico con apoyo diestro mostraron solo entre los niños una moderada correlación significativa (r = -0.51, p < 0.05) con la prueba de agilidad. Sin embargo, entre las niñas se mostró una correlación significativa (r = -0.45, p < 0.05) durante la distancia de alcance posterolateral obtenida en el SEBT. La realización del test completo o de las distancias alcanzadas a nivel posteromedial y posterolateral del SEBT se asocia moderadamente con la agilidad entre los niños, mientras que la distancia posterolateral se asocia con la agilidad entre las niñas.Palabras clave: Equilibrio dinámico, agilidad, escuela primaria.

“…Balance testing was performed during three trials each lasting 20 s, with 2-3 min rest between trials. The reliability was appropriate with the ICC ranging for 0.76-0.81 (for boys) and 0.79-0.81 (for girls), which was consistent with previous studies conducted on similar samples of participants (Sekulic et al, 2014). Also, repeated measures ANOVA calculated between testing trials found no significant effects, emphasizing no systematic bias (i.e.…”

Balance is hypothesized to be important in alpine skiing, while it is known that balance depends on anthropometric indices. The aim of this investigation was to explore the association between balance, anthropometrics and skiing-results over two competitive seasons among youth alpine-skiers. Eighty-one skiers (40 females) participated in this study. The participants were tested twice over two competitive seasons: when they were 12-13 years old (U14) and when they were 14-15 years old (U16). The variables consisted of anthropometrics (body height and body mass) and three balance indexes (medio-lateral-, anterio-posterior- and overall-stability-index). Additionally, skiing results in U14 and U16 were evaluated. The balance status did not change significantly over the observed period of time regardless of the significant changes in body mass and height. The relationships between balance and skiing results were higher in the U14 (Pearson’s r = 0.45-0.54) than in the U16 (Pearson’s r = 0.05-0.28). The relationships between anthropometrics and competitive results were generally stronger in girls (Pearson’s r = 0.39-0.88) than in boys (Pearson’s r = 0.26-0.58). After clustering athletes into three achievement groups on a basis of their competitive performance, discriminant canonical analysis showed that relationships between balance and skiing results decreased, while the relationships between anthropometrics and skiing results increased over the two observed seasons. This study highlighted the importance of balance in youth alpine skiing in the age range of 11-14 years.

“…The main difference between "stop'n'go" scenarios and the previously described "Y-shaped-course" scenario is that the latter scenario lacks a moment of "zero velocity" (i.e., "Y-shapedcourse" agility consists of nonstop running). The distinction between "nonstop" and "stop'n'go" agility has been directly proven in recent studies, which demonstrated separate predictors for these 2 scenarios (10,11,15). Therefore, it is reasonable to conclude that the "Y-shaped course" is not an appropriate template with which to study reactive agility for all sports (12).…”

The main objective of this study was to evaluate the reliability and the validity of a newly constructed reactive-agility test that can be used to define the reactive-agility performance in sports that employ repeated scenarios of "stop'n'go" agility. Measuring is done by original hardware based on the ATMEL microcontroller AT89C51RE2. A total of 36 college-aged male athletes (age, 22.1 ± 2.4 years; body height, 182.45 ± 5.19 cm; body mass, 80.67 ± 7.69 kg) and 21 college-aged female athletes (age, 21.4 ± 2.5 years; body height, 171.45 ± 6.81 cm; body mass, 61.95 ± 6.70 kg) were evaluated for a stop'n'go reactive-agility test (SNG-RAT), stop'n'go change of direction speed (SNG-CODS), countermovement jump, and anthropometrics. The reliability analyses suggested a high consistency for the applied tests (SNG-CODS, intraclass correlation coefficient [ICC] = 0.87 and 0.92; SNG-RAT, ICC = 0.81 and 0.86, for men and women, respectively). The SNG-RAT and SNG-CODS shared <40% of the common variance. The longer version of the SNG-RAT, which included 5 unpredictable changes of direction, was found to be valid among men. At the same time, the shorter version of the SNG-RAT (3 unpredictable changes of direction) is suggested for women because it better discriminates more agile from less agile athletes. Because the SNG-RAT and SNG-CODS were performed on the same course, we believe that simultaneously performing both tests can be beneficial when defining "stop'n'go" agility. This implies that the calculated SNG-CODS to SNG-RAT ratio will allow strength and conditioning coaches to indirectly determine the perceptual and reaction capacities of their athletes.
