“…Single leg balance performance has been significantly related to functional performance [1][2][3] and injuries, such as ankle sprains [4] and anterior cruciate ligament (ACL) deficiency [5]. However, it has been suggested that single leg jump landing tasks may better detect differences in sensorimotor function than static single leg stance, since they are more challenging and sport specific [6][7][8].…”

A B S T R A C TThe single leg drop jump landing test may assess dynamic and static balance abilities in different phases of the landing. However objective definitions of different phases following landing and associated reliability are lacking.Therefore, we determined the existence of possible distinct phases of single leg drop jump landing on a force plate in 82 elite youth soccer players. Three outcome measures were calculated over moving windows of five sizes: center of pressure (COP) speed, COP sway and horizontal ground reaction force (GRF).Per outcome measure, a Factor Analysis was employed with all windows as input variables. It showed that four factors (patterns of variance) largely (>75%) explained the variance across subjects/trials along the 12 s time series. Each factor was highly associated with a distinct phase of the time series signal: dynamic (0.4-2.7 s), late dynamic (2.5-5.0 s), static 1 (5.0-8.3 s) and static 2 (8.1-11.7 s).Intra-class correlations (ICC) between trials were lower for the dynamic phases (0.45-0.68) than for the static phases (0.60-0.86). The COP speed showed higher ICC's (0.63-0.86) than COP sway (0.45-0.61) and GRF (0.57-0.71) for all four phases.In conclusion, following a drop jump landing unique information is available in four distinct phases. The COP speed is most reliable, with higher reliability in the static phases compared to the dynamic phases. Future studies should assess the sensitivity of information from dynamic, late dynamic and static phases.

“…These authors found that the athletes presented better posture strategy, mainly in the M/L direction, than the control group. Generally speaking, great part of the literature supports good balance performance of RG athletes in different postures 24,25 . The stabilometric assessment compared with the functional tests is necessary to point the possible alterations in balance of athletes, and, in the presence of neuromuscular deficit, justify the development of rehabilitation programs and prevention of the dynamic posture control.…”

Introduction: Rhythmic gymnastics requires a high level of physical quality; therefore, good performance depends on muscular strength and endurance, motor coordination and postural balance. Objective: Develop a comparative analysis of postural balance in rhythmic gymnasts. Methods: 10 rhythmic female gymnasts were evaluated on a force platform on one-foot and balance functional tests (Side Hop Test and Figure of Eight Hop Test). The anteroposterior and mediolateral of the center of pressure (COP) parameters were used for the functional tests, while for the functional tests, the performance time-seconds was analyzed. Results: Significant difference (p = 0.01) was found between lower limbs in the mean frequency parameter in the mediolateral direction, in which the non-dominant lower limb presented higher postural stability than the dominant one. For functional tests, there was no significant difference between limbs. Conclusion: The difference found in the control of balance of mediolateral direction may be related with different muscular actions of the hip region, which is present during the sport practice for stabilization, trunk maintenance and maneuvers performance with the lower limbs. These results indicate the need of a balance program and pelvic stabilization for the analyzed athletes in order to maintain muscular symmetry of the limbs for high sports performance.

“…For the bipodal task we observed a lower COP RMS and COP Speed in the a-p direction (sagittal plane) indicating an improvement of the balance performance [i.e. considering the ability to minimize postural sway (Hrysomallis, 2011;Zverev, 2006)]. These results may be related to high demand on stability during different side by side team handball skilled movements, for example, while maintaining a ball possession, passing, dribbling, throwing, resulting in changes of the balance control in this specific plane of motion (sagittal plane).…”

“…Particularly, practicing a sport enhances the ability to use the control of posture by athletes, mainly because of the improvement of somatosensory and otolithic information (Hrysomallis, 2011;. Several studies have shown that the control of one's posture is dependent on the type of sport being practiced (Bressel, Yonker, Kras, & Heath, 2007;Marchetti, Hartigan, & Duarte, 2012;Perrin, Deviterne, Hugel, & Perrot, 2002;Schwesig et al, 2009;Vuillerme et al, 2001).…”

Abstract-It is unclear whether athletes change their postural control over the course of a full sport season, or become more asymmetrical with respect to their neuromuscular performance over the same period. The aim of this study was to investigate the effects of a full sport season on the postural control of team handball elite athletes. Ten healthy, elite male team handball players performed bipodal standing (BP) and right and left unipodal standing (UP) during 30s. We used the RMS and speed of the center of pressure to describe postural sway. For the BP task, the sway was lower at the end of the season (p<0.005). For the UP tasks, the sway was lower at the end of the season only for the non-dominant limb (p<0.001). Differences between limbs were observed only at the end of the season (p<0.03). In conclusion, a full team handball season did not lead to deterioration of the athletes' postural control, but by the end of the season, the athletes were more asymmetrical.Keywords: exercise performance, biomechanics, motor control, postural stability, stabilometry, physical performanceResumo-"Efeitos da temporada completa em parâmetros estabilométricos em atletas de handebol de elite." Não é claro na literatura científica se atletas mudam seu controle postural ao longo de uma temporada esportiva, ou mesmo se tornam mais assimétricos em relação ao seu desempenho neuromuscular durante o mesmo período. O objetivo deste estudo foi investigar os efeitos de uma temporada esportiva completa no controle postural de atletas de elite do handebol. Dez jogadores de elite de handebol, saudáveis, realizaram a tarefa de postura ereta quieta bipodal (BP) e unipodal direito e esquerdo durante 30 segundos. Foi utilizada a RMS e a velocidade do centro de pressão para descrever a oscilação postural. Para a tarefa de BP, a oscilação foi menor após a temporada esportiva (p < 0,005). Para as tarefas unipodais, a oscilação foi menor após temporada esportiva apenas para o membro não dominante (p < 0,001). Apenas após a temporada, foram observadas diferenças entre os membros (p < 0,03). Em conclusão, uma temporada esportiva para o handebol não levou à deterioração do controle postural dos atletas, entretanto no final da temporada, os atletas apresentaram-se mais assimétricos.Palavras-chave: desempenho do exercício, biomecânica, controle motor, estabilidade postural, desempenho físico Resumen-"Efectos de la temporada completa en parámetros estabilométricos en atletas de balonmano de élite."
