“…In previous studies, including one from our research team, 26 the one-legged stance task was a sufficient challenge to discriminate postural instability between different sports modalities and training experience, such as taekwondo, handball, American football, soccer, and nonathletes, 14,26,27 which supports the use of this condition in the present study. However, no study has investigated the effects of knee posture at 30°of flexion on postural control based on COP parameters in athletes with CLBP, which in turn, adds a challenge to the discussion of our findings.…”

“…In fact, the one-legged stance with knee extension has been examined in previous studies, including those athletes with CLBP. 7,14,[24][25][26][27] However, knee extension constitutes a locking mechanism, a kinematic phenomenon also known as the screw home that increases knee stability 28 ; contrary, the knee flexion position above 20°constitutes a position frequently adopted during most sports where the screw home mechanism is absent. At this knee position, the individual can present an articular mobility with signs of joint instability 28 and, consequently, increase their chances to have lumbar or lower-limb instability and back injury.…”

Context: Chronic low-back pain (CLBP) may be associated with changes in postural balance in athletes as poor postural control during sports practice. Objective: To compare the postural control of athletes with and without CLBP during 2 one-legged stance tasks and identify the center of pressure (COP) cutoff values to determine the main differences. Designed: A cross-sectional study. Setting: Laboratory of functional evaluation and human motor performance. Participants: A total of 56 male athletes, 28 with and 28 without CLBP (mean age = 26 y). Intervention: The one-legged stance with knee extension and with the knee at 30° flexion tasks were measured and analyzed on a force platform. The participants completed three 30-second trials (30 s of rest between each trial). Main Outcome Measures: The COP parameters: the area of COP, mean COP sway velocity in both the anteroposterior and mediolateral directions, and total COP displacement were computed, and a receiver operating characteristics curve analysis was applied to determine the group differences. Results: Athletes with CLBP had poorer postural control (P < .01) in both tasks. The 30° knee flexion reported more postural instability than the knee extension for all COP parameters (a large effect size d = 0.80).The knee extension cutoffs identified were >7.1 cm2 for the COP area, >2.6 cm/s for the COP sway velocity in the anterior-posterior direction, and >3.2 cm/s for the mediolateral direction. Whereas, the 30° knee flexion cutoffs were >10.9 cm2 for the COP area, >2.9 cm/s for the COP sway velocity in the anterior-posterior direction, and >4.1 cm/s for the mediolateral direction. Both measures showed enough sensitivity and specificity (ie, area under the curve = 0.88 in and 0.80, respectively) to discriminate both groups. Conclusions: The athletes with CLBP had poorer postural control than the healthy athletes and obtained specific cutoff scores from the COP values.

“…In addition, sports training can increase the ability to use somatosensory information, also resulting in improved postural balance. 10,11 The study by Heleno et al 12 showed that a five-week sensory-motor training program, with static and dynamic exercises associated with soccer movements, improved the functional performance and postural control of young soccer players. These findings corroborate the evidence that the practice of sports activities can increase physical fitness and decrease the fatigue parameters that are critical for postural balance.…”

Introduction: Postural balance is essential for activities of daily living and sports performance in all life phases, but it remains unknown whether the regular practice of sports activities can improve postural balance in children. Objective: To evaluate postural balance in children who practice and those who do not practice regular sports activities. Methods: The sample consisted of 60 children (7-13 years of age) divided into two groups: participants in sports activities (n = 30) and non-participants in sports activities (n = 30). The level of physical activity was assessed by applying the Physical Activity Questionnaire for Children (PAQ-C) and static postural balance was assessed on the BIOMEC400-412 strength platform in bipedal and unipedal support. Results: No significant difference was observed between the groups in age, height or body mass index (p > 0.05). However, the groups showed a significant difference (p < 0.001) in the level of physical activity. The practicing sports group was characterized as active and the non-practicing group as sedentary. The practicing sports group had better postural balance in both bipedal and unipedal support compared to the non-practicing group (p < 0.05). Conclusion: The practice of regular sports activities improves postural balance in children from 7 to 13 years of age. Level of evidence II; Diagnostic study - Investigating a diagnostic test.

“…The authors report that for taekwondo the center of gravity of the right foot corresponds on average to 600 mm 2 , while for the left it corresponds on average to 700 mm 2 ; for Handball, the center of gravity of the right foot corresponds on average to 1100 mm 2 , while for the left it corresponds to an average of 1100 mm 2 and for American football the center of gravity of the right foot corresponds to an average of 1100 mm 2 , while for the left it corresponds to average at 1100 mm 2 ; In the present study, a better stabilometric performance is observed in the areas of the right center of gravity, with a record of 55 mm 2 on average and for the left foot of 21 mm 2 . These results are due to greater motor control at the stabilometric level given by constantly working on the unstable base represented by the skateboard, the duration of sports practice per day and the dynamics of the sport [20].…”
