“…it did not involve the context in which the athletes are trained. These results are in line with previous ndings which investigated the effect of expertise on the non-ecological context of postural control (static balance) among judokas, surfers, and dancers (15)(16)(17)(18). Moreover, the differences between elite ju-jitsu athletes and controls were observed in the so-called ecological conditions introduced in the present study as the ju-jitsu CS.…”

“…This was observed in lower values of COP range and rms. Many previous reports associated smaller postural sway with better postural skills (17,18,(28)(29)(30)(31). For example, ballet dancers exhibited lower values of COP area, range, and rms than non-dancers in a feet con guration represented the ballet-speci c position (18).…”

“…For example, ballet dancers exhibited lower values of COP area, range, and rms than non-dancers in a feet con guration represented the ballet-speci c position (18). Similarly, signi cant differences between elite dancers and control subjects were majorly found in dance-like techniques, which required weight transfer on the ball of the foot, on an unstable surface, with and without vision, and in ballet jumps, followed by maintaining the new, stable posture (17). In the study by Gauchard et al (32), reduced body sway was observed in karatekas when compared to control subjects, especially in more challenging conditions, i.e.…”

“…For example, in static conditions, i.e. quiet standing, elite judokas, dancers, and surfers did not exhibit better postural stability than their intermediate peers (15)(16)(17). However, it was possible to differentiate them while performing a dynamic postural task on an unstable surface (surfers) or in dance-like positions (dancers).…”

Background: The testing of athletes in ecological conditions is based on the concept that sport-specific adaptations in postural control are observed mostly in positions or tasks that are related to the practice of a specific movement. Due to the high postural control demands of ju-jitsu, it is likely that long-term ju-jitsu training may influence the process of maintaining a stable posture, especially in positions directly related to combat. The purpose of this study was to examine the postural sway characteristics of elite ju-jitsu athletes in ecological and non-ecological conditions with an approach not previously used in martial arts.Methods: The study was conducted on eleven male elite ju-jitsu athletes and ten non-athletes. The data was collected with the use of a force plate under two conditions: quiet standing and ju-jitsu combat stance. Apart from the standard analysis of the spatial-temporal parameters of COP, sensitive methods in COP data processing were used, namely rambling-trembling and sample entropy. The non-parametric U Mann-Whitney test was used to compare both positions.Results: The main findings of the study showed that in quiet standing, elite ju-jitsu athletes and non-athletes had comparable postural control in both the anterior-posterior and mediolateral planes. In contrast, elite athletes had lower values of postural sway and higher values of sample entropy in comparison to the non-trainees in the combat stance (p<0.05). The rambling-trembling decomposition of the COP data did not exhibit additional differences between groups beyond the standard analysis.Conclusions: Our results confirmed the importance of a sport-specific environment in investigating the subtle differences in the postural regulation of elite athletes. The sample entropy results indicated more irregular characteristics of postural sway in the elite ju-jitsu athletes, representing more automated postural control.

“…These authors reported that the more the postural tasks are specific and difficult, the more the athletes’ postural performance can be related to their competition level. Other works corroborate this principle since dance-like postural tasks have made it possible to discriminate expert dancers from intermediate dancers while this was not possible though static postural tasks (Munzert et al, 2018). Paillard et al (2011) observed that surfers at national and international competition levels were distinguished from surfers at local competition level when using dynamic postural tasks carried out on an unstable support (very close to the postural condition implied by surfing) but not when using static postural tasks completed on a stable support.…”

The review addresses the relationship between sport expertise (i.e., sport competition level), postural performance (amount of motion of the center of mass/of pressure of foot or ability to preserve body balance), and postural strategy (geometric organization of different body segments as well as neurobiological involvement of organism). Since the conditions of postural evaluation are likely to influence results, the aim is to compare athletes at different competition levels in ecological postural conditions (specific postural conditions related to the sport practiced) and non-ecological postural conditions (decontextualized postural conditions in relation to the sport practiced). Evidence suggests that the most successful athletes in terms of sport competition level have the best postural performance both in ecological and non-ecological postural conditions. However, in non-ecological conditions, the postural tasks should be preferentially challenging or relatively close to the sport practice stance. Moreover, the most successful athletes also have more elaborate postural strategies compared with athletes at lower competition level. Mechanistic explanations as well as conceptual models are proposed to explain the role of different factors influencing the relationship between sport expertise and postural performance and strategy.

Background The movement of the barbell has been detected as success factor for the snatch and the clean and jerk events. As the barbell’s movement has been shown to be related to the athlete’s body movement, we hypothesized that the latter could be a success factor also for the back squat (BS) event. Hence, this study aimed to investigate postural control during the execution of the BS at different load intensities in powerlifters and weightlifters. Methods Seventeen powerlifters and weightlifters were enrolled and the one-repetition maximum (1-RM) of the BS of each participant was measured. Afterwards, the assessment of postural control during the execution of the BS at different load intensities (i.e. 60%, 70%, 80%, 90%, 100%) of the 1-RM of each participant was carried out through a posturographic platform to measure the displacement of the centre of pressure (CoP). The following parameters were considered: sway path length (SPL), sway ellipse surface (SES), length/surface (LFS ratio), sway mean speed (SMS), CoP coordinates along X and Y planes. Results We found a significant increase in SPL and LFS ratio, and a significant decrease in SMS as the load intensity increased. In detail, we detected a significant difference in: (a) SPL between the BS at 60% and 80%, 60% and 90%, 60% and 100%; between the BS at 70% and 90%, 70% and 100%; between the BS at 80% and 100%; and between the BS at 90% and 100%; (b) SMS between the BS at 60% and 80%, 60% and 90%; (c) LFS ratio between the BS at 60% and 90%, 60% and 100%. Conclusions These results suggest that powerlifters and weightlifters adopt different postural control strategies depending on the load intensity when performing the BS. Our findings showed that higher effort could affect postural control during the BS. Thus, postural control could be considered a success factor for the BS.
