This study examined postural sway in children in eyes open (EO) and eyes closed (EC) conditions, controlling for body mass index (BMI) and physical activity (PA). Sixty two children (aged 8–11years) underwent sway assessment using computerized posturography from which 95% ellipse sway area, anterior/posterior (AP) sway, medial/lateral (ML) sway displacement and sway velocity were assessed. Six trials were performed alternatively in EO and EC. BMI (kg/m2) was determined from height and mass. PA was determined using sealed pedometry. AP amplitude (p = .038), ML amplitude (p = .001), 95% ellipse (p = .0001), and sway velocity (p = .012) were higher in EC compared with EO conditions. BMI and PA were not significant as covariates. None of the sway variables were significantly related to PA. However, sway velocity during EO (p = .0001) and EC (p = .0001) was significantly related to BMI. These results indicate that sway is poorer when vision is removed, that BMI influences sway velocity, but that pedometer-assessed PA was not associated with postural sway.

In particular, during accurate, constant force production tasks in isometric conditions with visual feedback, turning the feedback off results in a slow consistent drift of the force, typically to lower

, this delay may be explained by a conviction to enduring traditions engrained in CEPs. CDTPs, on the other hand, do not carry the weight of history with them. It is our hope that this gives them the ability to be responsive and receptive to feedback. If so, there is potential to prompt change in

One potential avenue is through visual feedback manipulation in which the squat provides the ideal exercise for such investigation. Normally during the execution of a squat, the athlete maintains an upright posture with a forward

Kinesthesia, the sense of body movement, is widely acknowledged to play an important role in functional mobility. Both proprioceptive receptors (eg, muscle spindles) and cutaneous receptors (eg, Ruffini corpuscles) can provide sensory feedback related to body segment position or velocity, thus
