“…Chapman et al (2008) have previously suggested expert surfers could shift the sensorimotor dominance from vision to proprioception for postural maintenance. The lower dependence on vision for postural control in expert surfers may be the illustration of a greater competence to perform technical figures while maintaining balance than other surfers.…”

This work analyses surfers' postural control and their use of visual information in static (stable) and dynamic (unstable) postures according to their level of competition. Two groups of healthy surfers were investigated: a group of local level surfers (LOC) (n = 8) and a group of national/international level surfers (NIN) (n = 9). Posture was assessed by measuring the centre of foot pressure with a force platform for 50 s with stable support and for 25 s with unstable support (sagittal or frontal plane). The tests were completed with the eyes open (the subjects looked at a fixed level target at a distance of 2 m) and closed (they kept their gaze in a straight-ahead direction). Results showed that the contribution of vision in postural maintenance, with unstable support was less important in the NIN surfers than in the LOC surfers and that the NIN surfers had better postural control than the LOC surfers. Firstly, the results suggest that expert surfers could shift the sensorimotor dominance from vision to proprioception for postural maintenance. Secondly, there is a relationship between the postural ability and the competition level of surfers. These observations are likely to induce new prospects of training for surfers.

“…Regarding sensory organization of the standing balance, it has been documented that postural stability in some sports as, for instance, in soccer players, professional dancers, gymnasts and surfers, has strong visual dependence, unlike in judoists and triathlonists, where such dependence was not established (Chapman et al 2008;Paillard and Noe 2006;Perrin et al 2002;Schmit et al 2005;Nagy et al 2004). The finding of Caillet et al (2006) is very interesting.…”

Postural stability of canoeing and kayaking young male athletes during quiet stance

et al. 2011

We studied the postural stability of 23 canoeing and kayaking young athletes and 15 healthy untrained age matched subjects during quiet and sensory conflicted stance (standing on stable and foam support with open and closed eyes). We measured with a force platform the center of pressure excursions and applied mean sway amplitude (MA), mean sway velocity (SV) and their Romberg ratios, and sway dispersion index to evaluate standing balance. During standing with eyes open, the athletes in comparison to non-athletes showed in sagittal and frontal plane greater MA and SV when the support was stable and smaller MA and SV when it was unstable. During standing with eyes closed, there were no differences between groups when the support was stable, however, the athletes sway faster and have smaller MA than controls while standing on the foam support. During standing on stable support, Romberg ratios for MA and SV revealed that unlike non-athletes the athletes' MA and SV were vision independent. However, while standing on unstable support the athletes' MA and SV became vision dependent and even greater for the medio-lateral sway. Canoeists' SV vision dependency in both planes was greater than for other groups. These results are in line with our hypothesis that young kayaking and canoeing athletes have a different from non-athletes model of sensory integration due to their specific sporting activity. One possible mechanism of this model may be a subtle re-adaptation deficit after disembarking to stable ground with diminished sensitivity of vision and vestibular apparatus.

“…According to Marteniuk (1976) a perceptualcognitive skill can be defined as the ability to identify and acquire environmental information for integration with existing knowledge to facilitate the selection of an appropriate response to be executed. Given the missing research on perceptual-cognitive skills in surfing, the present study investigates decision making in surfing as to date only physical factors such as postural control (Chapman, Needham, Allison, Lay, & Edwards, 2008) or upper body strength and fitness have been shown to be important factors in elite surfing.…”
