Análise do controle do equilíbrio em surfistas durante a postura ereta

Abstract

Background: Surfing is a sport that has become considerably popular, which increased interest in research about the aspects that can influence on the performance of these athletes, such as injuries, aerobic fitness and reaction time. Due to the ever-changing environment and high instability required for surfing, the surfers must develop some neuromuscular skills (agility, balance, muscle strength and flexibility) to acquire better performance in this modality. Nevertheless, there are still few scientific studies concerned about the investigation of these motor skills in surfing. Objective: The aim of this study was to evaluate the balance control in surfers compared to practitioners of other physical activities. Methods: Participants remained on a force platform while performing tasks involving visual deprivation (eyes open or closed) and somatosensory disturbance (steady surface or use of foam), with covariation of experimental conditions. The following variables were analyzed: speed and root mean square (RMS) displacement of the center of pressure in the anteroposterior (AP) and mediolateral (ML) directions. Results: The results showed no difference between groups during the experimental conditions, that is to say, both surfers and the control group varied over the conditions of eyes closed and on foam. Conclusion: Although surfing requires the surfer to have great balance control, the results did not reveal a relationship between this sport and better performance in balance control. However, we must consider the small sample size and the fact that this sport requires dynamic balance, while the study evaluated static balance.

Study of the effect of suspension training on the balance ability of surfers without relying on vision

“…This nding is more controversial at the current time, other researchers have compared the static balance of surfers, Chapman et al (2008) assessed the static balance of elite and intermediate surfers on a balancing platform and found no difference between the two groups. Furthermore, Alcantara et al (2012) found no differences in static balance performance between recreational surfers and controls. However, as sur ng takes place in an ever-changing and volatile environment, static equilibrium enhancements and needs may not be very clearly discernable (Hrysomallis, 2011).…”

“…Due to the ever-changing environments and high level of instability required for sur ng, surfers must develop a number of neuromuscular skills (agility, balance, muscle strength and exibility) for better performance. This involves visual deprivation (eyes opening or closing) and impairment of somatic sensation (stabilizing surfaces or using bubbles) (Alcantara et al, 2012). The training methods in this study created an unstable environment, trained somatosensory perception, and enhanced dynamic balance.…”

Associação entre dor lombar e aspectos cinético-funcionais em surfistas: incapacidade, funcionalidade, flexibilidade, amplitude de movimento e ângulo da coluna torácica e lombar

“…Similarly, recreational surfing may cause beneficial adaptations to the neuromuscular function on the long term, with lower rates of posture oscillation in the standing position, with closed eyes and in a smooth surface 2 . However, when we compare amateur surfers with active individuals who perform different sports, there is no different in their balance control 10 . Thus, we conclude that lower back pain in surfers is not caused by posture instability, since higher rates of oscillation may be related to low back pain 11 .…”
