Effect of the amount of allowed visual information on acrobatic skill learning
Postural control is the result of different sensorial information integration. During complex movements, such as acrobatic skills when a subject jumps and turns on the transversal axis, sensorial conflicts can appear, especially among visual and vestibular inputs. The importance of these conflicts during learning and posterior execution of an acrobatic manoeuvre is not clear. An experimental study was carried out where we controlled the environmental illumination of flying and landing phases of an acrobatic skill execution (forward tucked somersault) during the learning process. We obtained significant differences between different practice groups, showing better results those subjects who accomplished their practice without illumination during the landing phase. Our results suggest that although visual information might be important to perform the take-off phase correctly, it doesn’t seem to be a determining factor on its final phase (landing) and could even interfere with vestibular information.
