Abstract

Although sports practice has been considered effective in generating neuromuscular adaptations associated with postural control improvements, to date few studies have investigated the behavior of postural sway of athletes in response to the manipulation of sensory information such as the addition of tactile sensory cues. Moreover, a large number of studies have shown increased postural oscillations in response to muscle fatigue. However, no investigation has addressed the effects of muscle fatigue on the postural control of specific sports practitioners such as karate fighters and acrobatic gymnasts. As postural control is improved by different types of physical training, particularly those requiring skilled and fast actions, the hypothesis of the present project is that karate and acrobatic gymnastic athletes might be less prone to fatigue-induced postural instabilities, thereby showing a smaller effect of muscle fatigue on postural sway as compared to non-athletes. Therefore, the aim of this project is to compare the effects of plantar flexor muscle fatigue on the control of single leg stance between karate and acrobatic gymnastic practitioners and non-practitioners, during postural tasks performed with and without additional tactile information due to contact of the index finger with an external surface. In addition to the assessment of postural sway parameters, surface electromyography (EMG) of lower limb and trunk muscles will be used to further evaluate the fatigue-induced adaptations on the neuromuscular system. More specifically, analysis of EMG parameters (both in the time and frequency domains) and analysis of EMG-EMG coherence will be held for data associated with a protocol designed to induce muscle fatigue and also for data associated with pre- and post-fatigue postural assessments.
