To investigate the effect of gastrocnemius muscle fatigue on postural control ability in elderly people. Twenty-four healthy elderly people participated in this study. The postural control ability of single leg standing was evaluated with Health Improvement & Management System (HIMS) posturography before and after fatiguing exercises. After evaluat...

The axe kick, in Olympic style taekwondo, has been identified as the most popular scoring technique aimed to the head during full contact competition. The first purpose of this study was to identify and investigate design issues with the current World Taekwondo Federation approved chest protector. A secondary purpose was to develop a novel chest pr...

... In recent years, World Taekwondo incorporated modern technology into the discipline, i.e., the Protector Scoring System (PSS), the instant Video Replay System (VRS), and relevant competition rule changes [12][13][14][15][16]. The latest revisions in Olympic taekwondo rules penalize non-fighting actions, the presence of "phantom striking", and unnecessary leg elevation; limit possible fouls; and modify the scoring system. ...
... Postural sway is an indicator of displacement and motor corrections to maintain the COM within the BOS (Golriz et al., 2012). Previous investigations have shown that postural sway measures derived from center-of-pressure (COP) displacements during quiet standing are related to postural instability induced by muscle fatigue (e.g., Nam et al., 2013;Singh et al., 2009). The COP-based postural sway measures are also sensitive to demonstrate differences with altered visual, vestibular, and/or somatosensory inputs (Hansson et al., 2010;Riley and Clark, 2003), which can be negatively affected by prolonged exposure to WBV. ...
