Purpose The purpose of the study was to investigate the effect of vibratory stimulus on the static postural control of 8 healty senior adults. Methods To achieve this goal, all subjects participated in two different kinds of static postural control tasks. Task 1 was a static postural control task, where both-legs stand on the ground. Second task was an unstable static postural control task using only single leg stance. As they maintain their balance, 6 different vibratory stimulus were provided on the sole of their feet(personal threshold 0%, 80%, 90%, 100%, 110%, 120%). Results The results of the study were as follows: First, there was no significant differences in postural control ability according to different types of vibrator intensity. Second, there was a significant difference in single-leg postural control ability according to vibrator intensity. Third, there was a significant difference in anterio-posterior stability according to the different types of vibrator intensity. Conclusion Stochastic resonance using vibratory stimulus was more effective in the single leg stance task, rather than the double leg stance task. Moreover, sub-threshold vibratory stimulus(80%, 90%) intensity were more effective than higher vibratory stimulus(100%, 110%, 120%).
Purpose The purpose of this study is to identify why and how sports docudrama is one of the unique objects for the scholarship of sport history. Methods As a review study, this paper pays attention to, collects, and critically reviews three dimensions of the literatures: 1) ones that claim and argue for a-historicity of historical sport films by pointing out how they are full of actual errors, mistakes, and misrepresentation, and why they are problematic, 2) ones that belong to so called ‘the study of docudrama’ with specific focus on the themes of definition, mode of representation, and cultural memory, and 3) ones that attempt to envision the possibility of visual history or filmic history from the perspective of historiography and some other epistemological issues. Results Following the above review method, the result of this paper is also divided into three parts: 1) how sport historians respond to and criticize historical sport films from the sense based on the modern historiography, 2) how a group of historians argue why historical sport films can be one of the promising way of doing histories, 3) review of the study of docudrama, focusing on what is docudrama, why it can be a mode of representation, and how it resonates to cultural memory. Conclusions As a conclusion, this paper argues that a more collectively academic concerns to sport docudrama paves way for developing and envisioning the scholarship of sport history.
