| Abstract | OBJECTIVES: This study measured the neuromotor excitability and reaction time in professional and amateur Taekwondo (TKD) practitioners and compared them with non-athletes. DESIGN: A cross-sectional cohort study design. SETTING: Exercise laboratory setting. PARTICIPANTS: 40 TKD practitioners (20 professionals, 20 amateurs) and 20 non-athletes. MAIN OUTCOME MEASURES: Neuromotor excitability (rheobase), premotor reaction time (PRT), total reaction time (TRT) and electromechanical delay (EMD) of rectus femoris (RF) and flexor pollicis brevis (FPB) in response to audio and visual stimuli were measured. The professional TKD practitioners have shorter TRT than non-athletes with sport-specific visual stimuli but they have longer PRT and TRT in response to audio stimuli than the amateur practitioners and non-athletes. RESULTS: The professional practitioners have longer EMD than the amateurs in responding to audio (p = 0.032) and sports-specific visual stimuli (p = 0.03) in FPB. Professional practitioners have higher excitability in RF (p < 0.001) than the amateurs and non-athletes. CONCLUSION: We conclude that professional TKD practitioners have better neuromotor ability in both large and small muscles with faster reactions to sport-specific stimuli, suggesting a generalized training effect across muscles. They react slower to non-sport specific stimuli, which suggested a decreased sensitivity to irrelevant sensory inputs after intensive TKD training. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
