| Abstract | In sport activities and rehabilitation it is of great benefit to provide an autonomous and individual assessment system of motor activity. Providing quantitive data about the movement is not only valid for characterising the courses of training processes, it will also help the athlete to improve the technique or to enhance learning in motor rehabilitation. In this regard, significant features are required to monitor and score the movement-pattern. We analyzed different rowing parameters including grip pull out, grip force, slinding seat position and foot-rest force to derive relevant rowing features. An indoor rower was used to record several movement parameters of elite and novice athletes. Different features were extracted for each rowing parameter by assessing the difference of each feature value on elite and novice athletes. The most relevant features as well as rowing parameters were selected based on the signal-to-noise-ratio ranking. The efficiency of Naive Bayes classifier to differentiate the rowing activity between elite and novice athletes was investigated. According to the results five features are sufficient to achieve a high classification rate of 100%. Using the proposed feature set a grading system was introduced enabling to rank and score the quality related to motor activity in rowing. |

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.
