| Abstract | The goal of this project was to determine whether landing with a straightened or a bent knee during walking generates higher loads in the knee. Seventeen subjects, 11 males and 6 females, were videotaped while racewalking across a force plate. A goniometer was used to measure the flexion angle of the knee; gross muscle activities of the quadriceps and the hamstrings were measured using surface EMG. The measured ground force and accelerations of the tibia and the feet were substituted into a mathematical model to determine the knee contact force. The results indicated that the straight leg landing caused a higher contact force in the knee for novices, while the bent knee style produced a higher ground reaction force. However, experienced racewalkers did not exhibit the increased knee load; proper form kept their vertical accelerations small. |

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.
