| Abstract | The effect of body posture (e.g., gravity) on circulatory responses to exercise remains to be clarified. This study was designed to examine cardiovascular dynamics during prone swim bench exercise in age-group swimmers and to compare these responses to those of matched non-athletic children. Fourteen trained swimmers (mean age 11.3+/-0.5 years) performed progressive exercise to exhaustion during simulated butterfly stroke exercise on a swim bench. Stroke volume was assessed by the Doppler ultrasound technique. Standard echocardiographic measures of left ventricular dimensions and function were recorded at rest prior to exercise. Swimmers were compared to a group of 11 non-athletic children matched for age, gender, and anthropometric measures. Compared to the nonathletes, the swimmers demonstrated larger resting left ventricular diastolic dimension and mass (adjusted for body size) but no differences in systolic or diastolic function. Mean peak VO(2) was 23.2+/-4.1mlkg(-1)min(-1) and 17.8+/-4.4mlkg(-1)min(-1) in the swimmers and nonathletes, respectively (p<0.05). No significant changes were seen in stroke index with increasing work in either group, with values consistently greater in the swimmers (peak 37+/-6mlm(-2) versus 31+/-5mlm(-2) in the untrained subjects). Failure of stroke volume to rise during a progressive simulated swim test is consistent with a model of peripheral facilitation of circulatory responses to exercise. |

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.
