| Abstract | UNLABELLED: There is a paucity of research examining the 6-minute walk test (6MWT) in young to middle-aged healthy individuals, and little is known about the utility of the 6MWT for predicting aerobic fitness. PURPOSE: 1) To characterize the aerobic demand of the 6MWT in a group of healthy working-aged adults; 2) to examine the ability of the 6MWT to objectively differentiate the fitness level between participants; and 3) to create prediction equations for 6MWT distance and maximal oxygen consumption (VO2 max) using the 6MWT results in combination with easily measured anthropometric and demographic variables. METHODS: Participants (N = 44; men, 23; women, 21) completed the 6MWT, VO2 max, and a battery of simple fitness measures. RESULTS: The aerobic demand of the 6MWT was 28.7 ± 5.7 mL·kg(-1)·min(-1) (72.7% ± 11.6% of VO2 max). Rank order correlation revealed a moderate strength association between 6MWT distance and VO2 max (r = 0.49; P = 0.001). Using stepwise multiple linear regression, we were able to account for 72.4% of the variance in VO2 max using the 6MWT when combined with participant body weight, sex, resting heart rate (HR), and age according to the following equation: VO2 max (mL·kg(-1)·min(-1)) = 70.161 + (0.023 × 6MWT [m]) - (0.276 × weight [kg]) - (6.79 × sex, where m = 0, f = 1) - (0.193 × resting HR [beats per minute]) - (0.191 × age [y]). CONCLUSION: The 6MWT is of moderate-to-vigorous intensity, and may be useful in the classification of aerobic fitness, which is associated with health outcomes. Inclusion of further patient characteristics greatly increases the predictive value of the 6MWT for estimating VO2 max, which has important implications for those seeking a noninvasive and simple-to-use determinant of maximal aerobic power. |

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.
