Mechanical work and muscular efficiency in walking children.
The effect of age and body size on the total mechanical work done during walking is studied in children of 3-12 years of age and in adults. The total mechanical work per stride (W tot) is measured as the sum of the external work, W ext (i.e. the work required to move the centre of mass of the body relative to the surroundings), and the internal work, W int (i.e. the work required to move the li...

proficiency level and factors fostering reticence in efl learners
according to cheng (1999), in recent esl/efl literature, asian (especially east asian) learners of english as a foreign/second language have been arguably reported as reticent and passive learners. the most common allegations are that these students are reluctant to participate in classroom discourse; they are unwilling to give responses; they do not ask questions; and they are passive and over...

This study aims at correlate Wmec and Cr with Eff. Twelve healthy men volunteered in the study. Wmec and Cr were measured during a treadmill running test which consisted in a rest period, incremental warm up and running test at 10km.h -1 . The biomechanical data, rest oxygen consumption (VO2) and exercise VO2 data were obtained. Relationships between variables were investigated using Pearson’s ...
متن کاملIdealized walking and running gaits minimize work
Even though human legs allow a wide repertoire of movements, when people travel by foot they mostly use one of two locomotor patterns, namely, walking and running. The selection of these two gaits from the plethora of options might be because walking and running require less metabolic energy than other more unusual gaits. We addressed this possibility previously using numerical optimization of ...
