Because previous studies have suggested that there is a relationship between injury risk and inter-segment coordination, quantifying coordination between the segments is essential. Even though the midfoot and forefoot segments play important roles in dynamic tasks, previous studies have mostly focused on coordination between the shank and rearfoot segments. This study aimed to quantify coordination among rearfoot, midfoot, and forefoot segments during running. Eleven healthy young men ran on a treadmill. The coupling angle, representing inter-segment coordination, was calculated using a modified vector coding technique. The coupling angle was categorised into four coordination patterns. During the absorption phase, rearfoot–midfoot coordination in the frontal planes was mostly in-phase (rearfoot and midfoot eversion with similar amplitudes). The present study found that the eversion of the midfoot with respect to the rearfoot was comparable in magnitude to the eversion of the rearfoot with respect to the shank. A previous study has suggested that disruption of the coordination between the internal rotation of the shank and eversion of the rearfoot leads to running injuries such as anterior knee pain. Thus, these data might be used in the future to compare to individuals with foot deformities or running injuries. 相似文献

The dynamic field theory predicts that biases toward remembered locations depend on the separation between targets, and the spatial precision of interactions in working memory that become enhanced over development. This was tested by varying the separation between A and B locations in a sandbox. Children searched for an object 6 times at an A location, followed by 3 trials at a B location. Two- and 4-year-olds', but not 6-year-olds', responses were biased toward A when A and B were 9-in. and 6-in. apart. When A and B were separated by 2 in., however, 4- and 6-year-olds' responses were biased toward A. Thus, the separation at which responses were biased toward A decreased across age groups, supporting the predictions of the theory. 相似文献

Envisioning Equitable Classrooms That Enhance All Students’ Wonderful Ideas: A Duckworth Perspective
Suzanne M. Nesmith Jason F. Trumble Sarah J. Haugh-Villareal Kelsie S. Porter Megan A. Schaum Erin M. Spencer 《Journal of Latinos & Education》2014,13(3):238-239
This synopsis centers on Eleanor Duckworth’s ideas about the relationship between education and intellectual development. Specifically, Duckworth described the essence of intellectual development as the “having of wonderful ideas” and the essence of pedagogy as the creation of occasions to “have wonderful ideas.” As opposed to accepting the persistent, pernicious educational belief that there is a single, best way to understand and a single, best way of explaining this understanding, Duckworth determined that all children can come to comparable, equally satisfactory, wonderful understandings when provided occasions to do so. 相似文献
