TEST-RETEST RELIABILITY OF PAIRED PREFERENCE TEST FOR THE WEIGHTED SHOES

The purpose of this study was to examine the test-retest reliability of paired preference test for the weighted shoes. Forty participants were recruited and instructed to put on the weighted shoes and choose the preferred one after completing four paired comparisons. During the tests, participants were blind of any information from the shoes. All the participants were invited to repeat the same procedure one week after the first session. The results in first session showed that thirty-two (80%) out of the forty participants preferred Shoe D or E, which centre of mass was close to the rear end of the shoe. The greater intra-class correlation coefficient (ICC=0.81) represents the perfect test-retest reliability of the paired preference test. The test protocol designed in this study could apparently reduce the numbers of the paired comparison under the characteristic of the testing shoe varied systematically, for example the weighted shoes used in this study

Multicolored parallelisms of Hamiltonian cycles

AbstractA subgraph in an edge-colored graph is multicolored if all its edges receive distinct colors. In this paper, we prove that a complete graph on 2m+1 vertices K2m+1 can be properly edge-colored with 2m+1 colors in such a way that the edges of K2m+1 can be partitioned into m multicolored Hamiltonian cycles

PREFERENCE TEST OF THE WEIGHTED SHOES

The purpose of this study was to use paired comparison approach to test the weighted shoe preference of the subjects. Forty subjects were recruited to put on five different weighted shoes and choose the preferred one after completing four paired comparisons. During the test, subjects were blind of any information from the shoes. The results showed that thirty-two (80%) out of the forty subjects preferred Shoe D or E, which centre of mass was close to the rear end of the shoe. Significant difference was found in shoe preference between the males and females (?24=10.500, p=.033), while was not found between the lighters and heaviers (?24=5.583, p=.233). The mechanism of the gender effect on the preference decision are unclear. The results of the weighted shoe preference test could be applied to athlete training or rehabilitation shoe design to be comfortable for the users
