Abstract

PURPOSE
The purpose of this study was to determine the factors related to cognitive comfort on tennis shoes which recorded the highest selling quantity of the single sports events.
METHOD
Subjects in this study were 10 male college tennis players with normal foot and no injuries in lower extremities. Five tennis shoe brands were used to test cognitive shoe comfort and the highest and lowest. Cinematography, force platform, and in-sole pressure distribution measurement system were used to analyze the lower extremity motion while running at the speed of 4m/sec.
RESULT
Rearfoot control variables and impact absorption variables were not shown statistically significant differences between comfort shoe and discomfort shoe. Torsion angle of discomfort shoes was significantly larger than comfort shoes(p<0.001). Regional average peak pressure of comfort shoes showed was shown to be larger than discomfort shoes in forefoot region and rearfoot region. Regional average peak pressure in M1, M3, M4, M6 was shown a statistically significant difference between comfort shoes and discomfort shoes(p<0.05). 1st phase and 2nd phase of the regional peak pressure were appeared to be larger in discomfort shoe than in comfort shoes.
CONCLUSION
It was suggested that increases in most of rearfoot control variables, impact force variables and pressure distribution variables may have been related to a decrease in perceived comfort. On the contrary, few findings of this study were decreases in comfort shoes. Therefore, future study for examining the relationship between comfort shoes and injury possibility should be followed.
