The design of comparative study for long-pile artificial turf : Research on the dimate difference between Sendai College and Osaka University of Health and Sports Scienes

The purpose of this study is to research on the climate difference of long-pile artificial turf. The use of the long-pile turf has been under 15 years and the life span of the turf has not yet to come. The manufactures are doing experiment research indoor, however the research on the actual field has not yet done. Therefore this study has a chance to prove the result from the indoor experiment. Osaka University of Health and Sports Sciences has competed their work on the turf 16 month before Sendai College's work. They also examined the turf surface or performance change after their completion. Therefore we decided to compare the difference of change in climate by using same tests that they have used in their study. The specific tests that we used were followed. 1) Shock absorption performance test 2) Polishing performance test 3) Shoes traction test As a result, the difference was not found, however the data as of now is only from two times, so there is a possibility that the data size was too small. The result might have change due to the influence of the unique weather change, such as snowfall, freezing, midsummer days etc. Even though the difference was not found from different weather conditions, many comparable designs can be used. For example, there could be a new design to find out the user's feeling of two different weather conditions in summer and winter, if there is no difference in change of years or quality of those two places. This study is limited to report the mid result of this comparative study until now and written to be the reference of the next expanded design research information.
