Parameters of the multiple regression equation were then used to calculate and determine the thickness and hardness between the different types or synthetic tracks. The results may be used by manufacturers to developed and obtain IAAF approval. There were 106 specifications in this research. The material test had force reduction and vertical deformation. All the dates were calculated using the Pearson's Product moment Correlation and multiple regression analysis. The parameters were then optimally allocated in accordance with the track surfaces. The results of this study indicated that synthetic rubber tracks design for force reduction (FR) should be focused on top and bottom hardness, for vertical deformation (StV), should focus on top of hardness. It maybe worth pointing out that we obtained two regression formulas to determine FR and StV under the experiment limits of this research detailed accounts of the formulas are given below: I.FR=56.210-0.397*top of hardness+1.038*bottom of thickness*0.998*top of thickness-0.359*bottom of hardness II. StV=4.081-0.038*top of hardness+0.045*top of bottom-0.018*bottom of hardness+0.036*top of thickness. Therefore, this study can be used as a reference for future synthetic rubber track designs, enabling manufacturers to develop and obtain IAAF approval.
