Effect of Eight Weeks of Training on Artificial Grass, Natural Grass, and Synthetic Surface on Ankle Joint Co-Contraction during Running in Individuals with Over-Pronation
Running is one of the most popular physical activities in the world and is usually done on different surfaces. Different levels of running are associated with overuse injuries. Therefore, this study aimed to evaluate the effect of eight weeks of training on artificial grass, natural grass, and synthetic surface on ankle joint co-contraction during running in individuals with over-pronation. This study was designed as a double-blinded randomized controlled trial. Sixty participants aged 18–30 years with diagnosed excessive pronation of foot were randomly allocated into three intervention groups (natural grass, artificial grass, and synthetic surface) and a control group. Electromyography data during pre and posttest was collected using surface electromyography system. Results did not demonstrated and statistically significant between group differences in in directed and general ankle joint co-contraction (P>0.05). The results of the present study showed that the ankle joint co-contraction during training on three types of artificial grass, natural grass, and synthetic surfaces was not statistically different in individuals with over-pronation.
