Comparison of agility between the flat foot and normal foot in East Java']Java Puslatda athletes

Background: Flat foot, also known as pes planus, is a postural deformity characterized by the fall of the foot's arch, with all or almost all of the soles of the foot in contact with a flat surface. A flat foot is related to the function of the lower leg, increases the likelihood of sports injuries, and affects the motor abilities of the lower limbs. This study aims to compare the agility of the athletes of the East Java Puslatda with flat feet and normal feet. Method: This study is an observational retrospective study using the medical records of athletes who underwent sports injury risk screening at the Sports Clinic RSUD dr. Soetomo Surabaya. Subjects were divided into the flat foot and normal foot groups. The agility of both groups was measured using Agility T-drill test tools and compared between the two groups. Results: There were 46 subjects divided into 23 subjects in the flat foot group (14 males and 9 females aged 17-33 years) and 23 subjects in the normal foot group (12 males and 11 females aged 16-31 years). The average agility in the flat foot group was 11.23 +/- 0.19 seconds (9.62 seconds - 12.74 seconds), while in the normal foot group, it was 11.12 +/- 0.21 seconds (9.16 seconds - 13.38 seconds). There was no significant difference in agility between the two study groups. Analysis of each sport showed no significant difference in agility between the flat foot and normal foot groups. Analysis according to intrinsic factors showed a significant positive correlation with moderate strength between agility and gender. Conclusion: There was no significant difference in agility between athletes with flat foot and normal foot.
