Effects Of Kinesio-taping On Maintaining Medial Foot Arch Stability Of College Students During Running

Objective Currently,long-distance running is a popular.The damage it caused has become a problem that cannot be ignored.Among those injuries,the lower limb musculoskeletal system injuries are most common.A well-structured and functional foot arch can provide good cushioning to the ground's reaction force and reduce the incidence of lower limb injuries.Previous studies have found that there is a static increase in pronation of the foot after long-distance running,and excessive or prolonged pronation of the foot is considered to have a correlation with damage to the joints of the lower limbs.However,changes of foot arch stability during running are still unknown.kinesio-taping on foot arch has been widely used in clinical and sports training,and related research has proved that it can lift the static foot arch.However,there is no empirical study on whether kinesio-taping can promote the maintenance of arch stability during long-term exercise such as jogging.The purpose of this study was to investigate the changes in arch stability before and after running,and to explore the effect of kinesio-taping on the maintenance of arch stability during running,and to analyze the effects of running and kinesio-taping interventions on lower limb kinematics and kinetics changes.Methods This study used a crossing self-controlled study design.Eighteen healthy college students with long-distance running habits were recruited,and the subjects were randomly to have a 15-minute low-speed run with Kinesio-Taping(KT)or No-Taping(NT)intervention for the first time.After one week,the Kinesio-Taping interventions were different for the subjects.The subjects who received the No-Taping intervention test for the first time,had the Kinesio-Taping running test.The subjects who received the Kinesio-Taping intervention test for the first time,had the No-Taping running test.During both running trials,VICON 3D motion capture system and BERTEC gait analysis running platform were used to collect kinematics and kinetics data,and calculating the dynamic medial longitudinal arch(MLA)angle.Statistical level of significance was set at 0.05.Results(1)Under NT condition,compared with before running,the step-on medial longitudinal arch angle increased significantly after running(P <0.05),the difference between the maximum and step-on of MLA angle decreased significantly(P <0.05);(2)Under KT condition,there is no significant difference between the before and after step-on medial longitudinal arch angle,and there is no change in the difference between the maximum and step-on of MLA angle;(3)In NT,at the end of running,the peak angle of the ankle inversion increased significantly during stance phase(P <0.05),the ankle plantar flexion moment decreased significantly(P <0.05);(4)In KT,at the end of running,there were no significant changes in the peak angle of ankle inversion and the peak plantar flexion moment;(5)Under both with or without conditions,during the support phase at the end of running,the peak angles of hip extension were significantly decreased(P <0.05)and the peak angles of hip adduction were significantly increased(P <0.05).Conclusion(1)Under NT condition,after 15 minutes low-intensity running,the stability of arch decreased on step-on phase,and the foot mobility during the step-on phase to the full support period decreased;(2)KT has the effect of maintaining the angle of the medial longitudinal arch on stepon phase and maintaining the dynamic stability of the arch after running,KT has a positive effect on maintaining the foot mobility during the step-on phase to the full support period.(3)KT can reduce the peak angle of ankle inversion after running and maintain the pedaling moment,improve the stability of ankle joint.
