The Effect of Sand Exercise Program on Knee Muscle Co-Contraction in Runners with Over Pronated Feet during Running |
|
| چکیده انگلیسی مقاله |
Background and Objectives: Over‑pronated feet (OPF) is a common abnormality of the foot. Sand can be changed lower limb muscle activities. Therefore, the aim of this study was to evaluate the effect of sand exercise program on knee muscle co-contraction in runners with over‑pronated feet. Materials and Methods: Thirty individuals (age range: 18–26 year) with OPF were randomly allocated in the equally sized control and experimental groups. Experimental group performed sand running exercise protocol during eight weeks. Muscle activities were recorded using electromyography system. Two variables including directed co-contraction and general co-contraction were calculated before and after training programs. Results: In the experimental group, lower directed vastus lateralis/vastus medialis co-contraction, greater general knee co-contraction and directed medial/lateral knee co-contraction during the mid-stance and push off phases were found at the post-test compared with the pre-test (p< 0.017). Irrespective of the time, greater medial/lateral knee directed co-contraction during the push off phase was observed in the experimental group compared with the control group (p=0.043). Conclusion: Sand can be used as functional training surface, as increased muscle co-activation is required to make postural adjustments and keep the body balanced. |
