Abstract: (94 Views)
Introduction: A return to running after anterior cruciate ligament reconstruction (ACL-R) is critical to clinical success. The purpose of this research was to examine the effect of training on sand on the contraction of ankle muscles in people with pronated feet and with anterior cruciate ligament reconstruction during running.
Methods: The current research was a semi-experimental and applied study. Using G-Power software, the minimum sample size of 14 people was estimated for each group. The statistical sample of this research consisted of 28 teenagers from Ardabil province with an age range of 22 to 25 years. Biometric Ltd.'s 8-channel surface electromyography signals were recorded with a sampling rate of 1000 Hz.
Results: The obtained results showed that ankle general co-contraction was greater in the experimental group compared to the control group during the loading phase (P=0.001; d=0.363). Also, general co-contraction was greater in the experimental group compared to the control group during the push-off phase (P=0.001; d=0.363).
Conclusion: According to the obtained results, it was found that the general ankle co-contraction was altered in people with anterior cruciate ligament reconstruction and pronated foot in the running phase. However, more studies are needed to better confirm this.
