Abstract
Introduction: Today, disabled sports have become one of the most important categories in the world of sports. In the meantime, exercising the blind and visually impaired is essential. Therefore, the present study aimed to examine the effect of clothing weight on the range of lower limb muscle activities during the execution of archery skills in blind people.
Methods: The current research is semi-experimental and laboratory-type. The statistical sample of the present study included 30 blind boys from Ardabil City who were selected purposefully and voluntarily. The subjects were randomly divided into two groups. The shooting target was placed at a distance of 10 meters from the subject. A two-way analysis of variance and a t-test at a significance level of 0.05 were used for statistical analysis of the data.
Results: According to the obtained results, the effect of the time factor on the electrical activity of the vastus medialis muscle when releasing the bowstring was statistically significant. The impact of the group factor on the electrical activity of the tibialis anterior muscle when releasing the bowstring had a statistically significant difference. Also, the effect of the group factor when taking the bow in the rectus femoris muscle and biceps muscle had a statistically significant difference.
Conclusions: Finally, according to all the obtained results, it can be said that probably using shooting clothes by affecting the electrical activity of the muscles of the lower limbs can improve balance during shooting, which can be one of the influential reasons, and become efficient in the success of archers.

Abstract
Introduction: Using treatment interventions in patients with anterior cruciate ligament (ACL) are essential. Also, some studies have reported that medical insoles decrease the rate of incidence of ACL injury. Therefore, the objective of this study was to investigated the acute effect of short-term anti-pronation insoles on foot pressure variables in individuals with anterior cruciate ligament reconstruction with pronated feet during running.
Methods: The present study was a semi-experimental type that was done at 2022 in Ardabil city. The sample of this study consisted of 13 individuals with both ACLR and pronated foot aged 23.4±2.5 years and 13 healthy ones aged 22.9±4.1 years that was selected with available sampling method. Plantar pressure values were recorded during running with and without anti pronated foot orthoses by foot scan device (sampling rate: 300 Hz). Two-way analysis of variance with repeated measures was used for statistical analysis.
Results: Results of the present study demonstrated a decreasing of peak plantar pressure variables on first (P=0.044), second (P=0.010), and fifth metatarsal (P=0.027) regions after using anti-pronated insoles during running stance phase.
Conclusions: Overall, it could be stated that foot orthoses possibly reduced plantar pressure and ground reaction force variables after anterior cruciate ligament reconstruction in individuals with pronated feet during running. However, further study is needed to better establish this issue.
