By increasing the demolition of old concrete structures and the interest of civil industries to consume cheaper materials, using Recycled Concrete Aggregate (RCA) can cause environmental protection and decrease the construction costs. On the other hand, the high potential of Recycled Aggregate Concrete (RAC) in concrete industry was established by extensive experimental researches were performe...

Purpose: Core stability and leg stiffness are two determinant mechanisms in athletic performance and risk injury. This study aimed to investigate the gender differences and relationship of these two factors in athletes. Methods: In this cross-sectional study, core stability and leg stiffness of 12 male and 12 female Iranian squash players at national level were examined utilizing McGill’...

Purpose: A theory states that strong core stability allows athletes to fully transfer forces from the upper extremities to lower extremities, and finally to the ground. On the contrary, weak core stability causes alterations in transferring forces, reduces sport performance, and increases risk for injury, especially in the lower extremities. Therefore, the current study investigated the relatio...

Purpose: Most studies have examined the effect of stretching and strength exercises on the glenohumeral joint (shoulder joint), on the other hand, due to the importance of the relationship between core stability and pectoral girdle, especially in archery athletes, the aim of this study was to investigate the effect of six weeks of core stability exercises on the glenohumeral joint internal rota...

This study investigates the reinforcement correction factor of concrete core in more detail to prepare appropriate outlines for interpretation of results. This investigation aims to minimize uncertainties involved to carry out the more realistic condition assessment of suspect buildings before taking up retrofitting/strengthening measures. For this purpose, an extensive experimental program inc...
