Mechanical and mathematical model of external ballistics of the modern sport bow has been proposed. The force of air drag, shear friction, and drag on the fletching, and the additional force that depends on the angle of attack have been taken into account in the model. The corresponding Cauchy problem was stated and solved using the Runge-Kutta method and the program NDSolve from the software p...
There is evidence that the recall schema becomes more refined after constant practice. It is also believed that massive amounts of constant practice eventually leads to the emergence of especial skills, i.e., skills that have an advantage in performance over other actions from within the same class of actions. This advantage in performance was noticed when one-criterion practice, e.g., basketba...
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...
Abstract Objective: Considering the positions that the shooter take during shooting in different fiels, possibility of activity the deltoid and supraspinatus muscles which are common muscles during shooting, varies in different fields. Therefore, the purpose of the present study was to evaluation and compare the activity of deltoid and supraspinatus muscles between shooting fields. Methods: 2...
