The relationship of some kinematic variables of approach and takeoff phases with accuracy and velocity of high spike in volleyball

Abstract

Research aims to:- Identify the values of some kinematics variables for two phases approaching and the takeoff of high spike in volleyball.- Identify the accuracy values of the spike in volleyball - Identify the relationship between some kinematic variables for both phases of the approach and take-off in volleyball- Identify the relationship between some kinematic variables for both phases of the approach and accuracy of high spike in volleyball.Scopes of research: The human scope: a sample of the players Nineveh province's volleyball Place scope: volleyball court in the indoor games hall in the sport Education College Mosul University The researcher used a descriptive method for it suitability for the nature of the research The research sample was selected and intentional which consisted of five players team representing the province of Nineveh volleyball, reaching mean age (21.333) years with a standard deviation (2.94) and who had previously training and practice . SPSS statistical software to extract statistical variables which were as follow: 1. The mean.2. Standard deviation.3. Coefficient of variation4 - Simple correlation coefficient (Pearson)The conclusionsThe ball throwing angle effect in the ball speed in spike- Arm rotation in a big angular velocity effect positively on the speed of the ball in smash beating in volleyballeffect positive the angle of trunk in speed of spike in volleyball
