Sensorimotor control in overarm throwing.
Goal-directed movement is possible because the cortical regions regulating movement have continuous access to visual information. Extensive research from the various domains of motor control (i.e., neurophysiology, neuropsychology, and psychophysics) has documented the extent to which the unremitting availability of visual information enables the sensorimotor system to facilitate online control...
متن کاملExploring the mechanism of skilled overarm throwing.
Although the kinematics and dynamics of overarm throws, such as baseball pitching, have been studied extensively, the relations between these measures remain largely unknown. This review uses a three-dimensional analysis to characterize the mechanical basis of skilled overarm throws by focusing on how each joint angular acceleration is produced by the muscle torques, gravity torques, and veloci...
متن کاملExamining impulse-variability in overarm throwing.
The purpose of this study was to examine variability in overarm throwing velocity and spatial output error at various percentages of maximum to test the prediction of an inverted-U function as predicted by impulse-variability theory and a speed-accuracy trade-off as predicted by Fitts' Law Thirty subjects (16 skilled, 14 unskilled) were instructed to throw a tennis ball at seven percentages of ...
متن کاملStroboscopic computerized determination of humeral rotation in overarm throwing.
Analysis of the final phase of the overarm handball throw was carried out by a microcomputerized treatment of photographic images taken simultaneously in two grid layouts. Reflective stickers on the joints of the throwing arm (shoulder, elbow, wrist) allowed the coordinates of these three points to be measured against a reference on the wall. Using a mathematical treatment and Euler matrices, t...
متن کاملEffect of specific resistance training on overarm throwing performance.
PURPOSE The main purpose of this study was to compare the effect of a specific resistance training program (throwing movement with a pulley device) with the effect of regular training (throwing with regular balls) on overarm throwing velocity under various conditions. METHODS The training forms were matched for total training load, ie, impulse generated on the ball or pulley device. Both trai...
