Examining 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 کاملBrain activations underlying different patterns of performance improvement during early motor skill learning
BACKGROUND/INTRODUCTION Motor learning plays a central role in daily life and in neurorehabilitation. Several forms of motor learning have been described, among which motor skill learning, i.e. reaching a superior level of performance (a skill) through a shift of the speed/accuracy trade-off. During the first stage of learning a visuomotor skill, we observed differential patterns of evolution o...
متن کاملSpeed and accuracy of saccadic eye movements: characteristics of impulse variability in the oculomotor system.
Dynamic characteristics observed in the trajectories of saccadic eye movements reveal systematic variability of the force pulses used to move the eyes. This variability causes saccades to exhibit a linear speed-accuracy trade-off: As the average distance and duration of saccades toward specified target points increase, the standard deviations of saccadic-movement endpoints increase linearly wit...

متن کاملEffect of skill level on variability of intra limb coordination and control variables in top spin strike
The purpose of this study was to examine the effect of skill level on variability of intra limb coordination and control variables in top spin strike. The 16 participants of this study were divided into two groups of Skilled and Novice. The Skilled group was consisted of players who ranked as 8 top in national ranking at their age stage and the Novice group was consisted of players who rece...
