WitrynaThe finding of a VATO opposes a popular theory in motor control, the impulse-variability theory. This theory suggests that movement variability increases linearly with force production up until 65% of maximum force, at which point a linear decrease in movement variability is observed to maximum force (Sherwood & Schmidt, 1980; ... WitrynaThe lower variability in speed for accurate free throws than for short-range shots may be linked to shooters maintaining ground contact during free throws. This suggests that the impulse generated during the shot should be minimised. In contrast to absolute variability, the relative variability of all shots tends to decrease along

Witryna-Less than 300ms is an open-loop process -Greater than 300ms for MT is closed-loop Briefly describe what the speed-accuracy trade-off entails. -In general: increased speed leads to decreased accuracy -However: the trade-off is specific to the goal and nature of the movement How can the goal of a movement be differentiated? WitrynaThis study examined variability in kicking speed and spatial accuracy to test the impulse-variability theory prediction of an inverted-U function and the speed-accuracy trade-off. Twenty-eight 18- to 25-year-old adults kicked a playground ball at various percentages (50-100%) of their maximum speed … Witrynathis theory isn't great for fast, ballistic movements at all. intermittent control.
