function is an integral factor for injury risk in sport. A previously concussed athlete with residual deficiencies in processing environmental stimuli and task constraints, along with the inability to preplan correct motor sequences, may not be able to produce protective muscular forces, thus leading to

coordination were major predictors of agility performance. Two-legged side jumps seem to be an influential component of agility, and this may be because of the similarity between the task constraints. The 2-legged side jumps required getting over a wooden plank repeatedly over time in a constraint area and

—with the possibility of relative contributions of each lying anywhere along a continuum between the two, depending on the task constraints. Error endpoint distributions typically have an elliptical shape with the orientation of the long (primary) axis indicating the primary direction of error. A primary

. Discussion There are four major results from this study of paced rhythmic lateral stepping in healthy adult subjects. First, CM motion was found to be dependent upon task constraints, namely pacing frequency. It appears modifications to CM motion serve to preserve stepping and avoid delays in stepping that

, a by-product of a movement where temporal precision was not the primary goal. The apparent temporal regularity instead results from the influence of environmental, organism, and task constraints acting on the unfolding movement ( Thelen, 1991 ; Viviani & Laissard, 1991 ). The former class of

Several players recalled situations in which they had adapted their preparation in response to changing task constraints such as unexpected weather condition or an acquired shot shape.
