This study investigated the influence of perceptual training on
volleyball serve-reception performance. The subjects were ten female high-school
volleyball players. Subjects were randomly assigned in equal
numbers to a control or an experimental group.
Both groups were tested on two occasions, prior to and following a
three-week perceptual training intervention....
Individuals with Senile Dementia of the Alzheimer Type (SDAT) are up to four times more likely to sustain an accidental fall than their non-demented peers. The cause(s) of this elevated risk, however, has not been determined. Prior to the design of balance retraining programs, researchers need to uncover the nature...
This experiment was conducted to study the effects of three different forms of visual knowledge of results (KR) on maximal strength output in isokinetic exercise. The task used was an isokinetic extension of the knee, followed by a corresponding flexion. Four, six-subject experimental groups completed four testing sessions conducted over...
This study investigated the relative effectiveness of
three instructional strategies on the learning of an overarm
throw among preadolescent females. Subjects were randomly
assigned to one of the following instructional strategies:
a correct model supplemented with verbal cues, a learning
model supplemented with verbal cues, and verbal cues only.
The...
In competitive swimming a spread in time of only 0.10,
and 0.16 seconds constituted the difference between
finishing second and seventh, and first and eighth,
respectively, in the women's 50 yard freestyle at the 1993
NCAA Division III National Swimming & Diving Championships.
Based on data collected over a period...
Although research evidence clearly indicates support surface properties are a major factor contributing to fall risk among the elderly, investigations examining the influence of variations in surface conditions on the postural control of older adults during task performance have been limited. Thus, the primary purpose of the present studies was...
For coaches to qualitatively analyze the performance of sport skills as executed by their
students, they must possess an internal image of the desired skill against which to make
comparisons (Hoffman, 1983; Pinheiro & Simon, 1992). Leas and Chi (1993) have
indicated that there are differences between novice and expert...
