In statistics, power is the probability of observing a significant effect given the statistical analysis, sample size, and the true effect size in the population. Recent evidence suggests that many studies in sports science and motor behavior have been underpowered to reliably detect the effects

Motor behavior research frequently involves proposing hypotheses and subjecting them to statistical tests. The probability that a statistical test will correctly reject the null hypothesis, conditional on a true effect of a given size and an accepted rate of false-positive results, is called power

Motor Behavior of Schoolchildren (AMBS), which assesses the quality and quantity of the physical affordances in the 6- to 10-year-old children microsystems. Specifically, we intend to validate the AMBS as a reliable tool to analyze the home (and its materials) and school environments, with the purpose

Our intention is to highlight some of the most significant and impactful empirical work conducted in the field and to highlight novel and emerging areas for future research. The task of identifying areas of study that have been the

-types have better athletic performance in the morning, measured by race times, than N- and E-types. The Grooved Pegboard Test is a suitable task for investigating the relationship between chronotypes and cognitive/motor behavior because it has both motor and cognitive demands ( Bryden & Roy, 1999 ; Bryden
Four types of motor behavior research that include special populations are described. These research areas are descriptive, program effectiveness, theory generalization, and theory construction. In addition, three levels of applied and basic research outlined by Christina (in press) are described and juxtaposed to the four types of motor behavior research. Current trends and potential areas of inquiry are highlighted in each. In particular, Christina’s Level 2 applied research is considered attractive for adapted physical activity researchers, as it is theory-driven with relevant tasks and fiinctional settings and may therefore contribute to a growing professional literature.

Physical activity participation of persons with disabilities might be enhanced by careful application of motor behavior research to instructional settings. However, it is argued that this research is not easily stated in terms that are useful to practitioners. The purpose of this paper is to examine the relationship between theoretical research and practice, and to suggest research strategies that will translate findings into helpful information for instruction. A number of applied research strategies are proposed, intended to gradually move from laboratory-inspired problems to issues applicable in typical instructional settings. These strategies include a clear conceptual rationale for including people with disabilities in the research, task modifications, a powerful initial study, replications, investigating interactions, conducting comparative studies, modifying the unit of analysis, generalization, and instructional considerations.

The effect of visuo-motor behavioral rehearsal (VMBR) training on tennis service performance during a tournament was investigated with 14 male tennis players. Seven participants were trained in relaxation I0 days before a major tournament, and then given a. relaxation and visualization audiocassette tape to use on a daily basis prior to the tournament. The visualization part of the tape led them to imagine themselves performing in their first tournament match, and guided them in repetitive practice on their serves. Seven other participants also competed in the tournament but did not receive the VMBR training. The higher ability training group achieved a marginally significant improvement in their percentage of good first serves, while the lower ability training group declined in their accuracy. Overall performance, as measured by their ratio of winners to errors, also favored the higher ability training group. Possible explanations of the results are discussed in terms of the interaction between the training program and the type of performer.
