Childhood Physical Fitness and Performance as Predictors of High School Sport Participation

ABSTRACT

Participation in youth sport is positively associated with physical fitness and performance. The purpose of the current study was to examine if physical fitness measures during childhood and early adolescence predicted high school sport participation. Participants included youth in the Michigan State University Motor Performance Study. Measures consisted of the endurance shuttle run, Wells sit-and-reach, jump and reach, standing long jump, agility shuttle run and 30-yard dash. Individual, generalized estimating equation models were used to estimate the association between each measure and the odds of participating in high school sport. For both sexes, the endurance shuttle run and agility shuttle run were related to sport participation. For boys only, the long jump and 30-yard dash were also associated with sport participation. Better physical fitness and performance across several dimensions in childhood, including those related to motor skills, enhanced the likelihood of sport participation in high school.  相似文献

The problems facing multidisciplinary teams: As perceived by team members     

Steven I. Pfeiffer 《Psychology in the schools》1981,18(3):330-333

The present study investigated the problems that team members perceive to exist on multidisciplinary teams. One hundred forty-seven team members on 40 teams from four urban school districts completed a questionnaire that presented an exhaustive listing of potential team problems. Results indicated that the two most pressing areas of concern for urban, multidisciplinary team members were: too constrictive a set of team roles and goals, and teams functioning under extensive pressure with minimal support. Strategies to reduce problems and enhance team functioning are presented.  相似文献   

A guide to McCarthy interpretation     

Jack A. Naglieri  Steven I. Pfeiffer 《Psychology in the schools》1982,19(1):18-23

The aim of the present study was to develop a system of tables to facilitate interpretation of the McCarthy Scales of Children's Abilities. Tables are presented that organize the McCarthy subtests according to Bannatyne's, Sattler's, and Meeker's systems of interpretation. In addition, tables that organize the McCarthy Scales into categories that reflect factors likely to influence various subtests are presented. These tables will provide a more structured approach to McCarthy interpretation and a straightforward empirical method for generating hypotheses regarding individual strengths and weaknesses in intellectual ability.  相似文献   

Special education placement decisions made by teams and individuals: A cross-cultural perspective     

Steven I. Pfeiffer 《Psychology in the schools》1982,19(3):335-340

The present study looked at whether special education placement decisions made by teams are superior to those made by individuals. The investigation was conducted in Puerto Rico to determine whether the benefits of the cooperative group process exist in another culture. Results indicated that teams in Puerto Rico generated significantly less variability (i.e., errors) in their placement decisions than did the same specialists acting independently.  相似文献   

The dynamic control ratio at the equilibrium point (DCRe): introducing relative and absolute reliability scores     

Tobias Alt  Axel J. Knicker  Heiko K. Strüder 《Journal of sports sciences》2017,35(7):688-693

Analytical methods to assess thigh muscle balance need to provide reliable data to allow meaningful interpretation. However, reproducibility of the dynamic control ratio at the equilibrium point has not been evaluated yet. Therefore, the aim of this study was to compare relative and absolute reliability indices of its angle and moment values with conventional and functional hamstring–quadriceps ratios. Furthermore, effects of familiarisation and angular velocity on reproducibility were analysed. A number of 33 male volunteers participated in 3 identical test sessions. Peak moments (PMs) were determined unilaterally during maximum concentric and eccentric knee flexion (prone) and extension (supine position) at 0.53, 1.57 and 2.62 rad · s^–1. A repeated measure, ANOVA, confirmed systematic bias. Intra-class correlation coefficients and standard errors of measurement indicated relative and absolute reliability. Correlation coefficients were averaged over respective factors and tested for significant differences. All balance scores showed comparable low-to-moderate relative (<0.8–0.9) and good absolute reliability (<10%). Relative reproducibility of dynamic control equilibrium parameters augmented with increasing angular velocity, but not with familiarisation. At 2.62 rad · s^–1, high (moment: 0.906) to moderate (angle: 0.833) relative reliability scores with accordingly high absolute indices (4.9% and 6.4%) became apparent. Thus, the dynamic control equilibrium is an equivalent method for the reliable assessment of thigh muscle balance.  相似文献
