Abstract The aims of this study were to talent transfer, rapidly develop, and qualify an Australian female athlete in the skeleton event at the 2006 Torino Winter Olympic Games and quantify the volume of skeleton-specific training and competition that would enable this to be achieved. Initially, 26 athletes were recruited through a talent identification programme based on their 30-m sprint time. After attending a selection camp, 10 athletes were invited to undertake an intensified skeleton training programme. Four of these athletes were then selected to compete for Australia on the World Cup circuit. All completed runs and simulated push starts were documented over a 14-month period. The athlete who eventually represented Australia at the Torino Winter Olympic Games did so following approximately 300 start simulations and about 220 training/competition runs over a period of 14 months. Using a deliberate programming model, these findings provide a guide to the minimum exposure required for a novice skeleton athlete to reach Olympic representative standard following intensified sport-specific training. The findings of this study are discussed in the context of the deliberate practice theory and offer the term “deliberate programming” as an alternative way of incorporating all aspects of expert development. 相似文献

The aim of the present study was to assess the influence of self-efficacy and past behaviour on young people's physical activity intentions using an augmented version of Ajzen's Theory of Planned Behaviour. We hypothesized that self-efficacy would exhibit discriminant validity with perceived behavioural control and explain unique variance in young people's intentions to participate in physical activity. We also expected that past physical activity behaviour would attenuate the influence of attitude, subjective norms, perceived behavioural control and self-efficacy on intention. The sample comprised 1152 young people aged 13.5 - 0.6 years (mean - s ) who completed inventories assessing their physical activity intentions, attitudes, subjective norms, perceived behavioural control, self-efficacy and past physical activity behaviour. A confirmatory factor analysis demonstrated that the constructs of the Theory of Planned Behaviour achieved discriminant validity. Furthermore, the measures of attitudes, subjective norms, perceived behavioural control and self-efficacy were significantly related to their respective belief-based measures, supporting the concurrent validity of the measures of the Theory of Planned Behaviour. A non-standard structural equation model demonstrated that attitude and self-efficacy were strong predictors of physical activity intention, but perceived behavioural control and subjective norms were not. Self-efficacy attenuated the influence of attitudes and perceived behavioural control on intention. Past behaviour predicted intention directly and indirectly through self-efficacy and attitude. The present findings demonstrate that young people with positive attitudes and high self-efficacy are more likely to form intentions to participate in physical activity. Furthermore, controlling for past physical activity behaviour revealed that the unique effects of self-efficacy and attitudes on young people's physical activity intentions were unaltered. 相似文献

ABSTRACTThe aim of this trial was to compare an eight-week individual movement quality versus traditional resistance training intervention on movement quality and physical performance. Forty-six trained adults were randomised to a movement quality-focused training (MQ) or a traditional resistance training (TRAD) group, and performed two individualised training sessions per week, for 8 weeks. Session-RPE (sRPE) was obtained from each session. Measures of movement quality (MovementSCREEN and Functional Movement Screen (FMS)) and physical performance were performed pre- and post-intervention. All measures improved significantly in both groups (3–14.5%, p = <0.005). The between-group difference in MovementSCREEN composite score was not statistically significant (0.3, 95% CI ?3.4, 4.1, p = 0.852). However, change in FMS composite was significantly greater in MQ (1.3, 95% CI 0.8, 1.8, p < 0.001). There were no significant between-group differences in physical performance (p = 0.060–0.960). The mean sRPE was significantly lower in MQ (5.25, SD 1.2) compared to TRAD (6.6 SD 1.0, p = <0.001). Thus, although movement quality scores were not distinctly greater in the MQ group, a movement quality specific intervention caused comparable improvements in physical performance compared to traditional resistance training but at lower perceived training intensity. 相似文献

This study examined British young people's understanding of the rights of asylum-seeking young people. Two hundred sixty participants (11-24 years) were read vignettes involving asylum-seeking young people's religious and nonreligious self-determination and nurturance rights. Religious rights were more likely to be endorsed than nonreligious rights. In general, younger participants were more likely than older participants to endorse the rights of asylum-seeking young people. Supporting a social cognitive domain approach, patterns of reasoning varied with the type of right and whether scenarios involved religious or nonreligious issues. Few developmental differences were found regarding participants' reasoning about asylum-seeking young people's religious or nonreligious rights. The findings are discussed with reference to available theory and research on young people's conceptions of rights. 相似文献

This study examined specific forms of emotional reactivity to conflict and temperamental emotionality as explanatory mechanisms in pathways among interparental aggression and child psychological problems. Participants of the multimethod, longitudinal study included 201 two‐year‐old children and their mothers who had experienced elevated violence in the home. Consistent with emotional security theory, autoregressive structural equation model analyses indicated that children’s fearful reactivity to conflict was the only consistent mediator in the associations among interparental aggression and their internalizing and externalizing symptoms 1 year later. Pathways remained significant across maternal and observer ratings of children’s symptoms and with the inclusion of other predictors and mediators, including children’s sad and angry forms of reactivity to conflict, temperamental emotionality, gender, and socioeconomic status. 相似文献

A highly touted feature of the so-called global “revolution” in higher education is the trend to use information technology
to reach a broader clientele. Although there is evidence that students may be learning the material in on-line courses as
well as in traditional face-to-face universities, how well students learn content is not the only reason they persist to a
degree, and student persistence is an important goal of higher education institutions. In this paper, we make the case that
the life conditions for students attending virtual universities are different from those of “traditional” students in face-to-face
universities, and that this difference puts a particular (largely non-pecuniary) premium on time to degree. With our data
from a Catalan virtual university, the Open University of Catalonia (UOC), we are able to test this hypothesis directly by
using the heterogeneous degree structure of the Catalonian/Spanish higher education system to estimate whether the number
of courses required to get various degrees (the length of the degree program) is significantly related to student persistence.
The study analyzes several cohorts of students (those who entered in 2000–2003) studying in the UOC and estimates the factors
that influence their degree completion. We find that the completion rate is generally low, but that students taking shorter
degree courses at the UOC are much more likely to complete their degrees. This suggests that, given their clientele, on-line
universities operate under very different constraints from their face-to-face counterparts. Our results are important for
higher educational researchers, who have mainly focused on younger populations attending face-face universities. They also
can serve university administrators who launch distance education degree programs and make high stakes decisions about them
with little of no information on the likely behavior of their older students, and can serve employers who are deciding whether
to subsidize their employees to take advanced degrees through on-line programs of study. 相似文献

This research investigates the effect of classroom explicitation of initial conceptions (CEIC) on conceptual change in the
context of learning electricity. Eight hundred and seventy five thirteen year-olds were tested in laboratory conditions to
see if CEIC is or is not a productive step toward conceptual change. All students experienced a problem-based pedagogical
treatment called “the electronic challenge.” The randomly determined experimental group was also exposed to CEIC. Data shows
a significant beneficial effect of CEIC and no unwanted “contamination effect”, particularly for female subjects. 相似文献

This paper addresses the economic returns on tertiary degrees obtained in ages above 30 for individuals with upper-secondary schooling in light of current ideas on lifelong learning. Sweden is a case in point: Swedish tertiary education is open to older students, and labor market legislation supports employees who take a leave to study. The longitudinal data used for this analysis is based on annual population level registers from 1981 to 2007. Matching techniques are combined with fixed effect estimation to account for non-random selection. Late degrees were found to increase the employment rate by 18 percentage points and earnings while employed by 12 percent, which indicates strong employment effects and small effects on earnings while employed. The effects were absent in the higher parts of the earnings distribution, and females gained more than men. The estimated effects are largely stable across periods within a birth cohort. 相似文献

First-year engineering students often complain about their mathematics courses as the significance of the difficult and abstract calculus to their field of study remains unclear. We report on the project MathePraxis, a feasibility study which was designed as a means to give first-year students some impression about the use of mathematics in real practice. We aim to increase the motivation and retention rates among engineering students by connecting the contents of the first-year mathematics lectures with practical applications. We developed three projects, two of which are described in this article: an inverted pendulum considered as a model for the automated control within a Segway and a study on the optimal design of a ribbed cooler. In this article, we briefly present the mathematical content of the projects and report on their implementation. 相似文献
