This study investigated the validity and reliability of the GymAware PowerTool (GPT). Thirteen resistance trained participants completed three visits, consisting of three repetitions of free-weight back squat, bench press, deadlift (80% one repetition maximum), and countermovement jump. Bar displacement, peak and mean velocity, peak and mean force, and jump height were calculated using the GPT, a three-dimensional motion capture system (Motion Analysis Corporation; 150 Hz), and a force plate (Kistler; 1500 Hz). Least products regression were used to compare agreeability between devices. A within-trial one-way ANOVA, typical error (TE; %), and smallest worthwhile change (SWC) were used to assess reliability. Regression analysis resulted in R2 values of >0.85 for all variables excluding deadlift mean velocity (R2 = 0.54–0.69). Significant differences were observed between visits 3-2 for bench press bar displacement (0.395 ± 0.055 m; 0.383 ± 0.053 m), and deadlift bar displacement (0.557 ± 0.034 m; 0.568 ± 0.034 m). No other significant differences were found. Low to moderate TE (0.6–8.8%) were found for all variables, with SWC ranging 1.7–7.4%. The data provides evidence that the GPT can be used to measure kinetic and kinematic outputs, however, care should be taken when monitoring deadlift performance. 相似文献

Clinical medical journals have not been effective in meeting the information needs of practitioners and bridging the gap between clinical research and practice. The slow adoption of results of clinical research is at least partly due to the failure of clinical journals to disseminate information in a way that would motivate practitioners to change practice. Although implementation is primarily a local process, medical journals are in a unique position to advance implementation by modifying their focus and adjusting their contents. Strategies that may be useful include publication of pre‐appraised evidence summaries and ‘clinical bottom‐lines’ and giving importance to systematic reviews and large evaluative research articles as they represent higher levels of evidence and have greater potential to change practice. Clinical journals should encourage researchers to consider how and by whom the findings will be used and provide information on implications for implementation such as possible strategies that may work, cost‐effectiveness, side‐effects and potential barriers to implementation. Medical journal publishers should explore ways to cooperate so that findings of landmark clinical trials could be shared thus reducing the ‘scatter’ of medical information. Electronic media offers numerous advantages such as quick accessibility and linking of information, and medical journals should capitalize on such innovations. There is a paradigm shift in health care practice as evidence is consciously and explicitly incorporated into individual patient care. Medical journals need to change to reflect this change in practice and provide practitioners with valid and relevant information. 相似文献

This paper considers what early years practitioners need to know about bilingual acquisition. It argues that bilingualism is not only an asset in the classroom and the community, but also an individual and family achievement that requires commitment and determination. The different contexts of bilingual acquisition are considered, along with the implication for a successful outcome. In particular, given our current understanding of the processes of language acquisition, the role of the input in each of the two languages will be discussed; the implications of this for early years teachers/practitioners are also considered in order to find the most effective ways of supporting bilingual development in the classroom. 相似文献

Preschool children's reasoning about ability 总被引：3，自引：0，他引：3
Young children's reasoning about ability was investigated among 155 preschoolers (M = 4 years, 10 months) across 3 studies. Results suggest that preschoolers are sensitive to mental state information when making judgments about another child's ability: They judged a child who finds a task easy to be smarter than one who finds the same task hard. Systematic patterns of errors on recall tasks suggest that preschoolers perceive positive correlations between (a) exerting effort and experiencing academic success, and (b) being nice and having high academic ability. Results from a comparison group of forty 9- to 10-year-olds (M = 9 years, 10 months) suggest that the preschool findings generally reflect emerging patterns of reasoning about ability that persist into later childhood, but that the perceived correlations between high effort and academic outcomes and between social and academic traits diminish with age. 相似文献

Providing interlibrary loan service to K–12 schools is investigated in this article. Request analysis of a university interlibrary loan service to schools is presented along with a survey of those schools’ use of the service. Results from a survey of other libraries that provide similar loan services to schools are also presented. A lengthy literature review of interlibrary loan for K–12 schools places modern offerings in an historical perspective. 相似文献

European education ministers and officials signed a Bologna Declaration with a goal to reform, strengthen, and standardize higher education programs and degree structures by 2010. Graduates will become more mobile and marketable to employers throughout Europe. These programs shall also attract students worldwide. Higher education programs on other continents have taken notice and are in the process of initiating similar goals and outcomes. All of these events are creating new research opportunities for academic business librarians in all aspects of library support and services including collection development, reference, and instruction. 相似文献

ABSTRACT This study compared the effects of dictating load using individual (ILVP) or group (GLVP) load-velocity profiles on lower-body strength and power. Nineteen trained males (23.6 ± 3.7 years) completed a back squat one-repetition maximum (1-RM), load-velocity profiling (LVP), and countermovement (CMJ), static-squat (SSJ) and standing-broad (SBJ) jump tests before and after 6 weeks of resistance training. Participants were randomly assigned to an ILVP, or GLVP intervention with intra-session load dictated through real-time velocity monitoring and prediction of current relative performance using either the participant’s LVP (ILVP) or a LVP based on all participant data (GLVP). Training resulted in significant increases in back squat 1-RM for the ILVP and GLVP group (p < 0.01; 9.7% and 7.2%, respectively), with no group-by-time interaction identified between training groups (p = 0.06). All jump performance significantly increased for the ILVP group (p < 0.01; CMJ: 6.6%; SSJ: 4.6%; SBJ: 6.7%), with only CMJ and SSJ improving for the GLVP group (p < 0.05; 4.3%). Despite no significant group-by-time interaction across all variables, the ILVP intervention induced a greater magnitude of adaptation when compared to a GLVP approach. Additionally, an individualised approach may lead to greater positive transfer to power-based movements, specifically vertical and horizontal jumps. 相似文献
