ABSTRACT

Water polo players require a high level of upper-extremity strength, flexibility and coordination to achieve a peak level of throwing performance. Increased levels of shoulder proprioceptive acuity, strength and range of motion (ROM) have been previously associated with higher sporting performance. A coach-rating scale, used to quantify an athlete’s kicking proficiency in soccer; was adapted in the current study to measure each coach’s subjective expert opinion regarding athletes’ throwing mechanics, velocity, and accuracy. To examine this hypothesis shoulder proprioception acuity of 18 water polo players was measured both in-water and on-land using an AMEDA apparatus and correlated with coach-rated throwing performance and clinical measures of shoulder strength and ROM. There was a moderate positive correlation between the in-water and the on-land proprioception acuity (r = 0.47, p < 0.05). The in-water score showing a strong positive correlation with coach rated throwing mechanics (r = 0.68, p < 0.05) and velocity (r = 0.75, p = 0.02), suggesting that superior proprioception acuity contributed to fast, mechanically-efficient throwing. These findings support the notion that in-water proprioceptive acuity is an important determinant of the throwing performance achieved by water polo athletes and its measurement may be a valuable adjunct to current athlete screening.  相似文献

The purpose of this study was to determine if a difference in interleukin-6 (IL-6) and delayed onset muscles soreness (DOMS) exists in two different phases of the menstrual cycle. Nine runners performed one 75-min high-intensity interval running session during the early follicular (EF) phase and once during the midluteal (ML) phase of the menstrual cycle. Estrogen and progesterone levels were significantly reduced in the EF phase when compared to the ML phase. IL-6 levels increased from pre- to postexercise in the EF and ML phases (p < .001). There was no relationship between the IL-6 level and DOMS. The results suggest that menstruating female runners need not vary training throughout the month to reduce DOMS.  相似文献

School size is becoming an increasingly important factor in discussions concerning school effectiveness, particularly those concerning cost‐effectiveness. Unfortunately, the term ‘small‐school’ is used in several different ways and lacks clarity. This paper examines the present usage of this term in order to construct a definition that could be incorporated into effectiveness research design.  相似文献

ABSTRACT

The year 2015 was significant for the arena of international development, as UNESCO’s Education for All agenda was replaced by Education 2030, which would identify minimum standards of education quality. The OECD had been working on extending its existing PISA assessment into low- and middle-income countries through PISA for Development (PISA-D) and positioned the new assessment as a means of tracking progress on the post-2015 goals. The organisation maintains that PISA-D was introduced primarily in response to the demands of the international community, especially low- and middle-income countries, and that the assessment was developed in partnership with them. This paper investigates those claims through an analysis of the arrival of PISA-D in Cambodia, situating the analysis within UNESCO’s shifting agenda and the strategic visions of the OECD and World Bank that first emerged in the 1990s. The result is a very different picture to the portrayals of local agency, demand, consensus and partnership that adorn the official websites and pamphlets of global agencies and much academic research, raising serious doubts about education governance post-2015.  相似文献

Intervention researchers often use curriculum‐based measurement of reading fluency (CBM‐R) with a brief experimental analysis (BEA) to identify an effective intervention for individual students. The current study synthesized data from 22 studies that used CBM‐R data within a BEA by computing the standard error of measure (SEM) for the median data point from the baseline and intervention data. The median CBM‐R score from the intervention that the authors of each study identified as most effective fell within the SEM (68% confidence interval) of the baseline data approximately 30% of the time, but the ranges for the two author‐identified most effective interventions overlapped over 75% of the time. Extended analyses were consistent with the BEA results for approximately three‐fourths of the instances after considering the SEM of the baseline and intervention phases. Using matched passages did not improve the overlap of the ranges, but there was less overlap when the study used three data points per condition. Results emphasize the importance of considering SEM of CBM‐R data when comparing interventions within a BEA. Further implications for practice and future research are included.  相似文献

The principal opportunities awaiting the Trump administration in K–12 education are only loosely related to the candidate’s campaign comments about advancing school choice and reducing the federal Education Department. Recent passage of the Every Student Succeeds Act signals that Congress will be loath to re-open the major federal K-12 programs for amendment. Bright opportunities away in connection with the Perkins Act, special education and the Institute of Education Sciences (IES), as well as various domains--beginning with the Office for Civil Rights--that beg for strategic deregulation.  相似文献

This study compared the efficacy of two cardiac anatomy teaching modalities, ultrasound imaging and cadaveric prosections, for learning cardiac gross anatomy. One hundred and eight first-year medical students participated. Two weeks prior to the teaching intervention, students completed a pretest to assess their prior knowledge and to ensure that groups were equally randomized. Students, divided into pre-existing teaching groups, were assigned to one of two conditions; "cadaver" or "ultrasound." Those in the cadaver group received teaching on the heart using prosections, whereas the ultrasound group received teaching using live ultrasound images of the heart. Immediately after teaching, students sat a post-test. Both teaching modalities increased students' test scores by similar amounts but no significant difference was found between the two conditions, suggesting that both prosections and ultrasound are equally effective methods for teaching gross anatomy of the heart. Our data support the inclusion of either cadaveric teaching or living anatomy using ultrasound within the undergraduate anatomy curriculum, and further work is needed to compare the additive effect of the two modalities.  相似文献

While research demonstrates the importance of numeracy-related activities performed at home for young children's mathematics achievement, few studies involve observational studies of the processes which support children's mathematical learning at home. On this premise, this study reports evidence from numeracy-related interactions between parents and their four-year-old child during cookery sessions at home. Numeracy group parents who received instructions to incorporate additional mathematics into the activity provided significantly more numeracy guidance and also created more opportunities for their children to practice advanced mathematics. Comparison group parents provided enough numeracy guidance to complete the recipe but rarely provided extensive or advanced numeracy guidance. Children in the numeracy group generated significantly more correct math responses during the activity than comparison group children, though there were no significant differences on the post-test. The findings suggest the need to raise parental awareness of opportunities to support and encourage mathematics in activities at home.  相似文献
