Abstract In this study, we investigated changes in creatine kinase, perceptual and neuromuscular fatigue of professional rugby league players after match-play. Twenty-three male rugby league players (10 backs, 13 forwards) had their creatine kinase, perceptual ratings of fatigue, attitude to training, muscle soreness, and flight time in a countermovement jump measured before and 1 and 2 days after (day 1 and day 2 respectively) league matches. Total playing time, offensive and defensive contacts were also recorded for each player. Creatine kinase was higher both 1 and 2 days after than before matches (P < 0.05) in forwards and backs. Similarly, perceived fatigue and muscle soreness were higher than pre-match on both days 1 and 2 (P < 0.05), but did not differ between groups (P > 0.05). Jump performance was lower on day 1 but not day 2 for both groups (P < 0.05). While total playing time was longer in backs (P < 0.05), relative frequencies for all contacts were greater in forwards (P < 0.05). Contacts for forwards were correlated with all markers of fatigue (P < 0.05), but only flight time was correlated with offensive contacts in backs (P < 0.05). Despite the mechanisms of fatigue being different between forwards and backs, our results highlight the multidimensional nature of fatigue after a rugby league match and that these markers do not differ between positions. 相似文献

ABSTRACTThe study assesses the test–retest reliability of movement and physiological measures during a simulated rugby match that employed activities performed in a stochastic order. Twenty male rugby players (21.4 ± 2.1 y) completed two trials of a 2 × 23 min rugby movement simulation protocol during which the order of events was performed in a stochastic order, with 7–10 days between trials. Movement characteristics, heart rate (HR), RPE, maximum voluntary contraction (MVC), voluntary activation (VA%) of the quadriceps, Stroop test and subjective task load rating (NASA-TLX) were measured. The most reliable measures of external load was relative distance (typical error [TE] and CV% = 1.5–1.6 m min?1 and 1.4–1.5%, respectively), with all other movement characteristics possessing a CV% <5%. The most reliable measure of internal load, neuromuscular function and perceptual measures were for %HRmax (TE and CV% = 1.4–1.7% and 1.4–2.1%, respectively), MVC before (TE and CV% = 10.8–14.8 N·m and 3.8–4.6%, respectively), and average RPE (TE and CV% = 0.5–0.8 AU and 3.6–5.5%, respectively). The Stroop test, NASA-TLX and blood lactate produced the least reliable measures (CV% >5%). Future studies can confidently examine changes in several perceptual, neuromuscular, physiological and movement measures related to rugby activity using stochastic movements. 相似文献

The tutor‐web is an open‐source learning environment designed to be used for teaching mathematics and statistics. The system offers thousands of exercises at high school and university level, and has been used for a decade to teach introductory statistics courses with good results. A new component has recently been added to the tutor‐web so that students can enter their own data or get real data from several data sources for practicing and learning new concepts. 相似文献

Changing Teacher–Child Dyadic Interactions to Improve Preschool Children's Externalizing Behaviors 下载免费PDF全文

A randomized controlled trial was used to examine the impact of an attachment‐based, teacher–child, dyadic intervention (Banking Time) to improve children's externalizing behavior. Participants included 183 teachers and 470 preschool children (3–4 years of age). Classrooms were randomly assigned to Banking Time, child time, or business as usual (BAU). Sparse evidence was found for main effects on child behavior. Teachers in Banking Time demonstrated lower negativity and fewer positive interactions with children compared to BAU teachers at post assessment. The impacts of Banking Time and child time on reductions of parent‐ and teacher‐reported externalizing behavior were greater when teachers evidenced higher‐quality, classroom‐level, teacher–child interactions at baseline. An opposite moderating effect was found for children's positive engagement with teachers. 相似文献

Burden of Acting Neither White Nor Black: Asian American Identities and Achievement in Urban Schools
Jamie Lew 《The Urban Review》2006,38(5):335-352
Ogbu’s theory of “burden of acting white” has been one of the most frequently cited studies to explain black and white achievement
gap. However, emerging studies have argued that Ogbu’s theory may be limited when examining variability of school achievement
among black and white students. Research shows that in addition to culture, other social forces, such as class, peer networks,
and school context may play a significant role when accounting for minority students’ academic aspirations and achievement.
In the midst of this on-going debate, however, there is a limited understanding of how, if at all, theory of “acting white”
plays a role for racial groups other than black and white students. By extending the discussion beyond a black-and-white discourse,
this research examines how Asian American students in two different social and economic contexts, negotiate their race and
ethnic identities. Framed by a prevalent model minority stereotype that conflates Asian Americans with whiteness, the findings
show that portrayal of Asian “success” much like black “failure” cannot be explained solely on their cultural orientation.
By comparing experiences of two groups of Korean American students—both high- and low-achieving—in different economic and
school contexts, this study illustrates how the two groups of Korean American students adopt different racial strategies depending
on their socioeconomic backgrounds, peer networks, and school contexts. Using Korean American students in urban schools as
a case study, this research complicates and challenges our understanding of the role of culture in school achievement and
illustrates how culture intersects with class, race, and schools.

Teacher attitudes toward inclusion of English Learners (ELs) in the mainstream classroom have primarily focused on explicit beliefs as accessed through observation, case studies, and self-report surveys. The authors explore implicit mainstream teacher beliefs about ELs using the newly created Implicit Association Test–EL, with correlations to explicit beliefs being made using the English-as-a-Second-Language (ESL) Students in Mainstream Classrooms: A Survey of Teachers’ Explicit Beliefs survey. Findings from the IAT–EL indicate a slightly negative implicit belief about ELs from 197 respondents. Implicit and explicit beliefs about ELs were not significantly correlated, which is in keeping with current Implicit Associate Test (IAT) literature. 相似文献

When do adolescents' dreams of promising journeys through high school translate into academic success? This monograph reports the results of a collaborative effort among sociologists and psychologists to systematically examine the role of schools and classrooms in disrupting or facilitating the link between adolescents' expectations for success in math and their subsequent progress in the early high school math curriculum. Our primary focus was on gendered patterns of socioeconomic inequality in math and how they are tethered to the school's peer culture and to students' perceptions of gender stereotyping in the classroom. To do this, this monograph advances Mindset × Context Theory. This orients research on educational equity to the reciprocal influence between students' psychological motivations and their school-based opportunities to enact those motivations. Mindset × Context Theory predicts that a student's mindset will be more strongly linked to developmental outcomes among groups of students who are at risk for poor outcomes, but only in a school or classroom context where there is sufficient need and support for the mindset. Our application of this theory centers on expectations for success in high school math as a foundational belief for students' math progress early in high school. We examine how this mindset varies across interpersonal and cultural dynamics in schools and classrooms. Following this perspective, we ask:
- 1. Which gender and socioeconomic identity groups showed the weakest or strongest links between expectations for success in math and progress through the math curriculum?
- 2. How did the school's peer culture shape the links between student expectations for success in math and math progress across gender and socioeconomic identity groups?
- 3. How did perceptions of classroom gender stereotyping shape the links between student expectations for success in math and math progress across gender and socioeconomic identity groups?

Children's ethnicity-status associations are often studied in societies where one ethnic group possesses status across multiple dimensions, such as political influence and wealth. This study examined children's (6–12 years) and adults' representations of more complex hierarchies in Indonesia (N = 341; 38% Native Indonesian, 33% Chinese Indonesian, and 27% other ethnicities; 55% female, 36% male; 2021–2022), a society where ethnic groups hold distinct forms of status (on average, Native Indonesians have political influence; Chinese Indonesians have wealth). By 6.5 years, children associated Native Indonesians with political influence and Chinese Indonesians with wealth. Intersectional analyses indicated that ethnicity-status associations were stronger for male than female targets. Children of all ethnicities preferred Chinese Indonesians and preferences were predicted by wealth judgments. 相似文献
