ABSTRACT

The aims of this study are (a) to describe the evolution of neuromuscular performance over an 18 year period within a Spanish elite reserve team; (b) to check if there were any relation between the playing position and sprint and jump performances and (c) to look into the alleged impact of this factor on the top playing level attained by the soccer players. We considered the physical tests (5 m and 15 m sprint times and countermovement jump (CMJ) height) made by 235 players enrolled in the reserve team of the Club from 1994 to 2012 and the highest competitive-level they achieved: Spanish first (n = 39) and second divisions (n = 36) and semi-professional (n = 160). Furthermore, the players were classified according to their playing positions. The main findings were a very-likely/most-likely lower neuromuscular performance (ES = 0.48–0.68, small to moderate) in the last six-season term (2006–2012) than in the first term (1994–2000); possibly/very-likely lower performances in sprinting and CMJ (ES = 0.22–0.55, small) by central defenders (CDs) and midfielders than by other playing positions; very-likely better performances in sprinting and jumping by first and second divisions central defenders than by semi-professional central defenders (ES = 0.90–1.02, moderate). Sprint and jump performances are not a relevant physical parameter to promote to the top level of soccer in Spain except for one in six of the playing positions: CDs.  相似文献

We investigated Dutch word stress acquisition in 3‐year‐old children at risk of dyslexia (children with at least one parent or older sibling with reading difficulties) and normally developing children, in order to shed light on language acquisition delays in children at risk of dyslexia, as well as to investigate further phonological deficits in dyslexia. The children had to repeat non‐words with stress patterns varying in regularity. Both the at‐risk and control children performed better on imitation of regular stress targets and worse on irregular and prohibited stress patterns. However, the at‐risk children showed more difficulty imitating irregular and prohibited patterns, and had lower percentages phonemes correct than the control group. The results can be interpreted as a delay in word stress acquisition in the at‐risk group. The findings thus point towards a phonological deficit early in language development.  相似文献

Abstract High physical fitness in childhood and adolescence is positively associated with favourable health-related outcomes. Our aim was to examine the relationship between relatives' (father, mother, brother, sister, and best friend) physical activity engagement and encouragement on adolescents' physical fitness. Adolescents were part of the HELENA study, a multi-centre study conducted in 10 cities from nine European countries in 2006-2008. Participants were 3288 adolescents (48% boys, 52% girls) aged 12.5-17.5 years with valid data on at least one of the three fitness variables studied: muscular strength (standing long jump), speed/agility (4×10 m shuttle run), and cardiorespiratory fitness (20 m shuttle run). The adolescents reported their relatives' physical activity engagement and encouragement. Analysis of covariance showed that relatives' physical activity engagement (father, mother, brother, and best friend) was positively related to cardiorespiratory fitness (P?相似文献

Abstract

The purpose of our study was to carry out a writing workshop in a collaborative setting in which the teacher and the 14 year-old students made up stories while being observed by a researcher. We used a qualitative methodology similar to the Ethnography of Communication and Discourse Analysis, in which narrative and analytical analyses are seen as complementary, in order to interpret all aspects of the participants’ activities. The analysis of the conversations held in the different working situations defined by the presence or absence of the teacher shows that the guiding role played by the teacher is essential in terms of the students’ acquisition of knowledge concerning the generalization of meanings, the organization of social relations and the structuring of the task. Likewise, within a group of peers involved in working towards a common goal, one or several of them tend to take on the guiding role when the teacher is not present.  相似文献

ABSTRACT

Professional development is a critical systems-level intervention thought to facilitate Response-to-Intervention (RtI) implementation. The current study examined the relations between professional development, educator outcomes, and problem-solving implementation within an RtI framework using growth curve modeling. School leadership teams from pilot schools (= 34) participated in 3 years of training. Pilot schools also received job-embedded coaching. Comparison schools (= 27) provided a referent group. Results indicated that problem-solving implementation increased faster at pilot schools (β = 0.10, SE = 0.05, t = 2.03, p < .05). In addition, beliefs regarding data-based decision-making (β = 0.36, SE = 0.17, t = 2.13, p < .05) and perceived problem-solving skills applied to academics (β = 0.30, SE = 0.10, t = 3.07, < .01) positively related to implementation. Implications include the needs to further explore professional development activities and for consultants to utilize evidence-based professional development principles when supporting RtI implementation.  相似文献

This study documents the extent of sexual content, including sexual health content, in scenes with and without expressions of love on network and cable television popular with emerging adults. Sexual talk and/or behavior was found in 20% of all television scenes coded across 53.5 hours of programming. One third of these scenes featured sex alongside expressions of love. An additional 10% of scenes suggested love but not sex. Coded as a separate category, 25% of analyzed scenes contained a passing joke or pun referencing sexual organs, making these nonspecific, comedic one-liners the predominant reference to sex in this sample. Beyond jokes, most of the sexual or loving talk in this sample consisted of expressing a romantic interest in someone; sex- and love-related behaviors largely consisted of kissing or flirting. Very few scenes specifically referenced sexual intercourse. Sexual health messages were also rare. The majority of scenes mentioning any health consequence (7% of analyzed scenes) concerned emotional heartache. One scene mentioned sexually transmitted infections; 12 of the nearly 2,600 scenes coded mentioned condoms or contraceptives. It is thus a challenging proposition to build upon existing sexual depictions on television to promote safe sex practices within sexual and loving contexts.  相似文献

Recent studies indicate that the majority of school psychologists’ time continues to be dedicated to SPED related activities. Despite ongoing calls for school psychologists to expand their roles, why many practitioners do not deliver more comprehensive services is not well understood. This qualitative study investigated facilitators of and barriers to comprehensive and integrated services using the National Association of School Psychologists Model for Comprehensive and Integrated School Psychological Services as the guiding framework. Thirteen full‐time, school‐based practitioners from across the US participated in semi‐structured interviews. Constant‐comparative analysis was used to generate themes. Results indicated that practitioners experienced a number of systemic barriers to (e.g., heavy caseload; inconsistent district policies, priorities, and role definitions; lack of stakeholder involvement) and facilitators of (e.g., resources, graduate training and professional development) comprehensive and integrated service delivery. Participants’ perspectives regarding changes needed to expand their services focused on systemic issues as well. Implications for research and practitioners’ efforts to advocate for systems change are discussed.  相似文献
