Effects of a short-term pre-season training programme on the body composition and anaerobic performance of professional rugby union players

Abstract

Pre-season rugby training develops the physical requisites for competition and consists of a high volume of resistance training and anaerobic and aerobic conditioning. However, the effects of a rugby union pre-season in professional athletes are currently unknown. Therefore, the purpose of this investigation was to determine the effects of a 4-week pre-season on 33 professional rugby union players. Bench press and box squat increased moderately (13.6 kg, 90% confidence limits ±2.9 kg and 17.6 ± 8.0 kg, respectively) over the training phase. Small decreases in bench throw (70.6 ± 53.5 W), jump squat (280.1 ± 232.4 W), and fat mass (1.4 ± 0.4 kg) were observed. In addition, small increases were seen in fat-free mass (2.0 ± 0.6 kg) and flexed upper-arm girth (0.6 ± 0.2 cm), while moderate increases were observed in mid-thigh girth (1.9 ± 0.5 cm) and perception of fatigue (0.6 ± 0.4 units). Increases in strength and body composition were observed in elite rugby union players after 4 weeks of intensive pre-season training, but this may have been the result of a return to fitness levels prior to the off-season. Decreases in power may reflect high training volumes and increases in perceived of fatigue.     

State Anxiety as a Function of Skill Level and Proximity to Competition

Abstract

The purpose of this study was to investigate differences between the oversized racquet and the standard-sized racquet in (1) a tennis shot accuracy test on four basic strokes (ground strokes, volley, return of serve, and serve), and (2) a measure of players' subjective evaluation of playability (control, accuracy, power, and feel). Research participants (n = 57) were undergraduate students separated into two skill levels, intermediate (n = 29) and beginners (n = 28). Data were analyzed using a two-factor ANOVA with repeated measures on one factor. Result from the skills tests indicated that both beginning and intermediate groups scores significantly higher when using the oversized racquet. The scores received when using the oversized racquet tended to reflect a general increase in all four components of the skill test, particularly the return of serve. Data indicated that the subjective evaluation of the playing characteristic of each racquet was influenced by the player's skill level. Beginning players favored the oversized racquet, yet intermediate players rated the two racquet types about equal. The investigation suggests that beginning and intermediate tennis players, educators, and tennis teaching professionals should consider using and encouraging the use of oversized racquets.     

Development of the Sport Orientation Questionnaire

Abstract

The Sport Orientation Questionnaire (SOQ) was developed as a multidimensional, sport-specific measure of individual differences in sport achievement orientation. Exploratory and confirmatory factor analyses revealed a stable, three-factor structure across three separate samples of university and high school students. The three separate but related subscales of competitiveness, win, and goal orientation demonstrate high internal consistency and stability over time. The SOQ competitiveness score differentiates students in competitive activities from those in noncompetitive activities, providing evidence for construct validity. The overall factor stability, reliability and validity evidence suggests that the SOQ can be a valuable measure for the investigation of competitiveness and achievement behavior in sport and exercise settings.     

Estimated maturity status and perceptions of adult autonomy support in youth soccer players

Abstract

In this study, we examined the relations between biological maturity status, body mass index, age, and perceptions of adult autonomy support in the context of youth soccer. A total of 70 female and 43 male soccer players, aged 9 – 15 years, completed three adult-specific versions (i.e. mother, father, coach) of the perceived autonomy support subscale from the Interpersonal Style Scale. The participants' percent predicted adult stature was used as an estimate of biological maturity status. Multiple linear regression analyses revealed that advanced maturity status in male players predicted lower perceptions of autonomy support from the coach. Maturity status was unrelated to perceptions of autonomy support from the coach in female soccer players, and paternal and maternal autonomy support in male and female players. Age and body mass index were unrelated to perceptions of adult (i.e. coach, mother, father) autonomy support in male and female players.     

Competition and Instructional Set Effects On the Speed and Accuracy of a Throwing Task

Abstract

Two experiments were conducted to investigate the effects of competition and instructional sets on the speed and accuracy of a dart-throwing task. In both experiments individuals competed against another subject on one day, and performed under noncompetitive conditions on a second day. The five distinct instructional sets varied from extreme emphasis on speed to extreme emphasis on accuracy. Multivariate analyses of variance revealed main effects for instructional sets on speed and accuracy in both experiments. Strong tradeoffs occurred with speed slowing and accuracy improving as the instructional emphasis changed from speed to accuracy. A competition by instructional sets interaction in Experiment 2 indicated that competition facilitated speed when speed was important, but when instructions emphasized accuracy, speed was slower in competition than in noncompetition. Accuracy was not affected by competition.     

Wikipedia,Critical Social Theory,and the Possibility of Rational Discourse 1

Information systems researchers that apply critical social perspectives frequently emphasize the potential for information technology to serve as a mechanism for increased rationalization, domination, and control. Such theorists often overlook or discount the liberating aspects of information systems. In this study, we apply the ideal of rational discourse developed by Jürgen Habermas to the phenomenon of Wikipedia in an effort to explore empirically the emancipatory potential of information systems. We contend that Wikipedia embodies an approximation of the necessary conditions for rational discourse. While several challenges persist, the example of Wikipedia illustrates the positive potential of information systems in supporting the emergence of more emancipatory forms of communication. The corresponding implications for researchers and design professionals alike are discussed.     

An ethic of care and educational practice

This article explicates the theoretical framework of an ethic of care and outlines recommendations for applying the framework to practice in adventure education, offering possibilities for re-imagining organizations as centrally concerned with compassion and care. Focusing on the work of Gilligan and Noddings, we suggest an understanding of an ethic of care that is contextual, ungendered, and inclusive of both the private and public spheres of life, and draw parallels between this ethic and the philosophies underlying Outward Bound specifically, and adventure education more generally. Finally, we outline possibilities for organizing educational curricula around centres of care for self, others, and the natural world, using Noddings' suggested curricular components of modeling, dialogue, practice, and confirmation.     

The act of collective worship: pupils’ perspectives

Data gathered as part of a recent research project into the provision of collective worship in schools in England and Wales reveals the existence of a marked variation in approach and provision between schools in the primary and secondary sectors. Consequently, the point of transfer often becomes a watershed in pupils’ experience. This sudden change, which is most apparent in community schools, is accompanied by a slower but pre-existing transition in attitudes which is common to pupils in all types of institution. Using material gathered from interviews with young people, this article examines the issue of participation in school worship from the pupils’ perspective and analyses the reasons they give for their opposition to provision. It then compares these attitudes with those of a previous generation, as demonstrated in the work of Loukes (1961 Loukes H (1961) Teenage Religion (London, SCM)  [Google Scholar]) and Goldman (1964 Goldman R (1964) Religious Thinking from Childhood to Adolescence (London, Routledge & Kegan Paul)  [Google Scholar], 1965 Goldman R (1965) Readiness for Religion (London, Routledge & Kegan Paul)  [Google Scholar]) in order to explore the underlying changes which influence students’ thinking. It concludes with a consideration of the implications of these findings for practice and policy.     

Barriers to professional education of NSW correctional officers: A case of distance learning

This study aimed to determine whether NSW prison officers who attempt tertiary education are confronted with any unique cultural and contextual impediments during their studies and, if so, the effects of these impediments. Semi‐structured interviews were carried out, face‐to‐facc with 16 prison officers. The study also contrasts the experiences of commissioned and non‐commissioned correctional officers.

Three major thematic strands emerged from the data. The first clear theme involves the general barriers to learning encountered by prison officers engaged in tertiary studies. These barriers include time constraints and time management, family commitments and access to support mechanisms. The second major theme concerns the influence on the education process of the powerful occupational culture that has developed in the prison workplace. The third theme highlights the difficulties the occupation of prison officer presents for those individuals pursuing tertiary studies in the distance education mode. Geographically isolated work locations, a changing shift roster and high levels of job‐related stress all conspire against the success of prison officers as ‘distance learners’.     

Assessment of semi-empirical mass transfer correlations for pervaporation treatment of wastewater contaminated with chlorinated hydrocarbons

INTRODUCTION Chlorinated hydrocarbons, a class of widely used dry-cleaning liquids, industrial organic solvents, and degreasers, increasingly find their way into drinking water sources, thus posing a very serious health and environmental problem (Love and Eliers, 1982). These organic solvents are known for their stability in the environment and cancer-causing po- tency and cannot be effectively and economically eliminated by current conventional treatment tech- nologies. One of the few av…
