Dynamic balance performance varies by position but not by age group in elite Rugby Union players – a normative study

This cohort study aimed to provide normative Y Balance Test scores for an elite Rugby Union population, while investigating the effect player age groups (senior/under-20), playing positions (forwards/backs) and anthropometrics (height and body mass) had on performance. Two-hundred and sixty-one elite male under-20 (n = 50) and senior (n = 211) players completed baseline Y Balance Test during the 2015/2016 season. One-way ANCOVA and post-hoc t-tests were used to investigate the effect playing position, player group, height and weight had on performance. The cohort was then stratified into groups (age group and/or playing position), and normative percentiles were presented. There was a statistically significant difference (p < 0.05) in Y Balance Test performance between playing positions, when controlling for age group. This difference did not remain when controlling for player body mass. Post-hoc analysis demonstrated that backs had a longer normalised reach distance, with medium-large and small-medium effect sizes for the under-20 and senior cohorts respectively. The one-way ANCOVA analysis suggests that this difference is likely due to the larger differences in player body mass between forward and back playing positions. The normative values presented in this paper may be used by clinicians and researchers to aid injury prevention and rehabilitation strategies.     

The role of early childhood settings for 4–5 year old children in early academic skills and later achievement in Australia

Formal early childhood education programs have been shown to promote the early academic skills of young children. However, the academic benefits acquired through program attendance fade quickly in the early elementary school years. Using a nationally representative sample of Australian children, we describe the programmatic and teacher differences between different types of formal early childhood programs for children between 4 and 5 years old—pre-year 1, school-based preschool, standalone preschool, and center-based child care. We examine the child and family background characteristics that are correlated with selection into different settings and how these settings are associated with children's early academic skills and on their subsequent achievement. We focus on understanding if there are differential academic benefits accrued from each program type and whether or not these benefits persist into the early elementary school years. Results indicate that maternal employment and economic disadvantage are correlated with program participation and that pre-year 1 and preschool teachers have higher qualifications. Results also show that children who attended a pre-year 1 program held an initial, significant advantage in early academic skills compared to children enrolled in center child care. Center child care was associated with higher early math skills than preschools. Children who did not attend any early childhood programming lagged behind their peers in school readiness skills. By middle childhood, all the early skill advantages had disappeared, showing rapid fadeout of academic benefits acquired from these specific types of early childhood programs. Implications for policy and practice are discussed.     

Sources of Job Satisfaction in Science Secondary School Teachers in Chile

The paper aims to augment the limited literature on teacher job satisfaction in developing countries, specifically in Chile. The nature of job satisfaction in Chilean secondary science teachers is investigated and causes of satisfaction and dissatisfaction identified. Teachers mentioned most often their satisfaction with interactions with students, relationships held within the school and opportunities to contribute to the development of society, future generations or the individual. Sources of dissatisfaction are poor salary, excessive workload, student characteristics, resources and infrastructure. Associations between teachers' characteristics (age, gender, experience), the type of school administration and job satisfaction are also made and suggestions on how to address the issues of teacher satisfaction and dissatisfaction are discussed.     

‘Society has taught us to judge’: cultures of the body in teacher education

The body is a powerful symbolic form and all bodily activities are expressions of culture. The look, size, shape and physicality of bodies are perceived by all and compared to particular cultural standards. In this way the body is inscribed with culture and can serve as a site for social control. Various discourses of the body, including those around appearance, health and fitness, circulate within societal institutions and through relations of power these impact on the way in which we come to understand bodies. In times marked by individualised responsibility for all aspects of life, the body and technologies of self around bodywork are also significant in relation to self-formation and self-government. This research investigates the impact of various cultures of the body, on pre-service physical education teachers' understandings and meaning making about bodies, fitness, health and personal engagement in bodywork. Implications for future practices in teaching, relationships with school students and messages for teacher educators are also considered.

Negotiating a critical agenda in middle years physical education

In this research a number of strategies including physical experiences, physical stories and lab school with guided reflection were used with pre-service physical education teachers in an attempt to foster more critical and inclusive approaches to teaching physical education in the middle years. The strategies were used to illustrate the complex processes that inhibit or enhance an individual’s relationship to physical activity. They served to identify discursive, social and institutional practices, which supported the development of a physical identity for some young people while powerfully denying it to others. Pre-service physical education teachers were asked to respond to these strategies in multiple ways as well as constructing their own knowledge around teaching and learning in physical education. It was concluded that a more complete understanding of young people’s physicality could develop from recognition of the complex interrelationships that occur between school, culture and physical experiences. The strategies used allowed insights into these complexities and worked to develop a deeper appreciation of ‘lived’ experiences, around physical education. Opportunities to explore and critically reflect on teaching and student learning were also found to be significant in considering broadened understandings of pedagogies of physical education.     

Adductor longus mechanics during the maximal effort soccer kick

Groin pain is a common cause of athletic disability and often involves the adductor longus. A common complaint of patients with groin problems is pain while preparing to kick the ball. The purpose of this study was to examine muscle length and activation of the adductor longus while kicking a soccer ball. Three-dimensional joint positions and muscle activation were obtained from 15 National Collegiate Athletic Association (NCAA) Division 1 male soccer players during maximal effort kicks. Musculoskeletal modeling techniques incorporating joint position and muscle attachments were used to estimate adductor longus length from the beginning of the kicking leg's swing phase until ball strike. The maximum rate of stretch of the adductor longus (22.3 ± 5.3 cm/s) and maximum hip extension (23.3 ± 8.8°) occurred near 40% of swing phase. Activation of the adductor longus occurred between 10% and 50% of the swing phase. Adductor longus maximum length occurred at 65% of the swing phase. Maximum hip abduction (25.3 ± 5.4°) occurred at 80% of swing phase. The adductor longus appears to be at risk of strain injury during its transition from hip extension to hip flexion. This knowledge could be applied to muscle injury prevention and rehabilitation programs to aid with treatment of adductor longus related groin pain.
