Key somatic variables associated with,and differences between the 4 swimming strokes

ABSTRACT

This study identified key somatic and demographic characteristics that benefit all swimmers and, at the same time, identified further characteristics that benefit only specific swimming strokes. Three hundred sixty-three competitive-level swimmers (male [n = 202]; female [n = 161]) participated in the study. We adopted a multiplicative, allometric regression model to identify the key characteristics associated with 100 m swimming speeds (controlling for age). The model was refined using backward elimination. Characteristics that benefited some but not all strokes were identified by introducing stroke-by-predictor variable interactions. The regression analysis revealed 7 “common” characteristics that benefited all swimmers suggesting that all swimmers benefit from having less body fat, broad shoulders and hips, a greater arm span (but shorter lower arms) and greater forearm girths with smaller relaxed arm girths. The 4 stroke-specific characteristics reveal that backstroke swimmers benefit from longer backs, a finding that can be likened to boats with longer hulls also travel faster through the water. Other stroke-by-predictor variable interactions (taken together) identified that butterfly swimmers are characterized by greater muscularity in the lower legs. These results highlight the importance of considering somatic and demographic characteristics of young swimmers for talent identification purposes (i.e., to ensure that swimmers realize their most appropriate strokes).     

Specific Learning Difficulties (Dyslexia): Equal Opportunities Issues

Their article raises important questions concerning the lack of attention to issues of equal opportunity in the literature on specific learning difficulties. The authors identify five objectives for professional practice and research.     

The Right to Teach, the Right to Learn

Believe that the findings and recommendations of the Elton Committee have much to offer schools for children with emotional and behavioural difficulties, as well as mainstream schools. They outline the way they have introduced 'assertive discipline' into behaviour management policy of the school.     

Academic Development as Academic Work

In this paper the authors reflect on their experiences of being academic developers and suggest how our profession might advance in the future. Our inquiry focuses on academic development and how we can support our clients more effectively. We propose that the profession of academic development should aim for academic status with many more research‐active staff contributing to its knowledge base. If this profession were located within the already recognized research field of higher education, we believe a number of potential benefits could accrue. These include a new level of professional standing, greater efficiency in our universities and a more substantial academic development community. Our thoughts and arguments on the nature of our work are framed within a discussion of professional identity, knowledge and academic freedom.     

Behaviour,race and inclusion

Abstract

This article argues that because of the practice in the 1960s of placing black children in so-called ‘educational subnormal’ units there is now a reluctance to look at the speci?c needs of African Caribbean children. The post-Warnock politics of integration/inclusion following this period point to the ‘institutional racism’ of schools and white teachers to explain poor exam results. This article argues that in the current political climate which prioritizes ‘inclusion’ we should not patronize the black child. There is a need to position the factors of oppression equally with other factors of underachievement; to re-employ psychological, behavioural and educational tools as well as to deconstruct school processes and teacher attitudes; and to consider psychosocial factors related to underachievement without forgetting the reality of institutional racism. The article illustrates a research project that looks at the pastoral needs of African Caribbean children. It points to these needs as the key variable in unlocking their underachievement at school.
