Implementing technical refinement in high-level athletics: exploring the knowledge schemas of coaches

This paper explores the approaches adopted by high-level field athletics coaches when attempting to refine an athlete’s already well-established technique (long and triple jump and javelin throwing). Six coaches, who had all coached multiple athletes to multiple major championships, took part in semi-structured interviews focused upon a recent example of technique refinement. Data were analysed using a thematic content analysis. The coaching tools reported were generally consistent with those advised by the existing literature, focusing on attaining “buy-in”, utilising part-practice, restoring movement automaticity and securing performance under pressure. Five of the six coaches reported using a systematic sequence of stages to implement the refinement, although the number and content of these stages varied between them. Notably, however, there were no formal sources of knowledge (e.g., coach education or training) provided to inform coaches’ decision making. Instead, coaches’ decisions were largely based on experience both within and outside the sporting domain. Data offer a useful stimulus for reflection amongst sport practitioners confronted by the problem of technique refinement. Certainly the limited awareness of existing guidelines on technique refinement expressed by the coaches emphasises a need for further collaborative work by researchers and coach educators to disseminate best practice.     

SHAPE America’s 50 Million StrongTM: Critical Research Questions Related to Youth Physical Activity

SHAPE America – Society of Health and Physical Educators has targeted youth physical activity (PA) as 1 of its 4 goals within the 50 Million Strong^TM campaign. Only 27.1% of youth met the target of all students (preK–12) participating in at least 60 min of PA that increases their heart rate enough to breathe hard at least some of the time for 7 days/week. Thus, improvements for child and adolescent engagement in PA need to be made now through 2029 and beyond. The need for these improvements warrants research related to PA and youth. We present a plethora of research questions within 3 general areas: PA and school PA programs, PA and sedentary behavior measurement, and PA and social justice imperatives. Each question is framed within the social-ecological framework levels of learning, opportunity, policy, and population health.     

Mechanics as the Logical Point of Entry for the Enculturation into Scientific Thinking

Force in modern classical mechanics is unique, both in terms of its logical character and the conceptual difficulties it causes. Force is well defined by a set of axioms that not only structures mechanics but science in general. Force is also the dominant theme in the ‘misconceptions’ literature and many philosophers and physicists alike have expressed puzzlement as to its nature. The central point of this article is that if we taught mechanics as the forum to discuss the nature of mechanics itself, then we would serve to better secure a learner’s understanding and appreciation of both science and mathematics. We will attempt to show that mechanics can provide the opportunity for students to enter this meta-discourse by engaging in Socratic discussion, entertaining thought experiments, comparisons made between force as defined within mechanics as a modern axiomatic system with Newton’s quantitative definition of force, how the concepts of force prior to Galileo and Newton can be used as a teaching aid with respect to student intuitive ideas and how mathematics was brought to bear on what is given empirically. Mechanics provides this opportunity and pedagogically may require it due to its axiomatic nature.

Para-adventure: a hyper-dynamic problem for the inclusive coach

Recent research has recognized sports coaching as complex, chaotic and cognitively taxing for coaches. Against this backdrop, the present paper explores challenges faced by high-level coaches working with disabled performers. Specifically, it seeks to understand how coaches create mental models of performance in adventure sports and para-canoe. Five coaches were purposively sampled and underwent a semi-structured interview. A thematic analysis revealed conceptualizing the mental model as being mechanically related for all and as including a social construction within the para-canoe coaches. Reflection on the coaching process and on personal characteristics were perceived as important to individualized inclusive coaching. Coach training should particularly emphasize the need for critical judgement and decision-making skills within a similarly oriented social structure of coaches and support staff where applicable.     

Youth leaders' perceptions of commitment to a responsibility-based physical activity program

This study extended Schilling's (2001) study by investigating program commitment among a larger (N = 12), older (M = 16.7 years), and more experienced (M = 5.96 years) sample of participants in the Project Effort Youth Leader Corps. Individual interviews elicited a greater number and specificity of themes. Program-related barriers included logistics, structure, and relationships, and personal-related barriers included perceived alternatives, personal characteristics, and "real-life" responsibilities. Similar to Schilling's (2001) earlier study, antecedents grouped under program environment, program structure, relationships, and personal characteristics. Participants also described outcomes in terms of behavior and emotional involvement but reported more themes related to leadership. Results are discussed in terms of consistencies and changes over time and implications for program development, expansion, and evaluation.
