Psychological Skills and Characteristics Facilitative of Youth Athletes’ Development: A Systematic Review

Lea-Cathrin Dohme, David Piggott, Susan Backhouse, and Gareth Morgan

review is to provide such synthesis by fulfilling three objectives: to identify PSCs perceived as facilitative of talented youth athletes’ development, to group and label synonymous PSCs, and to categorize PSCs based on definitions established by Dohme et al. ( 2017 ). Method Development of Search

Reflecting on the Development of a Conceptual Framework for Sport Coaching

John Lyle

process has been a continuing feature of my work since that time. The initial ‘contents list’ for the coaching theory module reflected a number of themes: role, definitions, philosophy (approach), responsibilities, and sport-specific behaviours. These were rehearsed in an early publication ( Lyle, 1981

What Is Physical Literacy? An International Review and Analysis of Definitions

Despite its popularity, questions remain about the coherence of the definitions used within the physical literacy field ( Bailey, 2021 ; Keegan

Competence—One Term, Various Definitions: A Scoping Review for Sports Coach Education and Research

-speaking countries (especially acquisition of competence) ( Grote et al., 2006 ; Hapke & Engelhardt, 2022 ). Such complications appear to preclude an overarching definition of competence ( Baumgartner, 2022 ; Blömeke et al., 2015 ; Soderquist et al., 2010 ; Tul et al., 2019 ). This complicates the discourse on

These models often use different trunk segment boundaries 12 , 15 and may exclude regions of the hips based on trunk and thigh segment definitions. 16 These regions may be significant in obese adults. This is of particular concern in light of previous work demonstrating that age and

Overuse Injury Definitions and Rates of Overuse Injury in Epidemiology Studies Concerning High School-Aged Athletes: A Critically Appraised Topic

Furthermore, for the studies that did have a definition, some defined

Physical Activity Self-Definitions: Correlates and Perceived Criteria

Deborah Kendzierski, R. Michael Furr Jr., and Jennifer Schiavoni

Three studies investigated the correlates of physical activity self-definitions among undergraduate exercisers and athletes, and examined the perceived criteria for defining oneself as a weightlifter, basketball player, and exerciser. Perceptions about behavior, motivation-related variables, and social world variables showed consistent relationships with self-definition; correlations between self-definition and enjoyment varied according to activity. Although affective criteria were mentioned by a sizable number of those with and without physical activity self-definitions, participants cited far more behavioral than affective criteria. Other frequently mentioned criteria were also identified. Implications for self-inference are discussed and a preliminary model of physical activity self-definition is presented.

Operational Definitions of Walkable Neighborhood: Theoretical and Empirical Insights

Anne Vernez Moudon, Chanam Lee, Allen D. Cheadle, Cheza Garvin, Donna Johnson, Thomas L. Schmid, Robert D. Weathers, and Lin Lin


The concept of walkable neighborhoods is increasingly important in physical activity research and intervention. However, limited theoretical understanding and measurable definitions remain a challenge.


This paper reviews theories defining neighborhoods and offers an empirical approach to identify measurable attributes and thresholds of walkable neighborhoods. Bivariate and multivariate analyses are used for self-reported socio-demographic background, neighborhood walking behavior and perception, and objective measures of environments.


Environmental attributes positively associated with walking sufficiently to meet health recommendations included higher residential density and smaller street-blocks around home, and shorter distances to food and daily retail facilities from home. Threshold distances for eating/drinking establishments and grocery stores were 860 and 1445 feet.


Results questioned theoretical constructs of neighborhoods centered on recreation and educational uses. They pointed to finer mixes of uses than those characterizing suburban neighborhoods, and small spatial units of analysis and intervention to capture and promote neighborhood walkability.
