Mediating effects of resistance training skill competency on health-related fitness and physical activity: the ATLAS cluster randomised controlled trial

The purpose of this study was to examine the mediating effect of resistance training skill competency on percentage of body fat, muscular fitness and physical activity among a sample of adolescent boys participating in a school-based obesity prevention intervention. Participants were 361 adolescent boys taking part in the Active Teen Leaders Avoiding Screen-time (ATLAS) cluster randomised controlled trial: a school-based program targeting the health behaviours of economically disadvantaged adolescent males considered “at-risk” of obesity. Body fat percentage (bioelectrical impedance), muscular fitness (hand grip dynamometry and push-ups), physical activity (accelerometry) and resistance training skill competency were assessed at baseline and post-intervention (i.e., 8 months). Three separate multi-level mediation models were analysed to investigate the potential mediating effects of resistance training skill competency on each of the study outcomes using a product-of-coefficients test. Analyses followed the intention-to-treat principle. The intervention had a significant impact on the resistance training skill competency of the boys, and improvements in skill competency significantly mediated the effect of the intervention on percentage of body fat and the combined muscular fitness score. No significant mediated effects were found for physical activity. Improving resistance training skill competency may be an effective strategy for achieving improvements in body composition and muscular fitness in adolescent boys.     

Accelerometer data requirements for reliable estimation of habitual physical activity and sedentary time of children during the early years - a worked example following a stepped approach

This study presents a worked example of a stepped process to reliably estimate the habitual physical activity and sedentary time of a sample of young children. A total of 299 children (2.9 ± 0.6 years) were recruited. Outcome variables were daily minutes of total physical activity, sedentary time, moderate to vigorous physical activity and proportional values of each variable. In total, 282 (94%) provided 3 h of accelerometer data on ≥1 day and were included in a 6-step process: Step-1: determine minimum wear-time; Step-2: process 7-day-data; Step-3: determine the inclusion of a weekend day; Step-4: examine day-to-day variability; Step-5: calculate single day intraclass correlation (ICC) (2,1); Step-6: calculate number of days required to reach reliability. Following the process the results were, Step-1: 6 h was estimated as minimum wear-time of a standard day. Step-2: 98 (32%) children had ≥6 h wear on 7 days. Step-3: no differences were found between weekdays and weekend days (P ≥ 0.05). Step-4: no differences were found between day-to-day variability (P ≥ 0.05). Step-5: single day ICC’s (2,1) ranged from 0.48 (total physical activity and sedentary time) to 0.53 (proportion of moderate to vigorous physical activity). Step-6: to reach reliability (ICC = 0.7), 3 days were required for all outcomes. In conclusion following a 7 day wear protocol, ≥6 h on any 3 days was found to have acceptable reliability. The stepped-process offers researchers a method to derive sample-specific wear-time criterion.     

Multivariate analyses of individual variation in soccer skill as a tool for talent identification and development: utilising evolutionary theory in sports science

The development of a comprehensive protocol for quantifying soccer-specific skill could markedly improve both talent identification and development. Surprisingly, most protocols for talent identification in soccer still focus on the more generic athletic attributes of team sports, such as speed, strength, agility and endurance, rather than on a player’s technical skills. We used a multivariate methodology borrowed from evolutionary analyses of adaptation to develop our quantitative assessment of individual soccer-specific skill. We tested the performance of 40 individual academy-level players in eight different soccer-specific tasks across an age range of 13–18 years old. We first quantified the repeatability of each skill performance then explored the effects of age on soccer-specific skill, correlations between each of the pairs of skill tasks independent of age, and finally developed an individual metric of overall skill performance that could be easily used by coaches. All of our measured traits were highly repeatable when assessed over a short period and we found that an individual’s overall skill – as well as their performance in their best task – was strongly positively correlated with age. Most importantly, our study established a simple but comprehensive methodology for assessing skill performance in soccer players, thus allowing coaches to rapidly assess the relative abilities of their players, identify promising youths and work on eliminating skill deficits in players.     

‘What on Earth are They Doing in a Racing Car?’: Towards an Understanding of Women in Motorsport

Abstract

Motorsport is an under-researched area of socio-historical study. There is particularly limited academic understanding of female involvement in the social world of motorsports. Therefore, this paper focuses on the role of the media in presenting and establishing motorsport for women. In particular, a documentary analysis of articles published by a UK national newspaper group from 1890, and a case study of an all-female UK-based motor-racing championship are used to account for gendered processes that have influenced attitudes and behaviours towards women motor racers. The motor car emerged through technological progress in an overtly masculine-dominated industrial period. Traditional assumptions and biologically deterministic attitudes towards women were used by men to position motoring and motor-racing as a male preserve. Newspaper reporting throughout the 1930s suggests an era of heightened success for women motor racers as a result of gaining access to a key resource in the form of Brooklands motor-racing circuit. Following the Second World War, there was increasing commercialization and professionalization of male-dominated motorsport, as well as renewed marginalization and trivialization of female participants within the newspapers. These processes continue to influence perceptions of women in contemporary motorsport.     

Placing wireless tablets in clinical settings for patient education

Objective

The authors explored the feasibility and possible benefit of tablet-based educational materials for patients in clinic waiting areas.

Methods

We distributed eight tablets preloaded with diagnosis-relevant information in two clinic waiting areas. Patients were surveyed about satisfaction, usability, and effects on learning. Technical issues were resolved.

Results

Thirty-seven of forty patients completed the survey. On average, the patients were satisfied in all categories.

Conclusions

Placing tablet-based educational materials in clinic waiting areas is relatively easy to implement. Patients using tablets reported satisfaction across three domains: usability, education, and satisfaction.     

Lifestyles of the Rich and Famous: Celebrity Media Diet and the Cultivation of Emerging Adults’ Materialism

The present study used cultivation theory to explore the relationships between celebrity media diet and materialism for a sample of 224 emerging adults. Results indicated main effects between both celebrity magazine consumption and celebrity TV news consumption on materialism. Total celebrity media diet was also significantly related to materialism. Findings suggest that a media diet high in celebrity culture and lifestyle has significant impact on emerging adults’ preoccupation with consumerism, particularly for women. This research contributes to a growing body of literature on the effects of a celebrity-saturated media environment and the cultivation of materialistic attitudes.     

“I Belong Here.”: Culturally Sustaining Pedagogical Praxes from an Alternative High School in Brooklyn

Despite persistent class and race inequalities in educational attainment and achievement in the U.S., hegemonic cultural ideologies and urban education politics and policies continue to proceed from an insistence that education is the great equalizer. These ideologies do not take into account the ways that normative school culture and pedagogical praxes take for granted middle-class, white-supremacist cultural assumptions that privilege student populations whose social locations already probabilize high rates of achievement and attainment. Vast research published in The Urban Review and elsewhere has demonstrated the importance and efficacy of culturally sustaining pedagogy for improving outcomes for economically marginalized students of color (Allen in Urban Rev 47(1):209–231, 2015; Delpit in Harv Educ Rev 56(4):379–386, 1995; Farinde-Wu et al. in Urban Rev 49(2):279–299, 2017; Gay in culturally responsive teaching: theory, research, and practice, Teachers College Press, New York, 2010; Graves in Berkeley Rev Educ 5(1):5–32, 2014; Jemal in Urban Rev 49(4):602–626, 2017; Ladson-Billings in Crossing over to Canaan: the journey of new teachers in classrooms, Jossey-Bass, San Francisco, 2001, The dreamkeepers: successful teachers of African American children, Jossey-Bass Publishers, San Francisco, 2009; Lee in Culture, literacy and learning: taking bloom in the midst of the whirlwind, Teachers College Press, New York, 2006; Marciano in Urban Rev 49(1):169–187, 2016; Nieto in Language, culture, and teaching: critical perspectives, Routledge, New York, 2010; Paris in Educ Res 41(3):93–97, 2012; Paris and Alim in Culturally sustaining pedagogies: teaching and learning for justice in a changing world, Teachers College Press, New York, 2017; Wiggan and Watson in Urban Rev 48(5):766–798, 2016; Yosso in Race Ethn Edu, 8(1):69–91, 2005). This article uses rich ethnographic data from a transfer school in Brooklyn, New York that serves financially insecure youth of color who are “over-age and under-credited.” These data and my analysis showcase the expertise and indigenous knowledges of teachers who practice cultural relevance and critical racial awareness in order to engage, retain, graduate and prepare students who are historically and presently marked for failure by an education system that has always been more adept at reproducing social inequality than disrupting it (Borck in Qual Inq 20(10):1–8, 2016).

     

Using Film to Increase Counselor Empathic Experiences

The early stages of empathy in counseling—emotional reaction, role-taking, and cognitive suspension—have all been largely ignored in the counselor education/psychological literature. This article describes these stages from the perspective of the aesthetic/film literatures. Emotional reaction is an internal, unobservable state of being. Role-taking involves cognitive understanding and entering the perceptual world of another. Cognitive suspension means letting go of personal beliefs and values. The film literature describes how audience emotional states are created by directors, writers, actors, and editors. This article explains how counselor educators and supervisors can use this information to help counselors increase their empathic experiences.
