Cross-sectional comparison of body composition and resting metabolic rate in Premier League academy soccer players: Implications for growth and maturation

ABSTRACT

For the first time we aimed to: (1) assess fat-free mass (FFM) and RMR in youth soccer players, (2) compare measured RMR to estimated RMR using previously published prediction equations, and (3) develop a novel population-specific prediction equation. In a cross-sectional design, 99 males from a Premier League academy underwent assessments of body composition (DXA) and RMR (indirect-calorimetry). Measured RMR was compared to estimated values from five prediction equations. A novel RMR prediction equation was developed using stepwise multiple regression. FFM increased (P<0.05) between U12 (31.6±4.2 kg) and U16 (56.3±5.3 kg) after which no further increases occurred (P>0.05). RMR in the U12s (1655±195 kcal.day^?1), U13s (1720±205 kcal.day^?1) and U14s (1846±218kcal.day^?1) was significantly lower than the U15s (1957±128 kcal.day^?1), U16s (2042±155 kcal.day^?1), U18s (1875±180 kcal.day^?1) and U23s (1941±197 kcal.day^?1) squads (P>0.05). FFM was the single best predictor of RMR (r²=0.43; P<0.01) and was subsequently included in the novel prediction equation: RMR (kcal.day^?1) = 1315 + (11.1 x FFM in kg). Both FFM and RMR increase from 12-16 years old, thus highlighting the requirement to adjust daily energy intake to support growth and maturation. The novel prediction RMR equation developed may help to inform daily energy requirements.     

The Concerns of School Counselors‐in‐Training About Working With Children and Adolescents With HIV Disease: Training Implications

As the number of children and adolescents who have or are affected by HIV disease increases, so does the need to examine the preparation of counselors to work with this population. This study assessed (a) the knowledge, beliefs, and social comfort of school counselors‐in‐training, as related to working with this population, and (b) these students' concerns and perceptions about their preparedness. Participants reported high levels of general knowledge and positive beliefs; however, they also demonstrated deficits in specialized knowledge and discomfort in counseling situations. Participants expressed concerns about their preparation and ability to deal with grief issues. Implications for training counselors are discussed.     

Perceived Competency in Working With LGB Clients: Where Are We Now?

Lesbian, gay, and bisexual (LGB) clients use counseling services at higher rates than their heterosexual counterparts, yet current training for counselors may be inadequate. In this online study, 234 graduate counselor education and counseling psychology students completed the Sexual Orientation Counselor Competency Scale ( Bidell, 2005 ) and provided information about their training in working with LGB clients. Participants viewed themselves as more competent on the Awareness and Knowledge subscales than on the Skills subscale. Increased level of training (doctoral vs. master's), number of LGB clients seen in practica, and attendance at LGB‐focused workshops and conferences were associated with increased competence. Implications for programmatic development are discussed.     

The accountability era in US teacher education: looking back,looking forward

Abstract

In keeping with the theme of the 40th anniversary issue of EJTE, this article looks back and forward at US teacher education accountability. It argues that “holding teacher education accountable” has been the major approach to reforming teacher education in the US for the last two decades, assuming that enhanced teacher education quality depends on vigilant public evaluation and monitoring of outcomes related to teacher education institutions, programs, and teacher candidates. This article looks back at the “era of accountability” by examining five policy, political, and professional developments that contributed to its emergence and strong hold on US teacher education. Looking forward to the future of teacher education accountability in the US, the article argues that we need a new approach – democratic accountability in teacher education – which is based on intelligent professional responsibility for students’ learning including democratic knowledge and skills, strong equity, and genuine collaboration with multiple stakeholders.     

Sports nutritionists’ perspectives on enablers and barriers to nutritional adherence in high performance sport: A qualitative analysis informed by the COM-B model and theoretical domains framework

ABSTRACT

Athlete adherence to nutritional guidance is critical for optimal health and performance, yet little is known about the barriers and enablers to athletes’ dietary behaviours within high-performance sport. To advance understanding, we applied a theoretical lens derived from the Capability, Opportunity, Motivation – Behaviour (COM-B) model and the Theoretical Domains Framework (TDF) to explore the qualitative accounts of sports nutritionists. Five focus groups comprising sports nutritionists working in Olympic and Paralympic sport (n = 14), professional sport (n = 6), or both (n = 6) were undertaken. Thematic analysis was conducted and the interpretations of the findings were guided by COM-B and the TDF. To achieve nutritional adherence, the behavioural analysis identified the need to intervene across all three COM-B components and at least five associated TDF domains (e.g., decision-making processes, reinforcement, social influences, behavioural regulation and environmental context and resource). For the first time, the findings illustrate the complex interplay of the training setting with the capabilities, opportunities, and motivation of the practitioners, athletes and coaches. By applying established behavioural science theories to sports nutrition, the foundations for the development of targeted and multifaceted behavioural interventions addressing athlete dietary adherence in high-performance sport have been laid.     

Poverty reduction through entrepreneurship: Microcredit,learning and ambivalence amongst women in urban Tanzania

Microcredit strategies combine the logic of business, progressive approaches to learning from experience and the key aim to reduce poverty, especially amongst women. The focus in such interventions on the independent, entrepreneurial citizen suggests not only new ways to generate economic growth and sustainable development, but an important recalibration of the repressive social relations thought to be at the root of women's persistent ‘under-development’. This article explores women's experiences of their roles as entrepreneurs, and reflects on how the learning processes and outcomes associated with microcredit schemes ‘shape the self’, often in quite unpredictable ways. The article is based on an ethnographic study of disadvantaged women in Dar es Salaam, and follows them as they participate in NGO-based training schemes, ‘practise’ entrepreneurship in a range of income-generating settings, and negotiate the consequences of the new subjectivities on which the independent, entrepreneurial citizen is based. Like many microcredit programmes, the majority of women in the study were full time housewives before joining the scheme. Others had left their jobs following retrenchment, prejudice or gender discrimination. In all cases, they started their own businesses with little or no business experience or education. Whilst some appear to have embraced the new opportunities, others have struggled. In all cases, microcredit and the associated learning processes produced contradictory and ambivalent feelings of success and failure, hope and disappointment, progress and exclusion. The article explores these ambivalences in order to critique development initiatives that are based on universal notions of autonomy and self-determination in contexts shaped by dependence and structural inequality.     

Physiological responses and bowling performance during repeated spells of medium-fast bowling

The aim of the present study was to investigate the relationship between physiological and performance responses during repeated 6-over fast-bowling spells. Six, first-class, medium-fast bowlers performed 2x6-over spells separated by 45 min of light activity. The 6-over spells were based on the Cricket Australia fast bowling skills test that is a set order of deliveries at a grid-based target. Ball speed, accuracy and full and final 5-m run-up speed were measured on each ball. Nude mass, heart rate, core temperature, capillary blood lactate, pH and glucose, perceptual measures of RPE and muscle soreness (MS) and repeated vertical jump efforts were measured prior to, during and following each spell. Results indicated no decrement (P=0.41) and small effect sizes (d<0.2) in bowling speed (125.7+/-5.1 and 125.4+/-4.5 km.h(-1)) or accuracy (40.4+/-16.1 and 41.6+/-18.0 AU) between spells 1 and 2. No differences (P=0.6-0.8) were present between spells for heart rate, core temperature, lactate, pH, glucose, RPE, MS or vertical jump. Only final 5-m run-up speed showed a large correlation with ball speed (r=0.70), while accuracy and speed were not correlated (r=0.05). In conclusion, repeated 6-over spells in well-trained bowlers results in minimal performance decrement in mild conditions (22 degrees C). As faster bowlers had faster final 5-m run-up speeds, the maintenance of high final 5-m run-up speeds might be important to maintaining bowling speed. Future research should also include a third bowling spell and warmer environmental conditions.
