Measurement Errors in Modified Pull-Ups Testing

In a review of 46 meta-analyses of gender differences, overhand throwing had the largest gender difference favoring boys (ES > 3.0). Expectations for gender-specific performances may be less pronounced in female Australian Aborigines, because historical accounts state they threw for defense and hunting. Overhand throwing velocities and kinematics were recorded in 30 female and male Aboriginal Australian children 6-10 years old. Results indicated the Aboriginal girls and boys were more similar in horizontal ball velocities than U.S. girls and boys. Throwing kinematics between girls and boys were also more similar in Australian Aborigines than U.S. children. Aboriginal girls threw with greater velocities than U.S., German, Japanese, and Thai girls, while the boys were similar across cultures.     

Effects of Different Durations of Physical Training on Cardiorespiratory Function,Body Composition,and Serum Lipids

Abstract

The purpose of the study was to determine the effects of 15, 30, and 45 min of conditioning on maximum performance and cardiorespiratory fitness variables, body composition, pulmonary function, and serum lipids. Subjects, ages 20 to 35, were 59 inmates at a California state prison. The conditioning included running and walking and was performed three days/week at approximately 85 to 90% max HR for 20 weeks. The distance covered per exercise session was approximately 1.75, 3.25, and 5.1 miles for the 15-, 30-, and 45-min groups, respectively.

Improvements in treadmill performance time. [Vdot]O₂ max, max O₂ pulse, diastolic blood pressure, and total skinfold fat were proportional to duration of the training session; i.e., the subjects training in the longer duration sessions showed the greater improvements. The control group showed no significant change during the same period. Compared to the control group, the 15-min group made significant reductions in resting HR, total skinfold fat, percent fat, and waist girth and increases in [Vdot]O₂ max, max O₂ pulse,[Vdot]_E max, and treadmill performance time. Vital capacity, FEV_1.0, and % FEV_1.0 remained relatively unchanged in all four groups, as did serum cholesterol and triglycerides. The 45-min group improved significantly more than the 15-min group in treadmill time, [Vdot]O₂ max, max O₂ pulse, resting systolic and diastolic blood pressures, and percent fat. In general, comparisons between the 15- and 30-min groups and between the 30- and 45-min groups failed to yield statistically significant differences.     

List of Reviewers

Our purpose was to compare the effect of a periodized preparation consisting of power endurance training and high-intensity power training on the contractile properties of the quadriceps muscle and functional performances in well trained male sprinters (n = 7). After 4 weeks of high-intensity power training, 60-m sprint running time improved by an average of 1.83% (SD = 0.96; p < .05). This improvement was inversely related to an increase in maximal voluntary contraction torque (r = -.89, p < .05) and poorly correlated with changes in the contractile kinetics of the quadriceps muscle (r range from .36 to -.46). These findings suggest that sprint performance is poorly predicted by muscle intrinsic properties and that a neural adaptation appears to explain most of the observed functional adaptations.     

Physical Activity Practices in Elementary Schools and Associations With Physical Education Staffing and Training

Purpose: Authorities recommend that schools provide a variety of opportunities for students to obtain physical activity (PA) before, during, and after school. This study assessed the prevalence of several school PA practices—including measures of quantity and quality of physical education (PE)—in elementary schools and examined the associations of PA practices with school resources (PE staffing, training, and facilities). Method: Surveys were obtained from respondents in nationally representative samples of elementary schools from 2009–2010 to 2011–2012 (1,831 schools). Results: Few schools (20.8%) provided students with PE class every day, but most (76.3%) had an appropriate PE student-to-teacher ratio ( ≤ 25:1). Many schools (74.0%) offered 20 min of recess daily, but fewer than half offered organized opportunities for PA before or after school (e.g., sports). After controlling for demographics and school size, having a full-time PE teacher and requiring PE teachers to obtain PE-related continuing education (CE) were associated with PE practices such as offering ≥ 150 min of PE per week (for 3rd-grade students) and testing PE knowledge, skills, and fitness. Required CE was also associated with a higher likelihood of offering PA during the school day (i.e., activity breaks and PA outside of PE class) and before or after the school day (i.e., afterschool PA programs). Conclusion: Few schools offer a broad array of PA programming. However, PE staffing and CE are positively associated with many PA practices including those outside of PE, possibly indicating that PE staff serve a crucial role in promoting a whole-school PA-supportive environment.     

Lifestyles and gendered patterns of leisure and sporting interests among Irish adolescents

This paper strives to provide an insight into the multifaceted relationships that young people have, examining the social, cultural and institutional discourses, which shape their lives. We set out to discuss, from an empirical poststructuralist perspective, the way in which Irish adolescents write about the reality of their lives and privilege certain practices and forms of subjectivity. We are particularly interested in the role and significance of physical activity in the lives of young people, asking what institutional and cultural discourses are brought into play to construct particular identities and social practices associated with leisure and sporting interests. This paper focuses on a purposeful sample of 168 written narratives of Irish post-primary students (14–17 years of age), chosen to represent the gender of students, a range of rural and urban school locales from different geographic locations and single sex and co-educational schools. We focus on the inter-relationships between (1) family and friends; (2) community-localism and tradition; (3) commodification and globalisation; (4) popular culture; and (5) gendered patterns of leisure and sporting interests. The family is a strong focal point for these young people as are their friends and being part of a community. The young people (boys in particular) are significant consumers of ‘media sport’ and both girls and boys were knowledgeable of national and international politics. We also comment on the extent to which female and male adolescents negotiate, similarly or differently, culturally dominant discourses within physical activity and sport, with significantly more boys choosing to write about physical activity and sport in their narratives.     

‘Who’s that girl sitting with the boys?’: negotiating researcher identity in fieldwork with adolescent boys

ABSTRACT

The aim of this paper is to discuss the negotiation and performance of researcher identities while conducting fieldwork. It draws on a larger study of masculinities, health and physical education, and sport in an elite boys’ school to analyse the researcher’s role as a female ethnographer in the world of health and physical education in boys’ schooling. Using data drawn from field notes, reflections, and observations from six months of fieldwork at the school, this paper joins a growing body of research, which attests to the importance of making known the ‘hidden histories’ of qualitative research. The significance of this paper is twofold. Firstly, it lies in recognising the details of how researchers position themselves in the field, negotiate and renegotiate their identities, and the significance of social dynamics and relationships to this process. Secondly, it raises awareness of the implications of negotiating researcher identities and embodied experiences in the field and suggests this analysis should become more public in qualitative research.     

A Two-Year Longitudinal Study of Stressful Life Events, Social Support, and Social Problem-Solving Skills: Contributions to Children''s Behavioral and Academic Adjustment

We investigated the contributions of stressful life events and resources (social support and social problem-solving skills) to predicting changes in children's adjustment. At Time 1, 361 third through fifth graders completed measures of social support and social problem-solving skills. Their parents completed a stressful life events scale and a child behavior rating measure. The children's teachers provided ratings of behavioral and academic adjustment. 2-year follow-up data (Time 2) were obtained for approximately half of the sample on the same measures. Time 1 stressful life events and resources showed some significant but modest zero-order correlations with the Time 2 adjustment indices. Hierarchical multiple regressions revealed prospective effects for Time 1 social support on later teacher-rated competencies and grade-point average. In addition, increases over time in social support and social problem-solving skills (a composite score) were significantly related to improvement in behavioral and academic adjustment, whereas stressful life events were not predictive of adjustment.     

Do special education teachers use IEPs to guide instruction?

Teachers in a large urban school system were surveyed with a self-administered questionnaire and a modified nominal group technique to assess their views about IEPs and identify impediments to implementing the IEPs of their students. Teachers indicated that they viewed the IEP more as a legal requirement than as an important guide for planning instruction. Frequently they were not involved in the development of their students' IEPs. The article specifies reasons given by teachers for not adhering to their students IEPs and provides recommendations for increasing teacher involvement in IEP preparation. It also presents recommendations for improving instructional conditions and practices which may facilitate IEP implementation.     

Comparative career accomplishments of two decades of women and men doctoral graduates in education

Patterns of doctoral study and subsequent career progress were compared for 756 men and women doctoral graduates in education at a research university from two six-year periods, one before and one after a rapid nation-wide increase in the percentage of women doctorates. Despite advantages relative to men in admission, financial support and full-time study, women doctorates of both periods had achieved less career progress than men but held similarly positive perceptions concerning career impact of the degree. Work experience prior to doctoral study strongly predicted career progress for both genders. Thus, affirmative action may have positively affected the careers of recent women doctorates who were younger and who began study with less established careers than women doctorates prior to 1970.     

Heritability,Social Disadvantage and Psychosocial Intervention

To argue that anything as complex as human behaviour has multifactorial origins demanding a systems analysis is today almost a statement of the obvious. This does not, however, mean that a search for significant main effects in populations is unwarranted, provided that these can be shown in replicated studies across place and time. In this article two such effects will be examined. In both cases there is a massive amount of data available, much of it recent, and some of it based on sophisticated research designs.
