Effect of movement velocity during resistance training on muscle-specific hypertrophy: A systematic review

Currently, it is unclear whether manipulation of movement velocity during resistance exercise has an effect on hypertrophy of specific muscles. The purpose of this systematic review of literature was to investigate the effect of movement velocity during resistance training on muscle hypertrophy. Five electronic databases were searched using terms related to movement velocity and resistance training. Inclusion criteria were randomised and non-randomised comparative studies; published in English; included healthy adults; used dynamic resistance exercise interventions directly comparing fast training to slower movement velocity training; matched in prescribed intensity and volume; duration ≥4 weeks; and measured muscle hypertrophy. A total of six studies were included involving 119 untrained participants. Hypertrophy of the quadriceps was examined in five studies and of the biceps brachii in two studies. Three studies found significantly greater increases in hypertrophy of the quadriceps for moderate-slow compared to fast training. For the remaining studies examining the quadriceps, significant within-group increase in hypertrophy was found for only moderate-slow training in one study and for only fast training in the other study. The two studies that examined hypertrophy of the biceps brachii found greater increases for fast compared to moderate-slow training. Caution is required when interpreting the findings from this review due to the low number of studies, hence insufficient data. Future longitudinal randomised controlled studies in cohorts of healthy adults are required to confirm and extend our findings.     

The role of parent expectations on adolescent educational aspirations

Parental expectations have long been studied as a factor in increasing adolescent educational aspirations, often linking these expectations to parental level of education and involvement in academic endeavours. This study further explores this relationship in a statewide Midwestern sample of parents and their adolescent children. Regression analysis and independent samples t‐tests were used to predict adolescent aspirations and compare groups. Results suggest that adolescent educational aspirations can to some degree be predicted by parental expectations. Parents reported high expectations for their children despite low levels of personal educational attainment. However, these high expectations were buffered by a reported unfamiliarity with college requirements and an expressed concern about college affordability and limited awareness of financial aid opportunities. Limitations and suggestions for future research and intervention are discussed.     

The Biologizing of Cognition, Development, and Education: Approach with Cautious Enthusiasm

In our commentary, we propose the current research from the field of developmental neuroscience can be incorporated within the theoretical perspectives advocated by evolutionary psychologists and advocates of the developmental systems approach. We then describe research on memory and the relationship between spatial-temporal reasoning and mathematical abilities as examples of literatures that have benefitted from the neuroscience approach. We conclude by expressing enthusiasm for the recent neuroscience findings, but caution that developmental neuroscience's focus on infancy and preschool children should not result in an overemphasis on early development and education at the expense of later development and education.     

Is This the Other Within Me? The Varied Effects of Engaging in Interfaith Learning

Abstract

Interfaith education appears to have a strong potential for prejudice reduction and for overcoming Islamophobia and antisemitism. Common in-group identity theory contends that awareness of interreligious similarities would reduce intergroup streotypes and anxiety. However, optimal distinctiveness theory assumes that pointing to similarities would actually pose an identity threat to learners, especially members of a minority. Jewish and Muslim Israeli adolescents who studied about similarities and inter religious influences between Islam and Judaism showed varied and contradictory reactions. Jewish students decreased prejudice while Muslim students slightly increased them. Findings are discussed in light of above theories, and point to educational implications.     

Assessing journal author guidelines for systematic reviews and meta-analyses: findings from an institutional sample

Objectives:Systematic reviews and meta-analyses (SRs/MAs) are designed to be rigorous research methodologies that synthesize information and inform practice. An increase in their publication runs parallel to quality concerns and a movement toward standards to improve reporting and methodology. With the goal of informing the guidance librarians provide to SR/MA teams, this study assesses online journal author guidelines from an institutional sample to determine whether these author guidelines address SR/MA methodological quality.Methods:A Web of Science Core Collection (Clarivate) search identified SRs/MAs published in 2014–2019 by authors affiliated with a single institution. The AMSTAR 2 checklist was used to develop an assessment tool of closed questions specific to measures for SR/MA methodological quality in author guidelines, with questions added about author guidelines in general. Multiple reviewers completed the assessment.Results:The author guidelines of 141 journals were evaluated. Less than 20% addressed at least one of the assessed measures specific to SR/MA methodological quality. There was wide variation in author guidelines between journals from the same publisher apart from the American Medical Association, which consistently offered in-depth author guidelines. Normalized Eigenfactor and Article Influence Scores did not indicate author guideline breadth.Conclusions:Most author guidelines in the institutional sample did not address SR/MA methodological quality. When consulting with teams embarking on SRs/MAs, librarians should not expect author guidelines to provide details about the requirements of the target journals. Librarians should advise teams to follow established SR/MA standards, contact journal staff, and review SRs/MAs previously published in the journal.     

Reclaiming Our Roots: The Influences of Media Curriculum on the Natural Hair Movement

This article, theoretically constructed on Gramsci's notion of cultural hegemony, explores the use of Black female hair as a cultural signifier in two media texts, specifically Adrienne Kennedy's play, Funnyhouse of a Negro, and Chris Rock's documentary, Good Hair, in specific media texts. Analysis of the verbal and visual rhetoric regarding a Black female aesthetic revealed associated themes of generational family influences and identity formation.     

Innovation in Practice: Preparing Doulas to Support Cesarean Births

Despite growing initiatives to support patient-centered labor and birth care, implementation of this care in the operating room is still limited. Doulas can be utilized in the operating room to facilitate evidence-based practices such as skin-to-skin contact for patients and newborns during cesarean birth. This article evaluates a curriculum and training method that was developed to educate doulas to provide safe and effective care during the cesarean birth experience. This intervention was found to be effective at improving doulas'' self-perceived confidence in skills essential to support cesarean births and may serve as a model for other institutions to address barriers to the implementation of patient-centered evidence-based care in the operating room.
