ABSTRACT

Purpose: The purpose of this study was to identify whether post-resistance exercise (REx) blood flow restriction (BFR) can elicit a similar acute training stimulus to that offered by either heavy REx or traditional low-load BFR REx. Method: Ten men completed trials with 30% one-repetition maximum (1RM) for 5 sets of 15 repetitions without BFR (30%), with BFR during exercise (30% RD), and with postexercise BFR (30% RP) and at 75% 1RM for 3 sets of 10 repetitions. Lactate and cortisol were measured before and up to 60 min after exercise. Thigh circumference, ratings of perceived exertion (RPE), and pain were measured before and after exercise. Surface electromyography was measured during exercise. Results: All conditions had a large effect (effect size [ES] > 0.8) on lactate, with the largest effects observed with the 75% condition; no differences were observed between the 30% conditions. All conditions had a moderate effect (ES > 0.25 ≤ 0.4) on increasing thigh circumference. This effect was maintained (ES = 0.35) with the application of BFR after REx (30% RP). Change in RPE, from the first to last set, was significantly greater with 30% RD compared with other conditions (all p < .05). Electromyography amplitude was higher and percentage change was greater for the 75% condition compared with the other conditions (both p < .05). Conclusions: The application of BFR immediately post-REx altered several of the responses associated with REx that is aimed at inducing muscular hypertrophy. Additionally, these changes occurred with less pain and perceived exertion suggesting that this form of REx may offer an alternative, tolerable method of REx.     

Navigating Sexualization as a Sexuality Professional: Recommendations from Sexuality Educators at the 2016 National Sex Ed Conference

Sexuality professionals are likely to experience unwanted sexualization based solely on their profession. Sexuality professionals are sexualized by various groups of people including strangers, colleagues, or even friends and family. The research literature discusses how sexuality researchers experience and navigate this sexualization but includes little information about the ways in which sexuality educators are sexualized. At the 2016 National Sex Ed Conference, we facilitated a workshop for sex educators to discuss how they are sexualized and how they would suggest navigating such experiences. Through this workshop proceeding, we examine how educators echoed many of the same strategies used by sexuality researchers found in the literature along with some unique population concerns and strategies.     

Teachers as researchers in a major research project: Experience of input and output

Teachers have long participated in collaborative research. However, they have generally had direct stakes in the outcomes. Teachers in the Early Professional Learning (EPL) Project used their insider status to gather data not directly related to their own practice. Lessons for integrating a group of teacher–researchers into a major project are discussed. Some of these are practical, but also cover their unexpectedly experienced initial isolation within the project team, that has relevance for both forming and theorising communities of enquiry. An outline for a new concept of teacher–researcher begins to emerge that may influence the direction of educational research.     

From Surgeon General's bookshelf to National Library of Medicine: a brief history.

The National Library of Medicine originated as a few books in the office of the army''s surgeon general, Joseph Lovell, between 1818 and 1836. It became the nation''s largest medical library after the Civil War under the direction of John Shaw Billings and began publishing the Index-Catalogue of the Library of the Surgeon General''s Office and preparing the Index Medicus. After Billings retired in 1895, the library marked time as army medical officers were rotated through as directors until modernization began under Harold Wellington Jones during World War II. during the directorship of Frank B. Rogers (1949-1963), who introduced MEDLARS, guided the move to a new building in Bethesda, and revitalized other operations, the institution received statutory authority as the National Library of Medicine within the Public Health Service (1956). By 1965, which was marked by the passage of the Medical Library Assistance Act, the library had again regained a position of world leadership.

Parenting and the Adjustment of Children Born to Gay Fathers Through Surrogacy

Findings are presented on a study of 40 gay father families created through surrogacy and a comparison group of 55 lesbian mother families created through donor insemination with a child aged 3–9 years. Standardized interview, observational and questionnaire measures of stigmatization, quality of parent–child relationships, and children's adjustment were administered to parents, children, and teachers. Children in both family types showed high levels of adjustment with lower levels of children's internalizing problems reported by gay fathers. Irrespective of family type, children whose parents perceived greater stigmatization and children who experienced higher levels of negative parenting showed higher levels of parent‐reported externalizing problems. The findings contribute to theoretical understanding of the role of family structure and family processes in child adjustment.
