Effects of fixed vs. self-suggested rest between sets in upper and lower body exercises performance

In its last position stand about strength training, the American College of Sports Medicine recommends a rest interval (RI) between sets ranging between 1 and 3?min, varying in accordance with the objective. However, there is no consensus regarding the optimal recovery between sets, and most studies have investigated fixed intervals. Therefore, the aim of this study was to analyse the effects of fixed versus self-suggested RI between sets in lower and upper body exercises performance. Twenty-seven healthy subjects (26?±?1.5; 75?±?15?kg; 175?±?12?cm) were randomly assigned into two groups: G1: lower body exercises and G2: upper body exercises. Squat and leg press 1 repetition maximum (1RM) were tested for the G1 and bench press and biceps curl 1RM for G2. After the 1RM tests, both groups performed three sets to concentric failure with 75% of 1RM in combination with different RIs (2?min or self-suggested) on separate days and the exercises performance was evaluated by the number of repetitions. The results demonstrated no significant differences in the number of repetitions between 2?min and self-suggested RIs that presented similar reductions with the sets progression. It was also shown that the self-suggested RI spent less time recovering than the 2?min RI group on average. This suggests that for individuals with previous experience, the self-suggested RI can be an effective option when using workloads commonly prescribed aiming hypertrophy. Also, the self-suggested RI can reduce the total training session duration, which can be a more time-effective strategy.     

Thriving at the Intersection: Integrating Social Determinants of Health and Sexual Health Education to Achieve Positive Outcomes for Youth

Abstract

Social determinants of health are the key to understanding and addressing persistent disparities in adolescent pregnancy in the United States. However, there is little guidance on what concrete steps organizations can take to work at the intersection of social determinants of health (SDoH) and sexual and reproductive health (SH). Two community-based organizations completed a case study using a structured interview guide to illustrate their transition working at this intersection. The Alexandria Campaign on Adolescent Pregnancy and Identity, Inc. arrived at the intersection of SDoH and SH from opposite ends of the road. Despite clear differences in their trajectory, their experiences share four key elements that marked their success in expanding their core work: (a) both organizations enjoyed ample community and political support, (b) they used data to drive strategic decisions, (c) they used funding opportunities to move toward the intersection of sexual health and social determinants, and (d) they leveraged existing programs to sustain their efforts. Organizations working at the intersection must continuously leverage community, political, and financial capital to pursue partners, expand services, and change policies that sustain a holistic approach to youth health and well-being.     

Performance of goldfish trained in allocentric and egocentric maze procedures suggests the presence of a cognitive mapping system in fishes

Goldfish were trained to obtain food in a four-arm maze placed in a room with relevant spatial cues. Four experimental conditions were run: allocentric, egocentric, egocentric + allocentric, and control. Relative to controls, all groups were able to solve the different tasks with high accuracy after 1 week of training. Subsequent transfer tests revealed place and response strategies for allocentric and egocentric groups, respectively, and both types of strategies for the ego-allocentric group. Moreover, the allocentric group showed the capacity to choose the appropriate trajectory toward the goal, even from novel starting points, presumably by using the distal cues as a whole. The results suggest that, in addition to using egocentric strategies, goldfish are able to solve spatial tasks on the basis of allocentric frames of reference and to build complex spatial cognitive representations of their environment.     

The role of cued speech in the development of Spanish prepositions

The aim of the present study was to advance the knowledge of the linguistic development of students with prelingual profound deafness, especially the acquisition and use of prepositions in Spanish, a lexical category with an important role in the verbal comprehension. The researchers sought to learn the level of mastery students with prelingual profound deafness can achieve in the command of prepositions, depending on the system of communication they have been exposed to: classic oralism, Cued Speech, or signed language. The results show that the different systems of communication contribute, to different degrees, to the acquisition of Spanish prepositions, with the best results being obtained with Cued Speech.     

Process Versus Content: Integrating Personal Awareness and Counseling Skills to Meet the Multicultural Challenge of the Twenty‐First Century

The authors describe a study in which there was a strong relationship between personal awareness and multicultural counseling skills during group supervision. The authors suggest that during supervision, supervisors should help counselors‐in‐training to attain wisdom, as defined by F. J. Hanna, F. Bemak, and R. C. Chung (1999). This should be done by promoting personal awareness and may result in improvement in both multicultural and general counseling skills.     

So close,and yet so far: cross-racial interactions among undergraduate students in two neighboring borderland communities

This article discusses two studies on the extent and nature of cross-racial interactions (CRIs) among undergraduate students from two neighboring US–Mexico borderland communities. Of the four participating higher education institutions, two were adjacent to the US–Mexico borderline, while the other two were 45 miles away from the borderline. One study relied on survey responses from over 900 students, while the other relied on focus group data from over 30 students. The participating students were from two universities and two community colleges. Although the students shared some common experiences and attitudes, there were some marked and important differences among them. These differences made a compelling argument for localizing what diversity means and customizing efforts to foster CRIs on college campuses.     

Results or Participation?: Reconsidering Olympism's Approach to Competition

In spite of the privileged position that Olympism arguably occupies within the Olympic Movement, its understanding and implementation have been a challenging task. This is due to a lack of specificity, conceptual lacunas, and inconsistencies in the interpretation and elucidation of Olympism. One inconsistency pertains to the meaning and emphasis of results in Olympic contests. In this regard, the Olympic creed and the Olympic motto seem to send contradictory messages. This paper investigates the role that results should have in Olympic contests and, more broadly, in an enlightened sporting life. It argues that the most developed approach to the sporting and Olympic life is one in which the process of contesting and its ensuing results come together to form a meaningful unity.
