The effects of short versus long inter-set rest intervals in resistance training on measures of muscle hypertrophy: A systematic review

Although the effects of short versus long inter-set rest intervals in resistance training on measures of muscle hypertrophy have been investigated in several studies, the findings are equivocal and the practical implications remain unclear. In an attempt to provide clarity on the topic, we performed a systematic literature search of PubMed/MEDLINE, Scopus, Web of Science, Cochrane Library, and Physiotherapy Evidence Database (PEDro) electronic databases. Six studies were found to have met the inclusion criteria: (a) an experimental trial published in an English-language peer-reviewed journal; (b) the study compared the use of short (≤60?s) to long (>60?s) inter-set rest intervals in a traditional dynamic resistance exercise using both concentric and eccentric muscle actions, with the only difference in resistance training among groups being the inter-set rest interval duration; (c) at least one method of measuring changes in muscle mass was used in the study; (d) the study lasted for a minimum of four weeks, employed a training frequency of ≥2 resistance training days per week, and (e) used human participants without known chronic disease or injury. Current evidence indicates that both short and long inter-set rest intervals may be useful when training for achieving gains in muscle hypertrophy. Novel findings involving trained participants using measures sensitive to detect changes in muscle hypertrophy suggest a possible advantage for the use of long rest intervals to elicit hypertrophic effects. However, due to the paucity of studies with similar designs, further research is needed to provide a clear differentiation between these two approaches.     

Connecting Video Segments to Collaborative Learning Activities

Abstract

The article discusses how sections of a video can best be used in the instructional process by activating the minds of students and using their reactions to viewing to produce intellectual action. It gives some suggested schemes for this activity and shows how technological forces can become energies of change.     

Exploration of the DSM-5’s Autism Spectrum Disorder Severity Level Specifier and Prediction of Autism Severity

ABSTRACT

With the publication of DSM-5, clinical assessment of Autism Spectrum Disorder (ASD) has begun to follow a new dimensional framework which includes new severity specifiers. Little research has explored these severity ratings in comparison to other previously established severity indicators (e.g. ADOS-2 calibrated severity score). The current study compared parent and teacher ratings using the BASC-2 for 43 children and adolescents diagnosed with DSM-5 ASD, to contribute novel information to the BASC literature and to explore the new DSM-5 severity ratings. Linear regression analyses were conducted to determine the extent to which the DSM-5 Social Communication and Restrictive/Repetitive Behavior Severity Ratings (clinician-rated) predicted autism severity based on ADOS-2 calibrated severity scores. Furthermore, linear regressions were conducted to explore whether teacher ratings on the BASC-2 enhance parent ratings. Implications of these preliminary results for the assessment of children and adolescents with ASD are suggested.     

ENGAGING ELEMENTARY PRESERVICE TEACHERS WITH ACTIVE LEARNING TEACHING METHODOLOGIES

The main purpose of this study was to investigate the effects of active learning on preservice teachers' dignity, energy, self-management, community, and awareness (DESCA) abilities, attitudes toward teaching, and attitudes toward science. Third year preservice teachers (n = 77) from two different classes were involved in the study. One intact class was assigned as the experimental group, whereas the other intact class was assigned as the comparison group. The comparison group students received the instruction by traditional teaching, and the experimental group received instruction through an active learning paradigm. DESCA abilities and attitudes were measured before and after instruction. Results revealed that there was a significant difference favoring the active learning instruction on preservice teachers' DESCA scores; however, there was no significant difference on preservice teachers' attitudes toward teaching and science.     

Using Blackboard in Library Instruction: Addressing the Learning Styles of Generations X and Y

Studies show that recent generations of college students have a learning style with identifiable characteristics. Library instruction efforts must adapt to these learning styles. Course management software (CMS), such as Blackboard, is one resource available to academic librarians to meet the challenges posed by the "Net Generation." At Stetson University, the use of Blackboard courseware in library instruction sessions successfully addressed the unique learning styles of students.
