Acute cardiovascular responses to interval exercise: A systematic review and meta-analysis

ABSTRACT

Interval exercise training is increasingly recommended to improve health and fitness; however, it is not known if cardiovascular risk is different from continuous exercise protocols. This systematic review with meta-analyses assessed the effect of a single bout of interval exercise on cardiovascular responses that indicate risk of cardiac fibrillation and infarction compared to continuous exercise. Electronic databases Medline, CINAHL, Embase, Scopus and Cochrane were searched. Key inclusion criteria were: (1) intervals of the same intensity and duration followed by a recovery period and (2) reporting at least one of blood pressure, heart rate variability, arterial stiffness or function. Cochrane Risk of Bias tool and GRADE approach were used. Meta-analyses found that systolic blood pressure responses to interval exercise did not differ from responses to continuous exercise immediately (MD 8 mmHg [95% CI ?32, 47], p = 0.71) or at 60 min following exercise (MD 0 mmHg [95% CI ?2, 1], p = 0.79). However, reductions in diastolic blood pressure and flow-mediated dilation with interval exercise were observed 10–15 min post-exercise. The available evidence indicates that interval exercise does not convey higher cardiovascular risk than continuous exercise. Further investigation is required to establish the safety of interval exercise for clinical populations.     

The One and the Many: Enduring Legacies of Spearman and Thurstone on Intelligence Test Score Interpretation

ABSTRACT

Charles Spearman and L. L. Thurstone were pioneers in the field of intelligence. They not only developed methods to assess and understand intelligence, but also developed theories about its structure and function. Methodologically, their approaches were not that distinct, but their theories of intelligence were philosophically very different – and this difference is still seen in modern approaches to intellectual assessment. In this article, we describe their theories of intelligence and then trace how these theories have influenced the development and use of intelligence instruments, paying particular attention to score interpretation.

Interventions for reading difficulties: a comparison of response to intervention by ELL and EFL struggling readers

This article explores whether struggling readers from different primary language backgrounds differ in response to phonologically based remediation. Following random assignment to one of three reading interventions or to a special education reading control program, reading and reading-related outcomes of 166 struggling readers were assessed before, during, and following 105 intervention hours. Struggling readers met criteria for reading disability, were below average in oral language and verbal skills, and varied in English as a first language (EFL) versus English-language learner (ELL) status. The research-based interventions proved superior to the special education control on both reading outcomes and rate of growth. No differences were revealed for children of EFL or ELL status in intervention outcomes or growth during intervention. Oral language abilities at entry were highly predictive of final outcomes and of reading growth during intervention, with greater language impairment being associated with greater growth.     

Interactive Multimedia in Introductory Accounting: A preliminary analysis

This paper describes the development of an interactive multimedia package designed for incorporation into the teaching program for degree‐level first year accounting. The initial module forms part of a pilot study at James Cook University where interactive multimedia will form an integral part of the teaching program in accounting. This module includes four sessions, equivalent to one quarter of the semester's requirement. These sessions were trialed by students, colleagues and practitioners to assess the package's effectiveness in communicating introductory accounting concepts and enhancing the learning process. Some results of these trials are presented.     

Alexia and the neural basis of reading

Three main types of acquired reading disturbance (alexia) have been described and accepted by clinicians. Each features a group of distinct findings and each is found following damage to a separate location within the language dominant hemisphere of the brain. Many different names have been applied to these entities, but posterior alexia, central alexia, and anterior alexia appear to represent both the clinical differentiations and the basic anatomical loci. A fourth type of acquired alexia, called deep dyslexia, has recently been reported, again with separate clinical findings and a different anatomical locus postulated. By comparison of the clinical features of the four alexias with features of alexia in Oriental languages and the reading competency of the nondominant hemisphere, a hypothetical neural basis for the act of reading can be outlined.

Using Collaborative Assessment to Examine the Relationship between Self-Reported Beliefs and the Documentable Practices of Preschool Teachers

A team of researchers used a collaborative assessment protocol to compare the self-reported teaching beliefs of a convenience sample of preschool teachers (N = 57) to their documentable practices (i.e., practices that could be observed, recorded, and categorized using a deductive strategy). Data were examined from survey instruments, detailed classroom observations and time-sampling, curriculum materials, and program artifacts. Results indicated that when child-directed choice/play time, emergent literacy and language development activities were emphasized, teachers self-reported beliefs were more strongly aligned with developmentally appropriate practice (DAP) as a philosophy of practice. When consistent routines, organized classrooms, preplanned curriculum, and teacher-directed learning were the dominant behaviors, the teachers were found to report more “traditional” or academic-oriented beliefs.
