The effect of exercise interventions on resting metabolic rate: A systematic review and meta-analysis

ABSTRACT

The systematic review and meta-analysis evaluated the effect of aerobic, resistance and combined exercise on RMR (kCal·day^-1) and performed a methodological assessment of indirect calorimetry protocols within the included studies. Subgroup analyses included energy/diet restriction and body composition changes. Randomized control trials (RCTs), quasi – RCTs and cohort trials featuring a physical activity intervention of any form and duration excluding single exercise bouts were included. Participant exclusions included medical conditions impacting upon RMR, the elderly (≥65 years of age) or pregnant, lactating or post-menopausal women. The review was registered in the International Prospective Register of Systematic Reviews (CRD 42,017,058,503). 1669 articles were identified; 22 were included in the qualitative analysis and 18 were meta-analysed. Exercise interventions (aerobic and resistance exercise combined) did not increase resting metabolic rate (mean difference (MD): 74.6 kCal·day^-1[95% CI: ?13.01, 161.33], P = 0.10). While there was no effect of aerobic exercise on RMR (MD: 81.65 kCal·day^-1[95% CI: ?57.81, 221.10], P = 0.25), resistance exercise increased RMR compared to controls (MD: 96.17 kCal·day^-1[95% CI: 45.17, 147.16], P = 0.0002). This systematic review effectively synthesises the effect of exercise interventions on RMR in comparison to controls; despite heterogenous methodologies and high risk of bias within included studies.     

Deep Dive into KBART

ABSTRACT

The Deep Dive into KBART preconference workshop provided a comprehensive overview of the National Information Standards Organization Knowledge Bases and Related Tools (KBART) Phase II Recommended Practice (http://www.niso.org/publications/rp/rp-9–2014/). The workshop was divided into four sections. The first provided an overview of the background, purpose, and value of KBART to all members of the information supply chain. The next section focused on the basic guidelines for effective exchange of metadata with knowledgebases, including method of exchange, data format, file naming conventions, and frequency of exchange. The remaining two sections of the workshop addressed the correct use of KBART data fields, first in relation to serials and then to monographs. Through classroom instruction, interactive quizzes, and hands-on exercises, the workshop provided in-depth coverage of all KBART data elements, with special focus on many of the most frequently asked questions about the recommended practice.     

The Perceptions of Success Inventory for Beginning Teachers: Measuring its psychometric properties

This study investigated the construction and evaluation of an instrument called the Perceptions of Success Inventory for Beginning Teachers (PSI-BT) intended to measure factors documented in research that contribute to beginning teachers’ perceptions of success. The PSI-BT was found to assess the following factors using exploratory factor analysis: (1) Administrative Support, (2) Classroom Climate, (3) Mentor Support, (4) Colleague and Instructional Resource Support, (5) Commitment, and (6) Assignment and Workload. Internal reliability, content validity, and concurrent validity were also measured in the validation process. Our findings suggest that the PSI-BT provides a reliable and valid instrument that can provide schools with valuable feedback to ensure the success of their beginning teachers.     

The Theory of Motivated Information Management and Posttraumatic Growth: Emerging Adults’ Uncertainty Management in Response to an Adverse Life Experience

This study tested the degree to which the uncertainty management process that emerging adults go through following an adverse event predicts their perceptions of posttraumatic growth. Participants included 215 emerging adults who had experienced an adverse life event within the past year. Overall, the results largely supported the theory of motivated information management, as uncertainty discrepancies positively predicted negative emotions about the adverse event, which in turn predicted outcome expectancies, but not efficacy assessments. Outcome expectancies were predictive of efficacy assessments, which in turn were predictive of a willingness to seek information about the event from a parent. Collectively, uncertainty management behaviors predicted posttraumatic growth and included significant indirect effects for uncertainty discrepancies through communication and target efficacy, respectively.     

Comparison of computed tomography and chest radiography in the detection of rib fractures in abused infants

PURPOSE: Chest radiographs (CXR) are the standard method for evaluating rib fractures in abused infants. Computed tomography (CT) is a sensitive method to detect rib fractures. The purpose of this study was to compare CT and CXR in the evaluation of rib fractures in abused infants. METHODS: This retrospective study included all 12 abused infants identified from 1999 to 2004 who had rib fractures and both CXR and CT (8 abdomen CTs, 4 chest CTs). CT exams had been performed for clinical indications, and were obtained within one day of the CXR. Studies were reviewed by two pediatric radiologists to determine the number, locations, and approximate ages of the rib fractures. A total of 225 ribs were completely (192) or partially (33) seen by CT, and the matched ribs on CXR were used for the analysis. RESULTS: The mean patient age was 2.5 months (1.2-5.6), with seven females and five males. While 131 fractures were visualized by CT, only 79 were seen by CXR (p<.001). One patient had fractures only seen by CT. There were significantly (p<.05) more early subacute (24 vs. 4), subacute (47 vs. 26), and old fractures (4 vs. 0) seen by CT than by CXR. Anterior (42 vs. 11), anterolateral (21 vs. 12), posterolateral (9 vs. 3) and posterior (39 vs. 24) fractures were better seen by CT than by CXR (p<.01). Bilateral fractures were detected more often by CT (11) than by CXR (6). CONCLUSIONS: While this study group is small, these findings suggest that CT is better than CXR in visualizing rib fractures in abused infants.     

Emerging adult women’s career role modeling and wishful identification with female TV news personalities

This study investigated how emerging adult women perceive, role model, and wishfully identify with female television news personalities (TVNPs) in the contemporary climate of social media celebrity where a male-dominated newsroom persists. Participants (n = 138, M = 19.58 years) selected TVNPs and completed survey measures of exposure, personal work values, perceived TVNP work values, and wishful identification. Participants’ perceived extrinsic and intrinsic work values of TVNPs correlated with their own work values, extrinsically and intrinsically. Exposure to TVNPs predicted greater wishful identification. The discussion explores women’s perceptions of TVNPs as they formulate career plans.     

Perceived stress,executive function,perceived stress regulation,and behavioral outcomes of adolescents with and without significant behavior problems

Despite school‐based services, adolescents with maladaptive behavior experience negative outcomes, highlighting the need for insight into factors that contribute to and escalate behavior problems during middle school—a high‐risk period. We examined how perceived school stress, stress regulation (engagement/disengagement coping, involuntary responses), and executive function of 79 middle schoolers with and without significant behavior problems were related to internalizing and externalizing behaviors. Results showed students with significant behavior problems (a) had lower executive function abilities and higher peer stress, (b) used less engagement coping, and (c) reported more maladaptive behaviors than typical peers. For all students, school‐based stress positively predicted behavior problems and use of stress regulation techniques, with group moderating effects. Involuntary responses to stress positively predicted maladaptive behaviors, whereas engagement/disengagement coping predicted internalizing behaviors only. As a mediator, engagement coping decreased the relationship between perceived stress and behavior problems. Based on these findings, we highlight important prevention and intervention areas.     

An Emotion-Based Prevention Program for Head Start Children

Empirical research shows that poor emotional competence is an early risk factor for the development of psychopathology. Numerous school-based prevention programs have been developed with the goal of decreasing behavior problems. Several of these programs include a discrete emotions component, but none of them are solely or primarily guided by emotion theory for their design and implementation. The prevention program described in this paper, the emotions course (EC), is a theoretically-coherent program based on differential emotions theory and is designed to be implemented by teachers in Head Start classrooms. Children participating in a pilot implementation of EC showed larger increases in emotion knowledge and less growth in negative emotion expression than their peers in control classrooms. These findings provide initial support for EC. Future implementations of the program need increased monitoring of implementation fidelity as well as additional methods to assess the success of the program.
