High-intensity interval and moderate-intensity continuous training elicit similar enjoyment and adherence levels in overweight and obese adults

Background: High-intensity interval training (HIIT) has been shown to improve cardiometabolic health during supervised lab-based studies but adherence, enjoyment, and health benefits of HIIT performed independently are yet to be understood. We compared adherence, enjoyment, and cardiometabolic outcomes after 8 weeks of HIIT or moderate-intensity continuous training (MICT), matched for energy expenditure, in overweight and obese young adults. Methods: 17 adults were randomized to HIIT or MICT. After completing 12 sessions of supervised training over 3 weeks, participants were asked to independently perform HIIT or MICT for 30 min, 4 times/week for 5 weeks. Cardiometabolic outcomes included cardiorespiratory fitness (VO₂ peak), lipids, and inflammatory markers. Exercise enjoyment was measured by the validated Physical Activity Enjoyment Scale. Results: Exercise adherence (93.4?±?3.1% vs. 93.1?±?3.7%, respectively) and mean enjoyment across the intervention (100.1?±?4.3 vs. 100.3?±?4.4, respectively) were high, with no differences between HIIT and MICT (p?>?.05). Similarly, enjoyment levels did not change over time in either group (p?>?.05). After training, HIIT exhibited a greater decrease in low-density lipoprotein cholesterol than MICT (?0.66?mmol?L^?1 vs. ?0.03?mmol?L^?1, respectively) and a greater increase in VO₂ peak than MICT (p?<?.05, +2.6?mL?kg?min^?1 vs. +0.4?mL?kg?min^?1, respectively). Interleukin-6 and C-reactive protein increased in HIIT (+0.5?pg?mL^?1 and +?31.4?nmol?L^?1, respectively) and decreased in MICT (?0.6?pg?mL^?1 and ?6.7?nmol?L^?1, respectively, p?<?.05). Conclusions: Our novel findings suggest that HIIT is enjoyable and has high unsupervised adherence rates in overweight and obese adults. However, HIIT may be associated with an increase in inflammation with short-term exercise in this population.     

Performance Approach,Performance Avoidance and Depth of Information Processing: A fresh look at relations between students' academic motivation and cognition

This study examines the effects of motivational approach on the recall of verbal information processed at shallow and deep levels. Two hundred students attending the same primary school were randomly assigned to either a mastery focused condition, performance approach condition, performance avoidance condition, or a control group. The participants were motivationally manipulated prior to receiving 12 stimulus words designed to be encoded at either shallow or deep levels of processing. A free recall test followed, then a cued recall test. Results indicate that students remembered more stimulus words during cued recall than free recall. Recall of verbal information was superior when processed according to the deeper (category and sentence) levels of processing. Performance approach and avoidance goals resulted in superior recall during free and cued recall, compared with a mastery goal or with the control group. The usefulness of these findings for promoting greater clarity among motivational frameworks and ideas for further research are discussed.     

When Topics are Controversial: Is it Better to Discuss Them Face-to-Face or Online?

Ten students in a graduate-level course on Historical and Policy Perspectives in Higher Education held face-to-face and online discussions on five controversial topics: diversity, academic freedom, political tolerance, affirmative action, and gender. Upon completion of each discussion, they assessed their comfort, honesty, concern for others’ feelings, similarity of feelings to others, and willingness to disagree and then compared the face-to-face and online discussions on these measures. Students’ assessments are complex and indicate that some topics did elicit feelings of discomfort, concern for others’ feelings, and willingness to disagree in the face-to-face discussions. However, despite these feelings, the majority of students continued to prefer the face-to-face discussions. Online discussions were valued to a lesser extent, but a consistent minority of students were more comfortable in that setting. The age and race of the student also created differences in responses.

Relationships between school climate,bullying and delinquent behaviours

Given that schools are, potentially, powerful sites for influencing adolescent behaviour, it is important that there is greater understanding of the psychosocial aspects of the school climate that can be leveraged for this purpose. The research reported in this article used structural equation modelling (with data from a sample of 6120 students at Australian high schools) to examine the influence of the psychosocial school-level environment on students’ self-reported experiences of bully victimisation (i.e. being victims of bullying) and engagement in delinquent behaviours. Further, we examined whether bully victimisation mediated the relationships between school climate variables and delinquent behaviours. School connectedness and rule clarity were negatively associated with both bully victimisation and delinquency (p < 0.05), and teacher support was negatively associated with bully victimisation (p < 0.01), confirming the importance of these aspects of the school-level environment. However, affirming diversity and reporting and seeking help both had positive influences on bully victimisation (p < 0.05), raising concerns about the ways in which these aspects of the school-level environment might have been promoted. Importantly, bully victimisation was found to mediate the influence of five of the six school climate constructs on delinquent behaviours (p < 0.001). This study advance our understanding of how specific aspects of the school climate influence the prevalence of bullying and delinquent behaviour, adding weight to the call for educators to actively monitor and enhance psychosocial aspects of the school climate in order to improve student behavioural outcomes.     

Linguistic diversity in a deaf prison population: implications for due process

The entire deaf prison population in the state of Texas formed the basis for this research. The linguistic skills of prison inmates were assessed using the following measures: (1) Kannapell's categories of bilingualism, (2) adaptation of the diagnostic criteria for Primitive Personality Disorder, (3) reading scores on the Test of Adult Basic Education, and (4) an evaluation of sign language use and skills by a certified sign language interpreter who had worked with deaf inmates for the past 17 years. Deaf inmates with reading scores below the federal standard for literacy (grade level 2.9) were the group most likely to demonstrate linguistic incompetence to stand trial, meaning that they probably lacked the ability to understand the charges against them and/or were unable to participate in their own defenses. Based on the language abilities and reading scores of this population, up to 50% of deaf state prison inmates may not have received due process throughout their arrest and adjudication. Despite their adjudicative and/or linguistic incompetence, these individuals were convicted in many cases, possibly violating their constitutional rights and their rights under the Americans with Disabilities Act.     

A multi-level modeling approach to investigating students’ critical thinking at higher education institutions

Twenty-first century and higher-learning skills such as critical thinking are highly desired for new college graduates entering the workplace, especially with rapid changing technology and a more globalized economy. As a result, the importance of critical thinking development at higher education institutions has increased. The purpose of this study was to examine the effect of student and institutional variables on the difference in critical thinking scores between first-year and third/fourth-year students at higher education institutions. We examined the extent to which institutional variables moderate the relationship between student variables and the critical thinking score difference. We used a multi-level modeling approach to account for the clustering of students in institutions. Results of this study showed that: (a) institutional variability accounted for 15% of the variance in estimated critical thinking scores, (b) third/fourth-year students had higher critical thinking scores as compared to their first-year peers even when controlling for college admissions score, and (c) in the final model, the main effects of college admission scores, student-faculty ratio, and percent Black/African American were statistically significant; however, retention was the only significant moderator of the relationship between critical thinking scores and class level. Implications and future research are discussed.
