RESUMO

Introduction: Although Fitspiration is purportedly intended to motivate people to be fit and healthy, a body of research has demonstrated negative effects of these media in men and women. Understanding mechanisms can help create more targeted interventions aimed at mitigating the negative effects of Fitspiration. This research examined if selected implicitly or explicitly measured constructs moderated or mediated the effects of Fitspiration. The purposes were to examine the believability (finding the media truthful) of Fitspiration (study one; data from 139 women and 125 men aged 18-33 years were analyzed), the effects of Fitspiration on exercise intention (study two; data from 195 women and 173 men aged 18-30 years were analyzed), and whether these effects were moderated by exercise-related cognitive errors (negatively biased perception of exercise) or mediated by implicit (evaluative responses to stimuli) or explicit (reasoned evaluation of stimuli) attitudes. Methods: In two separate studies, self-identified men and women first completed a measure of exercise-related cognitive errors, then viewed gender-specific Fitspiration media, followed by measures of implicit attitudes, explicit attitudes, believability, and demographics. In study two, participants were randomly assigned to Fitspiration or control media conditions and also completed measures of fitspiration-related cognitive errors and intention to exercise. In the first study, one model was tested for each gender sample. It was hypothesized that implicit and explicit attitudes would be positively related to believability, and that exercise-related cognitive errors would moderate these relationships. In study two, separate models were tested with exercise-related or Fitspiration-related cognitive errors as the moderators with each gender sample. It was hypothesized that implicit attitudes, explicit attitudes, and believability would be positively related to intention, that the control media would lead to greater intention to exercise than the Fitspiration media, and that exercise-related cognitive errors and Fitspiration-related cognitive errors would moderate these relationships. Results: The majority of hypothesized relationships were not supported. A negative relationship between exercise-related cognitive errors and believability was found. Discussion: Overall, these studies identify and exclude factors that predict Fitspiration believability and the role that factors such as cognitive errors and attitudes may play in that.

RESUMO

Electrons in solids often adopt complex patterns of chemical bonding driven by the competition between energy gains from covalency and delocalization, and energy costs of double occupation to satisfy Pauli exclusion, with multiple intermediate states in the transition between highly localized, and magnetic, and delocalized, and nonmagnetic limits. Herein, we report a chemical pressure-driven transition from a proper Mn magnetic ordering phase transition to a Mn magnetic phase crossover in EuMn2P2 the limiting end member of the EuMn2X2 (X = Sb, As, P) family of layered materials. This loss of a magnetic ordering occurs despite EuMn2P2 remaining an insulator at all temperatures, and with a phase transition to long-range Eu antiferromagnetic order at TN ≈ 17 K. The absence of a Mn magnetic phase transition contrasts with the formation of long-range Mn order at T ≈ 130 K in isoelectronic EuMn2Sb2 and EuMn2As2. Temperature-dependent specific heat and 31P NMR measurements provide evidence for the development of short-range Mn magnetic correlations from T ≈ 250-100 K, interpreted as a precursor to covalent bond formation. Density functional theory calculations demonstrate an unusual sensitivity of the band structure to the details of the imposed Mn and Eu magnetic order, with an antiferromagnetic Mn arrangement required to recapitulate an insulating state. Our results imply a picture in which long-range Mn magnetic order is suppressed by chemical pressure, but that antiferromagnetic correlations persist, narrowing bands and producing an insulating state.

RESUMO

Purpose: Size inclusive physical activity settings may help mitigate the impact of physical activity-related weight stigma. In this interpretive description study, we aimed to understand how women with larger bodies experienced size inclusive physical activity settings. The study was informed by a settings-based approach to health promotion. Method: We interviewed nine women with larger bodies who participated in size inclusive physical activity and used an inductive approach to analyze the data. Findings: At the individual level, size inclusion was experienced as an enhancement of well-being, self-worth, and belonging. This was closely tied to the interpersonal level, whereby weight-neutral practices used by fitness instructors and lack of judgment from other exercisers contributed to experiences of size inclusion. At the organizational level, the organization's culture, marketing, programs, and physical spaces could enhance or limit inclusion and participation. However, weight stigma was prevalent in women's experiences outside the physical activity setting. Conclusion: We provide recommendations to improve size inclusion in physical activity settings.

RESUMO

Metal-organic frameworks (MOFs) provide exceptional chemical tunability and have recently been demonstrated to exhibit electrical conductivity and related functional electronic properties. The kagomé lattice is a fruitful source of novel physical states of matter, including the quantum spin liquid (in insulators) and Dirac fermions (in metals). Small-bandgap kagomé materials have the potential to bridge quantum spin liquid states and exhibit phenomena such as superconductivity but remain exceptionally rare. Here we report a structural, thermodynamic, and transport study of the two-dimensional kagomé metal-organic frameworks Ni3(HIB)2 and Cu3(HIB)2 (HIB = hexaiminobenzene). Magnetization measurements yield Curie constants of 0.989 emu K (mol Ni)-1 Oe-1 and 0.371 emu K (mol Cu)-1 Oe-1, respectively, close to the values expected for ideal S = 1 Ni2+ and S = 1/2 Cu2+. Weiss temperatures of -10.6 and -14.3 K indicate net weak mean field antiferromagnetic interactions between ions. Electrical transport measurements reveal that both materials are semiconducting, with gaps (Eg) of 22.2 and 103 meV, respectively. Specific heat measurements reveal a large T-linear contribution γ of 148(4) mJ mol-fu-1 K-2 in Ni3(HIB)2 with only a gradual upturn below ∼5 K and no evidence of a phase transition to an ordered state down to 0.1 K. Cu3(HIB)2 also lacks evidence of a phase transition above 0.1 K, with a substantial, field-dependent, magnetic contribution below ∼5 K. Despite them being superficially in agreement with the expectations of magnetic frustration and spin liquid physics, we ascribe these observations to the stacking faults found from a detailed analysis of synchrotron X-ray diffraction data. At the same time, our results demonstrate that these MOFs exhibit localized magnetism with simultaneous proximity to a metallic state, thus opening up opportunities to explore the connection between the insulating and metallic ground states of kagomé materials in a highly tunable chemical platform.

RESUMO

Combining neutron diffraction with pair distribution function analysis, we have uncovered hidden reduced symmetry in the correlated metallic d1 perovskite, SrVO3. Specifically, we show that both the local and global structures are better described using a GdFeO3 distorted (orthorhombic) model as opposed to the ideal cubic ABO3 perovskite type. Recent reports of imaginary phonon frequencies in the density functional theory (DFT)-calculated phonon dispersion for cubic SrVO3 suggest a possible origin of this observed non-cubicity. Namely, the imaginary frequencies computed could indicate that the cubic crystal structure is unstable at T = 0 K. However, our DFT calculations provide compelling evidence that point defects in the form of oxygen vacancies, and not an observable symmetry breaking associated with calculated imaginary frequencies, primarily result in the observed non-cubicity of SrVO3. These experimental and computational results are broadly impactful because they reach into the thin-film and theoretical communities who have shown that SrVO3 is a technologically viable transparent conducting oxide material and have used SrVO3 to develop theoretical methods, respectively.

RESUMO

Objective To assess preferred sources of information for seeking physical activity (PA), and how PA information seeking may contribute to participation in a campus PA program. Participants: Students attending a large, Western Canadian university between April 2015 and April 2018. Methods: Secondary analysis of an annual campus-wide survey. Results: Students sought PA information for general health. Females sought information about weight loss for appearances; males sought information for muscle gain for appearance. Internet and friends were primary sources of PA information. Regression analysis indicated females 2.49 (95% CI 1.98-3.13), domestic students 2.86, 95% CI (2.04-4.02), and first year students 24.88, 95% CI (18.12-34.17) were most likely to participate in a campus PA program. Only health reasons significantly contributed to participation 1.42, 95% CI (1.06-1.89). Conclusions: Emerging adults attending university may benefit from PA promotion that makes use of their preferred information sources.

RESUMO

Chemical bonding in 2D layered materials and van der Waals solids is central to understanding and harnessing their unique electronic, magnetic, optical, thermal, and superconducting properties. Here, we report the discovery of spontaneous, bidirectional, bilayer twisting (twist angle ∼4.5°) in the metallic kagomé MgCo6Ge6 at T = 100(2) K via X-ray diffraction measurements, enabled by the preparation of single crystals by the Laser Bridgman method. Despite the appearance of static twisting on cooling from T ∼300 to 100 K, no evidence for a phase transition was found in physical property measurements. Combined with the presence of an Einstein phonon mode contribution in the specific heat, this implies that the twisting exists at all temperatures but is thermally fluctuating at room temperature. Crystal Orbital Hamilton Population analysis demonstrates that the cooperative twisting between layers stabilizes the Co-kagomé network when coupled to strongly bonded and rigid (Ge2) dimers that connect adjacent layers. Further modeling of the displacive disorder in the crystal structure shows the presence of a second, Mg-deficient, stacking sequence. This alternative stacking sequence also exhibits interlayer twisting, but with a different pattern, consistent with the change in electron count due to the removal of Mg. Magnetization, resistivity, and low-temperature specific heat measurements are all consistent with a Pauli paramagnetic, strongly correlated metal. Our results provide crucial insight into how chemical concepts lead to interesting electronic structures and behaviors in layered materials.

RESUMO

OBJECTIVE: Although there exist videos and images created by Obesity Canada and similar organizations (e.g., the Rudd Center for Food Policy and Obesity), it is not known if the materials have the desired effect of reducing stigma against people with obesity and might have the opposite effect of increasing stigma. Therefore, two studies used implicit and explicit evaluations to examine the effectiveness of images and videos intended to reduce weight stigma. METHODS: Study 1 participants (N = 284; M age = 31.47 years [SD = 11.26]; 177 self-identified as women; 83 self-identified as living with obesity) completed two implicit measures (one with images of people living with obesity and the other with control images) followed by a weight stigma questionnaire. Study 2 participants (N = 308; M age = 31.54 years [SD = 11.35]; 153 self-identified as women; 59 self-identified as living with obesity) were randomly assigned to view an obesity and exercise video and images of persons with obesity, control video and images of persons with obesity, obesity and exercise video and control images, or control video and control images, followed by the implicit measures and explicit evaluation questionnaire. RESULTS: Implicit evaluations of the control images were more positive than the images of persons with obesity. Participants with no history of obesity who saw the control video and control images had lower weight stigma compared to participants in the other conditions. CONCLUSIONS: Materials created to reduce weight stigma might not be effective among people with no history of obesity themselves or via a family member or friend. Intervention and health promotion researchers may wish to investigate effects of the images in combination with other messages because simply using the nonstigmatizing images is likely not enough.

RESUMO

To better understand exercise-related cognitive errors (ECEs) from a dual processing perspective, the purpose of this study was to examine their relationship to two automatic exercise processes. It was hypothesized that ECEs would account for more variance than automatic processes in predicting intentions, that ECEs would interact with automatic processes to predict intentions, and that exercise schema would distinguish between different levels of ECEs. Adults (N = 136, Mage = 29 years, 42.6% women) completed a cross-sectional study and responded to three survey measures (ECEs, exercise self-schema, and exercise intentions) and two computerized implicit tasks (the approach/avoid task and single-category Implicit Association Test). ECEs were not correlated with the two implicit measures; however, ECEs moderated the relationship between approach tendency toward exercise stimuli and exercise intentions. Exercise self-schema were differentiated by ECE level. This study expands our knowledge of ECEs by examining their relationship to different automatic and reflective processes.

RESUMO

AIM: Most Canadian and Australian children do not meet Physical Activity Guidelines (PAG) or Screen Time Guidelines (STG). Regarding the social issue advertising believability model (SIABM), parental support for these behaviours may depend upon how believable parents find guideline messages. The aim of the study was to examine differences in parents' SIABM variables and perceived behavioural control for PAG and STG messages. METHODS: Data were collected online; 499 Canadian parents with at least one child aged 5-11 years (75.6% mothers) participated. Differences in model variables were analysed using analyses of variance. RESULTS: Parents demonstrated greater issue involvement, attitudes towards the issue, parental support attitudes and perceived behavioural control for the PAG compared to the STG (d > 0.10). Mothers believed the messages more and had more favourable attitudes towards the issues as compared to fathers (d > 0.21). CONCLUSIONS: Parents' evaluations of PAG messages and corresponding supportive behaviours were generally more positive than STG. Future messages should emphasise supportive behaviours for screen time reduction that are feasible and enjoyable for children.

RESUMO

It is unknown how lifelong digital media users such as young adult women perceive exercise information found online. A total of 141 women aged 18-30 years and residing in Canada were randomized to read either a factually incorrect or a factually correct blog article. Participants completed Go/No-Go tasks to measure automatically activated believability and evaluations and questionnaires to explicitly measure believability, affective evaluations, and intentions to exercise. Participants did not show evidence of automatically activated believability of the content found in either blog article. However, participants reading the factually correct article reported significantly greater explicit disbelief than those reading the factually incorrect article, though this did not predict intentions. Being factually correct may not be an important component of message believability. Exercise professionals need to remain aware of the content of popular online sources of information in an effort to curb misinformation.

RESUMO

BACKGROUND: Recent physical activity research is limited by intention-behavior discordance and is beginning to recognize the importance of automatic processes in exercise. The purpose of the current study was to examine the role of multidimensional exercise self-efficacy (SE), explicit-implicit evaluative discrepancies (EIEDs) for health, and appearance on the intention-behavior gap in exercise. METHODS: A total of 141 middle-aged inactive participants (mean age = 46.12 [8.17] y) completed measures of intentions, SE, and explicit and implicit evaluations of exercise outcomes. The participants were classified as inclined actors (n = 107) if they successfully started the exercise program and inclined abstainers (n = 35) if they were not successful. RESULTS: The inclined actors and abstainers did not differ on intentions to exercise; however, the inclined actors had higher coping SE and lower EIEDs for health. In addition, the coping SE (Exp [ß] = 1.03) and EIEDs for health (Exp [ß] = -0.405) were significant predictors of being an inclined actor. CONCLUSIONS: The interaction between explicit and implicit processes in regard to health motives for exercise appears to influence the successful enactment of exercise from positive intentions. As most physical activity promotion strategies focus on health as a reason to be active, the role of implicit and explicit evaluations on behavioral decisions to exercise may inform future interventions.

RESUMO

Professional sporting teams may be well-positioned to act as promoters of health behaviors given their fixture within a community, and association with physical activity, nutrition, and other healthy behaviors. Over 4 years, the Calgary Flames Sport and Entertainment Corporation in conjunction with local health promotion professionals, delivered a health promotion event to the public, The Calgary Flames Health Training Camp (FHTC) in Calgary, Alberta, Canada. The purpose of these annual events has been to inspire and encourage healthy behavior uptake and adherence. A description of the FHTC over each of 4 years (2015-2018), lessons learned, and some evaluative work done alongside the event on 2 of the 4 years. In 2017, self-report surveys were administered to event attendees to assess current health status including physical activity, socio-cognitive variables, health information preference, and intention to make healthful behavior change based on event attendance. Biometric data was collected including blood pressure, height, weight, and resting heart rate. Evaluations of the four consecutive events showed that the Calgary Flames Sport and Entertainment Corporation has an ability to attract substantial numbers of the general public to attend FHTC events. Self-report measures from 2017 suggest that already-active populations may be most interested in attending however, the events do appear to inspire attendees to consider behavioral changes for health. The events helped to identify individuals with health risks requiring medical attention but has not yet resulted in known behavior changes. Positive community health impacts may arise from collaboration between health promoters and professional sporting organizations.

RESUMO

Attentional capture by exercise-related stimuli is important for the regulation of physical activity. Attentional processing underlying this capture has been investigated with indirect behavioral measures based on reaction times. To investigate more direct measures of visual spatial attention toward physical activity (vs. inactivity) stimuli, we used eye-tracking and a visual dot probe task in 77 young adults with various level of physical activity. Reaction times to detect a dot appearing in the area previously occupied by a physical activity (vs. inactivity) stimulus were an indirect measure of attentional bias. The first picture gaze and viewing time were more direct measures of attentional orienting and attentional engagement, respectively. Pupil dilation was an indicator of arousal. Reaction times revealed a two-way interaction between the location of the dot and participants' usual level of physical activity. Only participants with a high level of physical activity more quickly detected a dot when it appeared in the area previously occupied by a physical activity stimulus. Eye-tracking results showed greater odds of first gazing at physical activity stimuli and for a longer time, and a greater decrease in pupil size when viewing physical activity stimuli when usual level of physical activity was moderate or high, but not low. The variance explained in the outcomes ranged from 13.9% (pupil dilation) to 40% (reaction times). Overall, as hypothesized, compared to less physically active participants, participants who were more physically active demonstrated indirect (reaction times) and direct (first gaze, viewing time) evidence of a more pronounced attentional bias toward physical activity. Physical activity stimuli biased attention, with a pronounced effect when the level of physical activity was higher. These findings suggest that physical activity stimuli are relevant to the current concerns of moderately and highly active individuals.

RESUMO

The literature suggests self-efficacy is a determinant of physical activity and management of Chronic Obstructive Pulmonary Disease (COPD). The purpose of this study was to (1) test the effects of two vicarious experience interventions, coping versus mastery modeling, on self-efficacy in COPD patients performing a cardiopulmonary exercise test (CPET), and (2) determine the type of self-efficacy most strongly related to physical activity in COPD patients. After a baseline assessment of self-efficacy (task, coping for exercise, coping for breathing, scheduling, and walking) and potential moderators, 120 COPD patients watched a mastery model or coping model CPET video, or received usual care verbal instructions. Then, self-efficacy was assessed, followed by a CPET, and another assessment of self-efficacy. Fitbits tracked participants' step count the week following contact. Repeated measures MANOVAs assessed the intervention effects and multiple regressions assessed the contribution of self-efficacy subtypes to step count. All self-efficacy subtypes improved in the mastery and coping conditions, although greater improvement of self-efficacy for coping with exercise barriers was observed in the coping condition. Self-efficacy did not improve in the control condition and no moderators were identified. Self-efficacy for coping with exercise barriers was the self-efficacy subtype most strongly related to step count. This research suggests modeling is a useful intervention technique to enhance self-efficacy in COPD patients, although coping models may be more beneficial than mastery models for enhancing capability beliefs during complex tasks. Future interventions in COPD patients should target self-efficacy for coping with exercise barriers.

RESUMO

BACKGROUND: This study aimed to use implicit retraining to change automatic associations between body size and physical activity (PA) in women with obesity to reduce weight bias internalisation (WBI). METHODS: A Solomon-square experimental design was used to determine the effect of a four-week online implicit retraining intervention on WBI (primary measure) and PA attitudes, self-efficacy, and self-reported behaviour (secondary measures). The intervention was a visual probe task pairing counter-stereotypical images of active individuals with obesity with positive PA-related words. In qualitative telephone interviews, a sub-sample of participants provided feedback and recommendations for using counter-stereotypical images in PA promotion. RESULTS: Women completed the intervention (n = 48) or a control task (n = 55). Results of a RM-ANOVA showed no interaction or main effect of group on WBI. A main effect of time demonstrated that both groups had reduced WBI between pre-test and post-test, through to one-week follow-up. There were no differences between groups or over time for PA attitudes, self-efficacy, or behaviour. Women who completed interviews (n = 16) discussed several benefits and drawbacks of using counter-stereotypical images. CONCLUSION: Implicit retraining did not reduce WBI but qualitative findings support the use of counter-stereotypical PA images.

RESUMO

BACKGROUND: To explore the prevalence of parental support for meeting the Canadian 24-Hour Movement Guidelines for Children and Youth, identify key interactive support profiles among the four movement behaviors, and investigate subsequent sociodemographic and social cognitive correlates of these profiles. METHODS: A sample of Canadian parents (N = 1208) with children aged 5 to 17 years completed measures of the theory of planned behavior (TPB), and support of the four child movement behaviors via questionnaire. Differences in the proportion of parents supporting these four health behaviors were explored and demographic and social cognitive (attitude and perceived control) correlates of combinations of parental support for the four health behaviors were evaluated. RESULTS: Child and youth sleep behavior had the highest parental support (73%) and moderate to vigorous physical activity support had the lowest prevalence (23%). Interactive profiles of the four movement behaviors yielded six primary clusters and comprised wide variation from parents who supported none of these behaviors (19%), to parents who supported all four behaviors (14%). These profiles could be distinguished by the age of the child (younger children had higher support) and the gender of the parent (mothers provided more support), as well as constructs of the TPB, but TPB cognitions were more specific predictors of each health behavior rather than general predictors of aggregate health behavior clusters. CONCLUSIONS: Teenagers and fathers may represent key targets for parental support intervention of the 24-Hour Movement Guidelines. Intervention content may need to comprise the underlying foundations of attitude and perceived behavioral control to change parental support while considering the unique features of each health behavior to maximize related intervention effectiveness.

RESUMO

OBJECTIVES: This exploratory research examined if breast cancer or heart disease is automatically associated with physical activity compared to fruit and vegetable stimuli; if reading messages about reducing risk of breast cancer or heart disease through physical activity and fruit and vegetable consumption would affect automatic associations; and if automatic associations were related to intentions to be physically active or consume fruit and vegetables. METHODS: Participants were 80 women who completed pretest measures of automatic associations, then read a breast cancer, heart disease, or control message, followed by posttest measures. RESULTS: There was a significant association of breast cancer-related words with fruit and vegetables compared to physical activity. Heart disease was also more strongly associated with fruit and vegetables than physical activity at pretest but not at posttest. There were no other significant findings. CONCLUSION: This research highlights that fruit and vegetables rather than physical activity are more strongly associated with perceptions of breast cancer and heart disease. Automatic associations are an attitudinal construct, and the strength of association between fruit and vegetables, rather than physical activity, indicates how messages may be processed.

RESUMO

BACKGROUND: To provide a nationwide overview of the attitudes, social pressure, perceived ability and intentions of health professionals toward exercise prescription for people living with ALS (pALS). METHODS: An online survey of physician and non-physician health professionals (HPs) working in academic ALS clinics across Canada. RESULTS: The response rate was 48% (84/176) with 30% of respondents identifying as physicians, 63% as other HPs and the remainder as administrative or research personnel. Respondents were sharply divided in their intentions to provide exercise counsel: 24% unlikely and 45% likely. Respondents with low intentions were HPs that considered this activity outside their scope of practice. Measures of intention and attitude were more positive for flexibility compared to strength and aerobic exercise. Perceptions of social pressure and ability to provide exercise counsel were significantly correlated with intention across the three exercise modes in all respondents. Qualitative themes identified as barriers to exercise prescription were lack of confidence or competence (31% physicians, 32% HP), patient tolerance (30% HP), lack of evidence (22% physicians) and lack of infrastructure (22% physicians). CONCLUSIONS: While "lack of evidence" for the benefit of exercise was a deterrent for physicians, the larger issue for all respondents was building competence and confidence in exercise prescription for pALS.

RESUMO

Objectives: To examine how public attributions for the causes and solutions of physical inactivity and individuals' self-identified political orientation are associated with support for different policy actions in addressing physical inactivity. Methods: A secondary data analysis was conducted with a sample of 2,044 Canadian adults. Two sets of 2 X 3 analyses of variance and post-hoc analyses were conducted to assess (1) the mean differences by the causes of the issue of physical inactivity (individual, or both internal and external/external) and political orientation (liberal, centrist, and conservative), and (2) responsibility for solutions (private matter, or both private and public health matter, and /public health matter) and political orientation on support for least, moderate, and most intrusive policy actions. Results: No interaction effects existed between causal attribution and political orientation on policy support, but a main effect of causal attributions for physical inactivity and political orientation was significant. Those who held internal attributions for the cause of physical inactivity showed less support for policies compared to those who held external causal attributions or both internal and external causal attributions. Conservative individuals reported the least support for all policy actions in comparison to liberal or centrist orientations. There were interaction effects between responsibility for solutions and political orientation on policy support. Conservative individuals who perceived the responsibility for solving physical inactivity as a private matter had less support for all three policy actions. Conclusions: Public acceptance of policy actions addressing physical inactivity varies by the attributions the public have regarding causes and responsibility for solving the problem, and by political orientation. Advocacy and messaging for policy implementation in the physical activity arena needs to be communicated in ways that encourage reflective and informed deliberation that is representative of the Canadian population.
