Affective responses to 10-minute and 30-minute walks in sedentary,overweight women: Relationships with theory-based correlates of walking for exercise

ObjectivesThe purpose of this study was to examine affective responses to 10-min and 30-min walks among sedentary, overweight women. Secondary purposes were to: a) examine differences in theory-based correlates of future participation in walking for exercise; and b) determine if the affective responses were related to these correlates.Design/MethodsTwenty-three sedentary, overweight women (M age = 26.62 years; BMI = 33.53 kg/m²) completed 10-min walk, 30-min walk, and quiet rest (QR) control conditions. Affective responses were assessed prior to, during, and following each condition. Self-efficacy and intention for regular participation in multiple 10-min walks or single 30-min walks for exercise during the next month were also assessed post-exercise.Results/ConclusionsAnalyses revealed that improvements in affective responses (p < 0.05) emerged during and following both walking sessions while no benefits were observed with QR. Self-efficacy (p < 0.01) and intention (p < 0.01) to walk for exercise in the future were significantly higher for multiple 10-min walks. Correlation analyses demonstrated that affective responses were most strongly and consistently correlated with intention and self-efficacy for future participation following the 10-min walk. These findings demonstrate that, while both walks resulted in similar affective benefits, sedentary, overweight women reported greater intention and self-efficacy to participate in multiple brief walks for exercise in the future.     

Modulation of brain oscillations during fundamental visuo-spatial processing: A comparison between female collegiate badminton players and sedentary controls

ObjectivesThe present study aimed to investigate the difference in fundamental cognitive processing and neural oscillations between badminton players and sedentary controls.DesignA cross-sectional design was adopted to address this issue.MethodsWe compared time-frequency electroencephalographic (EEG) activity from collegiate female badminton players (n = 12, aged 20.58 ± 2.75 years) and age-and gender-matched sedentary non-athletic controls (n = 13, aged 19.08 ± 2.10 years) when they performed a task that involves visuo-spatial attention and working memory.ResultsWe observed that players responded faster than controls on the task without suffering any increase in error responses. Correspondingly, the players, relative to controls, exhibited higher task-related modulations in beta power in the attention condition as well as in theta and beta power in the working memory condition. Notably, the behavior-EEG correlations revealed that better attention performance is associated with lower beta power, while greater working memory is related to higher theta power.ConclusionsOur results shed light on the mechanisms of athletic superiority in fundamental cognitive functioning: the higher theta synchronization points to a greater engagement of attention, whereas the higher beta desynchronization supports the contribution of processing speed (or motor-related processing) to better performance in athletes. This study extends current understanding by suggesting that enhanced neurocognitive function seen in athletes may transfer to fundamental tasks, giving insight into the generalizability of sport experience to neurocognitive functioning.     

Exercise attitudes and behaviours among retired female collegiate athletes

ObjectivesThe present study explored exercise attitudes and behaviours among retired female collegiate athletes.DesignA survey design incorporating both closed and open-ended questions was adopted.MethodA total of 218 former NCAA Division I female athletes (n = 144 gymnastics; n = 74 swimming/diving) provided details on their current exercise behaviours and their thoughts regarding exercise since retiring from collegiate sport.ResultsNo relations were found between years since retirement and athletes’ current exercise frequency, types of exercise activities, and reasons for exercising. Despite reporting activity levels consistent with recommendations (5 days/week, 1 h per session), retired athletes remained dissatisfied with their activity levels and struggled to integrate exercise alongside occupational, academic and social demands.ConclusionsAthletes may require support in adapting to an independent and less intense exercise regime on retirement. Future research may look to explore exercise attitudes and behaviours among retired athletes from a longitudinal perspective.     

Exercise training and health-related quality of life in generalized anxiety disorder

ObjectiveTo quantify the effects of six-weeks of resistance (RET) and aerobic exercise training (AET) on quality of life (QoL) among sedentary women with Generalized Anxiety Disorder (GAD).DesignData from our published randomized controlled trial of the effects of six-weeks of either RET or AET among GAD patients were analyzed.MethodThirty women with GAD were randomized to either six weeks of twice-weekly lower-body weightlifting or cycling, or wait-list control (WL). SF-36 subscales assessed dimensions of QoL. Hedges’ d effect sizes (95%CIs) quantified the magnitude of change in response to exercise training compared to WL.ResultsRET significantly improved role-physical (d = 1.04; 95%CI: [0.11–1.97]), role-emotional (d = 0.96; [0.04–1.89]), and mental health (d = 1.05; [0.11–1.98]). AET resulted in significant improvements in physical function (d = 1.31; [0.34–2.27]) and vitality (d = 0.93; [0.01–1.85]).ConclusionsExercise training improves dimensions of QoL among GAD patients. The largest effects were observed for role impairments, physical function, vitality, and mental health.     

Women who use exercise as a compensatory behavior: How do they differ from those who do not?

ObjectivesThis research examined group differences between women who reported using exercise as a compensatory behavior (ECB; n = 73) and women who did not report using exercise as a compensatory behavior (NECB; n = 133) on alcohol and exercise behavior, drinking and exercise motivation, and several related constructs.DesignA cross-sectional design was used.MethodsUndergraduate women (M age = 19.5 years, SD = 3.01 years) completed self-report measures regarding their alcohol use, alcohol-related problems, exercise behavior, alcohol and exercise motivations, impulsivity, body dissatisfaction, and dietary restraint.ResultsResults indicated that women in the ECB group reported consuming more alcohol, more binge drinking episodes, more alcohol-related problems, higher alcohol and exercise motivations, more exercise, and greater impulsivity, body dissatisfaction, and dietary restraint than women in the NECB group (p's ranging from <.0001 to .017).ConclusionsInterestingly, women who use exercise as a compensatory behavior consumed higher amounts of alcohol, but did not drink more frequently than women who did not use exercise as a compensatory behavior. Women who use exercise as a compensatory behavior also endorse drinking and exercise motives more strongly than women who did not use exercise as a compensatory behavior.     

Pitching and clutch hitting in Major League Baseball: What 109 years of statistics reveal

ObjectivesTheory on performance under pressure in sport has proposed that an athlete may be disrupted psychologically when distracted, or when explicitly monitoring too much the skills involved (Beilock & Carr, 2001; Masters, 1992). Research has also suggested that the extent to which an athlete allows pressure to impact performance may be greater for skills of increased complexity, such as hitting a baseball (Kinrade, Jackson, Ashford, & Bishop, 2010; Masters, Polman, & Hammond, 1993). Accordingly, hypotheses for the current study were that baseball hitters would be more susceptible to pressure-induced performance changes than pitchers, whose skills are less based in hand-eye coordination.Design & methodAn archival design was employed, accounting for 109 years of historical baseball data at both the team and individual levels.ResultsIn line with hypotheses, for players with a minimum of 10 postseason innings pitched in a single year (n = 835) pitching statistics were significantly correlated from regular season (less pressure) to postseason (more pressure). For those with a minimum of 20 postseason at bats in a year (n = 1731), hitting statistics were similarly correlated from season to postseason; overall, however, the weakest such relationship was batting average. For teams (n = 370), regular season pitching was expected to be the best predictor of postseason success rates; this hypothesis was supported, but only for the most recent era of baseball history (1995–2011).ConclusionsThe data imply that, while hitting should not be wholly neglected, a successful, clutch baseball team should be built primarily around pitching.     

Self-compassion and women athletes' responses to emotionally difficult sport situations: An evaluation of a brief induction

ObjectivesTo examine self-compassion as a way to promote healthy responses in women athletes when faced with emotionally difficult sport-specific situations.DesignPhase I, cross-sectional; Phase II, experimental.MethodsIn Phase I, participants (N = 101; M_age = 20.0, SD = 2.8 years) completed measures of self-compassion, self-esteem, and narcissism, as well as reactions, thoughts, and emotions in response to hypothetical (i.e., responsible for a team loss) and recalled scenarios. Participants returning for Phase II were randomly assigned to a brief self-compassion induction (n = 21), self-esteem induction (n = 20), or writing control (n = 18) group. Following the induction, they responded to the same hypothetical scenario as in Phase I.Phase I resultsAfter partialling out self-esteem and narcissism, self-compassion was related (p < .01) to negative affect (r = −.40), catastrophizing thoughts (r = −.30), personalizing thoughts (r = −.32), and behavioral equanimity (r = .28) for the hypothetical scenario. A similar pattern was found for the recalled scenario.Phase II resultsA MANOVA with Phase I self-compassion, self-esteem, and narcissism as covariates resulted in a non-significant group by time interaction, Wilks' Lambda = .75, F(12,96) = 1.27, p = .25. Follow-up hierarchical regression analysis showed Phase I levels of self-compassion as the only significant predictor for negative affect, personalizing thoughts, and behavioral equanimity.ConclusionsWomen athletes with higher self-compassion levels generally responded in healthier ways to emotionally difficult hypothetical and recalled situations in sport than their less self-compassionate counterparts. However, future research needs continued focus on evaluating self-compassion inductions and interventions for use in sport.     

Testing mediator variables in a physical activity intervention for women with type 2 diabetes

ObjectivesA limited understanding of the mechanisms of behavior change has hindered the development of more effective interventions. The aim of this study was to identify potential mediators of objectively measured physical activity (PA) behavior change in women with type 2 diabetes (T2DM).DesignMediation test of a randomized controlled trial.MethodWomen with T2DM (n = 93) from the control group (standard PA materials, n = 44) and the full intervention group (control + stage-matched printed material and telephone counseling, n = 49) of a larger PA intervention trial were included. PA outcomes were minutes of MET weighted moderate and vigorous PA/week (self-report) and steps/3-days (objective) recorded at baseline and 12-months. Social-cognitive constructs were measured and tested in a mediating variable framework.ResultsPerceived behavioral control and barrier self-efficacy mediated intervention effects on objective PA (proportion of intervention effect mediated = 18% and 24% respectively). Intention was a mediator of objective PA (23%).ConclusionPerceived behavior control, barrier self-efficacy, and intention are effective mechanisms of PA behavior change in women with T2DM.     

Cognitive-Behavioral and Personal Construct Therapies for Depression in Women with Fibromyalgia: A Randomized Controlled Trial

Background/ObjectiveFibromyalgia is a chronic pain syndrome that depressive symptoms can aggravate. The aim of the present study was to test the efficacy of Personal Construct Therapy (PCT), an approach that emphasizes identity features and interpersonal meanings as the focus of the treatment of depressive symptoms, in women with fibromyalgia.MethodWe compared PCT with Cognitive Behavioral Therapy (CBT) in a multicenter parallel randomized trial. Women with fibromyalgia and depressive symptoms (n = 106) were randomly allocated to CBT (n = 55) or PCT (n = 51) in individual and modular formats to adjust to their needs. Analysis was by linear mixed-effects models.ResultsParticipants in both conditions had significantly reduced depressive symptoms, and we found no significant difference when comparing groups both post-treatment (β = -0.47, t = -0.49, p = .63) and at follow-up (β = -1.12, t = -1.09, p = .28). Results were similar between conditions for anxiety, fibromyalgia's impact, and the distribution of clinically significant changes in depressive symptoms and pain.ConclusionsPCT and CBT seem to be equally effective in the treatment of depressive symptoms, making PCT a viable alternative treatment.     

The applicability of self-regulation theories in sport: Goal adjustment capacities,stress appraisals,coping, and well-being among athletes

ObjectivesWe examined a model, informed by self-regulation theories from the health psychology literature, which included goal adjustment capacities, appraisals of challenge and threat, coping, and well-being.DesignProspective.MethodsTwo-hundred and twelve athletes from the United Kingdom (n = 147) or Australia (n = 65), who played team (n = 135) or individual sports (n = 77), and competed at international (n = 7), national (n = 11), county (n = 67), club (n = 84), or beginner (n = 43) levels participated in this study. Participants completed measures of goal adjustment capacities and stress appraisals two days before competing. Athletes also completed coping and well-being questionnaires within 3 h of their competition ending.ResultsThe way an athlete responded to an unattainable goal was associated with his or her well-being in the period leading up to and including the competition. Goal reengagement positively predicted well-being, whereas goal disengagement negatively predicted well-being. Further, goal reengagement was positively associated with challenge appraisals, which in turn was linked to task-oriented coping, and task-oriented coping positively associated with well-being.ConclusionWhen highly-valued goals become unattainable, consultants and coaches could encourage athletes to generate alternative approaches to achieve the same goal or help them develop a completely new goal in order to promote well-being among athletes.     

Exercise is medicine… when you enjoy it: Exercise enjoyment,relapse prevention efficacy,and health outcomes for youth within a drug and alcohol treatment service

ObjectiveEvidence for the effectiveness of exercise as therapy for youth substance use disorder (SUD) is scarce. In this study, we investigated associations between exercise enjoyment and recovery outcomes for youth undergoing residential SUD treatment.MethodUsing ecological momentary assessment, each week participants reported perceptions of exercise enjoyment, relapse prevention efficacy, self-esteem, and physical health, and associations between these variables were assessed at both between- and within-person levels. There were 97 participants (age: M = 17.5, SD = 1.57, range = 14 to 21; 37 female, 60 male), with a final sample of 64 due to participants (n = 33) discontinuing treatment within 2 weeks of commencement. Of the remaining sample, 50% (n = 32) completed 3 or more assessments, 40% (n = 26) completed 5 or more, and 25% (n = 16) completed 7 or more.ResultsRelapse prevention efficacy, self-esteem, and perceived physical health increased over time in the program. Youth who, on average, enjoyed exercise more had higher self-esteem, perceived physical health, and relapse prevention efficacy than those who enjoyed it less. Additionally, on occasions when youth enjoyed exercise more (relative to their own average), they reported higher self-esteem, perceived physical health, and relapse prevention efficacy than on occasions when they reported enjoying it less.ConclusionParticipation in—and importantly, enjoyment of—exercise was linked to key health indices and predictors of relapse for youth during SUD treatment. These findings demonstrate that participation in enjoyable structured exercise may provide an important component of successful SUD treatment.     

Utilizing driving simulators for persons with multiple sclerosis: A scoping review

ObjectiveThis scoping review synopsized and mapped the evidence on the utility of driving simulators for drivers with Multiple Sclerosis (MS) including participant characteristics (e.g., demographic, clinical) suited to simulator use; and driving scenario environments, maneuvers, and outcomes reflective of driving performance.Data SourcesThe research team searched six databases for English studies on driving simulator performance in drivers with MS.Study SelectionFour reviewers independently screened 976 unique titles, 148 abstracts, and 18 full-text sources for study inclusion or exclusion. Inclusion criteria ensured that studies utilized measures of driving simulator performance in adults 18 years or older with MS.Data ExtractionReviewers independently charted, verified, and achieved consensus on 100% of the data in the extraction table.Data SynthesisThe scoping review included thirteen studies (twelve assessment, one intervention), published between 2001 and 2021. Studies included small samples (N = 11–50) of adults (M age = 36–50 years; 40–91% female), mostly with a relapsing-remitting (53–100%) diagnosis and low to moderate physical disability (Expanded Disability Status Scale score < 6.0). The assessment studies utilized driving scenarios to assess pre-driving (n = 1) or driving abilities (n = 2), responses to hazardous events in suburban (n = 1) or urban environments (n = 4), or the ability to maintain speed or lateral lane positioning during monotonous highway drives (n = 7), with four scenarios also including responses to secondary divided attention tasks. The intervention study utilized driving simulation as a training program to improve driving-related skills.ConclusionsThe evidence on the utility of driving simulators for adults with MS is limited to assessment of driving performance, mostly during monotonous highway drives. Further research should consider exploring how driving simulators can be utilized to assess driving performance in other environments or for intervention. Gender should be examined to support gender diverse populations.     

Interactive effects of video,priming, and music on emotions and the needs underlying intrinsic motivation

ObjectivesEmotions can enhance motivation towards a particular goal (Brehm, 1999), while activation of human motivation does not necessarily involve conscious processes (Bargh, 1990). The main purpose of the present study was to explore the impact of video, priming, and music on a range of emotion- and motivation-related variables, while the secondary purpose was to conduct a cross-cultural comparison.DesignA randomized controlled design was employed to address the interactive effects of video, priming, and music on emotions and motivation with reference to the circumplex theory of emotion.MethodsParticipants comprised a convenience sample of 210 volunteers (English, n = 128; M = 20.0, SD = 4.7 years; Male, n = 65; Female, n = 63; Greek, n = 82, M = 23.3, SD = 2.4 years; Male, n = 59; Female, n = 23). A control condition and five experimental conditions were presented to participants in a counterbalanced order. The needs underlying intrinsic motivation were accessed using the Activity Feeling-state Scales (AFS; Reeve & Sickenius, 1994), while emotional states were assessed using adjectives from the Circumplex Model of Affect (Russell, 1980).ResultsFindings showed that music had positive effects on emotional states and the psychological needs underlying intrinsic motivation. They also highlighted the positive effects of priming as a psychological intervention – particularly when presented through video and coupled with music.ConclusionsThe study presents the state-of-the-art for the use of video, priming, and music in sport and includes recommendations for sport psychology practitioners and researchers.     

Personal values and unsanctioned aggression inherent in contact sports: The role of self-regulatory mechanisms,aggressiveness, and demographic variables

IntroductionTo date, research-examining factors related to the sociocognitive self-regulatory mechanisms governing unsanctioned aggression have received scant attention in applied sport psychology.ObjectiveA mediating model as influenced by various demographic variables was applied to explore the relationships between athletes’ personal values and their unsanctioned aggression directly and indirectly through the mediating role of resistive self-regulatory efficacy, moral disengagement, and aggressiveness.MethodA sample of 301 French competitors of different age (young: n = 200 and adult: n = 101), gender (male: n = 172 and female: n = 129), type of sport (high: n = 131 and low contact: n = 170), level of competition (beginner: n = 115, intermediate: n = 110, and advanced: n = 76), and length of practice (brief: n = 109, intermediate: n = 49, and extensive: n = 143) completed a questionnaire assessing the aforementioned variables.ResultsStructural equation modelling demonstrates that self-transcendence and self-enhancement values have only indirect negative and positive effects, respectively, on unsanctioned aggression through the full mediating effect of the mediators. Also, age, gender, and type of sport were predictive only of some personal values and mediators.ConclusionThese findings offer evidence that resistive self-regulatory efficacy, moral disengagement, and aggressiveness are mediators that fully govern the impact of athletes’ personal values and certain demographic variables on their unsanctioned aggression. Several limitations, implications and suggestions for further research are discussed.     

Obsessive beliefs and uncertainty in obsessive compulsive and related patients

Background/objectiveThe aim of the present study was to examine obsessive beliefs and intolerance of uncertainty differences among patients Obsessive compulsive disoreder (OCD), trichotillomania, excoriation, generalized anxiety disorder (GAD) and a control group healthy.Method130 participants between the ages of 17 and 62 years (Mean = 29.56, SD = 11.81) diagnosed with OCD (n = 36), trichotillomania (n = 18), excoriation (n = 17), GAD (n = 31) and a healthy control group (n = 28) were evaluated by Obsessive Beliefs Spanish Inventory-Revised and Intolerance of Uncertainty Scale.ResultsThe trichotillomania group presented one of the highest obsessive beliefs highlighting over-importance of thoughts, thought action fusion-moral, importance of controlling one's thoughts. The OCD group also had higher scores in inflated responsibility and thought action fusion-likelihood. The GAD group excelled in inhibitory and prospective uncertainty. The level of depression influenced obsessive beliefs while anxiety affected inhibitory and prospective uncertainty.ConclusionsCognitive variables such as obsessive beliefs and Intolerance of Uncertainty should be considered in the prevention and intervention of obsessive and anxiety disorders.     

Analysis of early representations and personality among victims of domestic violence

IntroductionThis exploratory study analyses the individual elements of the victims of domestic violence through life events, early dysfunctional representations and personality.ObjectivesThis research aims, firstly, to show the existence of early traumatic experiences for the victims of domestic violence. Secondly, it aims to measure the prevalence of early maladaptive schema and identify personality traits in these subjects. Finally, our aim is to highlight that depending on the violence carried out within the couple (reciprocal/unilateral), activated schemas and personality traits are different.MethodOur sample consists of 80 female subjects, non-abused women (n = 40) and victims of domestic violence (n = 40), of which 22 victims of unilateral violence and 18 victims of reciprocal violence. Participants filled out an initial questionnaire as well as the scales and self-report questionnaires as follows: Life events (Amiel-Lebigre, 1984); TCI (Cloninger et al., 1993); YSQ-S3 (Young et al., 2005). The data were subject to statistical analysis and were processed using the software SPSS 22.ResultsThe results show that the victims have experienced more early traumas than non-victims, that schemas (emotional deprivation, mistrust and abuse, subjugation, self-sacrifice) are more active. We note also different personality traits according to the different groups (victims/non-victims) and subgroups (reciprocal violence/unilateral violence).ConclusionOur study sheds light on the role of the individual elements of the victims on the perception of the relationship and on the process of engagement and disengagement of women in abusive relationships. Limits and expectations of the study are discussed.     

Patterns in perceived crash risk among male and female drivers with and without substantial cycling experience

Perceived risk of crashes is generally higher in female than in male cyclists. No study has assessed whether these gender differences only apply to riding bicycles. Using an online risk assessment task and survey, this study (a) tested the hypothesis that compared to men, women perceive higher risks, irrespective of traffic mode and (b) explored gender differences in the predictors of perceived risk. Data were analysed from 595 driver licence holders in Australia: 444 who cycled regularly, termed ‘cyclists’ from here on (31% women) and 151 regular drivers who did not (63% women), who are referred to as ‘drivers’. Cyclists in their role as cyclists and drivers in their role as drivers (traffic role) were instructed to imagine being in a specified traffic scenario and to assess crash likelihood. Each of 6 traffic scenarios was presented twice but differing in configuration: a violating car and a violating bicycle. A mixed ANOVA, with rated probability of a crash as the dependent variable, gender and traffic role as grouping factors, and configuration as the repeated measure, resulted in a main effect of configuration, showing that both drivers and cyclists perceived higher levels of risk of violating cars than of violating bicycles (η_p2 = 0.34). The interaction of traffic role and configuration showed this difference to be smaller for drivers than for cyclists (η_p2 = 0.18). This suggests that drivers are aware of the car’s high injury potential in crashes with cyclists. The main effect of gender showed that irrespective of traffic role, women perceived higher risk than men, which supported the hypothesis that gender differences are not limited to cycling (η_p2 = 0.03). The main effect of traffic role was not significant.For the predictors of perceived risk, ANOVA showed main effects for traffic role and gender, with small effect sizes (from η_p2 = 0.02 to η_p2 = 0.03). Cyclists were more confident, less inattentive and more in favour of stricter laws. Women felt less skilled and were more concerned about risks. None of the interactions between gender and traffic role were significant, which lent further support to the hypothesis that gender differences were a general rather than a cycling specific characteristic. Thus, perceived risk does not differ between women who regularly cycle and those who do not. These findings may inform interventions about the role of perceived risk in the uptake of cycling.     

Clinical functioning and cutoff of eccentricity dimension with psychiatric patients and non-patients

ObjectivesThis study investigated the Eccentricity scale's clinical functioning from the Dimensional Clinical Personality Inventory 2 (IDCP-2). Additionally, we sought to establish a cutoff for a screening scenario to be taken as the first indicator of Eccentricity characteristics’ possible clinically relevant functioning.MethodIn total, 2167 adults, aged from 18 to 90 years (M = 28.98, SD = 11.12), being 1244 women (63%), and the majority of undergraduate students (67.9%). Total sample was comprised into five groups, namely, outpatients diagnosed with both schizotypal and schizoid PDs (n = 3), outpatients diagnosed with schizotypal PD (n = 5), outpatients diagnosed with schizoid PD (n = 2), outpatients diagnosed with other PDs and clinical disorders (n = 172), and a general population-based sample (n = 1985). Not all participants answered all the items from IDCP-2; therefore, we used the equating procedure.ResultsThe groups were statistically different in ANOVA. For the −0.40 cutoff in the theta metric scale, equivalent to a total score of 38, the area under the curve was equal to 0.85, reaching 90% of sensitivity and 87.4% of specificity.ConclusionsFindings provide clinical data on the Eccentricity scale, supporting its professional use in a clinical setting; specifically, we suggested a clinical cutoff to the scale, helping the professional address typical characteristics from schizoid schizotypal functioning.     

Effects of a single bout of moderate-to-vigorous physical activity on executive functions in children with attention-deficit/hyperactivity disorder: A systematic review and meta-analysis

ObjectivesThe aim of this study was to systematically review the literature investigating the acute effects of moderate-to-vigorous physical activity (MVPA) on executive functions (EFs) in children with attention-deficit/hyperactivity disorder (ADHD) and perform a meta-analysis of the effects of MVPA on task components that require lower and higher EF demand in this population.MethodsThe systematic review and meta-analysis followed the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. Six electronic databases, i.e., PubMed, Scopus, Web of Science, Embase, SPORTDiscus, and Education Resources Information Center (ERIC), were searched for eligible studies. Random-effects weights were used to pool the effect sizes. Publication bias was assessed by Egger’s regression test and Rosenthal’s fail-safe N. This study is registered on PROSPERO, number CRD42020184082.ResultsThe electronic database search yielded 12 studies, which met the inclusion criteria, comprising a total of 375 participants. Eleven studies with data from 275 participants were included in the meta-analysis to examine the acute effects of MVPA on tasks with lower and higher EF demand. A single bout of MVPA had a small positive effect on tasks with lower (n = 10, g = 0.32, 95% CI = 0.123–0.517) and higher (n = 10, g = 0.25, 95% CI = 0.13–0.371) EF demand. No publication bias was found.ConclusionsA single bout of MVPA may have a general facilitative effect on cognition, indicating that acute MVPA may be a transient nonpharmacological adjunctive treatment for childhood ADHD.     

Feasibility of a Self-Determination Theory-based exercise intervention promoting Healthy at Every Size with sedentary overweight women: Project CHANGE

ObjectivesTo examine feasibility, acceptability and preliminary results of a Self-Determination Theory (SDT) -based exercise intervention with a Healthy at Every Size (HAES) orientation for sedentary overweight/obese women.DesignProject CHANGE was an 8-week randomized controlled trial with follow-up at 4-week.MethodTwenty-five sedentary, overweight women (BMI = 25–34.9) were randomized to either the SDT-based intervention with a HAES orientation (S/H) or exercise only (EX) intervention. The S/H group received exercise training and a weekly behavioral intervention while the EX group received only traditional supervised exercise training. Information about acceptability and feasibility was collected from process evaluation (i.e., participants' satisfaction and feedback) and objective data (e.g., retention, attendance, adherence to the PA goal). Assessments of PA participation and physical/psychological variables were obtained at baseline, post-intervention, and 4-week follow-up.ResultsParticipants reported high levels of satisfaction. Participation in the S/H group averaged 95%. Retention was high for both groups (S/H = 83.3% vs. EX = 84.6%), while adherence to the PA goal was better for the S/H group at follow-up (S/H = 60% vs. EX = 36.4%). The S/H intervention also resulted in larger effect sizes for changes in key motivational variables, including self-determination, autonomy, as well as goal-setting, planning and scheduling self-efficacy.ConclusionThe 8-week SDT-based intervention promoting Healthy at Every Size is feasible and acceptable and may result in better exercise adherence and improvements in motivational variables relative to traditional supervised exercise. These results support conducting additional research to determine the efficacy of this approach for promoting PA in sedentary, overweight women.
