Objective aerobic fitness level and neuropsychological functioning in healthy adolescents and emerging adults: Unique sex effects

ObjectiveResearch suggests positive relationships between aerobic fitness and cognition in older adults; however, limited research has adequately investigated the relationship between objectively measured aerobic fitness and broad cognitive functioning in healthy adolescents and young adults without psychiatric or physical health disorders. Further, studies to date have disproportionately examined males and failed to examine sex differences. Here we examine the relationship between aerobic fitness and neuropsychological functioning in physically healthy youth and whether sex moderates these findings.DesignSixty-four healthy emerging adults (16-25 years-old; 32 female) underwent measurement of objective aerobic fitness (VO₂ max) and neuropsychological assessment. Exclusion criteria included: left-handedness, prenatal medical issues or alcohol/illicit drug exposure, Axis-I psychiatric disorders, major medical disorders including metabolic conditions such as diabetes, hypertension, hyperlipidemia, major neurologic disorders, LOS greater than 2 min, intellectual disability or learning disability, regular substance use (e.g., greater than bi-weekly use of cannabis) or positive drug toxicology testing.MethodMultiple regressions examined VO₂ max, sex, sex*VO₂interaction in relation to neurocognition, controlling for objectively measured body fat percentage.ResultsPrior to including body fat percentage, higher VO₂ max related to improved working memory (Letter-Number Sequencing; p = .03) and selective attention (CPT-II hit response time standard error; p = .03). Aerobic fitness significantly interacted with sex, as higher-fit males had better performance on two sustained attention tasks while females did not demonstrate this pattern (CPT-II variability standard error, p = .047; Ruff 2&7 Total Speed, p = .02). Body fat percentage was positively slower cognitive flexibility (D-KEFS color-word switching/inhibition, p = .046).ConclusionsVO₂ independently predicted better working memory and selective attention. Increased aerobic fitness level related to increased performance on sustained attention tasks in males but not females. Therefore, aerobic fitness may be positively related to better cognitive functioning in physically healthy adolescents and emerging adults without metabolic conditions. Further research into factors (e.g., intensity or type of activity) that may relate to beneficial outcomes by sex are needed.     

Living well: Empirically developed structural equation model for healthy and effective self-regulation

The purpose of this study is to develop and empirically test a structural equation model (SEM) for healthy and effective self-regulation based on the propositions of self-determination theory (SDT). A cross-sectional data sample (N = 6,705) is used to test the model. The results of the SEM demonstrate good to excellent global fit indices (RMSEA = 0.06, SRMR = 0.04 CFI = 0.97, TLI/NNFI = 0.95) and excellent local fit indices (p < 0.001). It is acknowledged that longitudinal and experimental research designs will be necessary to infer causal effects. However, based on the strong theoretical and empirical grounding of the model, indications for causal effects are discussed beyond correlational relations. The local fit indices imply that autonomy of goals, intrinsic values orientation, mindfulness, and the newly integrated construct clarity about personal values positively affect psychological needs satisfaction and facets of subjective and psychological well-being. Additionally, they indicate that mindfulness and clarity about personal values have the greatest benefits on individual health, well-being, and effectiveness. These results are crucial as they emphasize the significant role of mindfulness in healthy and effective self-regulation. Furthermore, they put the spotlight on a rather new construct; clarity about personal values. By having transferred the knowledge base of SDT into an empirically derived model of healthy and effective self-regulation, this study provides well-grounded indications of how health, well-being, and effectiveness in individuals may be fostered. These indications offer new insights for theory building and practical interventions in domains like psychotherapy, healthcare, organizations, sports, and education.     

Poorer aerobic fitness relates to reduced integrity of multiple memory systems

Epidemiological investigations have revealed increases in the prevalence of sedentary behaviors in industrialized societies. However, the implications of those lifestyle choices and related cardiorespiratory fitness levels for memory function are not well-understood. To determine the extent to which cardiorespiratory fitness relates to the integrity of multiple memory systems, a cross-sectional sample of young adults were tested over the course of 3 days in areas related to implicit memory, working memory, long-term memory, and aerobic fitness. Findings revealed an association between aerobic fitness and memory function such that individuals with lower cardiorespiratory fitness exhibited poorer implicit memory performance and poorer long-term memory retention. These data indicate that cardiorespiratory fitness may be important for the optimal function of neural networks underlying these memory systems.     

Observed staff engagement predicts postive relationships and well-being in a physical activity-based program for low-income youth

Positive youth development (PYD) programs aim to support long-term well-being in young people by building their strengths and assets. PYD program staff are pivotal in achieving this goal, as positive staff-youth interactions are associated with well-being in youth. Much of this research relies on youth perceptions of interactions with staff. A better understanding of how observed staff behaviors are associated with youth outcomes would provide guidance for developing interventions regarding effective staff behaviors. This study examined associations between observed staff behaviors and youths' perceptions of their relationships with staff and well-being. Participants were recruited from a summer physical activity-based PYD program for underserved youth. Staff (N = 24, 16 women, 8 men) were observed by researchers to evaluate their engagement, interaction, safety, and support behaviors. Youth from diverse backgrounds (N = 394; 47% girls, 53% boys; M_age = 10.20; 44% Latino/a) completed measures of their perceptions of relationships with staff (mutual respect, autonomy support, and care), and well-being (hope, self-esteem, and social competence) at the end of the program. Structural equation modeling indicated that observed staff engagement positively predicted youth perceptions of their relationships with staff and well-being. Youth perceptions of positive social relationships with staff also positively predicted their well-being. Staff who create opportunities for youth to reflect and respond to program activities are perceived as valuing, making genuine connections, and considering the opinions and feelings of youth. Developing ways to enable staff to build relationships with youth that include these features is an important avenue for future research.     

Benefits of regular aerobic exercise for executive functioning in healthy populations

Research suggests that regular aerobic exercise has the potential to improve executive functioning, even in healthy populations. The purpose of this review is to elucidate which components of executive functioning benefit from such exercise in healthy populations. In light of the developmental time course of executive functions, we consider separately children, young adults, and older adults. Data to date from studies of aging provide strong evidence of exercise-linked benefits related to task switching, selective attention, inhibition of prepotent responses, and working memory capacity; furthermore, cross-sectional fitness data suggest that working memory updating could potentially benefit as well. In young adults, working memory updating is the main executive function shown to benefit from regular exercise, but cross-sectional data further suggest that task-switching and posterror performance may also benefit. In children, working memory capacity has been shown to benefit, and cross-sectional data suggest potential benefits for selective attention and inhibitory control. Although more research investigating exercise-related benefits for specific components of executive functioning is clearly needed in young adults and children, when considered across the age groups, ample evidence indicates that regular engagement in aerobic exercise can provide a simple means for healthy people to optimize a range of executive functions.     

Self-regulation and tailgating behaviours among young drivers

Young drivers aged 17 to 25 years are overrepresented in road crash fatalities globally. In Queensland, Australia, tailgating is an illegal behaviour that has been attributed to at least 8,000 rear-end crashes per year. Notably, it has been found that young drivers tailgate more frequently than older drivers. This study utilised self-determination theory to understand self-regulation behind tailgating among young drivers. This theory has yet to be applied to understand tailgating but has been successful in understanding other risky driving behaviours, suggesting self-determination theory may have predictive utility in explaining tailgating. Participants (n = 609) aged 17 to 25 years (M_age = 20.61 years) completed an anonymous online survey measuring engagement in tailgating, external and internal regulation, trait self-regulation, and aggressive driving. Results indicated that young drivers less influenced by legal and non-legal sanctions are likely to engage in tailgating more frequently (lower external regulation). Young drivers influenced by safe driving values were less likely to engage in tailgating (greater internal regulation). Poorer trait self-regulation and higher measures of aggressive driving were predictors of more frequent tailgating in young drivers. The results support the development of informative campaigns centred on the self-determination theory with the aim of educating young drivers on the implications of tailgating and safe following distances.     

The effects of aerobic- versus strength-training on body image among young women with pre-existing body image concerns

This experiment compared the effects of aerobic-training (AT) versus strength-training (ST) on body image among young women with pre-existing body image concerns. Theory-based correlates of body image change were also examined. Participants were 46 women (M age = 21.5 years), randomly assigned to an 8-week AT or ST intervention consisting of supervised exercise 3 days/week. Multidimensional measures of body image were administered pre- and post-intervention, along with measures of physical fitness, perceived fitness, and exercise self-efficacy. Women in the AT condition reported greater reductions in social physique anxiety (p = .001) and tended to report greater improvements in appearance evaluation (p = .06) than women in the ST condition. Changes in perceived fatness, perceived aerobic endurance and aerobic self-efficacy were significantly correlated with body image change (ps < .003). Results provide direction for prescribing exercise to improve body image and advancing theory to account for the effects of exercise.     

Using video docuseries to explore male professional football head coaches’ well-being experiences throughout a season

Football coaches have disclosed how their work environment is unpredictable and demanding, comprising a multitude of stressors which can impede well-being. Additionally, the masculine culture within football often promotes suppression of voice, causing internalisation of thoughts and isolation. Due to professional football head coaches being a seldom-heard group, little is known about how they experience well-being within their given context (i.e., ecological niche). The present study utilised football docuseries and a bioecological framework to explore how four male professional head coaches experienced well-being whilst working in one of the top European football leagues (Premier League, La Liga). Four docuseries were sampled and resulted in the analysis of 31 episodes (M^duration = 46.6 min, SD = 4.5 min). The study implemented an adapted interpretative phenomenological analysis approach to illuminate convergences and divergences in contextual accounts. These accounts resulted in five group experiential themes: ‘I belong to the game’; ‘he belongs to the game’; ‘you need the right people around you’; ‘it’s difficult to describe the manager without describing the person’; and ‘people are trying to stab you’. The findings indicate that football coaches may experience identity conflicts and become deeply absorbed in their work. This impacts not only their well-being but also their family’s, who they often turn to for social support. Consequently, by unveiling nuanced challenges to coaches’ well-being, organisations may be better informed to offer more aligned and bespoke well-being support systems.

Protective effect of aerobic fitness on the detrimental influence of exhaustive exercise on information processing capacity

Although aerobic fitness has been thought to protect against the detrimental cognitive effects following exhaustive exercise, available evidence from studies using traditional mean behavioral measures remain somewhat equivocal.PurposeThis study aimed to reconcile this discrepancy by using a novel theory-driven diagnostic tool, the Systems Factorial Technology (SFT).MethodsSixty-six healthy young adults aged from 18 to 30 years old with different levels of aerobic fitness (n = 33 for the higher-fit and lower-fit groups) completed a go/nogo version of redundant-target task before and after a graded exercise test (GXT) until exhaustion. SFT was used to calculate the resilience capacity, which reflects the information processing capacity underlying inhibitory control.ResultsFollowing the GXT, both higher-fit and lower-fit groups showed faster responses while leaving accuracy unchanged as compared to the performance at the pretest. On the other hand, the resilience capacity decreased for the lower-fit group but was maintained for the higher-fit group.ConclusionThe present findings suggest that aerobic fitness may modulate the individual difference in decisional mechanism following exhaustive exercise. In sum, this study offers an alternative mechanistic explanation regarding cognitive individual differences in response to exhaustive exercise and provides novel insights into the significance of maintaining a state of high physical fitness for those who need to perform cognitively challenging tasks under physically stressful conditions (e.g., elite athletes).     

The role of transport in supporting the autonomy of young adults

This study explored the relationship between transport independence and autonomy among young people. A sample of 543 participants aged between 17 and 25 years (M = 21.5, SD = 2.4) completed an online survey asking about well-being, psychological autonomy, transport independence and transport disadvantage. It was predicted that transport independence would be positively related to psychological autonomy and enhanced well-being, whereas transport disadvantage would be inversely related. The data were analysed using Structural Equation Modelling. Consistent with the study hypothesis, it was found that transport independence through car ownership and low levels of transport disadvantage were associated with high levels of psychological autonomy which was strongly correlated with well-being. This suggested that having the freedom and means to get around and visit friends, go to work or school and to participate in leisure activities may provide young people with a sense of autonomy and that this may lead to enhanced well-being.     

Prospective associations between physical fitness and executive function in adolescents: The UP&DOWN study

IntroductionThe objective of the present work is to investigate the prospective associations between physical fitness components (cardiorespiratory fitness, motor fitness, and muscular strength) and two domains of executive function (working memory and inhibitory control) in adolescents.MethodsA total of 422 Spanish adolescents (13.35 ± 1.54 years, at baseline) from the UP&DOWN study with assessments at baseline and at 2-year follow-up were included in the analysis. Physical fitness was assessed using the ALPHA Fitness Test Battery. Working memory was measured by the n-back task and inhibitory control by the go/no-go task. Relationships of physical fitness components with working memory and inhibitory control were examined using linear regression models, adjusted for confounders.ResultsHigher baseline levels of the three physical fitness components (cardiorespiratory fitness, motor fitness, and muscular strength) individually predicted better performance on the working memory (β_ranged, from .159 to .207; all p < .012) and inhibitory control (β_ranged, from 0.168 to 0.263; all p < .004) tasks at the 2-year follow-up. Muscular strength was the only component associated with inhibitory control independent of the other 2 physical fitness components (β = 0.266; p = .005).ConclusionsAll components of adolescents’ physical fitness at baseline were individually associated with better working memory and inhibitory control at 2-year follow-up. Specifically, our results revealed that muscular strength was the component showing the strongest association with executive function, and even the only fitness component associated with inhibitory control independent of the other fitness components. These findings may have important public health and educational implication, since promoting exercise programs that improve physical fitness, and particularly, muscular strength, may positively influence cognitive health.     

Music listening and emotional well-being in adolescence: A person- and variable-oriented study

The principal aim of this study was to determine if different profiles (types) of emotional reactions following music listening (happiness and sadness) characterized different levels of emotional well-being (i.e., positive and negative affects) in adolescence. The secondary aim was to examine relationships between social congruence in music tastes with friends or parents (i.e., sharing similar music tastes and having fewer conflicts about music) and emotional well-being in adolescence. This study's sample was composed of 316 adolescents (M = 15.32 and S.D. = 0.90 years of age; 172 girls and 144 boys). Cluster analysis identified three profiles: (1) ‘emotionally-negative listeners’ (medium happiness and higher sadness); (2) ‘emotionally-limited listeners’ (lower happiness and lower sadness); (3) ‘emotionally-positive listeners’ (higher happiness and lower sadness). Results indicated that ‘emotionally-negative listeners’ had less emotional well-being, that ‘emotionally-positive listeners’ had more emotional well-being, and that social congruence in music tastes with both friends and parents were related to more emotional well-being.     

The sexual dimorphic association of cardiorespiratory fitness to working memory in children

The present investigation examined the sexual dimorphic patterns of cardiorespiratory fitness to working memory in preadolescent children (age range: 7.7–10.9). Data were collected in three separate studies (Study 1: n = 97, 42 females; Study 2: n = 95, 45 females; Study 3: n = 84, 37 females). All participants completed a cardiorespiratory fitness assessment in addition to a specific measure of working memory (i.e. the operation span task, the n‐back task, or the Sternberg task). Results from all three samples revealed that higher cardiorespiratory fitness levels were associated with better working memory performance only for males with no such relation observed for females. In addition, the sexually dimorphic pattern was selective for the most challenging working memory conditions in each task. Together, these findings reveal new evidence that cardiorespiratory fitness is selectively related to better working memory performance for male children. This investigation provides additional insight into how interventions aimed at improving fitness may influence cognitive development differentially among preadolescent children.     

Emergent self-regulation skills among very young ethnic minority children: A confirmatory factor model

Emerging self-regulation skills were assessed in 407 low-income African American and Latino (primarily Mexican-origin) preschoolers. A battery of self-regulation tasks was administered when children were 2½ years old and again approximately 1 year later. Confirmatory factor analyses supported four components of self-regulation: inhibitory control, complex response inhibition, set shifting, and working memory. Complex response inhibition was too rare a skill in this sample to be detected reliably from measures collected at 2½ years of age, but it emerged from measures collected at 3½ years. In addition, significant ethnic differences were found in that African American children scored better on measures of complex response inhibition and set shifting, whereas Latino children scored better on measures of inhibitory control and working memory. Implications of study findings for measuring self-regulation in low-income ethnic diverse populations of young children, as well as for developing interventions to enhance self-regulation development, are discussed.     

Adolescents' social anxiety dynamics in a latent transition analysis and its psychosocial effects

Background/ObjectiveThe present study aims to explore the dynamics of social anxiety profiles in adolescents over time and the psychosocial effects these dynamics have.MethodA representative sample of Andalusian (southern Spain) adolescents in Secondary Education was drawn. The study used single-stage stratified cluster sampling. A total of 2,140 students aged 11-16 years (47% girls; M_ageT1 = 13.68, SD = 1.27) were involved at two time points with a six-month interval.ResultsThe results provided a four-profile structure: low social anxiety, moderate cognitive disturbance, high with difficulties in new situations, and high social anxiety. The latent transition analysis showed a stability in the social anxiety profiles of between 58%-61%. Those adolescents who remained in or transitioned to profiles with higher social anxiety scored worse on peer adjustment, peer victimization and subjective well-being.ConclusionsThe study may contribute the improvement of the psychological treatments in social anxiety and reduce adverse effects on peer relationships and well-being by distinguishing the profiles and their dynamics.     

Testing a holistic conceptual framework for early childhood teacher well-being

Using a holistic conceptualization of teacher well-being in concert with the Job Demands and Resources (JD-R) framework, our interdisciplinary study examined associations among various job demands and resources and whole teacher well-being (i.e., professional, psychological, and physical well-being) in early care and education settings. First, we investigated direct associations of job demands and resources with teachers' professional well-being. Second, we tested two models of potential mediation for the relationship of job demands and resources to well-being using structural equation modeling techniques: (a) that psychological and physical well-being mediate the relationship between demands, resources, and professional well-being; and (b) that professional well-being mediates the relationship between demands, resources, and psychological and physical well-being. Although our sample of early childhood teachers (n = 262) reported high levels of professional well-being (i.e., work commitment, self-efficacy), a substantial number of them experienced challenges in both psychological (e.g., perceived stress, depressive symptoms) and physical (e.g., ergonomic pain) well-being. As expected, teachers' work-related stressors and work resources (positive work climate, quality of the physical environment) were directly associated with teachers' professional well-being. Contrary to our expectations, however, instrumental resources (i.e, wages, health insurance) did not predict any aspects of teachers' professional well-being. Our data only supported the first of the two tested mediation hypotheses (i.e., that psychological and physical well-being mediated the associations between working conditions and professional well-being), but with one caveat: physical well-being preceded psychological well-being in mediating the associations. These results advance our understanding of the challenges present in the early childhood workforce and have implications for policies and programs to improve teacher working conditions and well-being.     

Reactivity to Exclusion Prospectively Predicts Social Anxiety Symptoms in Young Adults

Peer victimization leads to negative outcomes such as increased anxiety and depression. The prospective relationship between peer victimization and social anxiety in children and adolescents is well established, and adults with social anxiety disorder (SAD) are more likely than individuals with other anxiety disorders to report a history of teasing. However, a crucial bridge between these findings (peer victimization in young adults) is missing. We manipulated perceptions of peer exclusion in a young adult sample (N = 108) using the Cyberball Ostracism Task. Reactivity to exclusion prospectively predicted social anxiety symptoms at a 2-month follow-up, whereas self-reported teasing during high school and current relational victimization did not. This research suggests that reactions to peer victimization may be a worthwhile target for clinical interventions in young adults. Targeting how young adults react to stressful social interactions such as exclusion may help prevent the development of SAD. Future research should test if reactivity to exclusion plays a role in the relationship between other disorders (e.g., depression) and peer victimization.     

Memories of school recess predict physical activity enjoyment and social-emotional well-being in adults

School recess can provide social, emotional, and physical benefits for children. Yet, not all children experience recess the same, as inequity in access to recess and variability in the quality of recess exist. Researchers have yet to understand the long-term implications of recess experiences on adult well-being and physical activity behaviors. The purpose of this study was to explore the inter-relationships between memories of recess, physical activity, and social-emotional well-being. A total of 514 adults between the ages of 19 and 79 (M = 45.56; SD = 15.62) were surveyed via Prolific, a web-based research platform. Participants were asked about their memories of recess enjoyment and recess exclusion, and current physical activity levels, physical activity enjoyment, social isolation, social role satisfaction, and sense of meaning and purpose. Structural equation modeling analysis showed that memories of recess enjoyment were associated with meaning and purpose (β = 0.138, p < .05) and PA enjoyment (β = 0.183, p < .05). Furthermore, retrospective recess exclusion predicted current social isolation (β = 0.266, p < .05) and was negatively associated with retrospective recess enjoyment (β = −0.379, p < .05). Findings highlight the importance of childhood recess experiences and its impact on current physical activity behaviors, social isolation, and meaning and purpose later in life. Consistent with other research, early positive physical activity experiences, in the form of recess, appear to provide more assurances that one will engage in healthier lifestyle behaviors and more favorable psycho-socio-emotional profiles in adulthood.     

Remembering events related to close relationships,self-growth,and helping others: Intrinsic autobiographical memories,need satisfaction,and well-being

The present research examined the relationships between memories with intrinsic versus non-intrinsic themes, need satisfaction, and well-being. In Study 1, participants (n = 244) who included intrinsic themes when asked to describe an autobiographical memory reported greater well-being than participants who did not. The degree of need satisfaction characterizing these memories mediated the relationship between intrinsic memories and well-being. In Study 2, participants (n = 126) were assigned to describe a memory characterized by intrinsic (e.g., helping others) or extrinsic (e.g., popularity) values. Need satisfaction characterizing the intrinsic, but not extrinsic, memories, was associated with well-being. Describing an intrinsic (but not an extrinsic) memory positively increased situational well-being. Need satisfaction in the intrinsic memories predicted the subsequent increase in well-being.
