A diagnosis of gender dysphoria remains the primary requirement for transgender people to receive medical and legal gender affirmation services. Three focus groups conducted in 2018 with transgender and gender diverse (TGD) adolescents were assessed to understand how they define and use the term dysphoria and how the clinical discourse of gender dysphoria relates to their sense of self and overall wellness. The 21 participants (age 12–18) were primarily White (n = 19, 90%; Hispanic n = 2, 10%). Thirteen adolescents had a masculine identity, 2 feminine, and 6 genderqueer/nonbinary. TGD youth understood the clinical definition of gender dysphoria but expanded its use; reported stigma as the cause of some of their dysphoria; and used their conceptualization of dysphoria to find self-acceptance. This study highlights the perceived harm and potential limitations of using diagnostic language to define identity. However, through rescripting and self-definition, TGD youth exercise personal agency and reject stigma. [ABSTRACT FROM AUTHOR]

Children with pulmonary hypertension (PH) often demonstrate limited exercise capacity. Data support exercise as an effective nonpharmacologic intervention among adults with PH. However, data on exercise training in children and adolescents are limited, and characteristics of the optimal exercise program in pediatric PH have not been identified. Exercise programs may have multiple targets, including muscle deficits which are associated with exercise limitations in both adult and pediatric PH. Wearable accelerometer sensors measure physical activity volume and intensity in the naturalistic setting and can facilitate near continuous data transfer and bidirectional communication between patients and the study team when paired with informatics tools during exercise interventions. To address the knowledge gaps in exercise training in pediatric PH, we designed a prospective, single arm, nonrandomized pilot study to determine feasibility and preliminary estimates of efficacy of a 16‐week home exercise intervention, targeting lower extremity muscle mass and enriched by wearable mobile health technology. The exercIse Training in pulmONary hypertEnsion (iTONE) trial includes (1) semistructured exercise prescriptions tailored to the participant's baseline level of activity and access to resources; (2) interval goal setting fostering self‐efficacy; (3) real time monitoring of activity via wearable devices; (4) a digital platform enabling communication and feedback between participant and study team; (5) multiple avenues to assess participant safety. This pilot intervention will provide information on the digital infrastructure needed to conduct home‐based exercise interventions in PH and will generate important preliminary data on the effect of exercise interventions in youth with chronic cardiorespiratory conditions to power larger studies in the future.

OBJECTIVE: To explore 24-h postexercise glycemia and hypoglycemia risk, data from the Type 1 Diabetes Exercise Initiative Pediatric (T1DEXIP) study were analyzed to examine factors that may influence glycemia. RESEARCH DESIGN AND METHODS: This was a real-world observational study with participant self-reported physical activity, food intake, and insulin dosing (multiple daily injection users). Heart rate, continuous glucose data, and available pump data were collected. RESULTS: A total of 251 adolescents (42% females), with a mean ± SD age of 14 ± 2 years, and hemoglobin A1c (HbA1c) of 7.1 ± 1.3% (54 ± 14.2 mmol/mol), recorded 3,319 activities over ∼10 days. Trends for lower mean glucose after exercise were observed in those with shorter disease duration and lower HbA1c; no difference by insulin delivery modality was identified. Larger glucose drops during exercise were associated with lower postexercise mean glucose levels, immediately after activity (P < 0.001) and 12 to <16 h later (P = 0.02). Hypoglycemia occurred on 14% of nights following exercise versus 12% after sedentary days. On nights following exercise, more hypoglycemia occurred when average total activity was ≥60 min/day (17% vs. 8% of nights, P = 0.01) and on days with longer individual exercise sessions. Higher nocturnal hypoglycemia rates were also observed in those with longer disease duration, lower HbA1c, conventional pump use, and if time below range was ≥4% in the previous 24 h. CONCLUSIONS: In this large real-world pediatric exercise study, nocturnal hypoglycemia was higher on nights when average activity duration was higher. Characterizing both participant- and event-level factors that impact glucose in the postexercise recovery period may support development of new guidelines, decision support tools, and refine insulin delivery algorithms to better support exercise in youth with diabetes.

Geographies of youth have explored multiple modalities of youth political agency, yet privilege apolitical or progressive forms of politics. We propose expanding the scholarship to formal arenas where conservative and reactionary politics are practiced, as these form another significant domain within which youths exercise citizenship. The paper draws on two aspects of the 'lived citizenship' framework developed by Kirsi Kallio and colleagues?: a desire to rescale society to the strictures of nation-state sovereignty and imagined national heritage (spatial aspect), and provocations of despised 'globalists' (performative aspect). We analyze these through the former youth wing of Finland's populist-right party, Perussuomalaiset Nuoret (Finns Youth). [ABSTRACT FROM AUTHOR]

The physical and psychological load of small-sided games (SSGs) can affect players' neuromuscular and cognitive functions. Yet, little is known about the acute performance changes after such a specific exercise in young soccer players and their association with exercise load applied. This study investigates i) the neuromuscular and perceptual-cognitive response to the SSG exercise load, and ii) the relationship between pre- and post-SSG changes in variables of performance and the respective exercise load in youth soccer players. Sixteen participants (13.6 ± 0.5 years) underwent a 30-min SSG 4v4 + GK protocol. Prior to and after the SSG they performed countermovement jump (CMJ), planned and reactive Y-shaped agility tests (PA, RA), and go/no-go task (GNG). Their subjective perception of fatigue was evaluated by visual analog scale. Fatigue induced by SSG (perception of fatigue increased by 41.56%, p = .001, g = 4.15) increased PA time (4.04%, p = .002, g = .97), RA time (6.45%, p = .003, g = 1.16), and number of errors in the response inhibition task (87.1%, p = .023, rc = .57), whilst decreased CMJ height (-6.65%, p = .014, g = .56). These performance deteriorations were not significantly associated with neither internal nor external load variables. However, a less pronounced drop in performance was related to external load variables, i.e., ΔCMJ height and ΔRA time correlated with very high-speed running (rs = .66, p = .006; rs = -.50, p = .022; respectively) and maximal speed (r = .54, p = .032; r = -.52, p = .037; respectively), whilst ΔPA time was associated with high-intensity accelerations (rs = -.76, p = .002). These findings indicate that fatigue induced by SSG affects both planned and reactive agility, decision-making in response inhibition task, and explosive strength in youth soccer players regardless of significant contribution of any robust internal or external load variables. Nonetheless, high-intensity actions within SSG partially compensate for the decrements in their agility performance and explosive strength. The load variables encountered during SSG do not fully reflect youth players' neuromuscular and perceptual-cognitive responses to sport-specific exercise. [ABSTRACT FROM AUTHOR]

Social studies education research lauds the importance of schools as spaces to practice democratic values while also largely ignoring the agency youth exercise to shape their lives in the present. This article explores how young people organize and enact democratic practices within youth-mediated contexts in schools by examining the pedagogy of solidarity that adults must enact to support youths' visions of democratic life. This qualitative study examines youth organizers' response to the murder of a Black man in their community and how adults acted in solidarity or against their civic action. The findings elucidate how youth organizing and action can be re-framed as democratic actions and what it takes for adults to make this epistemic and ontological maneuver. The article concludes with a discussion about implications for social studies research when centering youth agency, as well as an analysis of social education beyond the classroom and adult-centered understandings of democratic education.

Youths' affinity for snack foods is well-documented; in various contexts, they sell chips, candy, and other goods. Adults may frame such sales as either entrepreneurial or deviant, which can contribute to positive youth development (on one hand) or cycles of disengagement and criminalization (on the other). Drawing on ethnographic and interview data from Hamilton High School, I show how adults' criminalization of snack sales led the activity to more closely resemble that which they feared: drug sales. Snack sales constitute one way in which youth exercise agency in the face of broad institutional control, leading some to challenge the legitimacy of the school overall. These findings represent a case of how youth experience "criminalized childhoods" in a school context. [ABSTRACT FROM AUTHOR]

BACKGROUND: In recent years, studies on chronic diseases related to aging have attracted wide attention worldwide. As the heart grows with age, premature aging may occur. Exercise is a safe and healthy intervention that can delay its aging. OBJECTIVE: To observe the effect of regular aerobic exercise on the aging of cardiomyocytes and explore its mechanism. METHODS: Healthy male SPF Sprague-Dawley rats aged 3 months (young, n=20), 13 months (middle age, n=24), and 22 months (old, n=24) were randomly divided into youth rest group, youth exercise group, middle age rest group, middle age exercise group, old age rest group, and old age exercise group. The three resting groups did not do aerobic exercise intervention, and the three exercise groups were given a 10-week incremental load aerobic treadmill exercise consisting of 6-week incremental load exercise and 4-week constant load exercise. RT-PCR and immunohistochemical detection were used to detect myocardial Beclin-1, CaMKIIα1, AMPKα1/pAMPKα1, and PI3K/Akt/mTOR pathway-related proteins and genes. RESULTS AND CONCLUSION: After regular aerobic exercises, compared with the three resting groups, the expression levels of Beclin-1 in cardiomyocytes were significantly down-regulated in the three exercise groups. The expression levels of myocardial CaMKIIα1 mRNA were also down-regulated in the three exercise groups. The protein expression levels of pAMPKα1 and AMPKα1 in the three resting groups showed an aging trend, and the expression levels of AMPKα1 in the young, middle age, and old age exercise groups were up-regulated by 16.50% (P < 0.05), 63.09% (P < 0.05), and 31.12% (P < 0.01), respectively. The expression levels of pAMPKα1 were also significantly up-regulated by 131.29% in the young exercise group (P < 0.01), 40.55% in the middle age exercise group (P < 0.01), and 16.77% in the old age exercise group (P < 0.05). Overall, the expression levels of PI3K in the myocardium were down-regulated in the three exercise groups compared with the three resting groups, while the expression levels of AKT1 mRNA were down-regulated in the young and middle age exercise groups. The expression level of mTOR mRNA was slightly down-regulated in the young exercise group, little changed in the middle age exercise group, and significantly upregulated in the old age exercise group. To conclude, aerobic exercise can significantly up-regulate the expression of PI3K, promote the activity of mTOR, downregulate the expression of CaMKIIα1, down-regulate the ratio of pAMPKα1/AMPKα1, decrease the expression of Beclin-1, regulate the level of myocardial autophagy, and make it tend to be normal and stable in aged rats, thereby delaying myocardial aging.

Graded exertion testing (GXT) is an important tool for concussion management, as it is used to personalize post-concussion exercise prescription and return athletes to sport. However, most GXT requires expensive equipment and in-person supervision. Our objective was to assess the safety and feasibility of the Montreal Virtual Exertion (MOVE) protocol, a no-equipment, virtually compatible GXT, in healthy children and children with subacute concussion. The MOVE protocol consists of seven stages of bodyweight and plyometric exercises performed for 60 sec each. Twenty healthy (i.e., non-concussed) children completed the MOVE protocol virtually over Zoom Enterprise. Next, 30 children with subacute concussion (median: 31.5 days post-injury) were randomized to the MOVE protocol or Buffalo Concussion Treadmill Test (BCTT), which increases the incline or speed of the treadmill every minute until maximum exertion. Out of an abundance of caution, all concussed participants completed the MOVE protocol in an in-person clinical space. However, the test evaluator was stationed in a different room within the clinic and administered the MOVE protocol using Zoom Enterprise software to mimic telehealth conditions. Safety and feasibility outcomes were recorded throughout GXT, including heart rate, rate of perceived exertion (RPE), and symptom outcomes. No adverse events were recorded, and all feasibility criteria were successfully met in healthy youth and youth with concussion. Among concussed youth, increases in heart rate (MOVE: 82.4 ± 17.9 bpm, BCTT: 72.1 ± 23.0 bpm; t(28) = 1.36, p = 0.18), RPE (MOVE: 5.87 ± 1.92, BCTT: 5.07 ± 2.34, t(28) = 1.02, p = 0.32), and overall symptom presentation were similar between the MOVE and BCTT protocols. The MOVE protocol is a safe and feasible GXT in healthy youth and youth with subacute concussion. Future studies should assess the fully virtual administration of the MOVE in children with concussion, MOVE protocol tolerability in children with acute concussion, and whether the MOVE protocol can be used to guide individualized exercise prescription.

One uniquely marginalizing school environment for sexual and gender diverse (SGD) youth is school based sex education (SBSE). While research has documented the negative sexual and mental health impacts these marginalizing environments can have for SGD youth, we know less about the developmental competencies that this population of youth exercises to survive in and cope with these environments. In this paper, we aim to answer the following question: What are the developmental competencies that SGD youth exercise in sex education spaces? We conducted focus groups with SGD youth (n = 17) in a Midwestern metropolitan region. Our study documents youth exercising six adaptive competencies to persevere through oppressive SBSE. Our data holds several scholarly and practical implications. In our discussion section, we present recommendations for creating inclusive and affirming school environments and nurturing these competencies in youth. Practitioner points: Sexual and gender diverse (SGD) youth endure oppression and marginalization in school‐based sex education (SBSE).SGD youth exercise adaptive competencies (knowledges and/or skills) to navigate through SBSE.Practitioners who work with youth are in unique positions to nurture these adaptive competencies in SGD youth, and to advocate for more equitable educational environments.

The exercise of youth citizenship in Colombia implies the participation of young people in public decision making. This article builds upon the frameworks of the Youth Citizenship Statute and the Public Policy of Digital Government and presents the process and results of a pilot program on the formation of legal, political and ethical competencies of young people in Marinilla, Antioquia. The program aimed to, aid youth citizenship in real and virtual spaces in the context of the Covid-19 pandemic. A multi-methodological model of digital research-action was implemented including Logical Framework Methodology (LFM), Technologies for Empowerment and Participation (TEP), and Digital Action and Local Political Advocacy (Adiplo). Twenty young people participated in the virtual course. As a result, the course qualified and contributed to the formation of the candidacy and election of five of the participants as municipal youth councilors of Marinilla. In addition, the participants provided their evaluation of public youth policy. [ABSTRACT FROM AUTHOR]

Geographic racism gives rise to health inequities that impact communities in detrimental ways. Southern ethnic minority groups, particularly African American/Black semi‐rural communities, are subject to especially unjust outcomes in health, education, and wealth. Asset‐based community development (ABCD) is a way of engaging with communities in participatory and positive ways that center community voices as expert. Youth can participate in ABCD, are sensitive to the ways in which their communities are structured, and have insights as to how to improve the places they live. We undertook a qualitative interview study which included a cognitive mapping exercise with 28 youth to understand how African American/Black youth who had participated in an ABCD‐informed summer program conceptualized community and preferences about where they lived. Using a phenomenological approach to qualitative analysis, our study revealed that many youth defined community as a combination of people and place, enjoyed engaging with unique resources in their communities as well as seeking peace and quiet, experienced hardships as "something everybody knows" when observing constraints on their communities, and were committed to their communities and interested in seeing—and participating in—their flourishing. Our study provides a nuanced and contemporary understanding of the ways in which African American/Black semi‐rural youth experience community which can contribute to cyclical asset‐based development strategy aimed at empowering young people and improving health outcomes in resilient communities.

This article discusses the impact of habitual exercise on cerebrovascular health in children and adolescents. The authors conducted a study to investigate cerebral blood flow (CBF) and cerebrovascular reactivity to carbon dioxide in youth, taking into account different stages of maturation. The study found that endurance-trained youth had higher global CBF at rest compared to untrained counterparts, and cardiorespiratory fitness was associated with global CBF in mature adolescents. The findings suggest that exercise training in adolescents may be necessary to counteract the negative consequences of higher sedentary time on cerebral haemodynamics. The study provides important insights into the role of exercise in promoting cerebrovascular health in youth. [Extracted from the article]

Sleep–wake stability is imbalanced with natural aging, and microRNAs (miRNAs) play important roles in cell proliferation, apoptosis, and aging; however, the biological functions of miRNAs in regulating aging-related sleep–wake behavior remain unexplored. This study varied the expression pattern of dmiR-283 in Drosophila and the result showed that the aging decline in sleep–wake behavior was caused by the accumulation of brain dmiR-283 expression, whereas the core clock genes cwo and Notch signaling pathway might be suppressed, which regulate the aging process. In addition, to identify exercise intervention programs of Drosophila that promote healthy aging, mir-283SP/+ and Pdf > mir-283SP flies were driven to perform endurance exercise for a duration of 3 weeks starting at 10 and 30 days, respectively. The results showed that exercise starting in youth leads to an enhanced amplitude of sleep–wake rhythms, stable periods, increased activity frequency upon awakening, and the suppression of aging brain dmiR-283 expression in mir-283SP/+ middle-aged flies. Conversely, exercise performed when the brain dmiR-283 reached a certain accumulation level showed ineffective or negative effects. In conclusion, the accumulation of dmiR-283 expression in the brain induced an age-dependent decline in sleep–wake behavior. Endurance exercise commencing in youth counteracts the increase in dmiR-283 in the aging brain, which ameliorates the deterioration of sleep–wake behavior during aging. [ABSTRACT FROM AUTHOR]

Exercise training can induce adaptive changes to tendon tissue both structurally and mechanically; however, the underlying compositional changes that contribute to these alterations remain uncertain in humans, particularly in the context of the ageing tendon. The aims of the present study were to determine the molecular changes with ageing in patellar tendons in humans, as well as the responses to exercise and exercise type (eccentric (ECC) and concentric (CON)) in young and old patellar tendon. Healthy younger males (age 23.5 ± 6.1 years; n = 27) and older males (age 68.5 ± 1.9 years; n = 27) undertook 8 weeks of CON or ECC training (3 times per week; at 60% of 1 repetition maximum (1RM)) or no training. Subjects consumed D2O throughout the protocol and tendon biopsies were collected after 4 and 8 weeks for measurement of fractional synthetic rates (FSR) of tendon protein synthesis and gene expression. There were increases in tendon protein synthesis following 4 weeks of CON and ECC training (P < 0.01; main effect by ANOVA), with no differences observed between young and old males, or training type. At the transcriptional level however, ECC in young adults generally induced greater responses of collagen and extracellular matrix-related genes than CON, while older individuals had reduced gene expression responses to training. Different training types did not appear to induce differential tendon responses in terms of protein synthesis, and while tendons from older adults exhibited different transcriptional responses to younger individuals, protein turnover changes with training were similar for both age groups.

This study aims at exploring the impact of a biometric program to develop certain physical and motor abilities for the group of youths in football. The sample of the research consists of (20) players of youth groups of Afak Club that has participated in the Iraqi first League season. The training method has been used after dividing the sample into two groups: experimental and control, (10) player for each one as well as for the pretest and the post-test. The period of the training method lasts for (8) weeks, (3) units per a week. (L) is used for cross=linked samples to be acquainted with the difference between pre/post measurement of tests under study, as well as in accordance with each one of these groups; (L) test is used for independent samples in favor of finding differences among the individuals of the two groups (the experimental and control) for pre-measurement. It is shown that there are significant differences at the level of significance (0.05) between pretest and posttest for the impact of the program under study for the experimental group to develop some physical and motor abilities. There are also some significant differences at the level of significance (0.05) for post-measurement between experimental and control groups for the same purpose concerning the sample of the research and in the interest of the experimental group. It is highly recommended by the researchers that the biometric program as a means of promoting and improving physical and motor abilities for the group of youths in football. [ABSTRACT FROM AUTHOR]

Although well‐evidenced in older adults, the effects of exercise on the hippocampus in youth are relatively unknown. This study examined the impact of a 6‐month school‐based physical activity intervention on hippocampal metabolism in adolescents using magnetic resonance spectroscopy. A subset of lower fit older adolescents [N = 56, 61% female, 16.1 ± 0.4 years] was included from four secondary schools (10 classes) in New South Wales, Australia, who were participating in a larger cluster randomized controlled trial. Participants were randomized to the Burn 2 Learn (B2L) intervention (five classes, 30 participants) or a control group (five classes, 26 participants). Changes in hippocampal metabolism were assessed using linear mixed models adjusted for clustering at the class level. We observed group‐by‐time effects for the B2L intervention on N‐acetylaspartate (NAA) (+2.66 mmol/L, 95% CI 0.20 to 5.11, d = 0.66) and glutamate+glutamine (Glx) (+3.38 mmol/L, 95% CI 0.34 to 6.42, d = 0.67) in the left hippocampus. Increases in left hippocampal NAA and Glx concentrations were associated with improvements in cardiorespiratory fitness (NAA: rs = 0.52, p =.016; Glx: rs = 0.57, p =.007), lower body muscular fitness (NAA: rs = 0.49, p =.018; Glx: rs = 0.59, p =.003), and working memory (NAA: rs = 0.42, p =.032; Glx: rs = 0.43, p =.028) in the intervention group. Our findings suggest physical activity may improve hippocampal metabolism in lower fit older adolescents with implications for working memory. Further studies involving larger samples are needed to replicate our findings. Participation in physical activity has small positive effects on measures of brain and cognition in youth, but the mechanisms are not well understood. This is the first study to examine the effects of an exercise intervention on adolescents' hippocampal metabolism using magnetic resonance spectroscopy and provides evidence for potential mechanisms linking participation in physical activity with enhanced executive function.

Youth organizing can generate tangible improvements in community conditions and institutions while simultaneously promoting positive development among participants and contributing to broader movements for social change. Yet, organizing initiatives must navigate an array of challenges as they seek to continuously engage new leaders to build on the accomplishments of their predecessors who are aging out of youth organizing. This study examines the leadership development ecosystem enabling an exemplary youth organizing initiative to persist, expand, and enhance its impact over 15 years. Analyses of interviews with 19 adolescent and young adult participants reveal that engagement often begins before high school and continues long afterward, with more established older leaders playing a variety of roles to engage younger participants and support their development as leaders. Findings suggest practical strategies that can enhance the sustainability of these initiatives, which are key to the development and exercise of youth power for social justice.

As a key part of promoting the physical health of the people and promoting social progress, sports has ushered in comprehensive vitality. More and more people's attention has been paid to the physical health status, especially the physical status of young people. In the field of physical fitness monitoring, although the state has continuously increased investment in human and financial resources, it still cannot meet the needs of the market. This study mainly discusses the monitoring of youth sports physique by intelligent medical robots based on cognitive computing. This study introduces the development and implementation process of the management system and the test planning of the system. It focuses on the realization of the scalable architecture of the system server application and the communication mechanism of the intelligent terminal application. With the development of collaborative computing, social computing, and the ever-changing demands of human-computer interaction, it is difficult for a single user to take into account the interactive tasks in complex scenarios. The collaborative interaction of multiusers has gradually been paid more and more attention. Teenagers can log in to the intelligent medical robot system or mobile phone terminal to make health test appointments, score inquiries, and prescription inquiries. Its display module displays different contents according to different login identities. For teenagers, it is necessary to check personal physical test results and have a position on their physical health. Through the intelligent medical robot system, the administrator records and analyzes the results of the youth health test and gives appropriate exercise prescriptions for the youth. This not only analyzes the functional requirements that meet the basic user needs, but also analyzes the nonfunctional requirements that meet the most basic security, stability, and robustness of the software. Intelligent medical systems can effectively help people learn medical knowledge better in today's postepidemic era. It also helps people to conduct self-diagnosis and self-examination of minor diseases to a certain extent, so as to improve their own health. From the functional requirements, each module of the intelligent medical robot system is functionally described. From a nonfunctional point of view, the design and implementation meet the performance requirements of client-side robustness, maintainability, and stability. Finally, the system architecture of the intelligent medical robot is designed, and the specific database table is given. During the research, 20% of the students believed that their physical condition had been improved through physical health monitoring. The state of national physique can reflect a part of the country's comprehensive national strength to a certain extent. Throughout history, the overall development trend of a society and a country is constrained by the two factors of the group's constitution and economic development. This research will contribute to the physical and mental development of adolescents. The robot designed in this paper meets the requirements of a large number of students' centralized testing and is more accurate, faster, and more convenient. [ABSTRACT FROM AUTHOR]

In order to solve the relationship between youth aerobic exercise and obesity reduction, an improved ant colony algorithm-oriented aerobic exercise method was proposed. Firstly, the changes in body shape, weight, BMI, body fat, body circumference, and other indicators of obese adolescents before and after aerobic exercise were used as the initial pheromone distribution matrix, and the random evolution factor and evolutionary drift threshold were introduced to establish the target function of reducing obesity caused by aerobic exercise in adolescents. The constraint conditions of the relationship between aerobic exercise and adolescent obesity reduction were explained, and the particle algorithm was introduced to establish the optimal model of aerobic exercise for adolescent obesity reduction. The experimental results show that with the increasing number of experiments, the advantages of this method are more obvious. From the overall level, the average modeling error of this method is about 0.053%, while the average error of the traditional method is about 0.186%, which shows that this method can control the error within a reasonable range, and it is proved that the improved ant colony algorithm can have a good correlation with the method of aerobic exercise.

This work aims to highlight the importance of the time dimension in the participation of young people in society, in order to take this element into greater consideration in the current socio-educational scenario. The work reveals how the participation exercised by youth in sociopolitical issues is, in part, mediated by the temporal dimension. This work arises from the study carried out within the CITADEL interuniversity collaborative research project "Smart Citizens for participatory cities" Ref.SMART01 / 2017-18 and its continuation in 2019/20 included in the call of the Iberoamerican Universities Union in which 4 countries of the 5 universities belonging to the IUU have participated (UNAM-National Autonomous University of Mexico, UBA-University of Buenos Aires, USP-University of São Paulo, UB-University of Barcelona and UCM-Complutense University of Madrid). This project focuses on the study of the gap between the civic experience of young people in formal education and their life in the citizen environment. For this, it is supported by research carried out by the teams of the aforementioned universities, through field work based on the focus group to obtain data from the different contexts to which the five participating institutions belong. The study, among other aspects on which part of the works published by the five universities has already been based, highlights the relevance of the temporal dimension in the participation of Iberoamerican youth in the sociopolitical sphere, as it is developed in this paper.

• IHE appeared to limit the drop in glycemia compared to CME during exercise. • No symptomatic hypoglycemic episode occurred during CME and IHE. • CME transiently reduced level 2 hyperglycemia compared with inactive days. From an early age, exercise is key to managing type 1 diabetes (T1D). However, hypoglycemia around aerobic exercise is a major barrier to physical activity in children. We explore whether intermittent high-intensity aerobic exercise (IHE), designed to mimic spontaneous childhood physical activity patterns, offers better protection against glycemic drop than continuous moderate-intensity exercise (CME). Five boys and 7 girls with T1D (9.8 ± 1.4y) performed ergo cycle-based randomized CME and IHE of identical duration and total mechanical load [50 %PWC 170 vs. 15sec(150 %PWC 170)/30 sec passive recovery; both during two 10-min sets, 5 min in-between]. Capillary glycemia during exercise and interstitial glucose during recovery were compared between exercises and an inactive condition, controlling for baseline glycemia, carbohydrate and insulin. The exercise-induced decrease in capillary glycemia was attenuated by 1.47 mmol·L−1 for IHE vs. CME (P < 0.05). No symptomatic hypoglycemic episodes occurred during exercises. Post-exercise time in hypoglycemia did not differ between conditions. During early recovery, CME reduced time spent > 16.7 mmol·L−1 compared with inactive days (P < 0.05; CME: 0 %; IHE: 16,7 %; INACTIVE: 41,7 %). IHE appeared to limit the glycemic drop compared to CME. Performing 20-min CME or IHE was not associated with increased hypoglycemic risk compared to being inactive. CME appeared even transiently protective against serious hyperglycemia.

Despite the multiple potential benefits, individuals with bipolar disorder (BD) report lower levels of moderate-vigorous exercise. We examined the correlates of exercise preference and tolerance among youth with BD, to inform future exercise intervention studies. In this cross-sectional study 107 adolescents (n = 54 BD, n = 53 healthy controls [HC]) completed the self-reported Preference for and Tolerance of the Intensity of Exercise Questionnaire, a 20-minute bout of moderate intensity aerobic exercise, and the Borg Rating of Perceived Exertion. Cardiorespiratory fitness (CRF) was calculated using a proxy measure. Variables associated with either exercise preference or tolerance at p < 0.01 in univariate analyses were entered into multivariable models. Significance was set at p < 0.05 for all analyses. Exercise tolerance and CRF were significantly lower in the BD group. There was no significant difference in exercise preference. Lower exercise preference among youth with BD was significantly associated with lower CRF (β = 0.39, p = 0.006) and higher perceived exertion (β = −0.33, p = 0.01), while higher exercise preference was associated with lifetime psychiatric hospitalization (β = 0.29, p = 0.04). Female sex (β = 0.31, p = 0.03), higher perceived exertion (β = −0.37, p = 0.007), and non-Caucasian race (β = 0.31, p = 0.02) were significantly associated with lower exercise tolerance in youth with BD. The current study adds to the limited literature examining exercise preference and tolerance in youth with BD and provides an avenue to examine these correlates further in clinical and exercise interventions. • We examined exercise preference and tolerance among youth with bipolar disorder. • Significantly lower exercise tolerance compared to controls. • Low exercise preference associated with lower fitness and higher perceived exertion. • Low exercise tolerance correlated with female sex, exertion and non-Caucasian race.

Psychological victimization is at least as strongly related as is physical victimization to depression, posttraumatic stress disorder (PTSD), and alcohol use as is physical victimization. The study's results underscored the relationships between eating disorders and IPV, and suggest that we should be examining loneliness and social withdrawal as potentially important causative factors in IPV. A relationship between EDs and IPV Fear of loneliness and social withdrawal significantly correlated with all test variables. [Extracted from the article]

Exercise is recommended for cardiometabolic benefits and to preserve or improve bone health, especially for older adults at increased risk of fracture. However, exercise interventions have modest benefits on areal bone mineral density (aBMD), and exercise can lead to bone loss in young athletes under certain conditions. In this narrative review, we discuss evidence for a disruption in calcium homeostasis during exercise that may diminish the skeletal benefits of exercise. Topics include 1) a general overview of the effects of exercise on aBMD; 2) discussion of the exercise-induced disruption in calcium homeostasis; 3) factors that influence the magnitude of the exercise-induced disruption in calcium homeostasis, including age, sex, and exercise mode, intensity, and duration; 4) oral calcium supplementation to minimize the exercise-induced disruption in calcium homeostasis; and 5) potential for exercise-induced increase in parathyroid hormone to be both catabolic and anabolic to bone. • Exercise can increase bone mass and prevent falls. • There is an acute catabolic response of bone metabolism to exercise. • Not yet known if exercise-induced increase in PTH is anabolic.

Pediatric disability prevalence has increased to 17.8% in recent years. This youth population faces a range of individual, social, and environmental level barriers to a healthy lifestyle. This is particularly concerning because this population is at a higher risk of obesity and lifestyle-related morbidity and mortality. Therefore, A-ONE: An Accessible and Online Nutrition & Exercise Program was designed to provide a comprehensive and holistic online program for youth with physical disabilities. A-ONE will offer two individualized fitness workouts and one accessible cooking session per week for 16-weeks. In addition, A-ONE will offer one social-mentoring session per week. All programming (4 sessions per week) will occur during after-school hours. The program will be offered 6 times during the 2-year grant period, enrolling 10 youth per cohort, for a total of 60 youth with physical disabilities. Outcomes to be examined include physical activity, fruit and vegetable consumption, independent meal preparation, quality of life, and self-efficacy. They will be assessed pre, post, and 4-weeks following the end of the program. Program fidelity and feasibility will also be assessed. While children with physical disabilities benefit from opportunities to engage in physical activity and nutrition, accessible programming is unavailable. Despite decades of disability rights legislation mandating access to equal education, there is still a lack of system level solutions to improve the health inequity for youth experiencing disabilities. This program represents a sustainable and scalable way to remove barriers and improve the trajectories of health among youth with a physical disability. [ABSTRACT FROM AUTHOR]
