Purpose: The International Study of Movement Behaviors in the Early Years (SUNRISE) was conducted in Tunisia to assess the proportion of preschoolers who met the World Health Organization guidelines for physical activity, sedentary behavior, and sleep. The study also evaluated the feasibility of the methods for the SUNRISE study.
Methods: Five kindergartens were recruited from urban and rural areas in Tunisia. Physical activity and sleep duration were assessed using a waist-worn ActiGraph. Screen time and sleep quality were assessed via an interview-administered parent questionnaire. The NIH Toolbox was used.
Results: A total of 112 preschoolers were assessed (50 boys, age = 4.1 [0.58]). Only 18% of children met all recommendations of the World Health Organization guidelines, while 53% met the sedentary screen time (in minutes per day), and 41% met physical activity recommendation (in minutes per day). Eighty-one percent of children met the sleep duration recommendation (in minutes per day). There was good compliance with the ActiGraph protocol.
Conclusions: This pilot study provided important insights into the feasibility of the study and the movement behaviors of Tunisian preschool children. The results suggest there is a need to promote healthy levels of physical activity and sedentary screen time in children, which should be a priority in public health initiatives, including preschool curricula, in Tunisia.

The Danish Christmas Seal Homes offer a 10-week residential stay for socially vulnerable children. We aimed to examine the effects on body composition and cardiometabolic fitness variables of the standard program (SG) and whether substituting physical activity sessions with sessions from a football-based health education program is beneficial for the participants ("11 for Health"; SG+). Three hundred and nine children participated in SG (12.4 [1.6] y) and 305 in SG+ (12.4 [1.4] y). Fat percentage was lowered by 6% for females (from 37% to 31%) and 8% for males (from 36% to 28%), with no between-group differences. We observed improvements in systolic and diastolic blood pressure (3 and 5 mm Hg, respectively), resting heart rate (10 beats/min), aerobic fitness, jump performance, and relative muscle mass with no between-group differences. Furthermore, there were between-group differences in insulin levels for females (1.7 pmol/L; 95% CI, 0.3 to 3.0) and postural balance for males (1.0 s; 95% CI, 0.0 to 2.0), both in favor of SG+, and covered distance in the Andersen test for females (26 m; 95% CI, 3 to 49) in favor of SG. In conclusion, a 10-week stay at the Danish Christmas Seal Home resulted in clinically relevant improvement in fat percentage and cardiometabolic fitness in socially vulnerable children, regardless of the program type.

PURPOSEThis study aimed to determine the acute and chronic effects of interval aerobic exercise on hepcidin, ferritin, and liver enzymes in adolescents with beta-thalassemia major.METHODSTwenty-six beta-thalassemia major adolescents referred to the Thalassemia Clinic and Research Center were selected as study participants and randomly divided into control (n = 13) and training (n = 13) groups. Participants performed 3 sessions per week for 45 minutes in each session for 8 weeks of aerobic interval exercise with an intensity of 50% to 65% of the heart rate reserve. Blood samples were taken before, immediately after the exercise session, and 48 hours after the last training session, and liver enzymes aspartate aminotransferase, alanine aminotransferase (ALT), alkaline phosphatase (ALP), ferritin, and hepcidin were evaluated.RESULTSThe results showed a decrease in aspartate aminotransferase, ALT, ALP, ferritin, and hepcidin levels due to 8 weeks of aerobic interval training (P = .14, P = .97, P = .03, P < .001, P < .001; respectively). Intergroup changes in all variables except ALT and hepcidin were significant (P < .05). Besides, acute aerobic exercise increased levels of aspartate aminotransferase, ALT, ferritin, and hepcidin (P = .04, P = .52, P < .001, P < .001; respectively), whereas ALP levels decreased (P < .001). In addition, changes in ALP and hepcidin levels were significant between the 2 groups (P = .05, P < .001; respectively).CONCLUSIONBased on the study's results, it can be concluded that 8 weeks of aerobic interval training can decrease ferritin and hepcidin levels, but acute aerobic exercise increases them.

PURPOSEStudy on the effect of psychological skills training on self-esteem (SE) in young athletes.METHOD10 swimmers and 35 volleyball players, split into an intervention group (25) and a control group (18). The intervention entailed a 3-week psychological skills training program covering arousal management, breathing, relaxation, mental imagery, and self-talk. Multilevel growth curve analyses evaluated SE changes.RESULTSThe intervention group showed significant improvements in multiple SE dimensions-physical self-worth, fitness, athletic competence, strength, and body attractiveness but not general SE.CONCLUSIONSThis study provides initial evidence of a multimodal psychological skills training's effectiveness in enhancing young athletes' domain-specific SE. It highlights the role of domain-specific SE in young athletes' well-being. Future research should examine psychological and physiological correlations and assess the long-term SE development in adolescent athletes.

An extensive number of publications have examined cross-education effects with adults, primarily investigating contralateral homologous (same) muscles. There are far fewer investigations on cross-education effects on contralateral heterologous (different) muscles and age (youth vs adult) and no studies investigating sex differences. Hence, the objective was to compare cross-education in female and male youth and young adults to contralateral homologous (chest press [CP], elbow flexors and extensors, handgrip isometric strength, and shot put) and heterologous (leg press, knee extension isometric strength, and countermovement jump) muscles. Twenty-eight female adults, 28 female youth, 28 male adults, and 28 male youth (total: 112) were examined before and after an 8-week (3 sessions/wk) unilateral, dominant arm, CP training program. Unilateral testing assessed dominant and nondominant leg press and CP 1-repetition maximum, knee extensors, elbow extensors, elbow flexors, and handgrip maximum voluntary isometric contraction (MVIC) strength, as well as shot put distance and countermovement jump height. Unilateral CP training induced training specific (CP 1-repetition maximum) and nonspecific (elbow extensors, elbow flexors, handgrip MVIC force, and shot put distance) improvements (P < .04, η2: .45-.85) but no significant lower body improvements. There was evidence for testing limb specificity as the dominant arm provided significantly (P < .021, η2: .17-.75) greater training gains than the nondominant arm. Youth's training adaptations exceeded with unilateral CP 1-repetition maximum, elbow extensors MVIC force, and shot put distance (P < .049, η2: .14-.49). No sex main effect differences were apparent. In conclusion, cross-education was training specific (greatest gains with upper body and dominant limbs) with greater benefits for youth and generally no sex differences with the exception of elbow extensors MVIC.

PURPOSETo investigate (1) whether physical activity is associated with lung function in children and adolescents, (2) whether this association is modified by the subjects' weight status, and (3) whether this association is mediated by the body mass index.METHODSThis is a cross-sectional study including 460 participants aged 7-17 years, randomly selected from 13 public schools in southern Brazil. Collected data included anthropometric measures, physical activity, screen time, and spirometric measures expressed as percent predicted values. Data were analyzed using multiple linear regression and 2-way analysis of variance.RESULTSThere were positive associations between physical activity and forced vital capacity (β = 3.897, P = .001) and forced expiratory volume in the first second (β = 2.931, P = .021). The effect modification by weight status was not statistically significant (forced vital capacity: Pinteraction = .296 and forced expiratory volume in the first second: Pinteraction = .057). Body mass index did not mediate the association between physical activity and spirometric outcomes (P > .05).CONCLUSIONRegular physical activity was associated with higher forced vital capacity and forced expiratory volume in the first second in children and adolescents. The observed associations were not modified by weight status nor mediated by body mass index. Our results reinforce the importance of regular physical activity for the development of lung function during childhood and adolescence.

PURPOSEThis study examined longitudinal associations between average physical activity (PA) levels in children and their sleep duration, and whether changes in PA levels are associated with their sleep duration.METHODSData were collected on 108 children at 4 time points: when children were 6, 12, 18, and 24 months of age (44% female, 50% Non-Hispanic White). PA was assessed using accelerometry. Children's daytime, nighttime, and 24-hour sleep duration were measured with actigraphy. Linear mixed model analyses estimated the associations between average PA levels over time and changes in PA over time, treating each sleep duration variable as an outcome in separate linear mixed model analyses.RESULTSChildren with higher total PA levels slept less during the day compared with children with lower total PA levels over the 2-year period. The strength of the relationship between a child's PA levels and their 24-hour sleep duration decreased as they approached 24 months of age.CONCLUSIONSThe results suggest that while PA may be developmentally beneficial overall, it appears that its relationship with sleep duration is not clinically relevant in very young children.

Purpose: This study examined the impact of an 8-week corrective dance intervention on thoracic hyperkyphosis, scapular position, breathing, and happiness in girls aged 10-12 years.
Methods: Sixty participants were randomly assigned to either an experimental (EX) or control (CO) group. The intervention involved rhythmic and corrective movements conducted 3 times a week. Measurements were taken before and after the intervention for thoracic hyperkyphosis angle, scapular position, lung function, and happiness levels.
Results: EX showed greater improvements (P = .001) than CO for the decrement of thoracic hyperkyphosis angle (48.20-42.80°) than in CO (47.66°-46.59°), and scapular position improved more (P = .003) in EX (1.48°-1.20°) than in CO (1.44°-1.42°). Forced vital capacity (P = .001) and forced expiratory volume in 1 second (P = .001) significantly increased in EX (FVC: 2.65-3.40 L; FEV1: 2.32-2.74 L), while they remained stable in CO. Happiness levels significantly improved (P = .001) in EX (42.20-49.79) and slightly decreased in CO (41.80-40.15).
Conclusions: The 8-week dance program improved posture, scapular position, breathing, and happiness in girls aged 10-12 years. It enhances physical health, emotional well-being, and social skills in children and adolescents.

Purpose: This study examined the effectiveness of an early childhood educator (ECE)-focused physical activity e-Learning course on children's physical activity and sedentary time in childcare.
Methods: A cluster randomized controlled trial was conducted in 12 childcare centers in London, Ontario, Canada. A total of 145 preschoolers and 42 ECEs participated in this study. ECEs in the intervention condition completed a 5-hour e-Learning course related to physical activity. Outcomes were preschoolers' minutes of moderate- to vigorous-intensity physical activity, light-intensity physical activity, and sedentary time assessed using accelerometers.
Results: The intervention did not have a significant effect on moderate- to vigorous-intensity physical activity (d < 0.01, P = .984), light-intensity physical activity (d = -0.17, P = .386), or sedentary time (d = 0.07, P = .717) from baseline to postintervention. There was also no significant intervention effect on moderate- to vigorous-intensity physical activity (d = 0.27, P = .260), light-intensity physical activity (d = -0.08, P = .740), or sedentary time (d = -0.15, P = .520) from baseline to follow-up.
Conclusions: Providing ECEs with online training in physical activity through an e-Learning course may not be sufficient to increase physical activity levels among young children in their care. It may be essential to deliver multicomponent interventions to increase preschoolers' engagement in physical activity in childcare.
