RESUMO

OBJECTIVES: This study aims to examine the independent and combined associations of 24-Hour Movement Guidelines for physical activity, screen time, and sleep duration with academic achievement in adolescent males and females. DESIGN: Cross-sectional study. METHODS: 1290 Spanish adolescents (565 females), aged 11 to 16 years (13.06 ±â€¯0.84), participated in this study. Self-reported physical activity, screen time, and sleep duration questionnaires were assessed. Academic achievement was calculated as an average score of the adolescents'' grades in first language (Spanish), first foreign language (English), and mathematics subjects. A multiple linear regression model was used to examine the association between meeting 24-Hour Movement Guidelines and academic achievement. Covariates included age, sex, socioeconomic status, body mass index, and cardiorespiratory fitness. RESULTS: Not meeting any of the three 24-Hour Movement Guidelines was associated with lower academic achievement in the whole sample (p < 0.001). Meeting physical activity and sleep duration guidelines, both independently and together, was associated with higher academic achievement in the whole sample (p < 0.001). Meeting at least two recommendations was associated with higher academic achievement in males (p < 0.01). However, trend analysis revealed that participants who met two or three recommendations had higher academic achievement compared to those who met one or none of these recommendations (p < 0.05). All these results were similar for males and females. CONCLUSIONS: Our findings suggest the importance of promoting more than one 24-Hour Movement Guidelines, mainly physical activity and sleep duration, which seems to contribute positively to increased academic performance in adolescents.

RESUMO

(1) Background: Adolescence is a critical stage in the development of healthy habits. In this regard, physical activity has emerged as a useful tool to improve satisfaction with life and health-related quality of life in adolescents. Therefore, the aim of the present study was to examine the mediating role of physical activity in the relationship between satisfaction with life and health-related quality of life in adolescent boys and girls. Also, we aimed to investigate the differences between sexes in the HRQoL, physical activity level, and satisfaction with life. (2) Methods: A total of 297 adolescents, ranging in age from 11 to 12 years (11.46 ± 1.63), participated in this cross-sectional study. The Satisfaction with life scale, Physical activity Questionnaire for Adolescents and the KIDSCREEN-10 questionnaires were employed. (3) Results: The estimated indirect effect showed that physical activity level was a mediator of the positive effect of satisfaction with life on health-related quality of life (ß = 0.105, 95% CI = 0.031; 0.202). However, the index of moderated mediation showed that sex is not a significant moderator of the mediating role of physical activity in the relationship between satisfaction with life and HRQoL (ß = -0.033, 95% CI = -0.023, 0.136). Furthermore, significant differences in satisfaction with life were found, with girls manifesting lower values (p-value = 0.026). (4) Conclusion: This study shows the importance of physical activity during adolescence and the association of this behavior with the health-related quality of life of adolescents.

RESUMO

This study aimed to analyze the association between specific dimension (i.e., fitness, appearance, physical competence, physical strength, and self-esteem) of students' physical self-concept (PSC) and their physical activity (PA) levels (i.e., intentions to be physically active and out-of-school PA levels perceived by students) and sedentary behavior (SB) (i.e., total sitting and screen time perceived by students). We also tested the role of students' motivation (i.e., intrinsic motivation and amotivation) towards PA in these relationships. A total of 1998 Spanish male (n = 1003) and female (n = 995) secondary students, aged between 13 and 17 years (M = 14.92, SD = 0.87) from 22 schools, enrolled in third grade (n = 1081) and fourth grade (n = 917), completed the self-reported questionnaires. Five independent structural equation modeling (SEM) adjusted by students' sex was used to examine the association between specific dimension of students' PSC (i.e., fitness, appearance, physical competence, physical strength, and self-esteem) and self-reported PA and SB variables, and to test the role of students' motivation in these relationships. Overall, most of students' PSC dimension positively predicted students' PA outcomes, and were negatively associated with SB. In addition, most of students' PSC dimension were positively associated with intrinsic motivation, and negatively predicted amotivation. In turn, intrinsic motivation was a positive predictor of PA outcomes, and a negative predictor of SB, whereas amotivation was a negative predictor of PA outcomes and sitting time, and a positive predictor of screen time. Finally, from PSC dimensions, sex as a covariate was a positive predictor of intrinsic motivation and PA outcomes, and was a negative predictor of amotivation and sitting time. These findings suggest the importance of the specific dimensions of PSC perceived by adolescents on their motivational processes, and in turn, on their PA and SB outcomes.

RESUMO

Adolescence is a critical period for the acquisition of health-related behaviors that will transcend later psychological well-being in adulthood. The present study presents a theoretical model whose objective is to analyze how physical activity predicts an adequate quality of life through self-concept and subjective happiness among adolescents. A total of 452 students aged 12 to 15 (M = 13.8; SD = 0.77) from four Compulsory Secondary Education institutes of the Autonomous Community of Extremadura participated, including boys (n = 258) and girls (n = 194). The students reported information on the following variables: physical activity, body mass index, self-concept, subjective happiness, and quality of life. The results show acceptable fit indices for the proposed theoretical model, which showed the importance of physical activity through self-concept and subjective happiness in quality of life: MRLχ2 = 67.533, p < 0.05, CFI = 0.93, TLI = 0.90, SRMR = 0.05, and RMSA = 0.07. Likewise, the model presented a better fit index for males than females. This study draws conclusions on the importance of physical activity as a predictor of quality of life mediated by the perception of self-concept and mood in adolescents.

RESUMO

A growing number of studies have highlighted the health benefits of high physical activity, low screen time, and optimal sleep duration among school-age children and adolescents. Objective: The present study proposes to examine the individual and combined association between movement behaviors (physical activity, screen time, and sleep time) and quality of life in boys and girls. Method: A total of 319 Spanish primary and secondary school students participated in the study. Physical activity, screen time, sleep duration, and quality of life were evaluated. Results: Descriptive, correlation, and regression analyses were carried out in order to improve knowledge about health-related behaviors for all participants. The results found significant positive associations between physical activities and sleep time with quality of life. Finally, the regression models showed that physical activity scores predict quality of life, especially in children. It is concluded that movement behaviors are important in association with quality of life. Likewise, the impact of physical activity on the quality of life is highlighted as the main behavior in the prediction of the quality of life for a population of school adolescents.

RESUMO

INTRODUCCIÓN: en España, un tercio de los jóvenes de 7 a 14 años de edad tienen sobrepeso y obesidad. Los comportamientos relacionados con la salud, como un alto nivel de actividad física, un tiempo de pantalla bajo y una buena alimentación, pueden prevenir el sobrepeso y la obesidad en los jóvenes. OBJETIVOS: conocer la adherencia a la dieta mediterránea y la calidad del patrón alimentario de los adolescentes extremeños. MÉTODO: la presente investigación es un estudio descriptivo transversal en el que participaron 1566 adolescentes de 12 a 14 años: 857 chicos (13,12 ± 0,89) y 709 chicas (13,05 ± 0,82). La actividad física se registró a través del cuestionario de actividad física para adolescentes. El tiempo de pantalla se analizó mediante el cuestionario de comportamiento sedentario en el tiempo libre para jóvenes. La adherencia a la dieta mediterránea se calculó mediante el cuestionario KIDMED. RESULTADOS: el 24,5 % de los adolescentes reportaron tener una buena adherencia a la dieta mediterránea. Los escolares con menor edad (p < 0,001) presentaron un patrón de alimentación mejor, sin diferir entre géneros ni índices de masa corporal. Los estudiantes que cumplían las recomendaciones de actividad física y tiempo de pantalla presentaron una adherencia a la dieta mediterránea mayor (p < 0,01). CONCLUSIONES: los resultados mostraron que la mayoría de los adolescentes necesitaban mejorar su patrón alimentario. Los participantes que cumplían las recomendaciones de actividad física y tiempo de pantalla presentaron una mayor adherencia a la dieta mediterránea

RESUMO

BACKGROUND: Adolescence is a critical period for neurodevelopment, it is characterised by the establishment of behavioural patterns that can affect children's physical, mental and cognitive health, both immediately and later in life. OBJECTIVE: The aim of the present research was to examine the association between adherence to the Mediterranean diet (MeD) and academic performance, as well as to analyze the moderating role of body mass index (BMI) status in this relationship. METHODS: This cross-sectional study had a total 1290 adolescents (13.07 ± 0.82 years old, 714 boys and 576 girls) aged 12-14 years were included in this study. Adherence to the MeD was assessed using the Mediterranean Diet Quality Index. Academic performance was assessed through school records using four subjects: language, mathematics, English and grade point average (GPA). RESULTS: Results showed a positive association between adherence to the MeD and all academic indicators after adjusting for potential confounders (ß ranging from 0.165 to 0.213, all p < 0.001). The group of good adherence to the MeD had significantly higher scores in all the academic indicators compared with the poor/average group (p < 0.01). No interaction was found between BMI status and adherence to MeD in relation to academic indicators (all p > 0.340). These differences remained significant for both normal weight and overweight/obesity groups (p < 0.01). CONCLUSIONS: Our results suggest that adherence to the MeD may be positively associated academic performance on adolescents regardless, of BMI status.

RESUMO

The aim of this study was to investigate the motivations for beginner runners to take part in Parkrun Poznan and City Trail Poznan, Poland, taking into account their socio-demographical variables. A total of 165 (age: 36.33 ± 10.38) inexperienced runners participated in the diagnostic survey and completed the MOMS (Motivations of Marathoner Scale) questionnaire. The sample consisted of 82 men (49.7%) and 83 women (50.3%). The results showed that men were more likely to start running due to competition-related motivations, while the motivations of women were more often related to affiliation, psychological coping, life meaning, and self-esteem. As age increased, the level of motivation due to personal goal achievement, competition, and recognition scales decreased. The Affiliation Scale was especially important for singles who started running, in comparison with runners who were married or in a relationship. These factors should be taken into consideration by event managers and public health specialists. Promoting safe running among people who have no experience with this sport is as important as encouraging them to run. All runners stated that they would like to run a marathon in the future. Moreover, thanks to initiatives such as City Trail and Parkrun, Polish respondents feel motivated to lead an active lifestyle, with an average score of 4.98 on a 7-point Likert scale.

RESUMO

Resumen Objetivo. Analizar la relación entre el Índice de Masa Corporal (IMC) percibido y la actividad física (AF) en adolescentes. Método. Participaron 605 adolescentes con edades comprendidas entre los 12 y los 15 años. Se valoraron las variables percibidas para el peso, la altura y el nivel de AF mediante un cuestionario autoinformado. Resultados. Se encontraron asociaciones significativas entre el IMC percibido y el nivel de AF. El análisis de regresión mostró que el IMC percibido sirve para predecir el nivel de AF. El análisis de la covarianza demostró la existencia de diferencias significativas entre los adolescentes con sobrepeso y obesidad frente a los normopeso. Conclusión. Se ha demostrado que los adolescentes que realizan menos AF tienen una mayor probabilidad de sufrir sobrepeso y obesidad.


Abstract Objective. The objective of this research is to analyse the relationship between the perceived body mass index and physical activity in adolescents. Method. A total of 605 adolescent students between 12 and 15 years old participated. The variables for perceived weight, height and physical activity level were assessed using a self-report questionnaire. Results. The results showed significant associations between the perceived body mass index and the physical activity level. The regression analysis showed that the perceived body mass index serves to predict the physical activity level. The analysis of covariance, demonstrated the existence of significant differences between overweight and obese adolescents versus those of normal weight. Conclusion. It has been shown that adolescents who perform less PA are more likely to be overweight.

RESUMO

The purpose of this research was to describe reasons for participating in a marathon and their association with marital status, age, and sex. Four hundred and ninety-three runners in total, 144 of whom were women and 349 of whom were men, completed the Polish version of the Motivations of Marathoners Scale (MOMS), containing nine dimensions, which was released through an online survey at the Poznan Marathon in Poland (2019). Athletes' age (ranges 19-25, 26-35, 36-50, 51-70 years) and marital status (single, married, divorced) were asked of the participants. The results showed that statistical significant associations were found between athletes' motivational aspects and athletes' sex and age. To this end, three MOMS dimensions were statistically associated with athletes' sex, a further three dimensions were different age-wise, and, lastly, marital status did not show differences in any of the dimensions. Moreover, statistical differences were not found in the multivariate analysis comparing marital status, sex, and age range according to MOMS. Recreational runners' reasons for participating in a marathon are different depending on certain sociodemographic variables; therefore, these characteristics should be considered when addressing different athletes in order to provide them with the most suitable information for taking part in such events.

RESUMO

INTRODUCTION: There are not many valid instruments to quickly and easily identify body dissatisfaction in adolescents. Most studies have used the Stunkard Rating Scale to assess body image. Nevertheless, this scale has been described as too abrupt and crude for adolescents. AIM: Was to validate the body image dimensional assessment (BIDA) questionnaire in a sample of adolescents from Secondary schools of Spain. METHOD: The BIDA consists of four items to answer with reference to a series of four silhouettes using a numeric scale that allows the quantification of the degree of body dissatisfaction (BD), sexual body dissatisfaction (SxBD), comparative body dissatisfaction (CBD) and the calculation of the final body dissatisfaction index (BDIndex). The sample included 2059 adolescents, 1132 males and 929 females aged 13.10 ± 0.89. Participants answered the BIDA and then their anthropometrics measurements were taken. RESULTS: Reliability test, a convergent test and confirmatory factorial analysis were conducted to validate BIDA instrument. A single factor structure emerged from confirmatory factorial analysis; the BIDA demonstrated adequate internal consistency in adolescents: (CFI > 0.90, TLI > 0.90, α > 0.80). Significant correlations (p < 0.001) emerged between the BIDA indices and all the anthropometric measures. CONCLUSIONS: The BIDA questionnaire is a valid and reliable instrument to evaluate body dissatisfaction in Spanish adolescents. LEVEL OF EVIDENCE: Level V, descriptive study.

RESUMO

Active commuting to and from school (ACS) has been recognized as a potential tool to improve physical fitness. Thus, this study aims to test the relationships between the average slope in the ACS and physical fitness, as well as to verify the mediator role of fatness in the relationship between average slope and physical fitness. A total of 257 participants, 137 boys and 120 girls, from 22 schools belonged to first and second High School grades participated in this study. Based on self-reported measure and Google Earth, participants were grouped into the active commuter (number of trips was ≥5, and the time of the trip was ≥15 min), mixed commuter (number of weekly trips was <5, and the time spent on the trip was <15 min) and passive commuter groups (those who reported traveling regularly by car, motorcycle, or bus). Specifically, in the active commuter group, a positive association between the average slope in the ACS with fatness was found, which in turn was positively related to strength lower limbs and cardiorrespiratory fitness. The average slope was not significantly associated with physical fitness indicators. Furtheremore, fatness did not mediate the relathionship between average slope and physical fitness. This research concluded positive associations between average slope and the body fat in the ACS. The tendency of findings signal that the average slope should be taken into account along with the distance, time and frequency of the active commuting.

RESUMO

Running participation has increased significantly in the last decade. Despite its association with different health-related aspects, athletes may experience adverse outcomes, including injuries. The aim of this study was twofold: to examine the relationship between runners' resilience levels, motivation and incidence of injury, on the one hand; and to analyse the mediation that intrinsic and extrinsic motivation has on the association between the number of injuries and psychological resilience levels among amateur athletes. The sample consisted of a total of 1725 runners (age: 40.40 ± 9.39 years), 1261 of whom were male (age: 43.16 ± 9.38), and 465 of whom were female (age: 40.34 ± 9.14). Athletes completed the Behavioural Regulation in Exercise Questionnaire (BREQ-3), the Resilience scale (CD-RISC 10), and an Injury retrospective survey. Three mediation models were constructed, and the results showed a significant indirect association of athletes' intrinsic motivation and resilience on the number of injuries (ß = 0.022, CI = 0.007, 0.0) in mediation model 1, whereas extrinsic motivation was found to have no significant association on those variables (ß = -0.062, CI = -0.137, 0.009) in mediation model 2. Model 3 showed significant differences with respect to resilience (p < 0.05) and intrinsic motivation (p < 0.05). Therefore, the mediation of intrinsic motivation on athletes' resilience levels and incidence of injury was demonstrated, i.e., it was found that intrinsic motivation was associated with a higher incidence of injury, while no such correlation was found for extrinsic motivation. This study shows that the amateur long distance runners with a high level of intrinsic motivation tend to suffer from a greater number of injuries, and at the same time psychological resilience was associated with a lower number of injuries.

RESUMO

The aim was to analyze the extent to which anthropometric values, in line with body image and physical ability, predict physical self-concept, and the latter, in turn, predicts the practice and intention to pursue physical activity. A total of 302 participants, 150 males and 152 females were recruited from different primary schools in Extremadura (Spain). The age of the participants ranges from 10 to 13 years old (M = 11.74; SD = 0.86). The indirect effects of the model showed significant relationship between physical condition (p = 0.001) and PA levels, according to the perception of self-concept [ß = 0.231, 95% BcCI = (0.055, 0.212)]. However, anthropometric variables proved not to be related to any significant extent (p < 0.05). The second level covered the indirect effects between the intention to be physically active and self-concept, which showed a significant relationship between the perception of self-concept (p = 0.000) and the intention to be physically active. Last, the third level showed significant relationships between physical condition (p = 0.001) and the intention to pursue physical activity. The present investigation concluded that physical condition, anthropometric variables, and body image predict the perception of physical self-concept in adolescents. Finally, this article highlights the importance of body image perception, anthropometric values, and physical condition in the intention of being physically active. In addition, it highlights the mediating role of physical self-concept to develop physical activity.

RESUMO

Background: The aim of this systematic review was to examinemotivational interventions based on physical activity as precursor of psychosocial benefits inside of the scholar context. Method: studies were identified in seven databases (Web of Science, Sport Discuss, Scopus, Eric, Pubmed, Psycinfo and Google Scholar). The search process was from June 2011 to September 2019. A total of 41 articles met the inclusion criteria. Results: 23 studies showed psychological effects after intervention and also 10 studies showed psychosocial effect after the intervention. The rest of the studies, although they presented changes, did not become significant.Conclusions: this systematic review showed the importance of motivational processes for the performance of physical activity and sport as a precursor of psychosocial changesand highlights the importance of strategies and the temporal nature of studies to maintain significant changes over time.Likewise, the study shows the future trend of motivational interventions, highlighting the female gender as participants of special interest, and changing the methodology through web-based interventions and active breaks or mental breaks during traditional subject classes.

RESUMO

Framed within Self-Determination Theory, the objective of this study was to analyze the relationship between satisfaction and frustration of basic psychological needs, levels of motivation, physical activity, and satisfaction with life. METHODS: A total of 487 students participated, comprising males (n = 262) and females (n = 225), aged between 14 and 16 years (M = 15.02; SD = 0.87), from different secondary schools. RESULTS: A regression analysis was carried out (structural equation modeling) that revealed the existence of two theoretical lines, one positive and the other negative, where the satisfaction of basic psychological needs was positively related to autonomous motivation and physical activity, which predicted satisfaction with life. On the other hand, the frustration of basic psychological needs was positively related to controlled motivation, whereas controlled motivation (introjected regulation and extrinsic regulation) was inversely associated with physical activity and satisfaction with life. CONCLUSION: The results show the importance of motivational processes in physical activity, and the effects of physical activity on satisfaction with life in adolescents who spend more time engaged in physical activity.
