Effects of Physical Activity on Cognition, Behavior, and Motor Skills in Youth with Autism Spectrum Disorder: A Systematic Review of Intervention Studies.

The aim of this paper was to analyze the acute and chronic effects of physical activity (PA) on cognition, behavior, and motor skill in youth with autism spectrum disorder (ASD), taking into account potential confounders. In addition, it was intended to elaborate a guide of educational applications with strategies for PA use. Studies were identified in four databases from January 2010 to June 2023. A total of 19 interventional studies met the inclusion criteria. PA programs ranged from two weeks to one year in duration, with a frequency of one to five sessions per week. More than 58% of the studies showed positive effects of PA on cognition, and 45.5% on behavior and motor skill. Moderate-vigorous PA for 15-30 min has shown acute effects on cognition, general behavior, and stereotypic/repetitive behaviors in youth with ASD. A total of 9 out of 14 studies showed chronic effects on general behavior and stereotypic behaviors, and only 6 on motor skills.

Effect of an Integrated Active Lessons Programme through Playful Maths Games on Self-Concept, Self-Esteem and Social Skills in Preschool Children.

The aim of this study was to analyse the effects of an integrated active lessons programme based on playful math games, of 10 weeks' duration (30 min/day × 2 days/week), on self-concept, self-esteem and social skills in preschool children. One hundred and ninety-four preschool children (53.6% girls) aged 53.36 ± 11.82 months were split into a control group (CG) and an experimental group (EG). The EG improved significantly in self-concept compared to the CG in boys and girls (6.8% and 7.1%, respectively). Personal and academic self-esteem levels increased significantly (8.1% and 5.5%, respectively, only in girls). Although the EG obtained significant improvements in social self-esteem and social skills compared to the beginning of the study, these results were not found in comparison with the CG. The introduction of active lessons based on playful maths games within the classroom is recommended as support for the improvement in self-concept, self-esteem and social skills in early childhood education.

Alternatives of Physical Activity within School Times and Effects on Cognition. A Systematic Review and Educational Practical Guide / Las alternativas de actividad física en horario escolar y sus efectos en la cognición. Una revisión sistemática y guía práctica educativa

This review analyses educational intervention studies that have researched the effects of physical activity in school on schoolchildren's cognition. Twenty-nine intervention studies carried out between January 2005 and the end of June 2019 were retrieved from five databases. Fourteen papers analysed the physically activity in academic lessons (PAAL) method, nine analysed the effects of active lesson breaks (ALB), two analysed active recess (AR) intervention, and three analysed combined physical activity (CPA) interventions consisting of two or more types of physical activity. Physical activity in school time has acute and chronic positive effects on cognition in children. In all the interventions (PAAL, ALB, AR, and CPA) short-term high-intensity physical activity sessions improved cognitive performance. Medium- to long-term moderate vigorous physical activity sessions also produced improvements in cognitive performance. The implications of including CPA programmes in the school timetable are discussed and practical guidelines with recommendations are offered

Esta revisión analiza los estudios de la intervención educativa que han investigado los efectos de la actividad física en el contexto escolar en la cognición del alumnado. Veintinueve estudios de intervención llevados a cabo entre enero de 2005 y finales de junio de 2019 fueron seleccionados de 5 bases de datos diferentes. Catorce artículos analizaron el método de lecciones académicas físicamente activas (PAAL), nueve analizaron los efectos de descansos activos (ALB), dos analizaron las intervenciones de recreos activos (AR) y tres analizaron las intervenciones de actividad física combinada (CPA) compuestas al menos por dos o más tipos de actividad física. Los hallazgos muestran que la actividad física en horario escolar tiene efectos positivos agudos y crónicos en la cognición de los estudiantes. En todas las intervenciones (PAAL, ALB, AR y CPA) las sesiones de actividad física de gran intensidad y breves en el tiempo mejoraron el rendimiento cognitivo. A medio-largo plazo, las sesiones de actividad física de intensidad moderada-vigorosa también produjeron mejoras en el rendimiento cognitivo. Se discute la implicación de incluir programas de CPA durante el horario escolar y se ofrece una guía práctica con sugerencias educativas para la implantación de estos estímulos en el contexto educativo

48-Hour Effects of Monitored Cooperative High-Intensity Interval Training on Adolescent Cognitive Functioning.

Physical activity has been positively related to better cognitive performance though the effects of varied exercise type and intensity and the duration of cognitive benefits are unclear. This study analyzed the effect of 16 minutes of monitored cooperative high-intensity interval training (monitored C-HIIT) at the start of the school day, on various cognitive variables over the next 24-48 hours. We randomly assigned 158 participants either to a control group ( n = 81) that engaged only in static stretching or to an experimental group ( n = 77) that performed monitored C-HIIT. We assessed cognitive functioning before the exercise, immediately afterward, and for five follow-up time points over the next two days (i.e., at 2, 3, 4, 24, and 48 hours). We analyzed age, sex, body mass index, and moderate-to-vigorous physical activity as potential confounder variables. Adolescents in the monitored C-HIIT group increased selective attention by 17.39% during the next hour ( p = .015) and increased concentration by 20.31% and 15.26% during the first ( p = .022) and second ( p = .059) subsequent hours, respectively. This positive short-term benefit of monitored C-HIIT during immediate subsequent hours is an important finding with implications for the school curricula and schedule.

Apoyo parental percibido y motivación adolescente hacia la actividad física / Perceived parental support and adolescents' motivation toward physical activity / Apoio parental percebido e motivação adolescente para a atividade física

Este estudio pretendió conocer en qué medida diferentes formas de apoyo social materno y paterno incrementaban el porcentaje de varianza explicada de motivación autodeterminada hacia la práctica de actividad físico-deportiva de sus hijos, más allá de la proporción atribuida a un conjunto de variables personales (sexo, edad e índice de masa corporal). Cuatrocientos sesenta y nueve adolescentes (50.3% chicas) con edades comprendidas entre los 12 y los 16 años de edad participaron en el estudio. Los instrumentos empleados fueron una adaptación al castellano de la Activity Support Scale y del Behavioral Regulation in Exercise Questionnaire-2. El análisis estadístico principal consistió en un procedimiento de regresión jerárquica. Los resultados revelaron que para el caso de la motivación identificada el porcentaje de varianza explicada por el modelo ascendió hasta el 25%. Además del sexo y la edad, el apoyo instrumental atribuido a madres y padres contribuía a la explicación de la variabilidad observada. Respecto a la motivación intrínseca, el porcentaje de varianza explicada fue del 27%. Más allá del sexo, el apoyo instrumental materno y paterno contribuyeron a la explicación de la variabilidad observada. La percepción juvenil de la provisión de recursos materiales y económicos se asoció con una orientación motivacional que destaca los beneficios que aporta, así como el disfrute y satisfacción que se deriva de la realización de actividad física

This study aimed to know to what extent different types of parental social support increased the percentage of explained variance for self-determined motivation toward physical activity practice of their children, apart from other variables such as gender, age, and body mass index. Four hundred and sixty-nine adolescents (50.3% female) aged between 12 and 16 years participated in this study. The Spanish adaptations of the Activity Support Scale and the Behavioral Regulation Exercise Questionnaire-2 were used to assess parental support for children's physical activity and self-determined motivation toward physical activity (PA), respectively. A hierarchical linear regression procedure was used for the main statistical analysis. Our results revealed that regarding identified motivation, the percentage of variance explained by the model increased to 25%. In addition to gender and age, parental instrumental support contributed to explain the observed variability. As for intrinsic motivation, the percentage of explained variance was 27%. Besides gender, perceived provision of maternal and paternal instrumental support were contributors to the observed variability. In conclusion, children's perception of the provision of material and financial resources was associated with a motivational orientation that emphasizes the benefits, enjoyment and satisfaction of performing physical activity

Apoyo parental para realizar actividad física en escolares de 6 años de edad: influencia sobre el estado nutricional y fitness / Parental support for physical activity in schoolchildren and its influence on nutritional status and fitness

Resumen: Introducción: Los padres son modelos fundamentales para trasmitir y enseñar hábitos de vida salu dable a sus hijos. Nuestro objetivo fue determinar la influencia del apoyo económico, motivacional y acompañamiento de los padres a sus hijos para realizar actividad física (AF) y su relación con el estado nutricional y capacidad cardiorrespiratoria en los escolares. Sujetos y Método: Estudio de corte transversal que incluyó a 70 escolares de seis años. Los padres completaron el cuestionario "The Parental Influence on Physical Activity Scale". Las variables antropométricas se midieron según la Norma Técnica Ministerial chilena para la supervisión de niños de 0 a 9 años, la intensidad de la AF se midió con acelerómetros triaxiales GT3X y la estimación del VO2máx se realizó utilizando el test Course de Navette. Resultados: El índice de masa corporal fue de 17,9 ± 2,9 kg/m2, la prevalencia de obesidad y el VO2máx fueron de 57,1%, y 38,05 ± 16,9 ml/kg/min, respectivamente. La AF moderada durante la clase de educación física (EF) fue significativamente mayor en niños en comparación a niñas (p < 0,006). El apoyo económico y motivacional de los padres no influyó significativamente en el peso corporal, IMC, perímetro de cintura, intensidad de la AF y VO2máx de los niños. Los niños acompañados por sus padres presentaron diferencias significativas con la AF moderada realizada en EF en comparación con quienes no eran acompañados (p = 0,023). Conclusiones: Acompañar a los hijos a realizar AF influye en la AF moderada que realizan los escolares en EF. Se debería continuar con este tipo de estudio y medir la AF diariamente.

Abstract: Introduction: Parents are key models for transmitting and teaching healthy lifestyle habits to their children. Our objective was to determine the influence of the economic and motivational support, and parental involvement in their children physical activity (PA) and its relationship with nutritio nal status and cardiorespiratory fitness. Subjects and Method: Cross-sectional study which included 70 six-year-old schoolchildren. Parents completed the "The Parental Influence on Physical Activity Scale" questionnaire. Anthropometric variables were measured according to the Chilean Ministerial Technical Standard for the supervision of children from 0 to 9 years old; PA intensity was measured with triaxial accelerometers GT3X and the VO2max estimation was performed using the Navette Course test. Results: The average body mass index was 17.9 ± 2.9 kg/m2, the obesity prevalence and VO2max were 57.1%, and 38.05 ± 16.9 ml/kg/min, respectively. Moderate PA during the physical education (PE) class was significantly higher in boys compared to girls (p < 0.006). The economic and motivational support of the parents did not significantly influence the body weight of the children, BMI, waist circumference, PA intensity, and VO2max. Children supported by their parent showed significant differences with moderate PA performed in PE compared to those who were not suppor ted by parents (p = 0.023). Conclusions: Parental support of their children in performing physical activity influences the levels of moderate PA that they do during PE classes. This type of study should be continued and the PA should be measured daily.

Acute and chronic effect of physical activity on cognition and behaviour in young people with ADHD: A systematic review of intervention studies.

BACKGROUND: Young people with attention deficit hyperactivity disorder (ADHD) often have learning and behavioral control difficulties. AIM: The aim of this review is analyse the acute and chronic effect of physical activity (PA) on the cognition and behaviour of children and adolescents with ADHD. METHODS: Studies were identified in five databases (PubMed, SPORTDiscus, ProQuest, Web of Science, and SCOPUS), from January 2000 through to January 2017. A total of 16 interventional studies met the inclusion criteria. RESULTS/CONCLUSIONS: PA practice of 20-30 min (intensity 40-75%) produces a positive acute effect on processing speed, working memory, planning and problem solving in young people with ADHD. However, these effects on behaviour are contradictory and vary depending on age. Chronic PA practice (≥30 min per day, ≥40% intensity, ≥three days per week, ≥five weeks) further improves attention, inhibition, emotional control, behaviour and motor control. The results must be treated with caution, because only 25% of the studies used confounders. IMPLICATION: More research is needed to justify the causes of these effects. It is necessary to establish programs with regard to the duration, intensity, kind of exercise, and time of PA to improve cognition and behaviour in young people with ADHD taking into account potential confounders.

Analysis of the Effect Size of Overweight in Muscular Strength Tests Among Adolescents: Reference Values According to Sex, Age, and Body Mass Index.

Martínez-López, EJ, De La Torre-Cruz, M, Suárez-Manzano, S, and Ruiz-Ariza, A. Analysis of the effect size of overweight in muscular strength tests among adolescents: reference values according to sex, age, and body mass index. J Strength Cond Res 32(5): 1404-1414, 2018-The aim of this paper is to quantify the effect size of overweight on the results of muscular strength tests in adolescents and to report percentile tables based on sex, age, and body mass index (BMI). The study hypothesized that the effect size obtained from the difference between normal-weight and overweight youth would be greater than the differences between sexes within the same age group. A total of 11,044 Spanish adolescents (48.5% girls) aged 14.39 ± 1.21 years (range: 12-16 years) from 42 secondary schools participated in the research. Muscular strength was evaluated using standing long jump, hand grip strength (manual dynamometer), and sit-ups (30 seconds). The effect size was analyzed using the adjusted Hedges' g. The results show that 76.3 and 72.8% of overweight boys and girls, respectively, performed a standing long jump equal to or less than the normal-weight average. The 67.4 and 67.1% of overweight boys and girls, respectively, showed manual dynamometer values equal to or greater than the normal-weight average. Finally, 68.7 and 65.9% of overweight boys and girls, respectively, obtained measures for 30 seconds of sit-ups equal to or lower than the normal-weight average. It can therefore be concluded that the differential effect size between boys and girls is higher than that between normal-weight and overweight adolescents in the 3 strength tests analyzed. Despite the above, these results suggest the value of taking into account the BMI when assessing the muscular strength of young people, in addition to sex and age.

Perfiles de orientación hacia la meta y su relación con indicadores de actividad físico-deportiva / Goal Orientation Profiles and Their Relation with Indicators of Physical Activity

Resumen El presente estudio examinó la motivación hacia la actividad física empleando la teoría de la orientación hacia la meta. Un total de 786 estudiantes participaron en este estudio. Un procedimiento de análisis de cluster jerárquico permitió identificar cuatro perfiles de orientación hacia la meta. El perfil más adaptativo (alta tarea/alto ego/altas expectativas) se asoció con la obtención de los mejores resultados. Se concluye que los jóvenes con una alta motivación hacia la tarea, alto ego y expectativas de ejecución obtienen las mayores muestras de apoyo por parte de familiares e iguales para la práctica de actividad física se perciben más autoeficaces para realizar dicha actividad, se atribuyen una mejor forma física autopercibida y manifiestan una práctica más frecuente de actividad físico-deportiva.

Abstract This paper researches motivation for physical activity in the framework of the goal orientation theory. This work is based on data from 786 students. Hierarchical cluster analysis allowed identifying four goal orientation profiles. The most adaptive profile (high task, high ego, high expectancy) is associated with the best results. Students with high motivation for physical activity, ego, and performance expectancy are concluded to obtain more indications of support from their relatives and peers for physical activity practice, perceive themselves self-effective to complete this activity, claim their better self-perceived fitness, and show more frequent physical-sports activity.

Efectos del ejercicio físico extracurricular vigoroso sobre la atención de escolares / Efeitos da actividade física extracurricular vigorosa em atenção o nível cognitivo em idade escolar / Effects of after-school, high-intensity physical activity programme, on levels of attention of school children

El objetivo de este trabajo fue analizar el efecto sobre la atención de escolares de dos programas de actividad física (moderada y alta intensidad). Participaron 94 niños (n = 52) y niñas (n =42), (Edad M = 8,20; DT = 0,70) de la ciudad de Granada (España). Se empleó un diseño cuasi-experimental con un grupo control y otro experimental. Se analizó amplitud de la atención y atención selectiva. Como variable de control se evaluó la aptitud cardiorrespiratoria a través de consumo de oxígeno máximo y la velocidad pico alcanzada durante actividad aeróbica máxima. Se aprecian efectos significativos a favor del programa de alta intensidad sobre dos pruebas de span atencional y ejercicios de atención selectiva, así como en valores de condición física. Se concluye que la práctica física de alta intensidad intermitente, practicada de manera regular, podría tener implicaciones positivas sobre el rendimiento cognitivo de niños y que la mejora de la condición física podría ser uno de los factores vinculados a estos cambios (AU)

The aim of this study was to analyze the effect of two programs of physical activity (moderate and high intensity physical activity), in the levels of attention of a sample of young in scholar aged. 94 children, boys=52 and girls=42 (Age M = 8.20; SD = 0.70) from Granada (Spain) participated in the investigation. A quasi-experimental design was used, with control and experimental group. Evidence of attentional span and search items on matrices with the purpose of analyzing the amplitude of the attention and selective attention were applied. As a control variable, cardiorespiratory fitness by maximum oxygen uptake and peak speed reached during maximal aerobic activity was evaluated. The results showed significant effects in favor of high-intensity program on two tests of attentional span and exercises selective attention, as well as the values of fitness. These data suggest that the physical practice of intermittent high intensity practiced regularly could have positive implications on cognitive performance of children and improving the physical condition could be one of the factors linked to these changes (AU)

Influencia del nivel de atracción hacia la actividad física en el rendimiento académico de los adolescentes / Influence of level of attraction to physical activity on academic performance of adolescents

El objetivo fue conocer el nivel de atracción hacia la actividad física y el rendimiento académico, así como la asociación entre dicha atracción y las calificaciones en las asignaturas de Matemáticas, Lengua y Educación Física en función del sexo, tras ajustar por edad e índice de masa corporal, en una muestra de 1009 adolescentes españoles (n chicas = 579) entre 12-18 años. Se usó el Children's Attraction to Physical Activity Questionnaire y la calificación de las asignaturas. Los análisis mostraron que el disfrute con la actividad física vigorosa es el principal factor de atracción que se relaciona, en chicas, con mejores calificaciones en Matemáticas y Lengua. En chicos, el disfrute con juegos y deportes, y con la práctica de actividad física vigorosa no influyen en su rendimiento académico, sin embargo aquellos que dan más importancia al ejercicio físico obtienen peores calificaciones en Lengua y Matemáticas. Se sugiere, por tanto, que a la conocida relación entre actividad física y rendimiento académico es necesario añadir que los factores de la atracción hacia la actividad física pueden relacionarse en buena medida con diferentes resultados de rendimiento académico en función del sexo.

The aim of this study was to examine the relationship between student level of attraction to physical activity and academic performance, and the association between attraction to physical activity and grades in the subjects of Maths, Spanish Language, and Physical Education according to gender, after adjusting for age and body mass index, in a sample of Spanish adolescents. The study included 1009 12-18 year-old students (579 girls).t. The Children's Attraction to Physical Activity questionnaire and numeric marks in the subjects were used. Analyses showed that enjoyment with vigorous physical activity is the main attraction factor related to higher grades in Maths and Spanish Language among girls. Among boys, enjoyment of games and sports, and vigorous physical activity is observed to have no impact on academic performance. However, lower grades were observed in Maths and Spanish Language among boys who give great importance to physical activity. Therefore, it is suggested that the well-known physical activity-academic performance relationship must take into account physical activity-attraction factors, as they may well have some impact on academic performance according to gender.

Influencia del desplazamiento activo sobre la felicidad, el bienestar, la angustia psicológica y la imagen corporal en adolescentes / Influence of active commuting on happiness, well-being, psychological distress and body shape in adolescents

Objetivo: Analizar la asociación entre el desplazamiento activo y los indicadores de salud psicológica en una muestra de 1012 adolescentes. Método: El desplazamiento activo se evaluó mediante cuestionario. La felicidad con la Subjective Happiness Scale, el bienestar y la angustia psicológica con el General Well-Being, y la imagen corporal con la versión breve del Body Shape Questionnaire. Resultados: Los/las adolescentes que emplean más de 15 minutos al día en desplazamiento activo tenían niveles más altos de felicidad subjetiva (p=0,032) y bienestar psicológico (p=0,036), así como niveles más bajos de angustia psicológica (p=0,021) que los/las que emplean 15 o menos minutos al día. No se hallaron diferencias significativas en la imagen corporal entre los/las adolescentes menos y más activos/as (p=0,163). Conclusión: Desplazarse de manera activa al instituto, durante más de 15 minutos al día, es una conducta recomendable que se asocia con un mayor nivel de felicidad y bienestar en la adolescencia (AU)

Objective: To analyse the association between active commuting to secondary school and indicators of psychological health in a sample of 1012 adolescents. Method: Active commuting was assessed through a questionnaire, subjective happiness with the Subjective Happiness Scale, well-being and psychological distress with the General Well-Being Scale, and body shape was assessed using the short version of the Body Shape Questionnaire. Results: Adolescents who spent more than 15minutes per day actively commuting to secondary school had higher levels of subjective happiness (p=0.032) and psychological well-being (p=0.021) and lower levels of psychological distress (p=0.021) than adolescents who spent 15minutes or less per day. There were no differences in body shape between less and more active adolescents (p >0.05). Conclusion: Active commuting to secondary school for more of 15minutes per day is recommended because it is associated with higher levels of happiness and well-being in adolescents (AU)

METHOD: Active commuting was assessed through a questionnaire, subjective happiness with the Subjective Happiness Scale, well-being and psychological distress with the General Well-Being Scale, and body shape was assessed using the short version of the Body Shape Questionnaire. RESULTS: Adolescents who spent more than 15 minutes per day actively commuting to secondary school had higher levels of subjective happiness (p=0.032) and psychological well-being (p=0.021) and lower levels of psychological distress (p=0.021) than adolescents who spent 15 minutes or less per day. There were no differences in body shape between less and more active adolescents (p >0.05). CONCLUSION: Active commuting to secondary school for more of 15 minutes per day is recommended because it is associated with higher levels of happiness and well-being in adolescents.

Quercetin supplementation does not enhance cerebellar mitochondrial biogenesis and oxidative status in exercised rats.

The present study tested the hypothesis that quercetin may inhibit the mitochondrial and antioxidant adaptations induced by exercise in cerebellar tissue. Thirty-five 6-week-old Wistar rats were randomly allocated into the following groups: quercetin, exercised (Q-Ex; n = 9); quercetin, sedentary (Q-Sed; n = 9); no quercetin, exercised (NQ-Ex; n = 9); and no quercetin, sedentary (NQ-Sed; n = 8). After 6 weeks of quercetin supplementation and/or exercise training, cerebellums were collected. Protein carbonyl content (PCC), sirtuin 1, peroxisome proliferator-activated receptor γ coactivator 1α (PGC-1α), messenger RNA levels, citrate synthase (CS), and mitochondrial DNA were measured. When Q-Sed was compared with NQ-Sed, PCC (P < .005) showed decreased levels, whereas PGC-1α, sirtuin 1 (both, P < .01), mitochondrial DNA (P < .001), and CS (P < .01) increased. However, when Q-Ex was compared with Q-Sed, PCC showed increased levels (P < .001), whereas CS decreased (P < .01). Furthermore, the NQ-Ex group experienced an increase in PGC-1α messenger RNA levels in comparison with NQ-Sed (P > .01). This effect, however, did not appear in Q-Ex (P < .05). Therefore, we must hypothesize that either the dose (25 mg/kg) or the length of the quercetin supplementation period that was used in the present study (or perhaps both) may impair exercise-induced adaptations in cerebellar tissue.

Relationship of physical activity and sedentarism with tobacco and alcohol consumption, and Mediterranean diet in Spanish teenagers / Relación de actividad física y sedentarismo con el consumo de tabaco y alcohol y dieta mediterránea en adolescentes españoles

Background and objectives: This study examined the association of physical activity and sedentarism with tobacco and alcohol consumption, and adherence to the Mediterranean diet in teenagers of both genders. Methods: A total number of 1897 Spanish teenagers (12-16 year-olds) took part in the present cross-sectional study. The variables were measured by means of questionnaires previously validated for these ages. Results: Physical activity was positively associated to the degree of adherence to the Mediterranean diet for both genders (ß = .144, P < .001 for boys and ß = .066, P < .05 for girls), and inversely associated to smoking for boys (ß = -.135, P = < .05, respectively) and girls (ß = -.148 and ß = -.141, both P < .01 and ß = .199, P < .001, respectively). Conclusion: results suggest that physical activity and sedentary behaviours have an important relationship with the adherence to the Mediterranean diet in teenagers. Also, higher levels of physical activity in boys can lead to reduced tobacco use, while watching TV and PC leisure can lead to increased alcohol consumption in girls (AU)

Introducción y objetivos: Este estudio examinó la asociación de la actividad física y el sedentarismo con el consumo de alcohol y tabaco, y la adherencia a la dieta mediterránea en adolescentes de ambos sexos. Métodos: Un total de 1897 adolescentes españoles (12- 16 años) participaron en el presente estudio transversal. Las variables fueron medidas mediante cuestionarios previamente validados para estas edades. Resultados: La actividad física estuvo positivamente asociada con el grado de adherencia a la dieta mediterránea en ambos sexos (ß = ,144, P < ,001 para chicos y ß = ,066, P < ,05 en chicas), e inversamente asociada con el tabaquismo en chicos (ß = -,135, P = < ,05, respectivamente) y chicas (ß = -,148 y ß = -,141, ambos P < ,01 y ß = ,199, P < ,001, respectivamente). Conclusión: Los resultados sugieren que la actividad física y el sedentarismo tienen una relación importante relación con la adherencia a la dieta mediterránea en adolescentes. Así mismo, altos niveles de actividad física en chicos puede ayudar a reducir el consume de tabaco, mientras que ver la televisión y el uso recreativo del ordenador pueden conducir a un incremento del consumo de alcohol entre las chicas (AU)
