There is a growing concern about the increasing decline in physical activity among adolescents. In the search for variables that may be related to physical activity, this study examined the influence of physical self-concept on objectively measured moderate-to-vigorous physical activity (MVPA) of adolescents through the mediation of the needs satisfaction and two types of autonomous motivation, for academics and for physical education. Data were collected from 618 students (301 boys and 317 girls) aged 10–14 years from 24 secondary schools in Spain. The path analysis results showed that physical self-concept positively predicted needs satisfaction and this, in turn, was positively and significantly related to the two types of autonomous motivation. Finally, only the autonomous motivation for physical education significantly and positively predicted the adolescents’ MVPA. Our findings showed that there was no evidence of an indirect effect of physical self-concept on MVPA. The results are discussed along the lines of the self-determination theory, through the analysis of the role of physical self-concept in increasing adolescents’ physical activity.

Collective Engagement

Despite evidence for the utility of self-determination theory in physical education, few studies used objective indicators of physical activity and mapped out between-class, relative to between-student, differences in physical activity. This study investigated whether moderate-to-vigorous physical activity (MVPA) and rated collective engagement in physical education were associated with autonomous motivation, controlled motivation, and amotivation at the between-class and between-student levels. Participants were 739 pupils (46.3% boys, Mage = 14.36 ± 1.94) from 46 secondary school classes in Flanders (Belgium). Multilevel analyses indicated that 37% and 63% of the variance in MVPA was explained by between-student and between-class differences, respectively. Students’ personal autonomous motivation related positively to MVPA. Average autonomous class motivation was positively related to between-class variation in MVPA and collective engagement. Average controlled class motivation and average class amotivation were negatively associated with collective engagement. The findings are discussed in light of self-determination theory’s emphasis on quality of motivation.

Practical Implications

The aim of the study was to test the associations between the self-reported access to exercise in green spaces (GS) and moderate-to-vigorous physical activity (MVPA) testing the mediating role of the motivation. Based on self-determination theory (SDT), we expected that self-determined motivation will mediate the associations between the self-reported availability of GS for exercising (GSE) and MVPA with the most self-determined exercise regulation forms (identified and intrinsic motivation) demonstrating the strongest positive associations between the variables. Method: The sample consisted of 2154 participants (74.7% women). The ages ranged from 18 to 79 years, with a mean age of 32.6 (SD = 12.2) years. Participants completed the Behavior Regulation in Exercise Questionnaire-2, the measures of self-reported distance to residential GS (RGS), availability of the GS for exercising (GSE), and physical activity (PA). Logistic regression and path analysis were used to test the associations between study variables. Results: Higher reported distance to RGS was associated with lower reported availability of GSE, but not PA. Availability of GSE was directly associated with more frequent MVPA. More autonomous forms of exercise behavior regulation (intrinsic and identified regulations) mediated the associations between self-reported availability of GSE and MVPA. Internal and identified exercise regulations were directly associated with more frequent MVPA. Conclusions: The results of the present study support the main tenets of SDT suggesting that self-determined behavioral exercise regulation is an important mediator between the self-reported availability of GSE and general MVPA. Practical implications of these findings are discussed herein.

Objective: The objective of this study was twofold. First, analyze physical activity (PA) levels during physical education (PE) with different durations (45 and 90 minutes) according to student’s obesity status. Secondly, we examine the relative contribution of 45 and 90 minutes PE (45PE and 90PE) for the compliance of the daily PA recommendations according to the body mass index (BMI). Methods: Four public schools were analyzed. The sample comprised 472 youngsters (266 girls) aged between 10 and 18 years old. PA was assessed using an Actigraph accelerometer. The participants were categorized as non-overweight (NOW) and overweight/obese (OW) according to the sex-adjusted BMI. Results: The proportion of Moderate and Vigorous Physical Activity (MVPA) was lower than the 50% recommended by guidelines regardless the PE duration. Our data showed that only 26% of NOW and 13% of OW in the 45PE achieved the recommended levels while 17% of NOW and 11% of OW achieved the recommendation in 90PE. Overall, the 90PE had a higher absolute contribution for daily MVPA recommendations compliance than 45PE. Conclusion: During PE classes youngsters spent a reduced amount of time in MVPA, independently of their weight status.Resumen. Objetivo: Este estudio tiene un doble objetivo. En primero lugar, analizar los niveles de la actividad física durante la educación física con diferentes duraciones (45 y 90 minutos) de acuerdo con el estado de la obesidad de los alumnos. En segundo lugar, se analiza la contribución relativa de 45 y 90 minutos de la educación física para el cumplimiento de las recomendaciones diarias de actividad física según el índice de masa grasa. Métodos: cuatro escuelas públicas fueran analizadas. La muestra fue de 472 jóvenes (266 chicas) con edades entre los 10 y 18 años. La actividad física fue medida utilizando un acelerómetro Actigraph. Los participantes fueran clasificados como sin sobrepeso y con sobrepeso/obesidad de acuerdo con el índice de masa grasa ajustado al género. Resultados: La proporción de la actividad física moderada y vigorosa fue inferior al 50% recomendado por las recomendaciones independiente de la duración de la clase de educación física. Nuestros datos muestran que solo unos 26% de los niños sin sobrepeso y unos 13% de niñoss con sobrepeso/obesidad llegaron al los niveles recomendados en las clases de 45 min, mientras el 17% de los jóvenes sin sobrepeso y el 11% con sobrepeso/obesidad han logrado las recomendaciones en las clases de 90 min. En general, las clases de 90 min tienen una mayor contribución para cumplimiento de las recomendaciones diarias de actividad física moderada a vigorosa do que las clases de 45 min. Conclusión: Durante las clases de educación física los jóvenes tuvieran una cantidad reducida de tiempo en actividad física moderada a vigorosa, independiente de su estado de peso.

Background:Research on adolescent physical activity is mixed regarding the role of parent activity. This study tested parent encouragement, direct modeling, and perceived influence as moderators of objectively-measured (accelerometer) parent and child moderate-to-vigorous physical activity (MVPA) associations.Methods:Parent-child dyads (n = 423; mean child age = 11.33 yrs.) wore accelerometers for 7 days; parents completed surveys. Hierarchical linear regression models tested moderation using a product of constituent terms interaction.Results:Parent-reported encouragement moderated the association between parent and child MVPA (β = –.15, P = .01, ΔR2 = .02, P < .01). Among parents with lower MVPA, child MVPA was higher for children receiving high encouragement (mean = 3.06, SE = .17) vs. low (mean = 3.03, SE = .15, P = .02) and moderate encouragement (mean = 3.40, SE = .09) vs. low (P = .04).Conclusions:Physical activity promotion programs may use parent encouragement as a tool to boost child activity, but must consider other child and parent characteristics that could attenuate effects.

El objetivo del presente estudio fue examinar los niveles objetivos de actividad física durante las clases de Educación Física en adolescentes chilenos, identificando posibles diferencias según el género. En el presente estudio participaron 156 estudiantes de enseñanza básica de Chile (69 niñas y 87 varones, edad media = 13.5 ± .7 años). Se eliminaron 34 participantes por no cumplir los criterios mínimos de registro, seleccionando finalmente a 122 adolescentes. Se evaluaron los niveles objetivos de actividad física de una clase de Educación Física mediante el acelerómetro GT3X. Los resultados mostraron que ningún participante alcanzó las recomendaciones de tiempo de práctica de actividad física moderada-vigorosa del 50% durante las clases de Educación Física. La mayoría de los estudiantes (50.7% de chicos y 72.5% de chicas) acumularon menos del 10% del tiempo de clase de Educación Física en actividad física moderada-vigorosa. Los chicos presentaron mayores valores de actividad física moderada-vigorosa que las mujeres (p < .05), pero no se encontraron diferencias en el tiempo sedentario ni en la actividad física ligera (p > .05). Los adolescentes chilenos no cumplen las recomendaciones de actividad física moderada-vigorosa en clases de Educación Física. Se discuten diferentes estrategias de incremento del tiempo empleado en dicha actividad física moderada-vigorosa como medidas a considerar. Abstract. The aim of the present study was to examine objective levels of physical activity during Physical Education (PE) classes in Chilean adolescents, identifying possible differences according to gender. A sample composed of 156 Chilean adolescents (69 female and 87 male, average age = 13.5 ± .7 years) participated in this study. A total of 34 adolescents did not meet the inclusion criteria and were excluded, with 122 participants finally considered for the data analyses. Objective levels of physical activity were assessed by means of GT3X accelerometers during a PE lesson. The results showed that none of the participants reached the recommended 50% of total PE time at moderate-to-vigorous physical activity level. Most of the students (50.7% males and 72.5% females) accumulated less than 10% of the PE time at moderate-to-vigorous physical activity level. Boys showed higher values of moderate-to-vigorous physical activity than girls (p < .05); however, there were no gender differences in sedentary behavior or light physical activity time (p > .05). Chilean adolescents do not meet the moderate-to-vigorous physical activity recommendations during PE lessons. Different strategies are discussed in order to increase the time spent at moderate-to-vigorous physical activity in PE.

Abstract Background LGBTQ+ (lesbian, gay, bisexual, transgender, queer, etc.) individuals experience challenges such as discrimination and marginalization (referred to as minority stressors) that are detrimental to their mental and physical health. Specifically, proximal or internalized LGBTQ+ minority stressors may influence motivation for and willingness to participate in physical activity. Purpose To explore whether proximal LGBTQ+ minority stressors relate to the basic psychological needs—motivation—physical activity pathway, as per self-determination theory. Methods An online cross-sectional survey was completed by 778 self-identified LGBTQ+ adults. Structural equation modelling analyses were used to examine how proximal LGBTQ+ minority stressors relate to the motivational sequence. Results Findings support that proximal LGBTQ+ minority stressors are negatively associated with psychological need satisfaction within physical activity (β = −.36), which in turn is positively associated with autonomous motivation (β = .53) and reported physical activity participation (β = .32). Overall, the final model accounted for 13% of variance in need satisfaction (small effect size), 53% of variance in autonomous motivation (moderate-large effect size), and 10% of variance in moderate-to-vigorous physical activity levels (small effect size). Conclusions Future research focused on increasing LGBTQ+ participation in physical activity should investigate the effects of (a) reducing proximal LGBTQ+ minority stressors and (b) better supporting LGBTQ+ adults’ autonomy, competence, and relatedness within physical activity contexts.

Given the low levels of physical activity (PA) in adolescence, there are challenges to increasing students' PA outside of the school setting. Thus, researchers emphasize the supportive role that physical education (PE) teachers can play in PA motivation both in and out of school. The aim of the present study was to examine an expanded trans-contextual model (TCM) model for the transit of teachers' perceived support of students' autonomy in terms of contextual and situational motivation in PE to objectively measured moderate-to-vigorous physical activity (MVPA) in PE across different PE contents as well as to the motivational sequence for, and participation in, subjective MVPA during leisure time. This cross-sectional study involved 283 high school students, of whom 43.9% were boys. The autonomous support students received and other motivational factors and objective measures of MVPA in PE and subjective MVPA in leisure time were measured. The results indicate that support for autonomy was significantly and directly related to needs satisfaction (β = 0.61, p &lt; 0.001) and indirectly to autonomous motivation in PE (β = 0.19, p &lt; 0.001) and leisure time (β = 0.16, p &lt; 0.001), intention in PE (β = 0.03, p &lt; 0.05) and leisure time (β = 0.07, p &lt; 0.001), and leisure time MVPA (β = 0.04, p &lt; 0.001), although not MVPA in PE. Gender was a significant covariate for both MVPA in PE (β = −0.62, p &lt; 0.001) and MVPA in leisure time (β = −0.37, p &lt; 0.001), with higher MVPA in boys than girls. This study filled a gap in the scientific literature by demonstrating the full motivational sequence resulting in actual MVPA in PE classes. It also demonstrated that the main goal of PE of enhancing PA not only in school but also outside of school is working. The main motivator is needs satisfaction based on PE teachers' support.

Background:This study examined the associations of objectively measured physical activity in Physical Education and recess with academic performance in youth.Methods:This cross-sectional study was conducted with 1,780 participants aged 6 to 18 years (863 girls). Physical activity was objectively measured by accelerometry and was also classified according to sex- and agespecific quartiles of physical activity intensities. Academic performance was assessed through school records.Results:Physical activity in physical education (PE) and recess was not associated with academic performance (β ranging from –0.038 to –0.003; all P > .05). Youth in the lowest quartile of physical activity in PE engaged in an average of 1.40 min of moderate-to-vigorous physical activity and those in the highest quartile engaged in 21.60 min (for recess: lowest quartile, 2.20 min; highest quartile, 11.15 min). There were no differences in academic performance between quartiles of physical activity in Physical Education and recess.Conclusions:Time spent at different physical activity intensities during PE and recess does not impair academic performance in youth.

The two types of school days that are followed in China are physical education and physical exercise days. This study objectively measured the moderate-to-vigorous physical activity (MVPA) of children during the recess, lunch break, leisure time, physical education and physical exercise segments of the physical education and physical exercise days. Moreover, this research compared the gender and grade-level differences in MVPA during each segment. A total of 316 children aged 6–13 years (M = 9.28, SD = 1.87) in Grades One to Five from three elementary schools participated in this study. Accelerometers were utilised to measure the MVPA of children. The participants accumulated the most MVPA time during physical education classes, whereas the least MVPA time was recorded during lunch break. The boys were significantly more physically active than girls during recess ( F (1, 316) = 4.449, p = 0.037, η2 = 0.030), lunch break ( F (1, 316) = 4.525, p = 0.035, η2 = 0.030) and leisure time ( F (1, 316) = 4.795, p = 0.030, η2 = 0.032) on physical education days, and during recess ( F (1, 316) = 5.968, p = 0.017, η2 = 0.079) and leisure time ( F (1, 316) = 5.246, p = 0.025, η2 = 0.070) on physical exercise days. Significant grade-level differences in the MVPA time were observed during recess ( F (2, 316) = 20.209, p < 0.001, η2 = 0.219) on physical education days and during physical exercise classes ( F (2, 316) = 3.662, p = 0.031, η2 = 0.095) and recess ( F (2, 316) = 4.326, p = 0.017, η2 = 0.110) on physical exercise days. Children in Grades Two and Three engaged in the most MVPA time during the majority of segments. In conclusion, physical activity interventions during less structured or unstructured segments are recommended. Special attention should likewise be provided to girls and children in Grades One, Four and Five to increase their MVPA.
