Scholarship from the Brazilian Graduate Studies Coordinating Board (CAPES). Research fellowship from the Brazilian National Research Council (CNPq; 305200/2013-5). J. Mota was supported by grants from the Portuguese Foundation for Science and Technology (FCT; SFRH/BSAB/142983/2018 and UID/DTP/00617/2019), as well as Scholarship Program of Santander Universities 2018.The objective of this study was to verify whether residential density and connectivity between streets are mediators on the association between perceived environmental factors and active commuting to school (ACS) in Brazilian adolescents. This is a cross-sectional study with a random sample of 1,130 adolescents (52.7% girls) aged between 14 to 20 years, from Porto Alegre, Rio Grande do Sul State, Brazil. Adolescents’ self-reported their usual mode of commuting to and from school using a questionnaire and the perceived environmental attributes by Neighborhood Environment Walkability Scale for Youth (NEWS-Y). Residential density and connectivity between streets were measured by gographic information systems (GIS), within 1km road network buffers around the participant’s residential address. Regression models were fitted according to mediation analyses procedures. The results showed that residential density is a mediator on the association between ACS and perceived environmental factors, including land-use mix diversity (IE = 0.114; 95%CI: 0.130, 0.311; 32% mediation), neighborhood recreation facilities (IE = 0.064;
95%CI: 0.034, 0.105; 15% mediation), and access to services (IE = 0.045; 95%CI: 0.006, 0.104; 14% mediation). Connectivity between streets did not correlate with ACS, thus it was not tested in the mediation model. In conclusion, residential density is a mediator on the relationship between perceived environmental factors and ACS.O estudo teve como objetivo verificar se a densidade
residencial e a conectividade entre ruas são mediadores
da associação entre fatores ambientais percebidos
e deslocamento ativo casa-escola (DAE) em
adolescentes brasileiros. Foi um estudo transversal
com uma amostra randomizada de 1.130 adolescentes
(52,7% do sexo feminino) entre 14 e 20 anos
de idade, de Porto Alegre, Rio Grande do Sul, Brasil.
Os adolescentes informaram seu modo de deslocamento
casa-escola (ida e volta) através de um
questionário, além dos atributos ambientais percebidos,
de acordo com a Neighborhood Environment
Walkability Scale for Youth (NEWS-Y).
A densidade residencial e a conectividade entre
ruas foram medidas por sistemas de informação
geográfica (SIG), dentro de um raio de 1km da rede
viária em torno do endereço residencial do participante.
Foram ajustados modelos de regressão de
acordo com os procedimentos para análises de mediação.
Os resultados mostraram que a densidade
residencial é um mediador da associação entre os
fatores ambientais percebidos e o DAE, inclusive
a diversidade do uso do solo (EI = 0,114; IC95%:
0,130, 0,311; 32% de mediação), infraestrutura
para atividades de lazer na vizinhança (EI =
0,064; IC95%: 0,034, 0,105; 15% de mediação) e
acesso a serviços (EI = 0,045; IC95%: 0,006, 0,104;
14% de mediação). A conectividade entre ruas não
mostrou correlação com DAE, portanto não foi
testado no modelo de mediação. Conclui-se que a
densidade residencial é um mediador da relação
entre fatores ambientais percebidos e DAE.El objetivo fue verificar si la densidad poblacional

Factores personales y ambientales asociados con el desplazamiento activo al colegio de los escolares españoles
Objetivos: Los factores personales y ambientales pueden influir en el transporte activo al colegio. Los objetivos fueron: a) examinar los patrones de los desplazamientos a la escuela entre los escolares y, b) analizar la asociación de factores personales y ambientales con el desplazamiento activo a la escuela.
Método: Los participantes fueron 745 escolares de 8,9 años (SD: 1,7), (363 niñas), de cuatro colegios en la provincia de Granada. Los escolares rellenaron un cuestionario sobre el modo de desplazamiento, factores personales y ambientales. Las diferencias en el modo de desplazamiento al colegio en función de género y edad se analizaron con Chi-cuadrado. La relación de los factores personales y ambientales con el desplazamiento activo al colegio se analizó con regresión logística binaria ajustada por género y edad.
Resultados: Un total de 57,2% de los escolares realizó el trayecto caminando, el 40,3% utilizó coche, un 1,2% moto, el 0,7% utilizó el autobús y la bicicleta un 0,6%. Hubo diferencias significativas según la edad para el desplazamiento andando y en coche (P = 0,003). Los niños que viajaban solos eran más activos que los que viajaban acompañados (10.049, 3.950 - 25.567%). Los niños que vivían cerca del colegio eran más activos que los que vivían más lejos (16.439, 5,717- 47,271%). Los niños que percibían caminos seguros eran más activos que aquellos que percibían caminos inseguros (2.365, 1,665- 3,360%).
Conclusión: Intervenciones a nivel familiar y estrategias ambientales en los caminos al colegio, podrían ser medidas eficaces para aumentar el desplazamiento activo al colegio.Universidad de Granada. Máster Universitario en Investigación de Actividad Física y Deporte

We are grateful to Ana Yara Postigo-Fuentes for her assistance with the English language
edition, who can be contracted through the University of Granada, Plan Propio de Investigación 2016, Excellence
actions: Units of Excellence, Unit of Excellence on Exercise and Health (UCEES), and by the Junta de Andalucía,
Consejería de Conocimiento, Investigación y Universidades and European Regional Development Fund (ERDF),
ref. SOMM17/6107/UGR.Background: The protective properties of high physical fitness levels on health are manifest
independently of age, sex, fatness, smoking, alcohol consumption, and other clinical factors. However,
women are less active than men, which contributes to low physical fitness and a high risk of CVD.
Thus, the objective of this study is to analyze the effect of two exercise interventions on health-related
physical fitness in sedentary employed females. Methods: A total of 98 physically inactive adult
women were randomly assigned to 3 study groups: the control group (CG) = 31, the endurance
training group based on Zumba Fitness® classes (ET; n = 39), and the concurrent training group
that had an extra muscle-strengthening workout after the Zumba Fitness® class (CnT; n = 28).
Body composition (BMI, waist circumference), motor fitness (one-leg stand test), musculoskeletal
fitness (shoulder–neck mobility, handgrip strength test, jump and reach test, and dynamic sit-up test),
and cardiorespiratory fitness (2-km test and estimated VO2 max) were assessed with the ALPHA-Fit
test battery for adults. Results: Both interventions showed a significant improvement in the majority
of health-related fitness and body composition variables/test (waist circumference: ET = −2.275 ±
0.95, p = 0.02, CnT = −2.550 ± 1.13, p = 0.03; one-stand leg test: ET = 13.532 ± 2.65, p < 0.001; CnT =
11.656 ± 2.88, p < 0.001; shoulder–neck mobility: ET = 1.757 ± 0.44, p < 0.001, CnT = 2.123 ± 0.47,
p < 0.001; handgrip test: 0.274 ± 0.08, p < 0.001, CnT = 0.352 ± 0.08, p < 0.001; dynamic sit-up: ET
= 1.769 ± 0.45, p < 0.001, CnT = −1.836 ± 0.49, p < 0.001; 2-km test time: −1.280 ± 0.25, p < 0.001,
CnT = −1.808 ± 0.28, p < 0.001; estimated VO2 max: ET = 1.306 ± 0.13, p < 0.001, CnT = 1.191 ±
0.15, p < 0.001). There were no significant differences after the intervention between the two exercise
intervention groups. Conclusions: Exercise interventions based on Zumba fitness® or Zumba fitness®
combined with an extra muscle-strengthening workout based on bodyweight training exercises are
effective strategies to improve the health-related physical fitness in sedentary women employees
Supervised exercise following bariatric surgery in morbid obese adults: CERTbased exercise study protocol of the EFIBAR randomised controlled trial
The authors acknowledge the help of the participants that are taking part in
the study. Moreover, authors appreciate the help to the hospitals, as well as
the sports center of the University of Almería, who helped with the
development of the project.The clinical datasets will be available according to the terms established in
the Clinicaltrials.gov NCT03497546, i.e., once the study ends and the main
results are published, contacting the responsible party ([email protected]).Trial registration: The trial was prospectively registered at Clinicaltrials.gov NCT03497546 on April 13, 2018.Background: There is increasing evidence of weight regain in patients after bariatric surgery (BS), generally
occurring from 12 to 24 months postoperatively. Postoperative exercise has been suggested to ad long-term
weight maintenance and to improve physical function in BS patients. However, there are a limited number of
intervention studies investigating the possible benefits of exercise in this population. The aim of the current report
is to provide a comprehensive CERT (Consensus on Exercise Reporting Template)-based description of the rationale
and details of the exercise programme implemented in the EFIBAR Study (Ejercicio FÍsico tras cirugía BARiátrica), a
randomised controlled trial investigating the effects of a 16-week supervised concurrent (aerobic and strength)
exercise intervention program on weight loss (primary outcome), body composition, cardiometabolic risk, physical
fitness, physical activity and quality of life (secondary outcomes) in patients with severe/morbid obesity following
bariatric surgery.
Methods: A total of 80 BS patients [60–80% expected women, aged 18 to 60 years, body mass index
(BMI) ≥ 40 kg/m2 or ≥ 35 kg/m2 with comorbid conditions)] will be enrolled in the EFIBAR Randomized
Control Trial (RCT). Participants allocated in the exercise group (n = 40) will undertake a 16-week supervised
concurrent (strength and aerobic) exercise programme (three sessions/week, 60 min/session), starting 7 to
14 days after surgery. The rationale of the exercise programme will be described following the CERT criteria
detailing the 16 key items. The study has been reviewed and approved by the Ethics Committee of the
Torrecárdenas University Hospital (Almería, Spain) (ref. N° 76/2016).
Discussion: The present study details the exercise programme of the EFIBAR RCT, which may serve: 1)
exercise professionals who would like to implement an evidence-based exercise programme for BS patients,
and 2) as an example of the application of the CERT criteria.This work was supported by Ministerio de Economía y Competitividad (MINECO),

Dance Fitness Classes Improve the Health-Related Quality of Life in Sedentary Women
Authors are grateful to valuable support of National University of Chimborazo, as well
as to all participants of the study. We are grateful to Ana Yara Postigo-Fuentes for her assistance with the
English language.Introduction: This study aims to analyze the effect of two dance-focused and choreographic
fitness classes on Health-Related Quality of Life (HRQoL) in sedentary worker women. Methods:
65 sedentary middle-aged worker women (38 ± 7.3 years old) completed a 16-week intervention
randomly assigned to: (1) dance fitness group based on Zumba Fitness classes (DF group, n = 25)],
(2) dance fitness + functional strength training group (DFFT group, n = 20), and (3) control group
(n = 20). HRQoL was assessed by the 36-Item Short-Form Health-Survey (SF-36), which evaluates
8 dimensions of health [General Health (GH), Physical Functioning (PF), Social Functioning (SF),
Physical Role (PR), Emotional Role (ER), Bodily Pain (BP), Vitality (V), and Mental Health (MH)]
scored from 0 (worst) to 100 (best health status). Results: The control group statistically differed
from both exercise groups in PF and PR, and from the DF group in SF and MH showing a lower
score. No statistical differences were observed between exercise groups post-intervention, except
in V. DF group showed increases in GH, PF, SF, V, PR, and MH post-intervention. Conclusions: A
16-week dance fitness intervention based on Zumba Fitness classes generates notable improvements
in a wide range of HRQoL dimensions in sedentary middle-aged worker women, especially in V, PR
and MH dimensions
Effectiveness of an active commuting school-based intervention at 6-month follow-up
Active commuting to school may provide a significant source of physical activity in youth. Previous school-based intervention studies have shown a positive effect on increasing the frequency of active commuting to school in the short-term. However, how the observed effects are after the intervention remains to be investigated. The objective of the present study was to investigate the effects of a school-based intervention on active commuting to school at 6-month follow-up
Supervised Exercise Immediately After Bariatric Surgery: the Study Protocol of the EFIBAR Randomized Controlled Trial
This work was supported by the Spanish Ministry of Economy and Competitiveness (MINECO), Plan Nacional de I+D+i calls RETOS 2016 (reference DEP2016-74926-R) and RETOS 2018 (reference RTI2018-093302-A-I00). EM-R and MAI were funded by the Spanish Ministry of Science, Innovation and Universities (FPU18/01107 and FPU17/01158, respectively). AH-M and LL-S were funded by the predoctoral fellowship program of the University of Almeria. The funding sources approved this study although they had no role in the design and will not have any role during its execution, analyses and interpretation of the data, writing manuscripts, or decision to submit for publication.Background Previous studies have investigated weight loss caused by exercise following bariatric surgery. However, in most
cases, the training programis poorly reported; the exercise type, volume, and intensity are briefly mentioned; and the sample size,
selection criteria, and follow-up time vary greatly across studies.
Purpose The EFIBAR study aims to investigate over 1 year the effects of a 16-week supervised exercise program, initiated
immediately after bariatric surgery, on weight loss (primary outcome), body composition, cardiometabolic risk, physical fitness,
and quality of life in patients with severe/extreme obesity.
Material and Methods The EFIBAR study is a parallel-group, superiority, randomized controlled trial (RCT), comprising 80
surgery patients. Half of the participants, randomly selected, perform a 16-week supervised exercise program, including both
strength and aerobic training, starting immediately after the surgery (7–14 days). For each participant, all primary and secondary
outcomes are measured at three different time points: (i) before the surgery, (ii) after the intervention (≈4 months), and (iii) 1 year
after the surgery.Spanish Ministry of Economy and Competitiveness (MINECO), Plan Nacional de I+D+i calls RETOS DEP2016-74926-R

Mode of commuting to school and its association with physical activity and sedentary habits in young Ecuadorian students
Active commuting to and from school (ACS) could help to increase daily physical activity levels in youth; however, this association remains unknown in Ecuadorian youth. Thus, the aims of this study were (1) to determine the patterns of commuting to and from school and (2) to analyze the associations between ACS, physical activity (PA), and sedentary habits in Ecuadorian youth. A total of 732 students (65.3% males), aged 10–18 years (children = 246, young adolescents = 310, older adolescents = 162) from the central region of Ecuador participated in this study. A self-report questionnaire, including the usual mode and frequency of commuting, distance from home to school (PACO-Questionnaire), and PA and sedentary habits (YAP-Questionnaire), was used. Most of the sample lived ?2 km from school; however, they were mainly passive commuters (96%). The most common mode of commuting was by car (to school = 43.4%, from school = 31.6%; p less than 0.001). Children presented significantly higher scores (0–4) in PA outside school and total PA compared with older adolescents (2.20 ± 0.97 vs. 1.97 ± 0.96; p = 0.013 and 2.30 ± 0.76 vs. 2.09 ± 0.74, p = 0.019, respectively), as well as the lowest scores in sedentary habits (1.51 ± 0.65, p less than 0.001). PA at school and total PA were positively associated with ACS (OR 3.137; 95% CI, 1.918 to 5.131; p less than 0.001, and OR 2.543; 95% CI, 1.428 to 4.527; p = 0.002, respectively). In conclusion, passive modes of transportation were the most frequently used to commute to and from school in young Ecuadorians. PA at school and total PA were positively associated with ACS. Thus, interventions at school setting could be an opportunity to improve PA levels and additionally ACS in youth from the central region of Ecuador. © 2018 by the authors.

Physical fitness, rating perceived exertion and academic performance in primary school
Existen estudios que han conseguido establecer una relación entre el rendimiento cognitivo y académico de los alumnos y sus niveles de condición física. Los objetivos de esta investigación son estudiar la correlación existente entre el nivel de condición física y la composición corporal con el rendimiento académico, así como analizar la correlación entre dichas variables y la percepción subjetiva del esfuerzo (RPE) por género en alumnos de Educación Primaria. Un total de 69 alumnos de Educación Primaria participaron en el estudio (edad= 12,33±0,47 años, 55,9% niñas y 44,1% niños). La condición física y la composición corporal se evaluaron siguiendo los test de la ALPHA Fitness test Battery para niños y adolescentes. El rendimiento académico se estudió mediante el promedio de notas de las asignaturas instrumentales de Educación Primaria. La RPE se registró en las clases de EF y actividades físicas escolares mediante el uso de la escala RPE de Borg (0-10). Se establecieron correlaciones significativas entre la RPE y el peso de los chicos (r= 0,406, p= 0.02) y las chicas (r= 0,643, p< 0.001) y también con respecto al IMC, chicos (r= 0,508, p= 0.004), chicas (r= 0,621, p< 0.001). Existió una correlación negativa significativa entre el test de la Course Navette y la RPE en el caso de los niños (r= -0,633, p< 0.001) y de las niñas (r= -0,452, p= 0.004). La RPE se correlacionó significativamente con los palieres del test de Course Navette (correlación inversa) y las variables antropométricas, como son el peso y el IMC.There are studies in which it has been possible to establish a relationship between the cognitive and academic performance of students and their levels of physical condition. The objectives of this research are to study the correlation between the physical fitness level and body composition with the academic performance, as well as to analyze the correlation between such variables and the Rating of Perceived Exertion (RPE) of elementary school students by gender. A total of 69 primary school students participated in the study (age= 12.33±0.47 years, 55.9% girls and 44,1% boys). The physical fitness and body composition were evaluated according to the ALPHA Fitness test Battery for children and adolescents. The academic performance was studied by means of the average of notes of the instrumental subjects of primary education. The RPE was recorded in PE classes and school physical activities by using the Borg RPE scale (0-10). Significant correlations were established between the RPE and the weight of the boys (r= 0,406, p= 0.02) and girls (r= 0,643, p< 0.001) and also with respect to the BMI, boys (r= 0,508, p= 0.004), girls (r= 0,621, p< 0.001). There was a significant negative correlation between the Course Navette test and the RPE in the case of boys (r= -0,633, p< 0.001) and girls (r= -0,452, p= 0.004). The RPE correlated significantly with the stages of the Course Navette test (inverse correlation) and with the body composition variables, such as weight and BMI
