Encuesta nacional de tendencias de fitness en España para 2017

Every year for the past 10 years, the American College of Sports Medicine (ACSM) has administered a global survey on fitness trends. This study has reproduced the methodology used by the ACSM surveys with the goal of identifying trends in the fitness sector in Spain. The opinion of 672 professionals in the fitness sector about 40 potential trends in the sector for 2017 were gathered via an online questionnaire. The results are compared and discussed with the results of the international surveys administered by the ACSM from 2007 to 2016. The results show that the trends in the fitness sector in Spain for 2017 largely dovetail with those found in the ACSM’s last international survey for 2016. Thus, 14 of the trends within the Top 20 are identical in both studies, with the top positions being “body weight training”, “high-intensity interval training” and “certified, experienced trained staff”. On the other hand, 4 trends in Spain’s Top 20 were specific to our country. Likewise, 12 of the identified trends match the Top 20 ranked trends in the past decade (2007-2016) devised based on the results of the ACSM’s international surveysDurante los últimos 10 años el Colegio Americano de Medicina del Deporte (American College of Sports Medicine, ACSM) realiza anualmente una encuesta global sobre tendencias de fitness. El presente estudio ha reproducido la metodología empleada en las encuestas de la ACSM y ha tenido como objetivo identificar tendencias en el sector del fitness en el ámbito español. La opinión de 672 profesionales del sector del fitness sobre 40 potenciales tendencias en el sector para el año 2017 se recogió mediante un cuestionario en línea. Los resultados obtenidos se comparan y discuten con los resultados de las encuestas internacionales realizadas por ACSM desde 2007 a 2016. Los resultados muestran que las tendencias en el sector del fitness en España para el año 2017 coinciden, en términos generales, con las encontradas en la última encuesta internacional de la ACSM para el año 2016. Así, 14 de ellas coinciden dentro del Top 20 en ambos estudios, destacando en los primeros lugares “el entrenamiento con peso corporal”, “el entrenamiento interválico de alta intensidad”, y “el personal formado cualificado y experimentado”. Por otro lado, 4 tendencias del Top 20 fueron tendencias específicas de nuestro país. Del mismo modo, 12 tendencias identificadas coinciden con el Top 20 del ranking de las tendencias de la última década (2007-2016) elaborado a partir de los resultados de las encuestas internacionales de la ACS

Enquesta nacional de tendències de fitnes a Espanya per al 2017

Durant els últims 10 anys el Col·legi Americà de Medicina de l’Esport (American College of Sports Medicine, ACSM) realitza anualment una enquesta global sobre tendències de fitnes. El present estudi ha reproduït la metodologia emprada en les enquestes de l’ACSM i ha tingut com a objectiu identificar tendències en el sector del fitnes en l’àmbit espanyol. L’opinió de 672 professionals del sector del fitnes sobre 40 potencials tendències en el sector per a l’any 2017 es va recollir mitjançant un qüestionari en línia. Els resultats obtinguts es comparen i discuteixen amb els resultats de les enquestes internacionals realitzades per ACSM des del 2007 al 2016. Els resultats mostren que les tendències en el sector del fitnes a Espanya per a l’any 2017 coincideixen, en termes generals, amb les oposades en l’última enquesta internacio­nal de l’ACSM per a l’any 2016. Així, 14 d’elles coincideixen dins del Top 20 en tots dos estudis, destacant en els primers llocs “l’entrenament amb pes corporal”, “l’entrenament intervàlic d’alta intensitat”, i “el personal format qualificat i experimentat”. D’altra banda, 4 tendències del Top 20 van ser tendències específiques del nostre país. De la mateixa manera, 12 tendències identificades coincideixen amb el Top 20 del rànquing de les tendències de l’última dècada (2007-2016) elaborat a partir dels resultats de les enquestes internacio­nals de l’ACSM

2019 National survey of fitness trends in Spain

En 2016 y 2017 se han realizado las primeras Encuestas Nacionales sobre Tendencias en Fitness en España, reproduciendo la metodología de las encuestas internacionales sobre tendencias globales de fitness promovidas por el Colegio Americano de Medicina del Deporte (ACSM) desde 2006. Este estudio presenta los resultados de la tercera Encuesta Nacional sobre Tendencias en Fitness para el año 2019. Su objetivo ha sido identificar las principales tendencias y su relevancia en el sector del fitness español para ese año. Se recogió la opinión de 600 profesionales del sector del fitness sobre 46 potenciales tendencias mediante un cuestionario online. Las tendencias más relevantes para 2019 en el contexto español son «personal formado, cualificado y experimentado», «entrenamiento funcional», «ejercicio y pérdida de peso», «entrenamiento personal», «entrenamiento interválico de alta intensidad», y «entrenamiento con el peso corporal». Las tendencias en el sector del fitness en España para 2019 han resultado ser muy estables con respecto a las tendencias que emergieron en el top 20 en la encuesta de 2018, con solo 2 tendencias nuevas y apenas cambios en sus posiciones en ranking. Sin embargo, las diferencias son mucho mayores cuando se comparan con el top 20 de la encuesta internacional de 2018, con 8 tendencias diferentes (un 40%). Esto indica cierta divergencia de las tendencias de fitness en nuestro país y las tendencias globales del sector, mostrando una dinámica propia en el sector españolIn 2016 and 2017 the first National Surveys on Fitness Trends was carried out in Spain reproducing the methodology of the worldwide surveys about global fitness trends endorsed by the American College of Sport Medicine (ACSM) since 2006. This study shows the findings of the third National Survey of Fitness Trends aimed at identifying the main trends in the Spanish fitness sector and their relevance in 2019. The opinion of 600 professionals in the fitness sector about 46 potential trends were gathered via an online questionnaire. The more relevant trends in the Spanish context for 2019 were «educated, certified and experienced fitness professionals», «functional training», «exercise and weight loss», «personal training», «high intensity interval training» and «body weight training». Trends in the Spanish fitness sector have been very stable in 2019 compared to those emerged in the top 20 in the 2018 survey, with only 2 new trends whereas the others remained almost unchanged in their ranking positions. However, differences were much greater when compared with the top 20 of the global survey of 2018, with 8 different trends (40%). This points to some divergences of fitness trend in our country and the global trends of the sector, showing a dynamic of its own in the Spanish secto

Correlatos de Educación Física medidos objetivamentes en adolescentes con síndrome de Down : Estudio UP & DOWN

Introduction: correlates of physical activity (PA) have not been explored in adolescents with Down syndrome (DS). Understanding correlates of PA could provide information to develop strategies to increase levels of PA in this target population. Objective: the aim of this study was to identify potential correlates of PA in adolescents with DS. Method: information about levels of PA and their potential correlates was collected in 98 adolescents with DS (63 males, aged 11-20 years) using accelerometers and proxy-reported questionnaires. Analysis of covariance and multiple linear regression analyses were conducted to examine correlates of PA. Result: our findings showed that participant’s age and socioeconomic status were associated with levels of PA as non-modifiable correlates. Also, parental support, father PA, television-viewing time with siblings and with friends were associated with levels of PA as modifiable correlates. Discussion and conclusion: both modifiable and non-modifiable factors are associated with levels of PA in adolescents with DS. Therefore, a better understanding of correlates of PA could contribute to develop strategies on PA promotion in adolescents with DS.Introducción: los correlatos de actividad física (AF) no han sido estudiados en adolescentes con síndrome de Down (SD). Entendiendo los correlatos de AF se podría aportar información para desarrollar estrategias para incrementar los niveles de AF en esta población diana. Objetivo: el objetivo de este estudio fue identificar correlatos de AF en adolescentes con SD. Métodos: la información de los niveles de AF y sus potenciales correlatos fue recogida en 98 adolescentes con SD (63 hombres, con edades comprendidas entre 11-20 años), usando acelerómetros y cuestionarios proxy-reportados. Se utilizó análisis de covarianza y análisis de regresión lineal múltiple para examinar los correlatos de AF. Resultados: nuestros resultados muestran que la edad y el estatus socioeconómico de los participantes fue asociado con niveles de AF como correlatos no modificables. Además, el apoyo de los padres, la AF del padre y el tiempo dedicado a ver la televisión con hermanos y amigos fueron asociados con niveles de AF como correlatos modificables. Discusión y conclusión: ambos factores modificables y no modificables se asocian con niveles de AF en adolescentes con SD. Por lo tanto, una mejor comprensión de los correlatos de AF podría contribuir a desarrollar estrategias de promoción de la AF en adolescentes con SD

¿Son el bajo nivel de condición física y la obesidad dos características del adolescente con síndrome de Down?

Introduction: “Obesity” is considered a feature of youth with DS but whether “low physical fitness” is also a feature is unknown. Objective: The aim of this case-control study was to compare the levels of fatness and fitness in adolescents with and without DS. Methods: Participants included 17 (5 girls) adolescents with DS aged 12-18 years and a control group of 94 (45 girls) adolescents without DS aged 12-16 years. The ALPHA health-related fitness test battery for children and adolescents was selected to assess fatness and fitness in both groups. Results: There were no differences in levels of fatness between groups (all P > 0.27). Adolescents with DS had lower levels of fitness in all the tests than adolescents without DS (all P < 0.001). Conclusion: Adolescents with DS have similar levels of fatness and lower levels of fitness than their peers without DSIntroducción: La obesidad es considerada una característica de los jóvenes con SD, sin embargo se desconoce si la “baja condición física” también lo es. Objetivo: Comparar los niveles de obesidad y condición física en adolescentes con y sin SD. Métodos: Participaron 17 adolescentes (5 niñas) con SD de 12 a 18 años y un grupo control de 94 (45 niñas) adolescentes sin SD de 12-16 años de edad. La batería de condición física ALPHA relacionada con la salud para niños y adolescentes fue seleccionada para evaluar la obesidad y la condición física en ambos grupos. Resultados: No se encontraron diferencias en los niveles de obesidad entre grupos (P > 0,27). Los adolescentes con SD tuvieron niveles más bajos de condición física en todos los test en comparación con los adolescentes sin SD (P < 0,001). Conclusión: Los adolescentes con SD tienen niveles similares de obesidad y menores de condición física que sus compañeros sin SD.The UP&DOWN study was supported by the Spanish Ministry of Economy and Competitiveness (DEP 2010-21662-C04).

Clinical and Ambulatory Gait Speed in Older Adults: Associations With Several Physical, Mental, and Cognitive Health Outcomes

Background: Although clinical gait speed may indicate health and well-being in older adults, there is a lack of studies comparing clinical tests with ambulatory gait speed with regard to several health outcomes. Objective: The objective of this study was to examine the associations of clinical gait speed, measured by the 2.44-m walk test and the ambulatory gait speed with several physical, mental, and cognitive health outcomes in older adults. Design: A cross-sectional design was used. Methods: The study population comprised 432 high-functioning, community-dwelling older adults (287 women) aged between 65 and 92 years. Clinical and ambulatory gait speeds were measured using the 2.44-m walk test and a portable gait analysis device, respectively. Multiple linear regressions were used to examine the association of clinical and ambulatory gait speeds with several health outcomes (body mass index, waist circumference, systolic and diastolic blood pressure, chronic conditions, self-rated health, exhaustion, upper- and lower-body strength, physical and mental health status, cognitive status, and self-rated cognitive status). Results: The results showed that the average gait speed for clinical and ambulatory measures cannot be directly compared. Clinical gait speed was associated with 7 health outcomes, and the ambulatory gait speed was associated with 6 health outcomes. The significant associations between measures of gait speed and the health outcomes converged in 5 of the 13 health outcomes studied; however, the strength of associations was singly different between measures. Limitations: The short monitoring time, the inability to distinguish between the ambulatory gait speed inside the home and outdoor gait speed, and the under-representative sample are limitations of the study. Conclusion: The results indicated differences in the number and strength of associations between clinical and ambulatory gait speed. Both measures have construct validity because they have been associated with physical and health outcomes; however, they may have different predictive validity. Further research should be conducted to compare their predictive validity in longitudinal design

Neck circumference and clustered cardiovascular risk factors in children and adolescents: Cross-sectional study.

OBJECTIVE: Early detection of cardiovascular disease (CVD) risk factors, such as obesity, is crucial to prevent adverse long-term effects on individuals' health. Therefore, the aims were: (1) to explore the robustness of neck circumference (NC) as a predictor of CVD and examine its association with numerous anthropometric and body composition indices and (2) to release sex and age-specific NC cut-off values to classify youths as overweight/obese. DESIGN: Cross-sectional study. SETTING: 23 primary schools and 17 secondary schools from Spain. PARTICIPANTS: 2198 students (1060 girls), grades 1-4 and 7-10. MEASURES: Pubertal development, anthropometric and body composition indices, systolic and diastolic blood pressure (SBP and DBP, respectively), cardiorespiratory fitness, blood sampling triglycerides (TG), total cholesterol (TC), high-density lipoprotein cholesterol (HDL-c), low-density lipoprotein cholesterol (LDL-c), glucose and inflammatory markers. Homoeostasis model assessment (HOMA-IR) and cluster of CVD risk factors were calculated. RESULTS: NC was negatively associated with maximum oxygen consumption (R2=0.231, P<0.001 for boys; R2=0.018, P<0.001 for girls) and adiponectin (R2=0.049, P<0.001 for boys; R2=0.036, P<0.001 for girls); and positively associated with SBP, DBP, TC/HDL-c, TG, HOMA, complement factors C-3 and C-4, leptin and clustered CVD risk factor in both sexes (R2 from 0.035 to 0.353, P<0.01 for boys; R2 from 0.024 to 0.215, P<0.001 for girls). Moreover, NC was positively associated with serum C reactive protein and LDL-c only in boys (R2 from 0.013 to 0.055, P<0.05). CONCLUSION: NC is a simple, low-cost and practical screening tool of excess of upper body obesity and CVD risk factors in children and adolescents. Paediatricians can easily use it as a screening tool for overweight/obesity in children and adolescents. For this purpose, sex and age-specific thresholds to classify children and adolescents as normal weight or overweight/obese are provided.This work was supported by the DEP 2010 21662 C04 00 (DEP 2010 21662 C04 01: DEP 2010 21662 C04 02: DEP 2010 21662 C04 03: DEP 2010 21662 C04 04) grant from the National Plan for Research: Development and Innovation (R+D+i) MICINN

Clathrin regulates lymphocyte migration by driving actin accumulation at the cellular leading edge

Lymphocyte migration, which is essential for effective immune responses, belongs to the so-called amoeboid migration. The lymphocyte migration is up to 100 times faster than between mesenchymal and epithelial cell types. Migrating lymphocytes are highly polarized in three well-defined structural and functional zones: uropod, medial zone, and leading edge (LE). The actiomyosin-dependent driving force moves forward the uropod, whereas massive actin rearrangements protruding the cell membrane are observed at the LE. These actin rearrangements resemble those observed at the immunological synapse driven by clathrin, a protein normally involved in endocytic processes. Here, we used cell lines as well as primary lymphocytes to demonstrate that clathrin and clathrin adaptors colocalize with actin at the LE of migrating lymphocytes, but not in other cellular zones that accumulate both clathrin and actin. Moreover, clathrin and clathrin adaptors, including Hrs, the clathrin adaptor for multivesicular bodies, drive local actin accumulation at the LE. Clathrin recruitment at the LE resulted necessary for a complete cell polarization and further lymphocyte migration in both 2D and 3D migration models. Therefore, clathrin, including the clathrin population associated to internal vesicles, controls lymphocyte migration by regulating actin rearrangements occurring at the LE.This work was supported by the grants from the Spanish Ministry of Science and Technology (MICINN; BFU2011-29450 to E.V.) and Ministry of Economy and Competitiveness (MINECO; SAF2014-56716-REDT and BFU2014-59585-R to E.V., SAF2011-25834 to F.S.M., SAF2014-58895-JIN to A.C.A and BFU2014-54181-P to J.L.C.), the Madrid regional government (INDISNET-S2011/BMD-2332 to F.S.M.) and the European Research Council (ERC-2011-AdG 294340-GENTRIS to F.S.M.).
