Abstract. Every population subgroup should know the physical activity (PA) recommendations to benefit their health. The present study sought to examine the knowledge and explore the perceptions of PA recommendations for adults among Portuguese college students, by gender and fields of study. A total of 255 bachelor students (55.3% women; Mage = 21.0±2.2 years) from sport sciences, health sciences and other fields, from four colleges in Portugal, answered to an online questionnaire. College students’ answers about knowledge of PA recommendations were submitted to an inductive thematic analysis. The chi-square test was used to assess if knowledge of PA recommendations was independent of gender and fields of study. The majority of students (51.0%) assumed not knowing the PA recommendations. From those that assumed to know the PA recommendations, only 9.8% got them right, 42% overestimated, 10.7% underestimated and 37.5% did not know them for other reasons, with no differences found by gender and field of study. Overall, these students fail to identify the minutes per week and the intensity of PA dimensions of the PA recommendations. Portuguese students do not know the PA recommendations for health, including the sports and health sciences students. Implications for the development of national PA recommendations and public health campaigns to improve knowledge of college students are discussed. Resumen. Cada subgrupo de población debe conocer las recomendaciones de actividad física (AF) para beneficiar su salud. El presente estudio buscó examinar el conocimiento y explorar las percepciones de las recomendaciones de AF para adultos entre los estudiantes universitarios portugueses, por género y áreas de estudio. Un total de 255 estudiantes de licenciatura (55.3% mujeres; Medad = 21.0 ± 2.2 años) de ciencias del deporte, ciencias de la salud y otras áreas, de cuatro universidades en Portugal, respondieron a un cuestionario online. Las respuestas de los estudiantes universitarios sobre el conocimiento de las recomendaciones de AF fueron sometidas a un análisis temático inductivo. La prueba de qui-cuadrado se usó para evaluar si el conocimiento de las recomendaciones de AF era independiente del género y de las áreas de estudio. La mayoría de los estudiantes (51.0%) asumieron no conocer las recomendaciones de AF. De aquellos que supuestamente conocían las recomendaciones de AF, solo el 9.8% las acertó, el 42% se sobreestimó, el 10.7% se subestimó y el 37.5% no las conoció por otras razones, sin diferencias por género y área de estudio. En general, estos estudiantes no identifican los minutos por semana y la intensidad de las dimensiones de las recomendaciones de AF. Los estudiantes portugueses no conocen las recomendaciones de AF para la salud, incluidos los estudiantes de deportes y ciencias de la salud. Se discuten las implicaciones para el desarrollo de recomendaciones nacionales de AF y campañas de salud pública para mejorar el conocimiento de los estudiantes universitarios.
PURPOSE: The aim of this study was to determine the relationship between socio-demographic correlates and Human Development Index (HDI) with accelerometer-measured physical activity intensity in a multicenter study. METHODS: We based our analyses on the Latin American Study of Nutrition and Health adult study (ELANS), which was a coordinated, international, cross-sectional study. 2522 adults aged 18-65 (mean 38.6) years from eight Latin America countries (i.e., Argentina, Brazil, Chile, Colombia, Costa Rica, Ecuador, Peru, and Venezuela) were considered. Accelerometer-measured sedentary time, physical activity intensity (light and moderate-to-vigorous) and steps per week. Sex, age, and ethnicity were assessed as socio-demographic correlates. The HDI country information was obtained from the United Nations Development Program. Linear regression models reporting unstandardized beta coefficients and 95% confidence intervals were used. RESULTS: Participating countries were classified as high (Brazil, Colombia, Ecuador, Peru, and Venezuela, n = 1.730) and very high (Argentina, Chile, and Costa Rica, n = 792). Women had lower levels of sedentary time (β: -18.53; 95%CI: -28.16, -8.89), moderate (β: -12.62; 95%CI: -14.52, -10.73), vigorous (β: -0.74; 95%CI: -0.94, -0.54), moderate-to-vigorous physical activity (β: -13.36; 95%CI: -15.32, -11.41), and steps per week (β: -1266.48; 95%CI: -1667.83, -865.14) than men. Younger adults presented lower sedentary time (β: -0.69; 95%CI: -1.05, -0.33), moderate (β: -0.09; 95%CI: -0.17, -0.02), vigorous (β: -0.02; 95%CI: -0.03, -0.01), and moderate-to-vigorous physical activity (β: -0.11; 95%CI: -0.19, -0.04) than older adults. Mixed (β: -2853.90; 95%CI: -3703.13, -2004.68) and White/Caucasian (β: -2193.30; 95%CI: -3076.45, -1310.14) ethnicity had lower steps per week than Black ethnicity. Countries with very high HDI had higher levels of vigorous physical activity (β: 0.26; 95%CI: 0.03,0.49), but lower steps per week (-847.28; 95%CI: -1298.31, -396.26) than high HDI. CONCLUSIONS: We found relationship between socio-demographic correlates and HDI with sedentary time, physical activity intensity (mainly moderate-to-vigorous) and steps per week which can in turn guide policies to promote physical activity in the Latin America region.

The aim of this study was to analyse the relationship between students9 participation in school sports (SS) and their self-perception. A total of 2535 students (1290 boys, 1245 girls) aged ranged 10 and 18 years old participated in this study. Data was collected using a questionnaire related to students9 self-perception, more particularly questions linked with their perception of competence, elegance, healthy, physical appearance and participation in SS. To analyse if the participation in SS was different according to the variables of self-perceptions, we used the t-test. 18% of students mentioned they took part in SS. Among these participants, 82% said that they trained twice a week. On a scale of 1–5, students generally considered themselves as being elegant (M=3.4±1), fit (M=3.5±0.7) and showed they were quite satisfied with their physical appearance (3.7±1.1). Regarding their perception of health, they answered that they were healthy (M=3.1±0.1, on a scale from 1 to 4). Comparing their participation in SS according with the variables of self-perceptions, there were not significant differences in their perception of health (p=0.746), elegance (p=0.367) and physical appearance (p=0.804). Regarding perception of competence there were significant differences (p=0.007), and it is possible to conclude that those who revealed more physical abilities were those who were involved in SS. Based upon the results the participation in SS was independent of their perception of elegance, health and satisfaction with body image. However it was observed that students with higher levels of self-perception participated more than those with lower levels. This may suggest that if correctly stimulated by teachers, students9 participation in SS could increase.
Abstract Objectives: To study the reliability/stability of the Cognitive Telephone Screening Instrument (COGTEL) for the assessment of cognitive functions, and to investigate the concurrent validity (that is, the relationship between the COGTEL scores and external variables, such as level of education and MMSE results) in a pilot study of elderly persons residing in the community in the municipal regions of Apuí, Fonte Boa and Manaus (Amazonas, Brazil). Method: This pilot study included 90 elderly persons (29 men and 61 women) aged 60-85 years of age [68.2 (± 6.7)]. The COGTEL, the MMSE and socio-economic survey were applied in the form of two interviews, a week apart and under the same conditions. Results: The test-retest intraclass correlation coefficient of the COGTEL total score (and respective six subtests), MMSE and educational level ranged from acceptable to high (0.708 < R <0.946). There was a strong positive correlation between the total score of the COGTEL with the MMSE (r =0.682; p <0.001), as well as with educational level (r =0.604; p <0.001). Conclusion: This study presents preliminary evidence of the reliability/stability and concurrent validity of the COGTEL in the evaluation of cognitive functions in elderly persons residing in the community. The results of this study support the use of COGTEL as a short, reliable and valid instrument for analyzing differences in cognitive functioning in inter-individual studies with elderly persons.
People with intellectual disabilities (ID) have high rates of overweight and obesity, heart and metabolic diseases, and low motor development. These factors compromise functional independence and autonomy in activities of daily living. The objective of this study was to clarify the design and implementation of multicomponent physical exercise programs (MPEPs) and evaluate their effects on physical fitness in people with ID. A search for scientific articles in English published before 2022 was conducted using Web of Science, PubMed, Scopus, and Science Direct databases. Scientific papers describing the effects of MPEPs on physical fitness in people with ID were considered. A total of 374 articles involving people with ID were included. Positive physical fitness outcomes were found in interventions with MPEPs in its morphological components and to a lesser extent in the motor, muscular, metabolic, and cardiorespiratory aspects in people with ID. Further research is needed to standardize and elucidate the effects of the MPEP on other functional dimensions of physical fitness to use them as a physical activity alternative to reduce sedentary behavior in people with ID.
A importância atribuida a Educacao Fisica na escola justifica-se pelo papel que esta exerce sobre a formacao das novas geracoes, influenciando a aquisicao de habitos saudaveis e aprendizagens socialmente relevantes, contribuindo para o pleno e harmonioso desenvolvimento pessoal e social. Apesar de notabilizar-se como a unica disciplina capaz de promover a saude dos escolares ao ensinar estilos de vida ativos, sofre pela falta de legitimidade, nao conseguindo junto a comunidade escolar apresentar-se de forma clara com objetivos e conteudos definidos, alem da ausencia de consenso entre os professores frente as diversas concepcoes de ensino. E neste panorama e procurando contribuir com a melhoria do estatuto da Educacao Fisica na escola que o presente artigo aborda por meio dos resultados da investigacao o potencial da disciplina na promocao da saude, a relacao com a atividade fisica e com o rendimento academico dos alunos. Por fim, veremos as concepcoes de Educacao Fisica refletindo sobre a mais adequada para a promocao de estilos de vida ativos e saudaveis e que promove a atividade fisica em quantidade, qualidade e intensidade suficientes de modo a atender as recomendacoes.
