RESUMEN

BACKGROUND: Practicing sports during childhood and adolescence provides benefits to cardiac autonomic modulation (CAM) at these stages of life. However, it is not known whether these benefits to CAM persist into adulthood. Therefore, the objective of this study was to analyze the association of early sports practice (sports practice in childhood and/or adolescence) with CAM in adult life, regardless of habitual moderate-to-vigorous PA. METHODS: The sample of the present study consisted of 242 adults (141 women and 101 men; age: 41.99 ± 16.24). The assessment of CAM was performed using heart rate variability indices. Sports practice in childhood and adolescence was assessed using a questionnaire. The intensity of physical activity was assessed using accelerometry. To analyze the association between previous sports practice (childhood and/or adolescence) and CAM, the Generalized Linear Model was adopted, considering CAM indices as continuous variables and early sports practice as a 3-fold factor (no sports practice; sports practice in childhood or adolescence; and sports practice in both childhood and adolescence) adjusted by sex, age, socioeconomic condition, and moderate to vigorous PA. RESULTS: Sports practice in childhood was associated with the average standard deviation of all normal RR intervals expressed in milliseconds (SDNN): ß = 5.89; 95%CI: 0.25;11.52, and the standard deviation of the long-term intervals between consecutive heartbeats (SD2): ß = 7.63; 95%CI:1.04; 14.23 indices. Sports practice in adolescence was associated in adulthood with the SD2 index: ß = 7.37; 95%CI: 0.71;14.04. Sports practice in at least one of the periods (childhood or adolescence) was significantly associated with the square root of the mean square of the differences between adjacent normal RR intervals for a period of time expressed in milliseconds (RMSSD) (ß = 8.86; 95%CI = 0.71;17.01), and the standard deviation of the instantaneous beat to beat variability (SD1) (ß = 6.21; 95%CI = 0.45;11.97). Sports practice at both stages of life was significantly associated with better SDNN (ß = 7.70; 95%CI = 1.16;14.23) and SD2 (ß = 10.18; 95%CI = 2.51;17.85). CONCLUSION: Early sports practice was associated with better CAM in adulthood, independently of the current physical activity level. Based on these findings, sports practice is encouraged from childhood and adolescence, for benefits to CAM in adult life.

RESUMEN

A prática de esportes é associada à formação acadêmica em diversos países, como forma de promover saúde e desenvolver competências pessoais e sociais. Este estudo buscou compreender como os universitários brasileiros percebem a influência das práticas esportivas no seu processo de integração à universidade e em seu desempenho acadêmico. Participaram 260 universitários, provenientes de um grupo maior de participantes de um estudo quantitativo, realizado online, que também apresentava perguntas abertas. As respostas a essas perguntas foram submetidas a uma análise temática. Os estudantes descrevem diferentes formas como a prática de esportes pode contribuir para a obtenção de uma melhor adaptação e desempenho acadêmico (integração e reconhecimento social, manejo do estresse e aprendizagem de competências transversais). Também foram enumeradas dificuldades para conciliar as atividades acadêmicas e esportivas (falta de tempo, incompatibilidade de calendários, cansaço associado à prática esportiva). A partir desses relatos, conclui-se que ainda são necessárias maiores medidas institucionais que estimulem a prática de esportes no ensino superior e que facilitem a sua conciliação com as atividades acadêmicas.

The practice of sports is associated with academic studies in several countries, as a way to promote health and develop personal and social skills. This study aimed to comprehend how brazilian college students perceive the influence of sports practices on their integration process at university and on their academic performance. Participants were 260 college students, from a larger group of participants in a quantitative online study, which also had open-ended questions. The answers to these questions were subjected to a thematic analysis. Students describe different ways in which sports can contribute to a better academic performance and integration (social integration and recognition, stress management and learning soft skills). Difficulties to concile academic and sports activities (lack of time, schedule incompatibility, fatigue associated with sports practice) were also listed. Based on these reports, it is concluded that greater institutional measures are still needed to encourage the practice of sports in higher education and to facilitate its conciliation with academic activities.

RESUMEN

BACKGROUND: The role of sociodemographic factors in the association between early sports participation (ESP) and sedentary behavior is unclear. We analyzed the association of ESP with sedentary behavior and identified the influence of sociodemographic factors in adulthood. METHODS: A sample of 264 community-dwelling adults was randomly assessed (42.6 [17.0] y old, 57.6% women). Sociodemographic factors (age, gender, and socioeconomic status) and ESP (retrospectively) were assessed by questionnaire. Sedentary behavior was measured by accelerometer and self-reported for domains identification. The association between ESP and sedentary behavior domains and sociodemographic factors was analyzed by Poisson regression and presented in prevalence ratio (PR). Sociodemographic factors were separately included as covariates to identify their role in the main association analysis. RESULTS: The ESP prevalence was 56.4% (n = 149). ESP participants included a higher proportion of men (59.7% vs 20.0%), had a lower age (36.8 [15.3] vs 50.8 [15.9]), and included a smaller proportion of individuals with low socioeconomic status (24.8% vs 43.5%) compared with those without ESP. The ESP was inversely associated with older age (PR = 0.58, P < .001 for middle aged; PR = 0.34, P < .001 for older participants), female gender (PR = 0.79, P < .001), low socioeconomic status (PR = 0.63, P = .036), and TV watching (PR = 0.67, P = .011). ESP was associated with driving (PR = 1.50, P = .028), office/paper work (PR = 1.63, P = .012), and using a cellphone (PR = 1.60, P = .009). The age was the main confounding factor of association between ESP and sedentary behavior, followed by socioeconomic status. No mediation role was identified. CONCLUSION: The ESP was associated with mentally active behavior domains and inversely associated with mentally passive sedentary behavior domains, but this association was majorly affected by sociodemographic factors, mainly by age.

RESUMEN

Abstract AIM: To compare bone mass and body composition variables between adolescents engaged in high-impact sports and adults who were sedentary during early life. METHOD: A cross-sectional study with 155 participants (64 adolescents and 91 adults) aged between 11 and 50 years old. Among the adults, history of sports was evaluated during face-to-face interviews, and information regarding the adolescents' training routines was provided by their coaches. Body composition was evaluated using Dual Energy X-Ray Absorptiometry which provided data about bone mineral density (BMD), bone mineral content (BMC), fat mass (FM), and free fat mass (FFM). RESULTS: Adults who engaged in sports practice during early life had higher values of BMC (ES-r = 0.063), FFM (ES-r = 0.391), and lower values of FM (ES-r = 0.396) than sedentary adults. Higher values of BMC (ES-r = 0.063) and BMD in lower limbs (ES-r = 0.091) were observed in active adolescents. Adolescents engaged in sports and adults who were sedentary in early life presented similar values in all bone variables, FM, and FFM. CONCLUSIONS: Sports involvement in early life is related to higher bone mass in adulthood. Adolescents engaged in sports presented similar bone mass to adults who had been sedentary in early life.

RESUMEN

Resumen Debido al aumento del sedentarismo entre los jóvenes, conocer la intención de práctica de actividad física en esta población puede ser determinante a la hora de inculcar futuros hábitos de práctica física para mejorar la salud actual y futura de los escolares. Así, el objetivo de este trabajo fue hallar un modelo predictivo de la intención de práctica de actividad física en tiempo libre a partir de la motivación, la satisfacción y la competencia. La muestra fue de 347 hombres y 411 mujeres de educación secundaria en España, con edades de entre 13 y 18 años. Se utilizó un cuestionario compuesto por el Sport Motivation Scale, Sport Satisfaction Instrument, el factor competencia de Basic Psychological Needs in Exercise Scalee Intention to partake in leisure-time physicalactivity, todos ellos adaptados a la Educación Física escolar. Se realizaron análisis factoriales confirmatorios y modelos de ecuaciones estructurales. La intención de práctica fue predicha por la competencia y ésta por la satisfacción/diversión. La motivación intrínseca se mostró como el mejor predictor de la satisfacción/diversión. Para predecir la intención de práctica física se debería potenciar la motivación intrínseca entre el alumnado de Educación Física.

Abstract In view of the rise in sedentary lifestyle amongst young people, knowledge regarding their intention to partake in physical activity can be decisive when it comes to instilling physical activity habits to improve the current and future health of school students. Therefore, the object of this study was to find a predictive model of the intention to partake in leisure- time physical activity based on motivation, satisfaction and competence. The sample consisted of 347 Spanish, male, high school students and 411 female students aged between 13 and 18 years old. We used a questionnaire made up of the Sport Motivation Scale, Sport Satisfaction Instrument, and the competence factor in the Basic Psychological Needs in Exercise Scale and Intention to Partake in Leisure-Time Physical Activity, all of them adapted to school Physical Education. We carried out confirmatory factor analyses and structural equation models. The intention to partake in leisure-time physical activity was predicted by competence and the latter by satisfaction/fun. Intrinsic motivation was revealed to be the best predictor of satisfaction/fun. Intrinsic motivation should be enhanced in order to predict an intention to partake in physical activity in Physical Education students.

RESUMEN

OBJECTIVE: To analyze the relationship among sports practice, physical education class, habitual physical activity and cardiovascular risk in adolescents. METHODS: Cross-sectional study with 120 schoolchildren (mean: 11.7±0.7 years old), with no regular use of medicines. Sports practice and physical education classes were assessed through face-to-face interview, while habitual physical activity was assessed by pedometers. Bodyweight, height and height-cephalic trunk were used to estimate maturation. The following variables were measured: body fatness, blood pressure, resting heart rate, blood flow velocity, intima-media thickness (carotid and femoral) and heart rate variability (mean between consecutive heartbeats and statistical index in the time domain that show the autonomic parasympathetic nervous system activity root-mean by the square of differences between adjacent normal R-R intervals in a time interval). Statistical treatment used Spearman correlation adjusted by sex, ethnicity, age, body fatness and maturation. RESULTS: Independently of potential confounders, sports practice was positively related to autonomic parasympathetic nervous system activity (â=0.039 [0.01; 0.76]). On the other hand, the relationship between sport practice and mean between consecutive heartbeats (â=0,031 [-0.01; 0.07]) was significantly mediated by biological maturation. CONCLUSIONS: Sport practice was related to higher heart rate variability at rest.

OBJETIVO: Analisar a relação entre prática esportiva, educação física escolar, atividade física habitual e indicadores cardiovasculares de risco em adolescentes. MÉTODOS: Estudo transversal que selecionou 120 escolares (idade média 11,7±0,7 anos), sem consumo de medicamentos. Prática esportiva fora do ambiente escolar e educação física escolar foram avaliadas por entrevista face a face, enquanto a atividade física habitual foi avaliada por pedometria. Peso corporal, estatura e altura troncocefálica foram usados para estimar a maturação biológica. Foram avaliados: gordura corporal, pressão arterial, frequência cardíaca durante o repouso, velocidade do fluxo sanguíneo, espessura mediointimal das artérias (carótida e femoral), variabilidade da frequência cardíaca (média entre batimentos cardíacos consecutivos e o índice estatístico no domínio do tempo que representa atividade do sistema nervoso autônomo parassimpático por meio da raiz quadrada da média das diferenças sucessivas ao quadrado entre intervalos R-R consecutivos). Correlação de Spearman verificou relação entre as variáveis. Relacionamentos significativos foram ajustados por: sexo, etnia, idade, gordura corporal e maturação biológica. RESULTADOS: Prática esportiva, independentemente dos ajustes, apresentou correlação positiva com atividade do sistema nervoso autônomo parassimpático (ß=0,039 [0,01; 0,76]). Por outro lado, a relação entre tal engajamento e a média entre os intervalos R-R (ß=0,031 [-0,01; 0,07]) foi mediada pela maturação biológica. CONCLUSÕES: A prática esportiva foi relacionada a uma maior variabilidade da frequência cardíaca durante o repouso.

RESUMEN

O objetivo deste estudo foi analisar a disposição de adolescentes a prática esportiva com base no paradigma bioecológico de Bronfenbrenner. O delineamento do presente estudo incluiu dois contextos (microssistemas) com características ambientais diferentes: (a) uma escola da rede pública e (b) uma escola da rede privada, ambas localizadas na região central da cidade de Florianópolis. Os resultados foram organizados de acordo com as duas variáveis do estudo: atributo pessoal (masculino ou feminino) e contexto (gestão pública ou gestão privada). Considerando os objetivos propostos neste estudo, verificou-se que para os escolares participantes da pesquisa, os principais fatores motivacionais que impulsionam a prática esportiva foram “Saúde“ e o “Condicionamento Físico”. Conclui-se que utilizar um modelo de pesquisa que leve em consideração a interação entre as características da pessoa, contexto e tempo é o mais eficaz para estudar as disposições dos adolescentes à prática esportiva.

The present study aimed to analyze the adolescent`s disposition for sports based in the bioecological paradigm of Bronfenbrenner. The design of this study include two contexts (microsystems) with different environmental characteristics: (a) public school and (b) private school, both located on downtown of Florianopolis. The results were organized according to two variables of the study: personal attributes (male or female) and context (public or private management). Considering the proposed aim in this study, it was verified for the scholars which have participated of the research, the main motivational factor that led to sport were “Health” and “Fitness”. Therewith, the conclusion is that using a research model which takes into account the interaction between characteristics of the person, the context and the time is the most efficient model to study the adolescent`s disposition for sports.

RESUMEN

A vaquejada é uma modalidade esportiva bastante difundida no Nordeste brasileiro, abrangendo de animais de raças puras a mestiços, assim, é importante a análise biométrica dos animais que participam dessa prática para definição dos parâmetros morfométricos. Sendo assim, o presente trabalho teve como objetivo analisar os parâmetros biométricos obtidos através do diâmetro torácico e comprimento corporal, a fim de estimar o índice corpóreo e o peso vivo verdadeiro de animais de vaquejada. Foram analisados 1289 animais, entre agosto de 2009 à abril de 2010, onde 70,98% eram machos e 29,02% fêmeas, não havendo diferença entre os parâmetros em relação ao sexo do animal, porém com aumento gradativo desses parâmetros quando relacionados à idade. Esses fatores, associados a sua biometria, favoreceram as raças citadas para as provas de vaquejada.

The vaquejada is a sport modality widespread in the Brazilian Northeast, ranging from pure-bred animals, to crossbred animals, so it is very important the biometric analysis of the animals involved in this practice to define the morphometric parameters. Therefore, this study aimed to analyze the biometric parameters obtained through the chest diameter and body length, through the chest diameter and body length in order to estimate the body's rate and body's weight true. 1289 animal data were analyzed, from August 2009 to April 2010, where 70.98% were males and 29.02% were females, with no difference between the parameters in relation to sex of the animal, but with gradual increase of these parameters when related to age. These factors, associated with biometrics, favors the race for running events with a cowboy.
