Introduction:Adolescence is the period of transition between childhood and adult life, characterized by changes in physical, emotional, sexual and social development. Although during this phase most individuals are healthy, it is known that health status is related to behaviors and habits such as a healthy diet, the regular practice of physical activity and good sleep quality, which contribute to optimum physical and cognitive performance Objective: To determine some sleep characteristics of adolescents living in the city of Ribeirão Preto (SP).Methods: This was a cross-sectional descriptive study conducted at 14 schools in the city of Ribeirão Preto (SP) including adolescents aged 10 to 19 years who answered a questionnaire about sleep habits. The chi-square test was used to determine differences between genders with the aid of the EPI-INFO 7 software, with the level of significance set at p<0.05.Results: A total of 535 adolescents (65% girls) were included in the study. Of these, 47.7% studied during the morning period and 10.3% had a job and studied in the evening period. Regarding sleep duration, 242 (45%) slept less than 9 hours per night during week days and 256 (48%) during the weekends (Saturday and Sunday), Of the total number of adolescents studied, 75.5% reported that they went to bed when they felt sleepy, 90% reported delay in falling asleep, 84.3% used some type of electronic equipment before going to sleep, and 44% reported that they woke up during the night. In the morning, 70.3% needed to be awakened, and 44.7% reported a delay in waking up. During the daytime, 70% felt somnolent and 34% reported that they slept during the day. Girls reported that they felt more daytime sleepiness (71.3%) and slept more during the day (62.1%) than boys (28.7% and 37.9%, respectively), with the difference being statistically significant (p < 0.05). Conclusions:Almost half the adolescents investigated sleep less than the minimum time considered ideal. Furthermore, the most of adolescents went to the bed when they felt sleepy, used electronic devices before to sleep, had difficulties to fall asleep, need to be awake in the morning and felt sleepy during the day. A substantial proportion of adolescents studied awoke at night and slept during the day. Compared to boys, girls felt sleepy and slept during the day significantly.
Introduction: Physical inactivity has been pointed out as one of the major public health problems of the 21st century and the benefits of the regular practice of physical activity during adolescence are important for the biological process of growth and development. Objective: To analyze the prevalence of physical inactivity among adolescents enrolled in schools in the city of Ribeirão Preto (SP). Methods: From September 1 to November 30, 2013, a cross-sectional, observational and descriptive study was conducted with adolescents enrolled in 14 state schools in the city of Ribeirão Preto (SP) using the International Physical Activity Questionnaire, short version. Results: A total of 535 adolescents participated, 35% of them boys and 65% girls; 65% were 10 to 14 years old and 35% were 15 to 19 years old; 52.3% studied in the evening period and 10.3% worked part time on a daily basis. Regarding the level of physical activity, 15.5% of the boys and 24.1% of the girls were classified as sedentary (p>0.05). 60.4% of the boys performed physical activity of vigorous intensity, while 56.3% of the girls showed preference for physical activity of low or moderate intensity (p=0.03). The girls aged 15 to 19 years spent more time sitting during the week, while the girls aged 10 to 14 years were less active during the weekend. 24.2% of the girls aged 10 to 14 years who studied during the morning period and 13.7% of the boys and 18% of the girls who studied during the evening period were classified as sedentary. Conclusion: High rates of sedentary lifestyle were observed among adolescents enrolled in state (or public?) schools in Ribeirão Preto (Brazil). Girls presented higher rates of sedentary lifestyle than boys. Boys performed physical activity of vigorous intensity more frequently than girls. The older girls had higher rates of physical inactivity (hours spent in the sitting position) during the week days compared to the younger ones, while the latter spent more time in physical inactivity during the weekend.
The study showed that almost half the adolescents investigated sleep less than the minimum time considered ideal. Furthermore, most of the adolescents went to the bed when they felt sleepy, used electronic devices before falling sleep, had difficulties falling asleep, need to be awaken in the morning and felt sleepy during the day.
Título: Exergames e adaptações cardiovasculares e motora em adolescentes do sexo feminino: um estudo de intervenção. Ribeirão Preto, 2020.Esta investigação teve como objetivo analisar a contribuição de um programa de condicionamento físico com exergames (videogames ativos) sobre o controle postural e comparar a função autonômica cardiovascular entre adolescentes do sexo feminino, sendo desenvolvido entre os anos de 2017 e 2018. O grupo de estudo foi composto por adolescentes do sexo feminino sem e com sobrepeso com idades entre 10 e 16 anos residentes da cidade de Ribeirão Preto. As adolescentes foram submetidas a duas avaliações, onde foram investigados a variabilidade da frequência cardíaca (VFC) e o controle postural durante a participação no programa de condicionamento com exergames no Laboratório de Mídia Interativa e Exercício Físico da Escola de Educação Física e Esporte do campus USP-RP. Resultados obtidos para os índices de VFC para o domínio do tempo (RMSS e SDNN), apresentaram diferenças significativas entre os momentos pré e pós do programa com exergames (14,67 [5,86; 22,72]; 12,38 [4,82; 20,88]), respectivamente. Nas condições posturais BPA/AO base aberta com pés paralelos e olhos abertos (0,19 [0,05; 0,32]), BTD/AO (base semi tandem com pé direto a frente e olhos abertos) (-0,17 [-0,32; -0,01]) , BTD/OF (base semi tandem com pé direto a frente e olhos fechados) (-0,21 [-0,38; -0,04]) e BTE/OF (base semi tandem com pé esquerdo a frente e olhos fechados) (-0,2 [-0,38; -0,02]) foram encontradas diferenças entre os momentos pré e pós dos valores da ativação muscular dos músculos flexores e extensores do tornozelo. Os mesmos ajustes não foram identificados para o grupo sobrepeso. O deslocamento total do centro de pressão nas posturas BTD/AO (base semi tandem com pé direto a frente e olhos abertos) (0,19 [ 0,02; 0,36]) no grupo eutrófico (com peso adequado), e na postura BTE/OF (base semi tandem com pé esquerdo a frente e olhos fechados) (0,77 [ 0,18; 1,41]) no grupo sobrepeso, em comparações pré e pós, foram encontradas diferenças estatisticamente significativas. Concluímos que, os exergames podem contribuir para adaptações fisiológicas a níveis cardiovascular e motoras em grupos jovens.
