RESUMO
Objective To compare the effects of strength training with load progression after 4 weeks on sleep parameters and mental health in college students. Methods A total of 17 university students (11 women, 6 men), ranging from 18 to 21 years old, were randomized into a strength training group (STG) and a control group (CG). The Pittsburgh sleep quality index (PSQI), insomnia severity questionnaire, hospital anxiety and depression (HAD) scale, profile of mood states (POMS), and chronotype were used to evaluate the main outcomes. Training consisted of 60 minute·d -1 (2 times/week, for 4-weeks), with 3 sets of 10 to 12 repetitions, and a 1-minute rest interval between sets and exercises. Baseline and postintervention differences were analyzed using generalized estimating equations (GEE). Results After 4 weeks of ST, a significant time effect on the chronotype (ß: 1.33; p < 0.05) was observed in the STG. Additionally, there was a significant time and group effect in the reduction of tension (ß: 5.00; p < 0.05), depression (ß: 15.41; p < 0.05), anger (ß: 8.00; p < 0.05), and confusion (ß: 6.50; p < 0.05). For fatigue (ß: 2.66; p < 0.05), there was a significant time effect difference in its reduction. Vigor was meaningfully increased in the STG group (ß: -1.75; p < 0.05). Furthermore, a significant positive relationship was observed between sleep quality and anxiety (r = 0.54; p = 0.03). Finally, insomnia was positively related with an increase in confusion (r = 0.70; p = 0.04) and anxiety (r = 0.52; p = 0.04), as well as with a decrease in vigor (r = -0.71; p = 0.03). Discussion Short-term strength training for 4 weeks was effective for improving mental health, helping achieve characteristics of a positive mood profile, that is, low values for negative factors and a high value for the positive factor.
RESUMO
RESUMO A pesquisa objetivou descrever, por meio de um estudo de avaliação, o alcance do Programa Saúde na Escola (PSE) em Vitória de Santo Antão-PE, no ano de 2016. Os dados foram coletados entre outubro de 2016 e fevereiro de 2017, mediante fonte documental das Secretarias Municipal de Saúde, de Educação e da Gerência Regional de Educação. O município apresentou 52 escolas cadastradas, e 26 realizaram alguma atividade referente ao programa. As ações englobaram atividades do componente I, como, por exemplo, 'Avaliação antropométrica', 'Verificação da situação vacinal', 'Promoção e avaliação da saúde bucal'. As temáticas do componente II também foram verificadas, como 'Promoção das práticas corporais e atividade física', 'Ações de segurança alimentar e alimentação saudável', 'Promoção da saúde ambiental e desenvolvimento sustentável', com foco nas arboviroses. O quantitativo de ações na zona urbana foi superior quando comparada a área rural. Um bom número de escolas cadastradas contrastando com a baixa ativação (implementação) do PSE ou, ainda, um alcance 'muito ruim' dos estudantes permearam as respostas da pesquisa, possibilitando a solidificação de subsídios para o surgimento de questionamentos essenciais às novas intervenções nesse campo de pesquisa e fornecendo outros conhecimentos sobre o programa para o público geral.
ABSTRACT The research aimed to describe, through an evaluation study in 2016, the scope of the School Health Program (PSE) in the municipality of Vitória de Santo Antão State of Pernambuco in the Northeast region of Brasil. Data were collected between October 2016 and February 2017 using documental source from the Municipal Health and Education secretaries and the Regional Education Management. The municipality had 52 registered schools and 26 carried out some activity related to the program. The actions encompassed component I activities such as 'Anthropometric assessment', 'Verification of vaccination status', 'Oral health promotion and assessment', for example. The themes of component II were also verified such as 'Promotion of body practices and physical activity', 'Food safety and healthy eating actions', 'Promotion of Environmental Health and sustainable development', with focus on arboviruses. The number of actions in the urban area was higher when compared to the rural area. A good number of registered schools contrasting with the low activation (implementation) of the PSE, or even a 'very bad' reach of students, permeated the survey answers, enabling the solidification of subsidies of essential questions to new interventions in this research field and providing other knowledges about the program to the general public.
RESUMO
Abstract Aims: To analyze the average and individual responses of sleep quality and daytime sleepiness in adolescents after four weeks of strength training. Methods: 19 adolescents with sleep problems recruited in the Federal Institute of Pernambuco, were subject to anthropometric evaluations as well as those for body composition assessment, a 1 repetition maximum test, the sleep parameters (Pittsburgh Sleep Quality Index-PSQI and Epworth Sleepiness Scale-ESS) and were submitted to four weeks of strength-training, performed alternately by segment, two sessions per week, according to recommendations for this population. Results: A decrease in the average PSQI score was observed (10.3±3.3 vs 8.8±4.0; p=0.006), but not in ESS (p>0.05), after intervention. The individual analyses demonstrated that ~63% of adolescents experienced reductions ≥ 3 points in the PSQI and ~58% of them experienced reductions ≥ 3 points in the measure of daytime sleepiness. The prevalence of poor sleep quality and daytime sleepiness reduced from 84.2% to 68.4% and from 52.6% to 31.6%, respectively. The comparisons of high and low responders to exercise training show that adolescents who reduced ≥3 points in the score of a least one sleep parameter presented lower weight, fat mass, and fat percentage (p<0.05). Conclusion: A short-term strength-training program is able to improve global sleep quality, but not daytime sleepiness in adolescents. Furthermore, the changes after training are highly heterogeneous. Further studies are required to better understand the effects of strength training on sleep parameters of adolescents.

INTRODUÇÃO: o sono é uma função biológica fundamental para a conservação da energia e a restauração do metabolismo energético. OBJETIVO: analisar o efeito de uma sessão do treinamento de força realizada em diferentes horários sobre a qualidade do sono de adolescentes e examinar se a relação entre a melhoria da qualidade do sono e o horário da sessão de treino se altera após o ajuste para idade. MÉTODOS: participaram do estudo seis estudantes do sexo masculino moradores internos do IFPE - Campus Vitória de Santo Antão, PE, Brasil. Foram realizadas três sessões de treinamento de força em diferentes horários manhã, tarde e noite, durante 12 semanas. A escala OMINI-RES foi utilizada para percepção do esforço. A qualidade do sono foi avaliada pelo Índice de Qualidade do Sono de Pittsburgh PSQI. Ainda foram avaliadas variáveis antropométricas massa corporal, estatura, IMC e a composição corporal % gordura, massa gorda e massa magra. RESULTADOS: foram observadas diferenças entre as sessões de treino realizadas em diferentes horários e a diagnose de qualidade do sono manhã: P < 0,001; tarde: P = 0,001; noite: P = 0,047. Houve correlação entre a sessão de treino realizada pela manhã r = 0,95 e à tarde r = 0,92 e a diagnose de qualidade do sono. Utilizando o modelo de regressão linear, as sessões de treinamento de força realizadas pela manhã R2 = 0,91 e tarde R2 = 0,75 explicaram de forma significativa a melhora da qualidade do sono em adolescentes, mesmo após o controle pela idade. CONCLUSÃO: as sessões de treinamento de força realizadas pela manhã e tarde apresentaram melhor resposta de qualidade do sono de adolescentes. .
INTRODUCTION: sleep is a fundamental biological function for energy conservation and restoration of the energy metabolism. OBJECTIVE: To analyze the effect of a session of strength training performed at different times on the quality of sleep of adolescents and to examine the relationship between improving the quality of sleep and the time of the training session changes after adjusting for age. METHODS: participated in this investigation six male students internal residents of IFPE - Vitória de Santo Antão, PE, Brazil. Three strength training sessions were performed at different times morning, afternoon and evening for 12 weeks. The OMNI-RES scale was used to perceived exertion. Sleep quality was assessed using the Pittsburgh Sleep Quality Index PSQI. Anthropometric variables body weight, height, BMI and body composition %fat, fat mass and lean mass were evaluated. RESULTS: differences were observed between training sessions at different times and the diagnosis of sleep quality morning: P<0.001; afternoon: P=0.001; evening: P=0.047. There was a correlation between the training session held in the morning r=0.95 and in the afternoon r=0.92 and the diagnosis of sleep quality. Using the linear regression model, the strength training sessions held in the morning R2=0.91 and afternoon R2=0.75 explained the significantly improved quality of sleep in adolescents, even after adjusting for age. CONCLUSION: the strength training sessions in the morning and afternoon showed better response in the quality of sleep of adolescents. .
