    Exercise training improves quality of life in women with subclinical hypothyroidism : a randomized clinical trial.
    (2018) Werneck, Francisco Zacaron; Coelho, Emerson Filipino; Almas, Saulo Peters; Garcia, Marília Mendes do Nascimento; Bonfante, Heloina Lamha Machado; Lima, Jorge Roberto Perrout de; Vigário, Patrícia dos Santos; Mainenti, Miriam Raquel Meira; Teixeira, Patrícia de Fátima dos Santos; Vaisman, Mário
    Objective: The aim was to evaluate the quality of life (HRQoL) in women with subclinical hypothyroidism (sHT) after 16 weeks of endurance training. Subjects and methods: In the first phase, a cross-sectional study was conducted in which 22 women with sHT (median age: 41.5 (interquartile range: 17.5) years, body mass index: 26.2 (8.7) kg/m2 , thyroid stimulating hormone > 4.94 mIU/L and free thyroxine between 0.8 and 1.3 ng/dL were compared to a group of 33 euthyroid women concerned to HRQoL. In the second phase, a randomized clinical trial was conducted where only women with sHT were randomly divided into two groups: sHT-Tr (n = 10) – participants that performed an exercise program – and sHT-Sed (n = 10) – controls. Exercise training consisted of 60 minutes of aerobic activities (bike and treadmill), three times a week, for 16 weeks. The HRQoL was assessed by the SF-36 questionnaire in the early and at the end of four months. Results: Women with sHT had lower scores on functional capacity domain in relation to the euthyroid ones (77.0 ± 23.0 vs. 88.8 ± 14.6; p = 0.020). The sHT-Tr group improved functional capacity, general health, emotional aspects, mental and physical component of HRQoL after training period, while the sHT-Sed group showed no significant changes. Conclusion: After 16 weeks of aerobic exercise training, there were remarkable improvements in HRQoL in women with sHT.

    Heart rate kinetics during exercise in patients with subclinical hypothyroidism.
    (2017) Almas, Saulo Peters; Werneck, Francisco Zacaron; Coelho, Emerson Filipino; Teixeira, Patrícia de Fátima dos Santos; Vaisman, Mário
    Studies suggest that patients with subclinical hypothyroidism (SH) have sympathovagal imbalance, which could lead to a slower heart rate (HR) response in the transition from rest to exercise. Thus, the objective of this study was to investigate the behavior of the HR kinetics in patients with SH during the transition from rest to exercise. The study included 18 SH women (TSH = 6.95 ± 2.94 μIU/mL and FT4 = 0.96 ± 0.15 ng/dl) and 17 euthyroid women (TSH = 2.28 ± 0.84 μIU/mL and FT4 = 0.98 ± 0.07 ng/dl). Both groups were matched for physical activity, menopausal status and age. The HR kinetics was obtained during the course of a constant-load exercise (50 W), for 6 minutes, in a cycle ergometer, and quantified from the mean response time (MRT), which is equivalent to the time taken to reach 63% of the HR at steady-state. SH patients showed slower HR kinetics than the control group (MRT = 48.5 ± 17.6s vs. 36.0 ± 10.3s, p = 0.015, respectively). The MRT has been shown to correlate with the level of physical activity (r = -0.361; p = 0.033) and with the subjective perception of exertion at the end of the exercise (r = 0.365; p = 0.031). It is concluded that SH patients have slower HR kinetics in the transition from rest to exercise when compared with euthyroid women, this impairment being associated with lower levels of physical activity.

    Prevalência de sobrepeso e obesidade em escolares de um colégio militar.
    (2019) Fayer, Patrícia Paixão; Conrado, Maria Marta; Miranda, Luciano; Ferreira, Renato Melo; Soares, Everton Rocha; Silva, Rodrigo Pereira da; Almas, Saulo Peters; Coelho, Emerson Filipino; Werneck, Francisco Zacaron
    Introdução: Nas últimas décadas aumentou o número de pessoas acima do peso, incluindo crianças e adolescentes, fato que é considerado preocupante, pois pode acarretar diversas doenças crônicas, em longo prazo. Objetivo: Avaliar a prevalência de sobrepeso e obesidade em escolares de um colégio militar, investigando possíveis diferenças entre os sexos e as faixas etárias. Métodos: Estudo quantitativo, transversal, do qual participaram 381 escolares de um colégio militar de Minas Gerais, de 11 a 17 anos, sendo 213 meninos e 168 meninas. Calculou-se o índice de massa corporal (IMC) que foi classificado segundo o PROESP-BR. Para testar diferenças entre os sexos, utilizou-se o teste do Qui-Quadrado (2) e para testar a relação entre idade e IMC, utilizou-se a correlação de Pearson. Significância estatística: p < 0,05. Resultados: Foi observado sobrepeso em 17,8% (n = 68) e de obesidade em 5,8% (n = 22) dos escolares. Houve correlação positiva entre a idade cronológica e o IMC (r = 0,32; p < 0,0001). Não houve correlação entre estado nutricional e faixa etária. Não foram observadas diferenças significativas entre os sexos, em relação ao sobrepeso e à obesidade (16,9% e 6,6% nos meninos vs. 19,0% e 4,8% nas meninas, respectivamente). Conclusão: A prevalência sobrepeso e obesidade nos escolares do colégio militar, em conjunto, foi de 23,6%, tanto nos meninos quanto nas meninas, sem diferença significativa entre as faixas etárias. Essa prevalência foi similar à média de escolares brasileiros.

    Relative age effect in Olympic basketball athletes.
    (2016) Werneck, Francisco Zacaron; Coelho, Emerson Filipino; Oliveira, Helder Zimmermann de; Ribeiro Junior, Dilson Borges; Almas, Saulo Peters; Lima, Jorge Roberto Perrout de; Matta, Marcelo de Oliveira; Figueiredo, António José Barata
    Objective. — To investigate the relative age effect (RAE) in Olympic basketball athletes, related to sex, continent and country. Methods. — The sample was composed of 300 athletes who have competed in the London 2012 Olympic Games. Athletes’ date of birth was split into quartiles (trimester of born). For data analysis, Chi2 test was used with the level of significance set at 5%. Results. — The RAE was not observed by the analysis for sex and continent. However, the RAE was found in French athletes ( 2 = 11.333; P = 0.01), with more athletes born on the second quartile. We can conclude that the RAE is not present in Olympic basketball athletes, except on those French ones.
