Item Endurance training improves heart rate on‐kinetics in women with subclinical hypothyroidism : a preliminary study.(2023) Almas, Saulo Peters; Werneck, Francisco Zacaron; Coelho, Emerson Filipino; Teixeira, Patrícia de Fátima dos Santos; Vaisman, MárioPurpose The aim of the study was to evaluate the efect of endurance training on heart rate (HR) on-kinetics in patients with subclinical hypothyroidism (SH). Methods Eighteen women were randomly assigned to trained group (TG) or control group (CG). Both groups performed three tests at 50 W in a cycle ergometer for 6 min. HR kinetics was obtained during the tests and the mean response time (MRT), which is equivalent to the time taken to reach 63% of the HR at steady state, was extracted. The TG was then sub- mitted to 12 weeks of endurance training (50 min, 3x/week, intensity between 70 and 85% of the maximum HR predicted for the age). Statistical analysis was performed by the mixed analysis of variance. Results At baseline, TG and CG were similar for TSH (7.7±3.1 vs. 6.9±3.3 mUI/L, p=0.602, respectively) and FT4 (12.31±1.51 vs. 12.20±1.89 pmol/L, p=0.889, respectively). After adjustment for body mass index and age, interactions between moment (baseline or after 12 weeks) and group (trained or control) were only signifcant for MRT (TG: 39.6±10 to 28.9±8.4 s, CG: 53.6±20.3 to 55±19.7 s, p=0.001) and physical activity level (CG: 7.3±0.7 to 8±0.9, CG: 6.8±0.8 in both moments, p=0.005). Conclusion The preliminary results suggest that 12 weeks of endurance training improve HR on-kinetics and physical activ- ity level in SH.Item 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, MárioObjective: 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.Item 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, MárioStudies 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.Item Indicadores multidimensionais do potencial esportivo de jovens basquetebolistas.(2022) Bizerra, Harrison Assis; Werneck, Francisco Zacaron; Ribeiro Júnior, Dilson Borges; Lauria, André de Assis; Almas, Saulo Peters; Miranda, Luciano; Ferreira, Renato Melo; Coelho, Emerson FilipinoObjetivo: O objetivo do estudo foi comparar o perfil antropométrico, físico-motor, psicossocial, maturacional e habilidades táticas de jovens jogadores de basquetebol masculino de um colégio militar. Métodos: A amostra foi composta por 318 escolares do sexo masculino, com idade entre 12 e 17 anos, os quais foram divididos em dois grupos: Jovens Atletas de Basquetebol (n=44) e Não Atletas (n=274). Foi aplicada uma bateria de testes para avaliação de indicadores multidimensionais do potencial esportivo. Resultados e Conclusão: Os jovens basquetebolistas apresentaram maior tamanho corporal, melhor desempenho físico-motor, melhores habilidades de coping e habilidades táticas além de possuírem maturação biológica avançada em relação aos não atletas. Estes resultados podem auxiliar os professores-treinadores no processo de formação e seleção de jovens basquetebolistas de nível escolar.Item 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 ZacaronIntrodução: 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.Item 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 BarataObjective. — 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.
