Analysis of game-related statistics which discriminate between winning and losing in Brazilian professional basketball

O objetivo deste estudo foi identificar quais estatísticas relacionadas ao jogo são capazes de discriminar as equipes vencedoras das perdedoras nos jogos do Novo Basquete Brasil, campeonato brasileiro profissional masculino, em função da fase do campeonato (temporada regular e "playoff") e das diferenças de placar (placares equilibrados e não equilibrados). A amostra consistiu nos 316 jogos disputados durante a temporada 2013/2014. As variáveis analisadas foram: arremessos de dois pontos convertidos e não convertidos, arremessos de três pontos convertidos e não convertidos, lances livres convertidos e não convertidos, rebotes defensivos e ofensivos, assistências, tocos, faltas pessoais, roubos de bola e erros. Para a divisão entre placares equilibrados e não equilibrados foi realizada a análise de "cluster" de k médias. Quando a diferença de pontuação do time vencedor pela do time perdedor ficou entre um e 15 pontos, o placar foi considerado equilibrado e quando a diferença foi de 16 a 47 pontos, o placar foi não equilibrado. A análise discriminante permitiu concluir que arremessos convertidos de três pontos e rebotes defensivos foram capazes de discriminar os vencedores nos jogos de temporada regular, seja com placar equilibrado ou não equilibrado, e nos jogos de "playoff" com o placar equilibrado. As assistências contribuíram para discriminar entre os jogos de temporada regular com placar não equilibrado, enquanto os lances livres fizeram o mesmo nos jogos de temporada regular que terminaram com placares equilibrados. Nenhuma estatística relacionada ao jogo conseguiu discriminar as equipes nos jogos de "playoff" com placares não equilibrados. Este estudo mostrou que diferentes estatísticas relacionadas ao jogo discriminam entre vencedores e perdedores, dependendo da fase do campeonato e as diferenças de placar.The aim of this study was to identify which game-related statistics are capable of discriminating between winning and losing teams from Novo Basquete Brasil games, Brazilian men's professional basketball, according to championship phase (regular season or playoff) and scoring differences (balanced games or unbalanced games). The sample used corresponded to all 316 games from the 2013/2014 season. The game-related statistics analyzed were: 2 and 3 points fi eld-goals (both successful and unsuccessful), free-throws (both successful and unsuccessful), offensive and defensive rebounds, assists, blocks, personal fouls, steals and turnovers. To split between balanced and unbalanced games, a k-means cluster analysis was performed. When scoring difference fell between 1 and 15 points, the score was balanced and when the difference was from 16 to 47 points, the score was unbalanced. The discriminant analysis allowed to conclude that successful 3 points fi eld-goals and defensive rebounds discriminated winning teams in regular season games, whatever balanced or unbalanced, and in playoff balanced games. Assists were important to discriminate teams in regular season unbalanced games, while successful free-throws discriminated winners and losers in regular season balanced games. No game-related statistics were able to discriminate the teams in playoff unbalanced games. This study showed that different game-related statistics discriminate between winning and losing teams depending on the championship phase and the scoring differences

Consumo de álcool por frequentadores de academia de ginástica

Objective As there is no information in the literature about alcohol consumption profile among sportsmen, the aim of this study was to evaluate the profile of alcohol consumption by gym goers associating with anthropometry and training intensity. Methods Were invited subjects bodybuilders for at least six months, aged between 20 and 40 years, of both sexes. Anthropometric measurements were taken and body composition. To assess alcohol consumption, we used the AUDIT questionnaire. The intensity of training was identified through a semi-structured questionnaire. Results 74.1% (n = 35) of participants reported having used alcohol. In addition, 19 volunteers (38.8%) had risk behavior for alcohol consumption (AUDIT ≥ 8). Considering the binge drinking, 32 volunteers (65.3%) consumed six or more drinks of alcohol at some time in the previous year, with no difference between sexes. Body adiposity was above the recommended values among those who reported binge drinking. There was no association between the intensity of physical training and binge drinking, nor between training intensity and risk behavior for alcohol consumption. Conclusion Most sportsmen showed drinking binge in not being associated with the intensity of training. This consumption is not consistent with your goals by attending gyms. Body adiposity was above the recommended values.Objetivo: Como não há na literatura informações sobre o perfil de consumo alcoólico entre desportistas, o objetivo deste trabalho foi avaliar o perfil de consumo alcoólico por frequentadores de academia de ginástica associando com a antropometria e a intensidade do treino. Métodos: Foram convidados a participar do estudo indivíduos praticantes de musculação, por no mínimo seis meses, com idade entre 20 e 40 anos, de ambos os sexos. Foram realizadas medidas antropométricas e de composição corporal. Para avaliação do consumo alcoólico, utilizou­se o questionário AUDIT (The Alcohol Use Disorders Identification Test). A intensidade do treino foi identificada por meio de um questionário semiestruturado. Resultados: Dos participantes, 74,1% (n = 35) disseram ter feito uso de álcool. Além disso, 19 voluntários (38,8%) apresentaram comportamento de risco para o consumo de álcool (AUDIT ≥ 8). Considerando o consumo alcoólico em binge, 32 voluntários (65,3%) consumiram seis ou mais doses de álcool em alguma ocasião no ano anterior, não havendo diferença entre os sexos. A adiposidade corporal estava acima dos valores recomendados entre os que relataram consumo em binge. Não houve associação entre a intensidade do treinamento físico e o consumo de álcool em binge, nem entre a intensidade do treinamento e o comportamento de risco para o consumo de álcool. Conclusão: A maioria dos desportistas apresentou consumo de bebidas alcoólicas no padrão binge, não sendo associado à intensidade do treinamento. Este não condiz com os seus objetivos ao frequentar academias de ginástica. A adiposidade corporal estava acima dos valores recomendados

Exercise training improves quality of life in women with subclinical hypothyroidism : a randomized clinical trial.

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.

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 ?IU/mL and FT4 = 0.96 ? 0.15 ng/dl) and 17 euthyroid women (TSH = 2.28 ? 0.84 ?IU/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

Preval?ncia de sobrepeso e obesidade em escolares de um col?gio militar.

Introdu??o: Nas ?ltimas d?cadas aumentou o n?mero de pessoas acima do peso, incluindo crian?as e adolescentes, fato que ? considerado preocupante, pois pode acarretar diversas doen?as cr?nicas, em longo prazo. Objetivo: Avaliar a preval?ncia de sobrepeso e obesidade em escolares de um col?gio militar, investigando poss?veis diferen?as entre os sexos e as faixas et?rias. M?todos: Estudo quantitativo, transversal, do qual participaram 381 escolares de um col?gio militar de Minas Gerais, de 11 a 17 anos, sendo 213 meninos e 168 meninas. Calculou-se o ?ndice de massa corporal (IMC) que foi classificado segundo o PROESP-BR. Para testar diferen?as entre os sexos, utilizou-se o teste do Qui-Quadrado (?2) e para testar a rela??o entre idade e IMC, utilizou-se a correla??o de Pearson. Signific?ncia estat?stica: p < 0,05. Resultados: Foi observado sobrepeso em 17,8% (n = 68) e de obesidade em 5,8% (n = 22) dos escolares. Houve correla??o positiva entre a idade cronol?gica e o IMC (r = 0,32; p < 0,0001). N?o houve correla??o entre estado nutricional e faixa et?ria. N?o foram observadas diferen?as significativas entre os sexos, em rela??o ao sobrepeso e ? obesidade (16,9% e 6,6% nos meninos vs. 19,0% e 4,8% nas meninas, respectivamente). Conclus?o: A preval?ncia sobrepeso e obesidade nos escolares do col?gio militar, em conjunto, foi de 23,6%, tanto nos meninos quanto nas meninas, sem diferen?a significativa entre as faixas et?rias. Essa preval?ncia foi similar ? m?dia de escolares brasileiros.Introduction: Over the past few decades, the number of overweight people, including children and adolescents has increased significantly, a fact that is considered worrying, as it can lead to several chronic diseases in the long term. Objective: To evaluate the prevalence of overweight and obesity in schoolchildren of a military college, investigating possible differences between sexes and age groups. Methods: A quantitative, cross-sectional study was carried out in which 381 students from a military school in Minas Gerais, aged 11 to 17 years, were 213 boys and 168 girls. The body mass index (BMI) was calculated according to the PROESP-BR. To test for gender differences, the Chi-square test (?2) was used and Pearson's correlation was used to test the relationship between age and BMI. Statistical significance: p <0.05. Results: Overweight was observed in 17.8% (n = 68) and obesity in 5.8% (n = 22) of the students. There was a positive correlation between chronological age and BMI (r = 0.32; p <0.0001). There was no correlation between nutritional status and age range. No significant differences were observed between genders regarding overweight and obesity (16.9% and 6.6% in boys vs. 19.0% and 4.8% in girls, respectively). Conclusion: The prevalence of overweight and obesity in the students of the military college, together, was 23.6% in both boys and girls, with no significant difference between age groups. This prevalence was like the average of Brazilian schoolchildren

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

Exercise training improves quality of life in women with subclinical hypothyroidism: a randomized clinical trial

ABSTRACT 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: 175) 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 (770 ± 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
