INTRODUÇÃO:Muitos trabalhos têm estudado o comportamento hormonal nos exercício resistido, entretanto poucos relacionam os hormônios cortisol, GH e insulina.OBJETIVO:Estudar os ajustes das concentrações plasmáticas dos hormônios cortisol, GH e insulina em exercícios resistidos de mesma intensidade com relação à massas musculares distintas.MÉTODOS:Dez voluntários, com 20,3 ± 4,2 anos, 74,1 ± 10,2 kg de peso, 177,2 ± 4,6 cm de estatura e 23,8 ± 3,2 kg/m2 de IMC, realizaram uma sessão de leg press (LP) e supino reto (SR) com quatro séries com 10 repetições a 70% 1 RM com três minutos de intervalo. Foram coletadas amostras de sangue para dosagem das concentrações plasmáticas de cortisol, GH e insulina em repouso (Pré) e em 0' (Rec. 0'), 30' (Rec. 30') e 90' (Rec. 90') de recuperação.RESULTADOS:As concentrações plasmáticas de cortisol foram significativamente reduzidas ao final da recuperação em LP (2,20±0,37 ng/dl para 1,33±0,38ng/dl) em relação à pré-dosagem. As concentrações de GH e insulina elevaram-se significativamente durante a recuperação. GH em LP foi significativamente maior em Rec. 0' (2,75±3,29 ng/ml para 9,60±5,32 ng/dl) do que em pré. A insulina elevou-se significativamente em Rec. 30' em LP (14,70±7,92 ulU/ml para 21,66 ± 8,61 ulU/ml) e em SR (6,17 ± 2,99 ulU/ml para 19,70 ± 13,8 ulU/ml) em relação à pré. As concentrações plasmáticas de insulina pré em LP foram significativamente superiores a SR (14,70 ulU/ml e 6,17 ± 2,99 ulU/ml).CONCLUSÃO:O exercício resistido promoveu diferentes ajustes nas concentrações hormonais de cortisol, GH e insulina durante o período de recuperação.

The objective of this study was to evaluate the quality of life (QL) of a group of menopausal women in the presence or absence of hormone replacement therapy (HRT). It consists of a cross-sectional analytical study involving women from the School Health Center - Unity Village Farmers' and Town Railway on the city of Botucatu. Participants were divided into two related groups of studies: run HRT and do not realize. We used the SF 36 and QRS, and a questionnaire to characterize the study population. No differences were seen when comparing the groups with regard to age, age at menarche and menopause. It was observed that 92% were white women and who have studied up to primary education (p = 0.0209), and those who had a partner (p = 0.0055), were the most reported changes in QL. The most frequent comorbidities were hypertension and diabetes, which is significantly more important in women without HRT. The account of the lower of QL was expressed by 28% of the sample, and the population obtained in MRS score more negative (p, 0.05). The correlation of the eight components of the SF36 and the MRS, with the presence or absence of TRH showed no significant differences. The concept of quality of life and evaluation of it is subjective and individual. However they can notice changes in QL, evidenced by instruments. One can see that menopause is not necessarily accompanied by changes in QL, however, when expressed, tend to be perceived more negatively. Despite the lower level of social and low education and women interviewed have QL as good. There is a need for studies to improve a more real relationship between HRT and QL

Adequate testosterone levels are necessary for the development, growth and maintenance of the male reproductive system. Testosterone deficiency is common in men with diabetes in whom it may contribute to impaired performance, with consequent reduction of the activity of the androgen regulated organs, such as the prostate. However, little attention has been given to the plasma dihydrotestosterone (DHT) level, the most potent androgen, nor to the expression of the androgen receptor (AR), insulin-like growth factor type I (IGF-1) and receptor (IGF-1R) in target tissues. Here, we investigated the effect of type I diabetes mellitus on DHT plasma levels and on prostate AR, IGF-1 and IGF-1R expression during rat pubertal growth. Diabetes was induced in prepubertal male rats through administration of streptozotocin (STZ; 40 mg/kg). Diabetic, diabetic treated with insulin, and age-matched control animals were killed by overdoses of pentobarbital. The ventral prostatic lobe (VP) was dissected, weighed and processed for immunohistochemistry for AR, IGF-1 e IGF-1R; plasma T and DHT levels were also determined. Hyperglycemia at puberty reduced VP weight gain to about 50% and plasma T level to about 80% of the control levels. In contrast there were no changes in plasma DHT levels. Insulin replacement restored the VP weight gain, but not the plasma T levels, which remained 90% below the ones of controls. Immunohistochemistry showed that AR, IGF-1 and IGF-1R expression in the prostate epithelial cells did not change with hyperglycemia or insulin replacement. Thus, the AR expression in the prostate epithelial cells appears to be regulated by DHT, and to a minor extent it also controls glandular growth
