Modificações introduzidas pelos treinamentos cardiopulmonar e neuromuscular nos níveis séricos basais de fatores de crescimento insulina símile i (igf-1), cortisol, autonomia funcional e qualidade de vida de mulheres idosas

Changes introduced by cardiopulmonar and neuromuscular training on basal serum insulin-like grow factor-1 (IGF-1) and cortisol levels, functional autonomy and quality of life in elderly women The aim of this study was to compare the effects of strength and aerobic training on basal serum IGF-1 and Cortisol levels, functional autonomy (FA) and quality of life (QoL) in elderly women after 12 weeks of training. The subjects were submitted the strength training (75-85% 1-RM) with weight exercises (SG; n=12; age=66.08 ± 3,37 years; BMI=26,77 ± 3,72 kg/m2), aerobic training with aquatic exercises (AG; n=13; age=68,69 ± 4,70 years; BMI=29,19 ± 2,96 kg/m2) and control group (CG; n=10; age=68,80 ± 5,41 years; BMI=29,70 ± 2,82 kg/m2). Fasting blood was analyzed to measure basal IGF-1 and cortisol levels by chemiluminescence method. The t-Student test showed increased IGF-1 in the SG (p<0.05) for intragroup comparison. The Repeated-measure ANOVA presented increased IGF-1 (p<0.05) in the SG compared to the other two groups. There were no differences in cortisol levels. All the FA tests (GDLAM autonomy protocol) presented decreased significant in the time marked in seconds to the SG. The same results were found in the AG, except in the rise from a sitting position test. The autonomy index presented significant improvements (p<0.05) in the SG related to the AG and CG and in the AG to the CG. The SG showed increased QoL (p<0.05) (by WHOQOL-Old questionnaire) in the facet 1 (sensorial functioning) and facet 5 (death and dying). Thus, the SG obtained positive changes on IGF-1 and FA levels when compared to the AG. This suggests that strength training can indicated to decrease the effects of ageing.

Tramas da (ir)racionalidade contemporânea para a composição do mito-tecno-lógico

The plot myth-techno-logic, contemporary, was developed starting from the dualism myth-reason. In this study, we deepened the alluded dualism taking as reference the historical contexts of the Renaissance and of the Enlightenment, emphasizing the discussion of the economical rationalization as conductive thread of the western development, in which we identified the game of the rational and of the irrational, for assure the superiority of the reason. In the context of that game, we analyzed the implications of the modernization, for the education, in function of the instrumental rationality, responsible for the environment of adaptation of the technological instruments to the scenery of the contemporary modernization. The new context is constituted by points of union and of ruptures among the technique, the science and the myth. Through our analysis, we noticed that the basic needs for the contemporary society were linked to the changes in the production means, for which the machine determine the rhythm of the work and the quality of the product. However, the changes in the productive processes promoted the appearance of the commercial marks that, as we see it, they represented the synthesis of the perfect harmony of the myth, of the technique, of the science and of the technology, in the conduction of the economical rationalization to the contemporary modernization. Thus, the contemporary modernization it arrives us for the economical rationalization, developed with the support of the technician-scientific knowledge and communicated by the articulations of the myth-techno-logical
