Efeito do pacing e do exercício prévio na performance aeróbia

The aim of this study was to analyze the influence of prior exercise on different intensity distribution strategies (pacing). The study included five male individuals, apparently healthy, aged between 18 and 25 years, and without regular practice of physical activities. The subjects were tested on different days following the protocols on a cycle ergometer: 1) a progressive ramp test, 2) three constant load tests in the intensities of 85%, 90% and 95% IVO2max to exhaustion, and 3) six tests with and without holding a prior exercise intensity of 70%  with different strategies for Even-intensity pace, ES (401 ± 70 W), which consists of an exercise at a pace and / or constant intensity from beginning to end; where intensity is initially increased to 10% less than the ES progressively increase to reach 10% above the intensity of ES, and; Fast-start; FS, where there is a reversal in the way of distributing intensity, ie the initial intensity is 10% higher than the value of ES decreased progressively to 10% below that ES. All these tests were performed in random order. The tlim with previous exercise was significantly shorter than without previous exercise at FS condition (p < 0.05). The VO2final obtained at ES condition was similar with (3243 ± 599 ml.min-1) and without (3252 ± 384 ml.min-1) previous aerobic exercise (p > 0.05). However, the VO2final obtained at FS condition was higher with (3291 ± 218 ml.min-1) than without (3097 ± 207 ml.min-1) previous aerobic exercise (p < 0.05). The heart rate was higher at ES condition with than without previous aerobic exercise (p < 0.05). There was no significant difference in this variable for FS condition with and without previous aerobic exercise (p > 0.05). It can be concluded that the results the previous exercise (70%) achieved lasting 6 minutes followed by 6 minutes of recovery appears to influence / commit ting the conditions during the pacing for this population

A recusa do fácil como experiência estética na poesia de Frederico Barbosa

This essay aims to drive the paths of Frederico Barbosa’s poetry to experience the refusal of the effortless. The dimensions of the emptiness, of the about and the nothing, are here under investigation as a style of expression that builds the structure of the poem. The utopian response to these themes could be in the deviation of the effortless by a refusal gesture of the language that mimetically works the paths of a style that refuses the easy way of making poetry itself.

Quando gestos não políticos são políticos: a tradução brasileira de Giovanni's Room, de James Baldwin, e a questão da homossexualidade

This work is part of a research project on the role of translations of African-American literature in Brazil and their relation to issues of identity, discourse and aesthetics. It analyzes the translation, by Affonso Blacheyre, of Giovanni's room (1956), by James Baldwin, which was published in 1967 in Brazil. Baldwin is revered for his role in the Civil Rights Movement, having produced works that portray the contradictions of a democratic, but, at the same time, racist society. Giovanni's room was first rejected by his publisher for addressing homosexuality. The text displayed on the book flaps of the translation praises Baldwin's "work with language", in contrast to his anti-racism in other works. The praise of aesthetics of Giovanni's room is noteworthy, in contrast with the absence of any remarks on its critique of the marginalization of homosexuality. The focus on the aesthetics of the work corresponded to characters speaking a more formal register in the translation. Discourses on identity strengthening were less apparent in the 60s in Brazil in comparison to nowadays. The emphasis on aesthetics represented a seemingly "non-political" gesture that made it less shocking in the context of military dictatorship prevalent in the country at the time.

Can geometric indices of heart rate variability predict improvement in autonomic modulation after resistance training in chronic obstructive pulmonary disease?

Chronic obstructive pulmonary disease (COPD) is associated with autonomic dysfunctions that can be evaluated through heart rate variability (HRV). Resistance training promotes improvement in autonomic modulation; however, studies that evaluate this scenario using geometric indices, which include nonlinear evaluation, thus providing more accurate information for physiological interpretation of HRV, are unknown. This study aimed to investigate the influence of resistance training on autonomic modulation, using geometric indices of HRV, and peripheral muscle strength in individuals with COPD. Fourteen volunteers with COPD were submitted to resistance training consisting of 24 sessions lasting 60 min each, with a frequency of three times a week. The intensity was determined as 60% of one maximum repetition and was progressively increased until 80% for the upper and lower limbs. The HRV and dynamometry were performed at two moments, the beginning and the end of the experimental protocol. Significant increases were observed in the RRtri (4·81 ± 1·60 versus 6·55 ± 2·69, P = 0·033), TINN (65·36 ± 35·49 versus 101·07 ± 63·34, P = 0·028), SD1 (7·48 ± 3·17 versus 11·04 ± 6·45, P = 0·038) and SD2 (22·30 ± 8·56 versus 32·92 ± 18·78, P = 0·022) indices after the resistance training. Visual analysis of the Poincare plot demonstrated greater dispersion beat-to-beat and in the long-term interval between consecutive heart beats. Regarding muscle strength, there was a significant increase in the shoulder abduction and knee flexion. In conclusion, geometric indices of HRV can predict improvement in autonomic modulation after resistance training in individuals with COPD; improvement in peripheral muscle strength in patients with COPD was also observed.
