Monitoring chronic physical stress using biomarkers, performance protocols and mathematical functions to identify physiological adaptations in rats

This study was undertaken to characterize the effects of monotonous training at lactate minimum (LM) intensity on aerobic and anaerobic performances; glycogen concentrationsin the soleus muscle, the gastrocnemius muscle and the liver; and creatine kinase (CK), free fatty acids and glucose concentrations in rats. The rats were separated into trained (n =10), baseline (n = 10) and sedentary (n=10) groups. The trained group was submitted to the following: 60 min/day, 6 day/week and intensity equivalent to LM during the 12-week training period. The training volume was reduced after four weeks according to a sigmoid function. The total CK (U/L) increased in the trained group after 12 weeks (742.0±158.5) in comparison with the baseline (319.6±40.2) and the sedentary (261.6+42.2) groups. Free fatty acids and glycogen stores (liver, soleus muscle and gastrocnemius muscle) increased after 12 weeks of monotonous training but aerobic and anaerobic performances were unchanged in relation to the sedentary group. The monotonous training at LM increased the level of energy substrates, unchanged aerobic performance, reduced anaerobic capacity and increased the serum CK concentration; however, the rats did not achieve the predicted training volume.

The independence of adaptations: the metanarrativity and metafictionality of Ian McEwan´s Atonement adapted for the cinema

Conceiving of cinematographic adaptations as being independent of their source material has come to be the standard approach for most specialists in this area. The stress on fidelity has made way for many other approaches, such as those focused on intertextuality, on the dilemma of form v. content, or on questions of genre and gender. The objective of this article is to present an overview of the principal theories which have been developed in the area as from 2000 in order to support this notion of independence, which will be exemplified by an exposition of the strategies used to adapt the metafictional and metanarrative elements in Atonement (2001) for the cinema.
