Chemical composition and bioefficacy of Dennettia tripetala and Uvariodendron angustifolium leaves essential oils against the angoumois grain moth, Sitotroga cerealella

The purpose of the present study was determination of the effects of eight weeks enduring exercises on levels of cortisol, dehydroepiandrosterone (DHEA) and salivary DHEA to cortisol ratio, among non-athletes women. Fourteen under investigation subjects of this research were randomly divided to two groups exercise and control groups (7 persons for each group). The exercise group participated in 8 weeks progressive enduring trainings. Salivary samples were taken from the subjects of the two groups, both 48 hr before and 48 after the eight weeks trainings. Factor analysis of variance test with repeated measurements was used, to compare changes of variables in the two groups. An enduring trainings period would cause increment of relaxation levels of salivary cortisol (P=0.000) and decrease in those of salivary DHEA (P=0.005). Salivary DHEA to cortisol ratio decreased, though in an insignificant way (P=0.078). Although the eight weeks enduring trainings showed catabolic consistency in non-athletes females, but this catabolic consistency wasn’t significant. Perhaps, this insignificant catabolic consistency might turn to a significant manner, by elongating the trainings period. Therefore, longer period trainings should be designated, in future researches.
