“…Wang, Zhou, Wang, Tian, Zheng, Liu, Mai, Wang (2009) found acute pH increase and decrease could cause oxidative stress and cooperatively activate expression of CAT and GPx mRNA of Pacific white shrimp. Stress induced by acute temperature decrease from 23 to 12 also produced oxidative stress and lipid peroxidation in L. vannamei (Qiu, Wang, Wang, Liu, & Wang, 2011). In our experiment, MDA level increased, GSH contents decreased obviously in hemolymph, as well as SOD activity, which indicated obvious oxidative stress to shrimp.…”

“…Rather, we believe that 'oxidative stress' constitutes a ubiquitous fundamental biological response to the alteration of redox homeostasis imposed by the physical stress of exercise. In support to this, oxidative stress has been reported after every possible stress employed, such as increased temperature (Lushchak and Bagnyukova, 2006); decreased temperature (Qiu et al, 2011), acidic pH and alkaline pH (Wang et al, 2009); as well as hypoxia (Sharma et al, 2011) and hyperoxia (Krnic et al, 2011). There is no doubt that although diverse stimuli induce redox homeostasis alterations and/or oxidative stress, the effects of these alterations on biological adaptations are translated differently in many (or all) cases.…”

SummaryThe central aim of this review is to address the highly multidisciplinary topic of redox biology as related to exercise using an integrative and comparative approach rather than focusing on blood, skeletal muscle or humans. An attempt is also made to redefine ʻoxidative stressʼ as well as to introduce the term ʻalterations in redox homeostasisʼ to describe changes in redox homeostasis indicating oxidative stress, reductive stress or both. The literature analysis shows that the effects of non-muscledamaging exercise and muscle-damaging exercise on redox homeostasis are completely different. Non-muscle-damaging exercise induces alterations in redox homeostasis that last a few hours post exercise, whereas muscle-damaging exercise causes alterations in redox homeostasis that may persist for and/or appear several days post exercise. Both exhaustive maximal exercise lasting only 30s and isometric exercise lasting 1-3min (the latter activating in addition a small muscle mass) induce systemic oxidative stress. With the necessary modifications, exercise is capable of inducing redox homeostasis alterations in all fluids, cells, tissues and organs studied so far, irrespective of strains and species. More importantly, ʻexercise-induced oxidative stressʼ is not an ʻoddityʼ associated with a particular type of exercise, tissue or species. Rather, oxidative stress constitutes a ubiquitous fundamental biological response to the alteration of redox homeostasis imposed by exercise. The hormesis concept could provide an interpretative framework to reconcile differences that emerge among studies in the field of exercise redox biology. Integrative and comparative approaches can help determine the interactions of key redox responses at multiple levels of biological organization.Key words: antioxidant, biomarker, eccentric, free radical, training. THE JOURNAL OF EXPERIMENTAL BIOLOGY 1616The ʻgoodʼ (antioxidants), the ʻbadʼ (reactive species) and the ʻuglyʼ (oxidative stress) 1 The distinction drawn in the section heading is schematically used to parody the popular manichaeistic view that antioxidants are considered 'useful' entities, reactive species are considered 'harmful' entities and oxidative stress is considered a 'negative' state. Certainly, the reality is much more complicated and antioxidants, reactive species and oxidative stress can serve both useful and detrimental roles, which are dependent on the biological context (within an organism), which in turn are greatly dependent on the environmental context (outside an organism). AntioxidantsAdmittedly, to define the term 'antioxidant' is a difficult task. In this paper, antioxidant is defined as any mechanism, structure and/or substance that delays, prevents or removes oxidative modifications to a target molecule (Halliwell and Gutteridge, 2007;Pamplona and Costantini, 2011). Antioxidants can be complex molecules such as the superoxide dismutases and peroxiredoxins, or simpler ones such as uric acid and glutathione (Gutteridge and Halliwell, 2010). They can be broa...

“…The stresses include those induced by temperature (Zhou et al, 2011), oxidation (Qiu et al, 2011), drugs (Hsu and Chen, 2007), handling (Aparicio-Simón et al, 2010), nitrite (Tseng and Chen, 2004), salinity, and pH (Pan et al, 2007). Salinity stress is one of the most important environmental stresses that severely limit the survival and productivity of L. vannamei.…”
