Basal Redox Status Influences the Adaptive Redox Response to Regular Exercise
Published in James N. Cobley, Gareth W. Davison, Oxidative Eustress in Exercise Physiology, 2022
Ethan L. Ostrom, Tinna Traustadóttir
Eustress is defined as moderate or normal physiological or environmental stress that is beneficial to the organism. Distress occurs when physiological or environmental stress is of sufficient duration or intensity to overwhelm the system and cause damage or dysfunction to the cell, tissue, organ, or organism. Acute exercise is a powerful physiologic eustress altering metabolic flux to meet the demands of the contracting skeletal muscle. Repeated application of this physiological stimulus, as in regular exercise training, leads to steady-state changes in protein content and beneficial health effects. These favorable adaptions are regulated in part by reactive oxygen species (ROS) production during the exercise bout – oxidative eustress. ROS accumulation initiates redox reactions with protein thiols that act as redox switches, altering protein localization, turnover, interacting partners, or enzyme activity (Nikolaidis et al., 2020; Kramer et al., 2015). Thus, an acute exercise bout can temporarily alter the vicinal milieu within a subcellular compartment to a more oxidized microenvironment leading to constructive changes in redox status, and subsequently resulting in beneficial long-term adaptations through changes in gene expression and protein content (Piantadosi and Suliman, 2006; Henriquez-Olguin et al., 2016, 2019a,b; Cobley et al., 2014, 2015) (Figure 6.1).

As defined by Hans Selye, there are two types of stress: eustress and distress.12 Eustress refers to positive stress that motivates individuals to invest more effort on improving performance.11,12 Distress, however, is associated with anxiety and decreased performance, and can have numerous detrimental consequences on medical and mental health.11,12
Point of Contact: The Concurrent Narrative
Published in Brian C. Miller, Reducing Secondary Traumatic Stress, 2021
The central thesis of this chapter is that intense experiences demand a narrative. If I label my stress reactions as preparing me to deal with an intense experience, my stress will do exactly that. I will think faster, recall better, and engage more fully because of the stress. This excitement narrative activates the pre-frontal cortex/eustress/engagement pathway. Eustress is the health and performance promoting form of stress. Labeling our stress as energizing us to contend with a situation doesn’t mean it will feel good. Again, it is ineffective to mislabel our stress. But this positive label does allow us to direct our energy into contending with the situation—being focused on solving the problem rather than emotional soothing.

Mental health disorders such as depression, anxiety, and stress have enormous global economic and social consequences[1]. Despite the multifactorial nature of depression, it is a common chronic illness affecting more than 300 million individuals who experience characteristic feelings of sadness, loss of interest, and happiness, leading to poor concentration, diminished appetite, and a lack of confidence [2]. Stress (distress or eustress) is a feeling of emotional or physical tension that results from a relationship between the environment and person. Chronic distress, in particular, may influence health status negatively and reportedly affects nearly 264 million individuals, according to the WHO [3]. Anxiety, on the other hand, is characterized as persistent worries even in the absence of a stressor and may present as nervousness, restlessness, and irritability, among other physiological symptoms [4].

Perceived stress encompasses an individual’s subjective appraisal of their psychological state by weighing situational demands against their ability to cope.1,2 The source of these demands can be external when they originate from one’s social and ecological environment or it can be caused by a person’s internal perceptions.3 Stress, in its beneficial construct, is referred to as eustress,4,5 which is integral in facilitating motivation, adaptation, and optimal performance.3 The beneficial properties of eustress can be diminished when individuals lack adequate resources to meet the demands of a situation, thereby increasing their likelihood of experiencing stress in its negative construct (ie, distress) that may threaten their well-being.6 The literature has widely documented the adverse implications of stress on various behavioral,7,8 psychological,9 and physical health outcomes,10 notably amongst post-secondary students pursuing higher education.

The additive model of stress suggests that greater exposure to stress leads to distress, which includes a heightened risk of negative development as well as a decreased likelihood of positive development,11 particularly when stress is perceived as taxing, disconcerting, and harmful.17 This theory is well supported by research that shows increased exposure to stress is associated with a greater likelihood of negative adjustment among Hispanic college students, including increased depression and decreased life satisfaction.15 Theories of eustress, on the other hand, suggest stress can be a positive factor in individuals’ lives, particularly when stress exposure occurs in optimal amounts, is not chronic, and is perceived as positive.10,18 This type of stress is referred to as eustress and can act as a facilitator of adjustment outcomes. For example, one study on primarily European American college students and adults suggested that experiencing stress makes individuals more aware of others’ suffering, which is in turn related to engagement in future prosocial behavior.19 Taken together, not all stress similarly influences adjustment outcomes, and eustress might actually facilitate positive social adjustment outcomes like prosocial behavior.
