The interrelation between aerobic exercise, mental well-being, stress response and epigenetics
Mental well-being is a subjective, adaptive state of mind arising from complex dynamic interactions between cognitive, emotional and psychosocial factors. Positive mental well-being may promote good physical health, occupational functioning and academic achievement. In the moderate-to-vigorous intensity of aerobic range, regular cardiorespiratory exercise of sufficient duration and frequency has the capacity to boost resources of mental energy, to improve sleep, mental alertness and social interactions, to buffer maladaptive upregulated emotional responses to psychosocial stressors, to decrease anxiety, to moderate depressive symptoms and to support or even improve cognitive functioning.
Epigenetic modification is a biological mechanism by which environmental factors influence cellular phenotype and function. Psychosocial stressors, and regular performance of aerobic exercise have opposite effects on the central nervous system, mediated at least in part through epigenetic modifications that reprogram the expression of relevant genes.
Generally, physically active persons are more resilient to stress and experience fewer depressive symptoms than do physically inactive persons; and, indeed, regular moderate to strenuous aerobic activity has a mood-enhancing effect and has been proven to mitigate negative affectivity stress responses.
The purpose of this narrative review is to discuss the mechanisms that appear to play a role in aerobic exercise-induced improvement in mental well-being.https://www.oatext.com/Biomedical-Research-and-Reviews-BRR.phphj2022Periodontics and Oral Medicin
Continuity theorems for the queueing system
In this paper continuity theorems are established for the number of losses
during a busy period of the queue. We consider an queueing
system where the service time probability distribution, slightly different in a
certain sense from the exponential distribution, is approximated by that
exponential distribution. Continuity theorems are obtained in the form of one
or two-sided stochastic inequalities. The paper shows how the bounds of these
inequalities are changed if further assumptions, associated with specific
properties of the service time distribution (precisely described in the paper),
are made. Specifically, some parametric families of service time distributions
are discussed, and the paper establishes uniform estimates (given for all
possible values of the parameter) and local estimates (where the parameter is
fixed and takes only the given value). The analysis of the paper is based on
the level crossing approach and some characterization properties of the
exponential distribution.Comment: Final revision; will be published as i
