Physical Exercise as a Resilience Factor to Mitigate COVID-Related Allostatic Overload

Abstract

<b><i>Introduction:</i></b> The long-lasting threat of COVID-19 makes it necessary to explore strategies to improve coping skills which enable us to master a balanced life in the face of adversity. <b><i>Objective:</i></b> To unravel the most challenging aspects of COVID-19 in a nonclinical adult population and identify predictors of lost balance and consequent allostatic overload (AO). We examined the role of regular, moderate-intensity formula aerobic exercise (312 meridian exercise) in preventing allostatic overload through increasing well-being. <b><i>Methods:</i></b> An online survey was conducted to measure CO­VID-related allostatic overload according to clinimetric criteria. The Psychosocial Index (PSI), Kellner’s Symptom Questionnaire (KSQ), short Depression Anxiety Stress Scales (DASS-21), Public Health Surveillance Well-Being Scale ­(PHS-WB), and Whiteley-7 were used to explore mental health characteristics. Univariate statistics logistic regression analysis and a general linear model were used. <b><i>Results:</i></b> According to 442 valid answers, 217 adults practiced physical exercise (PE) frequently (fPE, 3–5 times/every day) while 120 did it less regularly (1–2 times/week), and 105 did not exercise/practiced irregularly (controls). Restriction-related stressors were most challenging, resulting in AO in 29% (<i>n</i> = 128) of the sample. The main predictors were additional stressors (<i>p</i> = 0.005) and anxiety symptoms (<i>p</i> &#x3c; 0.001). The prevalence of AO was lower (<i>p</i> = 0.018) in the fPE group when compared to controls. KSQ distress symptoms were also lower in fPE (<i>p</i> &#x3c; 0.0001), while total well-being was increased (<i>p</i> &#x3c; 0.001) after adjusting for sex, age, and number of chronic diseases. According to the PHS-WB, both physical and mental well-being were higher (<i>p</i> = 0.003 and <i>p</i> = 0.004, respectively) in fPE. <b><i>Conclusions:</i></b> Frequent moderate exercise is associated with better mental and physical well-being and a lower prevalence of AO.
