“…Ergometric PWC testing has a long tradition in occupational medicine for assessing whether a sufficiently high level of physical performance for coping with the daily work requirements is given [29]. An imbalance between physical workload and physical work capacity related to aging workers has been suggested to result in chronic overload, increasing the risk of long-term health effects [30,31].…”

The ongoing COVID-19 pandemic requires wearing face masks in many areas of our daily life; hence, the potential side effects of mask use are discussed. Therefore, the present study explores whether wearing a medical face mask (MedMask) affects physical working capacity (PWC). Secondary, the influence of a filtering facepiece mask with exhalation valve class 2 (FFP2exhal) and a cotton fabric mask (community mask) on PWC was also investigated. Furthermore, corresponding physiological and subjective responses when wearing face masks as well as a potential moderating role of subjects’ individual cardiorespiratory fitness and sex on face mask effects were analyzed. Thirty-nine subjects (20 males, 19 females) with different cardiorespiratory fitness levels participated in a standardized submaximal bicycle ergometer protocol using either a MedMask, FFP2exhal, community mask, or no mask (control) on four days, in randomized order. PWC130 and PWC150 as the mechanical load at the heart rates of 130 and 150 beats per minute were measured as well as transcutaneous carbon dioxide partial pressure, saturation of peripheral capillary oxygen, breathing frequency, blood pressure, perceived respiratory effort, and physical exhaustion. Using the MedMask did not lead to changes in PWC or physiological response compared to control. Neither appeared changes exceeding normal ranges when the FFP2exhal or community mask was worn. Perceived respiratory effort was up to one point higher (zero-to-ten Likert scale) when using face masks (p < 0.05) compared to control. Sex and cardiorespiratory fitness were not factors influencing the effects of the masks. The results of the present study provide reason to believe that wearing face masks for infection prevention during the COVID-19 pandemic does not pose relevant additional physical demands on the user although some more respiratory effort is required.

Background. Ergometric physical working capacity (PWC) testing has a long tradition in occupational medicine. PWC can be tested, using performance indicators like VO2max or the mechanical power. However, the calculated by bicycle ergometry PWC in reality reflects the reaction of the autonomic nervous system to muscle load, which, in turn, is strong, but still not absolutely complete, correlates with VO2max as a real indicator of cardiorespiratory fitness. The purpose of this study is to clarify the relationship between PWC, calculated based on the result of two-stage bicycle ergometry, and the parameters of neuro-endocrine regulation as well as sexual differences in such relationships. Materials and Methods. The object of observation were 30 women 29-76 (49,4±11,0) years and 30 men 24-69 (47,4±12,0) years without a clinical diagnosis, but with the deviations from the norm in a number of parameters of the neuro-endocrine-immune complex as a manifestation of maladaptation. For estimation of PWC a two-stage bicycle ergometry used. Parameters of EEG, HRV and adaptation hormones levels registered twice with an interval of 4 or 7 days. Results. In men, PWC correlates negatively with plasma levels of cortisol (r=-0,52) and triiodothyronine (r=-0,47), but positively with levels of calcitonin (r=0,25) and testosterone (r=0,22). The coefficient of multiple correlation R=0,705. In women, the correlation of the twice lower PWC with cortisol and calcitonin is weaker (r=-0,31 and 0,18, respectively), and is absent with testosterone and triiodothyronine, instead it was found in relation to aldosterone (r=-0,24); R=0,394. The PWC regression model for men includes 6 HRV and 11 EEG parameters (R=0,846), while for women only the mode HRV (r=-0,56) and two EEG parameters (R=0,608). Conclusion. PWC levels in men are generally downregulated by cortisol, triiodothyronine, sympathetic tone, and θ-rhythm generating neurons, but upregulated by testosterone, calcitonin, vagal tone, and related α-rhythm generating neurons. In women, PWC levels are borderline downregulated by cortisol and aldosterone, but significantly upregulated by circulating catecholamines and β-rhythm generating neurons.
