The mechanical work of breathing (Wb) is an insightful tool used to assess respiratory mechanics during exercise. There are several different methods used to calculate the Wb, however, each approach having its own distinct advantages/disadvantages. To date, a comprehensive assessment of the differences in the components of Wb between these methods is lacking. We therefore sought to compare the values of Wb during graded exercise as determined via the four most popular methods

BACKGROUND The COVID-19 pandemic has arguably facilitated a shift toward increased sedentariness and reduced physical activity. Moreover, there is mounting evidence that mental health has also declined during the pandemic. However, it remains unknown to what extent social distancing (SD) behaviors and mental health have affected the physical activity levels of the general population. OBJECTIVE The purpose of this study was to determine the influence of SD behaviors and prevailing mental health on the odds of being physically active during the early COVID-19 pandemic response. METHODS A total of 4819 adults (2474/4819, 51.3%, female) from the US population with a median age of 46 (IQR 35-59) completed an online survey during the early pandemic response (April-June 2020). The survey included questions on adherence to 11 SD behaviors, and validated questionnaires which assessed self-reported physical activity, depression, anxiety, and mental well-being. Respondents were categorized into 2 physical activity groups: inactive (0-599 metabolic equivalent of task [MET]-minutes/week) and active (≥600 MET-minutes/week). A logistic generalized additive model (GAM) was used to determine which SD factors and mental health outcomes were associated with physical activity level. RESULTS The GAM analysis revealed that wearing a facemask in public (odds ratio [OR] 1.46, 95% CI 1.14-1.79; P=.003), limiting the use of public transport (OR 1.47, 95% CI 1.19-1.83; P=.001), and restricting travel outside the house (OR 1.56, 95% CI 1.19-2.05; P=.002) were SD behaviors associated with higher odds of being more physically active. Conversely, avoiding physical activity outside the house was associated with higher odds of being inactive (OR 0.52, 95% CI 0.46-0.63; PP CONCLUSIONS Based on the findings of our study, we suggest that future public health messaging of SD guidelines should include (1) a clear portrayal of the benefits of regular exercise on mental health; and (2) a specific focus on how to be physically active outdoors in a COVID-safe manner.

There are growing concerns that the COVID-19 pandemic has facilitated a sedentary shift in our physical activity habits. A reduction in physical activity during the pandemic may be secondary to restrictive policies implemented at the government-level, typically those policies which limit interpersonal contact; for example, physical/social distancing. It is without question that social distancing is a necessary measure to mitigate community transmission of the novel virus; however, these policies often limit the public’s opportunities to engage in physical activity. The strictest enforcement of social distancing occurs during an authority-mandated ‘lockdown’ (also known as a ‘shelter-in-place’ or ‘stay-at-home’ order). This Viewpoint focuses on the current evidence demonstrating that physical activity declines during a COVID-19 ‘lockdown’. We highlight the point that most of the available evidence stems from investigations using non-validated, self-reported measures of physical activity and discuss the caveats therewith. This Viewpoint explores whether current evidence reflects an ‘actual’ or rather a ‘perceived’ reduction in physical activity, and raises the question of whether this distinction matters in the end.

Upon a thorough review of the literature, the authors failed to find sufficient information and resources for Christian therapists conducting sex therapy. Our intent is to provide a model for self-of-the-therapist work for both therapists and their supervisors. The model includes various worksheets for self-reflection and different considerations for the Christian therapist to review. The model is rooted in the theoretical tenets of Narrative and Bowen Family Systems theories. The authors use the ideas of understanding our dominant story and lenses from Narrative theory and differentiation and taking an I-position from Bowen Family Systems theory. We begin by giving a brief history of the relationship between Christianity and sexuality, highlight the importance of self-of-the-therapist work, and explain the rationale for use of Narrative and Bowen theories. Finally, we present our model, which includes several worksheets for use in supervision or independently by the therapist.
