Targeting Sedentary Behavior in Minority Populations as a Feasible Health Strategy during and beyond COVID-19: On Behalf of ACSM-EIM and HL-PIVOT Open
Increased sedentary behavior has been an unintended consequence of social and physical distancing restrictions needed to limit transmission of SARS-CoV-2, the novel coronavirus that causes COVID-19. Sedentary behavior is defined as any wak…

The impact of COVID‐19 severity on adult survivors: Is there a relationship between vascular reactivity and cardiorespiratory fitness? Open
The impact of COVID‐19 on cardiorespiratory fitness (CRF) is negative, increasing the likelihood of exertional symptoms such as fatigue and shortness of breath, and adversely affecting vascular function, impairing cardiovascular health. Th…

A culture of health promotion in healthcare: Can't pour from an empty cup Open
With chronic diseases increasingly prevalent in the United States (U.S.), healthcare providers are in a unique position to promote healthy living behaviors, such as physical activity (PA) and nutrition, to patients. However, many healthcar…

Profiling the persistent and episodic nature of long COVID symptoms and the impact on quality of life and functional status: a cohort observation study Open
The data presented here highlight the episodic and relapsing nature and should be used to help characterise long COVID disability. They can inform the development of long COVID-specific guidelines and support services that can adequately r…

Reference equations for peak oxygen uptake for treadmill cardiopulmonary exercise tests based on the NHANES lean body mass equations, a FRIEND registry study Open
Aims Cardiorespiratory fitness (CRF), measured by peak oxygen uptake (VO2peak), is a strong predictor of mortality. Despite its widespread clinical use, current reference equations for VO2peak show distorted calibration in obese individual…

The inclusion and consideration of cultural differences and health inequalities in physical activity behaviour in the UK - the impact of guidelines and initiatives Open
Despite widespread attempts from governments and leading health organisations worldwide to promote equity in healthy living medicine, the evidence suggests that attempts to curb worsening public health have been almost entirely ineffective…

The body weight-walking distance product as a superior parameter in determining the VO2 on-kinetics in coronary artery disease Open
The 6-minute walk test is frequently used to assess the functional capacity of the cardiac disease population. Nevertheless, anthropometric differences can confound or misestimate performance, which highlights the need for new parameters. …

Six-minute walk test reveals delayed oxygen uptake kinetics in ischemic cardiomyopathy Open
Although correlated to peak oxygen uptake (VO2), the six-minute walk test (6MWT) alone cannot provide precise physiological insight regarding the specific cause(s) of exercise limitations. We aimed to analyze whether 6MWT is able to proper…

Prediction of maximum oxygen uptake over time in adults: analysis from the FRIEND registry Open
Maximum oxygen uptake (V̇O2max) equations from developed countries are inaccurate for developing countries. Accordingly, we aimed to develop equations to predict treadmill V̇O2max over time based on variables other than exercise test in adul…
