Background Despite the limitations in use of cycle threshold (CT) values for individual patient care, population distributions CT may be useful indicators local outbreaks. Objective We aimed to conduct an exploratory analysis potential correlations between distribution and COVID-19 dynamics, which were operationalized as percent positivity, transmission rate (Rt), hospitalization count. Methods...

Objective: There is a positive and significant relationship between severity viral load in some diseases. Studies on the SARS-CoV-2 at diagnosis of coronavirus disease-2019 (COVID-19) have yielded conflicting results. Therefore, we aimed to evaluate clinical status patients with COVID-19. Methods: Data diagnosed COVID-19 admitted our center May 01 June 31, 2020, were retrospectively reviewed. T...

PURPOSE To determine the relationship between maximum workload (W(peak)), the workload at the onset of blood lactate accumulation (W(OBLA)), the lactate threshold (W(LTlog)) and the D(max) lactate threshold, and the average power output obtained during a 90-min (W(90-min)) and a 20-min (W(20-min)) time trial (TT) in a group of well-trained cyclists. METHODS Nine male cyclists (.VO(2max) 62.7 ...

The intensity of exercise above which oxygen uptake (Vo2) does not account for all of the required energy to perform work has been associated with lactate accumulation in the blood (lactate threshold, LT) and elevated carbon dioxide output (gas exchange threshold). An increase in hydrogen ion concentration ([H+]) is approximately concurrent with elevation of blood lactate and CO2 output during ...
