Dynamics of the heart rate response to sinusoidal work in humans: influence of physical activity and age.
The purpose of the present study was to define the influence of age and exercise training on the heart rate (HR) dynamic response (i.e. kinetics) to sinusoidal work. A total of 63 healthy subjects (31 men and 32 women; age range 19-69 years) underwent a three-step incremental work test, during which peak oxygen uptake (.V(O)(2peak)) was estimated by the YMCA method. Sinusoidal work varying betw...
متن کاملRespiratory Changes in Response to Cognitive Load: A Systematic Review
When people focus attention or carry out a demanding task, their breathing changes. But which parameters of respiration vary exactly and can respiration reliably be used as an index of cognitive load? These questions are addressed in the present systematic review of empirical studies investigating respiratory behavior in response to cognitive load. Most reviewed studies were restricted to time ...
متن کاملRespiratory care work assignment based on work rate instead of work load.
BACKGROUND We previously reported a new management variable, work rate, defined as work load due per hour, based on cumulative standard treatment times. We found that work rates were unachievable (ie, exceeded 1 hour of scheduled work per hour of available labor) for 75% of scheduled due times, despite presumed achievable average work load. OBJECTIVE To determine the optimal strategy for cre...
متن کاملRespiratory work in relation to cardiopulmonary bypass.
Twenty-four patients undergoing cardiopulmonary bypass have been studied and the work of respiration was measured (1) before the incision, (2) before bypass with the thorax open, (3) after bypass, and (4) after suturing of the incision. Our results indicate that moving the thoracic wall requires 10 to 14% of the respiratory work and that little change occurs as a consequence of cardiopulmonary ...
متن کاملWork load in general practice.
ALTHOUGH SEVERAL STUDIES HAVE ALREADY been made on this subject, e.g. Bradford Hill (1951), Fry and Dillane (1964), College of General Practitioners (1965), our information is far from complete, and this quantitative study in a relatively large list, outer suburban London practice may fill some of the gaps. At the same time the value to me has been to highlight the inefficiency of conventional ...
