cardiovascular drift

car·di·o·vas·cu·lar drift

(kahr'dē-ō-vas'kyū-lăr drift)
The gradual time-dependent "drift" in several cardiovascular responses, most notably decreased stroke volume (with concomitant heart rate increase), during prolonged steady-rate exercise. The progressive increase in heart rate with cardiovascular drift during exercise decreases end-diastolic volume and hence stroke volume.

Lee explained that a multitude of experimental studies following a pre-exercise hypohydration protocol support the conclusion that dehydration significantly increases hyperthermia and cardiovascular drift.
Cardiovascular drift is attributed to the competition for blood flow between the working muscles and skin, as well as the decreasing plasma levels during dehydration; however, research has documented that sufficient fluid replacement attenuates cardiovascular drift (3).
Although the ambient temperature, the workload and the recovery time are not easily controlled in the field, ample fluid replacement during recovery periods should be provided to offset sweat losses, and attenuate cardiovascular drift.

The purpose of this study was to examine the role of active muscle mass on cardiovascular drift ([CV.
This phenomenon is called cardiovascular drift ([CV.
