Cardiovascular drift (CVD, CV drift) is the phenomenon where some cardiovascular responses begin a time-dependent change, or "drift", after around 5-10 minutes of exercise in a warm or neutral environment 32 C (90 F)+ without an increase in workload. To understand the importance of fluid losses on cardiac drift researchers looked at cyclists who cycled for 2 hours either with or without taking on extra fluids during exercise.
