Cardiovascular drift
Cardiovascular drift is the gradual increase in heart rate (HR) observed during prolonged submaximal exercise, typically when the body is exposed to heat or thermoneutral conditions.
Diuretic
Substances that increase urine production, leading to fluid loss (e.g., caffeine, alcohol, certain medications).
Hypernatremia
A condition characterized by excessively high sodium levels in the blood due to inadequate water intake, leading to cellular dehydration.
Hypohydration
A state of insufficient or suboptimal body water content, produced by the process of dehydration.
Hyponatremia
A condition where excess water intake dilutes sodium levels in the blood, causing cells to swell.
Submaximal exercise
Submaximal exercise refers to exercise performed at an intensity below the maximum effort the body can sustain. Examples include steady-state aerobic exercise like long-distance running or cycling.
