Heart Rate Variability (HRV)
تغییرپذیری ضربان قلب / HRV
Beat-to-beat variation in cardiac intervals, used as a non-invasive marker within athlete monitoring when measured and interpreted consistently.

Definition
HRV reflects variation in the timing between successive heart beats and is influenced by autonomic regulation. In endurance athletes, trends can contribute to monitoring adaptation, but single readings are noisy and both high and low values can occur in different contexts.
Practical use
Measure under repeatable conditions and interpret rolling trends with sleep, training load, illness symptoms and subjective readiness rather than reacting to one morning value.
