Heart rate recovery (HRR) is one of the best metrics a fighter can track for cardio and recovery.
HRR measures how quickly your heart rate can return to rest after activity.
From a cardio standpoint this is important for recovery between rounds or after an intense exchange.
For recovery and longevity HRR is a great indicator of your ability to transition from a fight or flight state (sympathetic) to a rest and digest state (parasympathetic).
HRR is one of the first things we focus on when a martial artist joins The Fight Science Collective to make immediate improvements to their performance and recovery.
So if you’re struggling with cardio, stop running and start increasing your HRR.
If you need some help I put together a free guide.
