New Heart Metric Reveals How Exercise Extends Lifespan
Australian researchers propose a new metric called 'heartbeat consumption,' which counts daily heartbeats like calories, to better monitor training and health. The study found athletes have lower daily heartbeats due to lower resting heart rates, but elite cyclists may consume more heartbeats during intense races, highlighting the potential for this metric to optimize training and prevent overexertion. However, further validation and research are needed before it becomes a standard feature on smartwatches.
