Is it possible that the emphasis on heart rate variability as a metric for measuring endurance progress in Zone 2 is actually hindering our overall development as cyclists, by creating an over-reliance on data analysis and underemphasizing the importance of feel and intuition on the bike? It seems like every coach and training program is now touting HRV as the ultimate metric for determining whether youre adapting to your training load, but what about the riders who have been successfully training and racing for years without ever even looking at their HRV? Are they just lucky, or is there something more to endurance training than just the numbers?
Ive heard arguments that HRV is the key to unlocking optimal endurance performance, but Ive also seen riders who obsess over their HRV data to the point where theyre not even listening to their bodies anymore - theyre just chasing a number, rather than paying attention to how they actually feel. And what about the riders who have naturally high or low HRV - does that mean theyre doomed to be subpar endurance athletes, no matter how hard they train?
It seems like were getting to the point where were forgetting that endurance cycling is just as much an art as it is a science - and that sometimes, the best way to get faster and more efficient is to just get on the bike and ride, rather than staring at a spreadsheet all day. So, is HRV really the be-all and end-all of endurance training, or are we just getting caught up in the latest fad?
