Using Zwifts metrics for targeted aerobic training seems like the perfect solution for cyclists looking to optimize their endurance, but can we really trust the numbers were seeing? Is it possible that Zwifts algorithms and power output calculations are actually hindering our ability to achieve truly targeted aerobic training?
Take Functional Threshold Power (FTP), for example - Zwifts estimate of our maximum sustainable power output over a certain period of time. How accurate is this estimate, really? Can we trust that a 20-minute all-out effort on a virtual ride accurately reflects our true FTP, or are we risking over- or under-training based on flawed data?
And what about Zwifts concept of Zones - are these truly effective for targeting specific physiological systems, or are they just a convenient way to organize workouts? Can we really trust that holding a steady state power output in the Tempo zone is going to elicit the desired physiological adaptations, or are there other factors at play?
Furthermore, how do we account for the differences in power output between riding on the road and riding on Zwift? Is it possible that the virtual environment is masking our true physiological responses to exercise, making it difficult to translate our Zwift workouts to real-world performance gains?
And what about the impact of Zwifts erg mode on our aerobic training? Does the ability to precisely control our power output and cadence actually hinder our ability to develop true aerobic fitness, or does it enhance it?
Its time to take a closer look at how were using Zwifts metrics and question whether were truly getting the most out of our virtual training sessions. Are we blindly following the numbers, or are we using them as a tool to inform our training decisions? Can we trust that Zwifts metrics are providing us with an accurate picture of our physiological state, or are we just chasing arbitrary numbers?
