So the conventional wisdom is that fasted Zone 2 rides are a magic bullet for endurance training, but whats the real frequency for optimal benefits? Is it just a case of the more, the merrier, or are coaches and athletes just peddling a fad thats not supported by actual science?
Why do the proponents of fasted Zone 2 rides seem to think that this specific protocol is a one-size-fits-all solution for everyone from casual commuters to elite athletes? What about individual variability in insulin sensitivity, diet, and lifestyle - dont these factors play a significant role in determining the effectiveness of fasted Zone 2 rides? And how do we even define optimal frequency in this context - is it based on subjective measures like perceived exertion and recovery, or are there concrete physiological markers that we should be tracking?
Its also interesting to note that many of the advocates for fasted Zone 2 rides seem to be cherry-picking data from studies that involved highly trained athletes, and extrapolating those findings to a broader population of cyclists who may not have the same level of physical adaptation. So, can we really say that fasted Zone 2 rides are a viable training strategy for everyone, or are we just seeing a classic case of survivorship bias at play here?
And lets not forget about the issue of consistency - is it better to do one or two fasted Zone 2 rides per week and stick to it, or is it more effective to mix things up and incorporate some variability in your training? And what about the role of nutrition and recovery - do these factors play a significant role in determining the effectiveness of fasted Zone 2 rides, or can we just ignore them and focus on the ride itself?
Lastly, has anyone actually done a proper cost-benefit analysis of fasted Zone 2 rides, or are we just assuming that the benefits outweigh the potential drawbacks? What about the potential risks of dehydration, bonking, and decreased immune function - are these risks being overstated or understated, and how do they impact the overall calculus of whether or not to incorporate fasted Zone 2 rides into your training regimen?
