Its astonishing how many people blindly advocate for Zone 2 training as the holy grail for endurance athletes, claiming that its the key to unlocking improvements in maximal cardiac output. However, after delving deeper into the research, Im starting to question the validity of these claims.
Is it really true that long-term Zone 2 training significantly enhances maximal cardiac output, or are we just assuming this based on outdated studies and anecdotal evidence? If so, what are the exact mechanisms by which this occurs?
Some studies suggest that prolonged periods of Zone 2 training can lead to cardiac fatigue, decreased stroke volume, and reduced cardiac output at high intensities. Others propose that its the duration, frequency, and consistency of Zone 2 training that matters, not the intensity itself.
Furthermore, what about the role of high-intensity interval training (HIIT) in increasing maximal cardiac output? Do we really need to spend hours slogging away in Zone 2 to see improvements, or can HIIT protocols achieve similar, if not better, results in a fraction of the time?
Lastly, how do individual differences in cardiac function, genetics, and training experience influence the effectiveness of Zone 2 training on maximal cardiac output? Are we oversimplifying the complexity of this relationship by making blanket statements about the benefits of Zone 2 training?
Its time to reexamine the evidence and challenge the conventional wisdom surrounding Zone 2 training. Can we really say that its the best way to improve maximal cardiac output, or are we just following a outdated dogma?
