Is interval training still a viable method for improving power output in road cyclists, or has the rise of more nuanced training methods like polarized training and zone-based training made it obsolete? Ive seen plenty of coaches and experienced riders advocating for a move away from traditional interval workouts in favor of more varied and dynamic training protocols.
It seems to me that the old-school approach to interval training - 4-6 x 8-minute VO2 max efforts, 3-4 times a week - might be doing more harm than good for many riders. Not only is this type of training incredibly stressful on the body, but it also fails to account for the complexities of real-world racing and the varied demands of different courses and conditions.
Meanwhile, polarized training and zone-based training offer a more holistic approach to training, one that incorporates a wider range of intensities and workouts to build endurance, strength, and speed. By focusing on specific physiological adaptations and tailoring workouts to individual needs and goals, these methods might be more effective at producing real-world results.
But what do the experts and experienced riders think? Is interval training still a valuable tool in the quest for improved power output, or is it time to move on to more modern and sophisticated methods? Do the benefits of interval training - improved cardiovascular fitness, increased muscular endurance - outweigh the drawbacks, or can these benefits be achieved through other means? Id love to hear from coaches, experienced riders, and anyone with a strong opinion on the matter - is interval training still relevant, or is it a relic of the past?
