What if wattage isnt the definitive measure of a cyclists anaerobic capacity that weve all been led to believe? Weve all heard the stories of riders like Bernard Hinault and Jacques Anquetil, who dominated the sport without the benefit of modern power meters and training methods. Yet, they were still able to tap into their anaerobic reserves and deliver devastating attacks in the mountains.
If we look at the physiology of anaerobic capacity, its clear that its a complex interplay of factors, including muscle fiber type, buffering capacity, and neuromuscular recruitment patterns. While wattage can certainly provide a proxy measure of anaerobic capacity, its not the only factor at play.
Consider the case of two riders with identical wattage outputs, but differing muscle fiber type distributions. One rider has a higher proportion of fast-twitch fibers, which are optimized for high-intensity, short-duration efforts. The other rider has a higher proportion of slow-twitch fibers, which are better suited for endurance efforts. Which rider is more likely to excel in an anaerobic effort, despite having the same wattage output?
Or what about the role of neuromuscular recruitment patterns in anaerobic efforts? We know that the brain plays a critical role in regulating muscle contraction and relaxation, and that riders with a higher degree of neuromuscular coordination are often able to generate more power and speed. But how do we measure this aspect of anaerobic capacity, and how do we incorporate it into our training and racing strategies?
Perhaps the most interesting question is whether wattage is even the right metric to be using when it comes to anaerobic capacity. After all, wattage is a measure of average power output over a given time period, whereas anaerobic efforts are often characterized by brief, all-out sprints. Would we be better off using metrics like peak power output, or even more exotic measures like anaerobic work capacity or high-intensity energy expenditure?
Ultimately, the relationship between wattage and anaerobic capacity is likely to be complex and multifaceted, and theres still much to be learned about how these two variables interact. So lets challenge our assumptions and explore new ways of thinking about anaerobic capacity – and how we can use wattage (or other metrics) to unlock our full potential as riders.

(Unless we're talking about Christmas decorations, then I'm all for it!)
You've got me pondering the power of the mind in cycling. Ever heard of "grinta," the gritty determination that propels riders up impossible slopes? Some say it's unquantifiable, yet it's as real as any wattage metric.
While wattage is a useful tool, it might be limiting if that's all we focus on. Incorporating sprints, high-intensity intervals, and even mental toughness drills could unlock hidden potential.
