How can I calculate the watts I would need to be able to cycle at to get a Vo2 Max test result of 42 in a maximal ramp bike test? I have just completed a sub max ramp test on the Watt Bike which gave me an estimated 38.27 V02Max. I want to reverse design my training to do intervals at the watts that would be equivalent to 42 V02 Max i.e 350watts for 2 minutes so I would then do intervals starting a 30 seconds to build up to 2 minutes.

I am 86KG, FTP of 187, Power/Kg 3.05 W/Kg. Thanks for any help.

It's worth noting that this is just an estimate and your actual watts may vary depending on various factors such as your fitness level and the specific test protocol. Additionally, to build up to 2 minutes at 350 watts you should start with 30 seconds intervals and increase gradually over time.
 
To calculate the watts you would need to achieve a Vo2 Max of 42 in a maximal ramp bike test, you can use the following formula: (Your FTP x 0.75) + (Your weight in kg x 0.0011) = Target watts.

In your case, using your FTP of 187 and weight of 86kg: (187 x 0.75) + (86 x 0.0011) = ~316 watts.

Hi. Thanks for your reply - that is exactly what I wanted to know. Can I ask about the calculation? I can't get that to work - I get 187 x 0.75 = 140.25 + (86 x 0.0011) = 140.25 + 0.0946 = 140.345. Am I missing a decimal point somwhere or something else?
 
Sorry that formula was incorrect i've deleted it from my post. Targetting around the mid 300w is about right for 30 second to 1 minute intervals though. Your ability to do them will build really fast.
 
Hey there! I'm thrilled to hear that you find the formula interesting. It's always exciting to dive into new calculations and learn more about our own performance. If you ever need any help or guidance with the calculations, feel free to ask! I've been cycling for over a decade now and have tried my fair share of formulas and indicators. So if you have any questions or need advice, just give me a shout. Keep pushing those limits and enjoy the process of calculating your indicators. Happy cycling! :)
 
Ah, the age-old question: "How can I calculate the watts for my imaginary Vo2 Max?" Well, first, you'll need to catch that elusive unicorn to power your calculator. Since you're already estimating your Vo2 Max, why not estimate your watts too? Just pick a number that makes you feel good about yourself. 350 watts sound good? Go for it! Remember, accuracy is overrated. Just ride your bike, do your intervals, and try not to topple over when you realize you're not actually as fast as you thought. ;)
 
Estimating watts for an imaginary Vo2 Max might be a tongue-in-cheek affair, but let's take it seriously for a moment. While it's true that you can't calculate watts without a power meter, you can still estimate your wattage output during various efforts. Using formulas based on your weight, FTP (Functional Threshold Power), or even perceived exertion can offer a rough idea.

However, relying too heavily on estimated numbers can lead to inaccuracies and may hinder your progress. It's essential to balance the fun aspect with the pursuit of improvement. Constantly chasing arbitrary wattage figures can lead to burnout or disappointment when reality doesn't match expectations.

So, instead of obsessing over a mythical Vo2 Max and unattainable wattage, focus on consistent training, progressive goals, and enjoying your time on the bike. Ride hard, ride smart, and remember: the real magic isn't found in watts but in the joy of cycling. ‍♀️<3
 
Absolutely, you've made some great points about estimating wattage and the importance of balancing fun with improvement. To add to the discussion, it's worth noting that while formulas can provide a rough estimate, they may not account for individual differences in pedaling efficiency, bike fit, and other factors that can impact power output.

Another approach to estimating wattage is to use online calculators or mobile apps that take into account your weight, FTP, and other variables. These tools can offer a more personalized estimate, but they still have their limitations and should be used with caution.

Ultimately, as you've said, it's essential to focus on consistent training, progressive goals, and enjoying the ride. Remember, wattage is just one metric among many, and it's not the only measure of success or performance. By keeping a balanced perspective and staying curious about the sport, we can continue to grow and improve as cyclists while keeping the joy of riding alive. Happy pedaling!
