# Help needed with V02Max/Watts required.

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.

The formula is very interesting! I also wanted to calculate my indicators for a long time!
