I'm 90kg atm but plan to move up to 94kg. I play as a winger, would this effect my sprinting speed?

I sprint train twice a week and do squats straight after. Surely my speed wouldn't be effected

Not at all since you do sprint training, if you did the stupid thing and just didnt do any sprint training and just took steriods to quickly build of muscle then obviously your speed would be affected. but if you build your muscle naturally and do sprint training your legs will gradually get more used to the weight the heavier you get, meaning you shudnt loose any speed and will be harder to bring down.

I doubt that we can answer this accurately. That's a 4.4% increase in mass. How that affects your speed depends on how quickly you add the mass, and how your training regime addresses the increased mass. Whether your training is sufficiently rigorous to match that increase in mass is something that only you can determine. And I mean "determine" as something that is in your control, if you understand training sufficiently to ensure that you maintain your targets. What might happen is that your initial sprinting speed can be maintained, but you find that your stamina is affected, and it is harder to maintain your speed late in the match. The difference has to do with the function called "work" (which as a physical matter always is a function of mass), not instantaneous speed. I don't see what Tuilagi's mass has to do with this fellow's speed. Mark L.

If shouldn't affect your speed at all. It will be a benefit as the heavier you are, the harder you are to bring down. I mean Alesana Tuilagi (samoan winger) is 120 kilos or summin and he's pretty quick. 94 kilos is a good weight for a winger.
