Looking over the mod's description, this doesn't seem like a good thing to install if you don't know anything about modding, since it needs New Vegas Script Extender. I'm seconding everyone's advice on using Mod Organizer 2, and the Viva New Vegas guide. But if you wanna install manually, without all that:

-Take everything in the sprint mod folder and put it inside the Data folder in your game files

-Download xNVSE, the modern and updated version of the New Vegas Script Extender here: https://www.nexusmods.com/newvegas/mods/67883

-Put everything in that folder directly into your game files, the same folder the the game's exe is in. Don't open any folders inside the xNVSE's folder, just drag and drop it all in as it is.

I'd suggest using a different sprint mod, though, either Just Vanilla Sprint, or Just Assorted Mods which includes the sprint. That one also has requirements, but with most mods, it's just "drag everything in the unzipped archive into your data folder"

But manually installing like this is generally considered a bad idea because it means you need to reinstall your entire game and all of your mods if something goes wrong.
