So I recently noticed that only after a few sim minutes of doing activities like playing soccer and similar Freetime activities, a sim's energy and hygiene will tank dramatically, making the activity pointless.

I googled a mod for this and a few of Cyjon's mods came up but I wasn't sure which one actually prevented this from happening if any at all. If someone could direct me towards a mod that prevents a sim's needs from tanking dramatically when doing these activities, I'll be highly grateful!

You must understand that exercising makes sims sweat so hygiene drop is normal. For energy drop is this one: http://www.cyjon.net/node/231

That's understandable, it' was more the dramatic energy drop that bothered me. But thank you for this link!
