（スポーツをした後）疲れたねって英語でなんて言うの？

Exhausted- very tired

Pooped- very tired (informal)

That was a great game but I am pooped! How about you?

How about you? - asking how the other person is feeling.

That was a great game! Are you as tired as I am?

Another way to say you are tired and also ask if the other person is also feeling the same way.

When you want to ask someone if they are as tired as you are when you're playing a sport together; then you may ask in the following ways:
-Aren't you tired? I know I am.
-I'm so tired, aren't you?
-I'm exhausted now. Aren't you tired yet?

These are all ways of saying you are extremely tired.

"I'm wrecked" or "I'm jaded" are phrases that I have only ever heard in Ireland, so maybe they are part of Irish slang.

"Worn out" means that you can't physically do another thing. It can also be used to describe an object like a mattress or a pair of shoes.

"Absolutely shattered" also conveys that you are no longer able to continue doing whatever it was you were doing that made you tired. If you can imagine a mirror that is shattered, it is impossible to do anything with it. In the same way, this is how we feel if we are overtired

Are you tired after all this exercise? I am spent! I am truly dog-tired after this game. Are you exhausted as well?

"I'm" referring to myself and this is a shorten word meaning I am
"So" really emphasising the feeling
"Exhausted" showing that the person is really weak with little energy

Exhausted' is to be extremely tired, to the point of collapse but is often used to emphasize being tired after something strenuous.
To say something was 'tough' implies it was not easy and took a lot of effort.
To be 'worn out' means you have no energy left.
Other words which mean the same are: drained, beat and knackered,

If you want to express that after playing sports that you are tired, you can use any of these expressions:-

1. I'm exhausted
   Example:- Johnny, did you enjoy the sports day today?
   Yes I had so much fun, but now I'm exhausted!

2. I'm so tired
   Example: Lisa, you won so many gold medals at sports day today.
   Yes I did! but now I am so tired.

   3.I'm burnt out.
   Example: John, you look so tanned, you must have had a great time at sports day today?
   Mandy, yes I really did! but now I am so burnt out!

The adjectives tired, fatigued and exhausted are all synonyms of each other and can be used interchangeably to express that you feel tired or exhausted after playing works or doing something active.

Example dialog :
Doug - That was a good game, I'm really tired. You?
Bobby - Yeah, good game. I agree, I'm really exhausted as well.
Doug - Well hopefully if we keep practicing with each other we won't feel as fatigued in the future.
Bobby - Agreed!

In American English, the phrase "pooped" means that you are really tired. This is a very informal phrase so it's good to use with friends but not in a professional situation. I hope that this helps. :)

After playing sports with someone, you want to say something like, "I'm so tired, aren't you?"You want to know what to say.
If you are shattered you are really tired.
To be done in means to be 'killed' - or, in this case, extremely tired (so you may look like a dead person).l

I am shattered, aren't you?
I am knackered, aren't you?
I am exhausted, aren't you?

I think shattered and knackered are incredibly British words, and exhausted is much more universal. Of course, you can drop the question tag, and just say them each as a statement.

I hope this helps.
Have a great day.
