Stamina is your endurance. For example, the more you run, the longer your stamina will be. It relates to fitness because the more stamina you have, the longer you'll be able to participate in athletic activities.
Stamina is your ability to withstand physical and mental effort. For example, athletes have very good physical stamina as they are able to compete in sports for very long periods of time. Other people might do very well in long exams as they have good mental stamina. If you have bad stamina, you might find yourself getting tired quickly as the result of straining yourself either physically or mentally.
There is no adjectival form of the noun stamina. You would have to recast your sentence. For example:'My friend had enormous stamina when she was running the marathon.''I have noticed that David's stamina has decreased over the past few months.'If you are taking the word stamina to mean high stamina (as opposed to being just a neutral synonym for staying-power, with no indication of how much of it the person in question has), and you want an adjectival equivalent, you could perhaps use powerful or energetic, although they are not exact synonyms.
they are both the same thing for the most part, its just that the definitions are worded differently. stamina is how far you can go physically while endurance is how much you can do. if you were to use running as an example, your stamina would be how far you can run and your endurance is how long you can go without getting tired.
