That depends on which dictionary you cite. Here's Webster's:

vi·tal·i·ty

noun


 * a lively or energetic quality


 * the power or ability of something to continue to live, be successful, etc.

a :  the peculiarity distinguishing the living from the nonliving

vig·or

noun


 * strength, energy, or determination

1 active bodily or mental strength or force

2 active healthy well-balanced growth especially of plants

3 intensity of action or effect :  force

But I'm not looking at dictionary definitions for appropriate verbiage. I'm looking at the terms and definitions that RPG's have set throughout gaming history. And most RPG's use vitality, constitution, or stamina to determine health, but in cases where vitality and stamina/vigor have both existed in the same game, vitality is usually what determines health while stam/vigor is the energy reserves.
