First we must ask, "What is fitness?" Here are some definitions taken from various dictionaries. Since fitness is a state or quality of being fit, then we must define what does it mean to be fit? Here are a few definitions of fit:
•Adapted to an end or design
•Adapted to the environment so as to be capable of surviving
•Put into a suitable state: made ready
•Being in such a state as to be ready or seem to be ready to do or suffer something
•Sound physically and mentally
Now, let's take a look at the definition of a mountain. Mountains are defined as Large land forms stretching above surrounding land in limited areas, typically forming peaks and varying weather conditions.
So having mountain fitness would be defined as follows:
The ability to adapt to mountain environments so as to be capable of a high state of human performance and efficiency.
At Mountain Fitness Research, we then investigate or experiment aiming at the discovery and interpretation of facts, revision of accepted theories or laws in the light of new facts, or practical application of such new or revised theories or laws (according to Merriam-Webster) in the ability to adapt to mountain environments so as to be capable of a high state of human performance and efficiency.
