There's no support for any of this. Bananas are touted for preventing cramps due to the potassium. Problem is that's there's no evidence that low electrolytes cause cramping.
To the extent, cramps are associated with muscle fatigue, the carbs in the banana may help by giving you an energy source and delaying depletion of muscle gylcogen.

The water, salt, electrolyte tablet stuff is all without scientific support that it prevents cramps.
The answer is to train your body to withstand the workload.
