In part one we looked at what electrolytes are and why they are so important to the body. Here in Part 2, we look at what happens to electrolytes as you exercise, why electrolytes are important and what you can do to optimise performance before, during and after a workout.
The main reason why electrolytes are lost during exercise is via the water lost through sweating. As a rough guide, you tend to lose about one litre of water per hour of exercise.
