It doesn’t take many classes to realize that Krav Maga training is a very high-intensity activity. Without proper nutrition prior to class — and many times, boosts of energy during class –it is all too easy to “bonk”, or “hit the wall”. This is when your body is out of energy reserves (stored in the form of glycogen in your muscles and liver), resulting in dizziness, fatigue, and a host of other unpleasant symptoms.
As I’ve mentioned in the past, I like hitting up one of my special oatmeal concoctions a few hours prior to training or sparring. There are a lot of other great choices to be had as well, the best of which have a good balance of complex sugars, protein, carbs, and fiber. This is pre-training nutrition and is pretty straight-forward as you don’t have to rush to eat it, aren’t jittery from adrenaline, and don’t have to fish it hastily out of your bag between drills, etc. — unlike your nutrition during your training. It will keep you going through a 1 to maybe 2 hour class, though you will likely begin “feeling the deficiency” into that second hour. (more…)
