Plus, eat a bar of chocolate about 20 mins before u have to play (for some ENERGY
) And don't OVERPRACTISE!!!!
I would suggest you to not do your exam while you're in digestion, otherwise all the blood flow woudl be redirected to the digestive system leaving your brain and arms with les blood flow: hence spacy feeling
I wouldn't suggeste either to eat a chocolate bar, as it contains refined sugar that because of its lack of fibers cause a sugar spike raising your glycemia too quickly, resulting in a glut4 atrophy and insulin secretion redirecting too much glucose on the cell membrana and leaving your brain without a sugar supply
That would eventually result in hypoglyicemia symptoms and spacy feeling of headache or even fainting
Now, eat something sugared that is not refined and that is absorbed and supplied slosly in to the blood stream
Trail-mix 90 minutes before the exam would be good as you have the energy of carbohydrates but they're converted to glucose quickly so during your exam you will have a steady glucose supply for your brain and you won't ever run out of ATP
The night before eat light, not overdo with the fats (but get some EFA though) as you want to sleep properly and you don't need a hard digestion ruining your sleep
Have many veggies, veggies and veggies again
You want to consume fibers to have your bowel empty the next day, you want to consume minerals and vitamins so that you don't feel tired the next dat, you want to consume enough phytochemicals to help with your metabolic processes
Drink a lot of water
