Something that just came to my mind.. Are you allowed to drink pre workout, energy boost drinks, coffee, etc right before the CFA in order to increase the energy you have to do it without being completely winded? Are there are rules against it?
You CAN take a pre-workout before the test. Studies have shown that it does help aerobic and strength output, especially during high-intensity training, which is the CFA. Most pre-workouts contain Citrulline, which increases the oxygen flow to cells in your body. It helps for any medium to long-distance workouts, and most contain Beta-Alanine which, to break it down, increases your body's ability to remove lactic acid. Combined with moderate caffeine, these ingredients can help your body perform. Make sure it's moderate
caffeine. For somebody that does not regularly consume caffeine, 100-120mg of caffeine is usually sufficient for a workout. But, if you've developed a caffeine intolerance, be sure to increase your intake accordingly to reach the same effect. However, it is always best to take a break from caffeine to reset your tolerance rather than to increase your intake. Lastly, make sure your pre-workout is from a credible brand that has third-party testing. Some good pre-workouts are the ones from Optimal Nutrition and if you need more caffeine, Total War.
So, pre-workout does help. But, only take it if you use it regularly. The last thing you need during an intense test like the CFA is your new pre-workout causing a higher bpm than required for your activity, causing your body to burn more energy, and harming you in the long run.
