Drinking 8 glasses of water a day is considered conventional wisdom that can be heard multiple times every day in settings all over the world including the MMA training scene. Much like many things concerning training, the amount of fluid intake a person should have is more individualized than just a flat prescription of 8 glasses a day. A fighter’s fluid needs are unique, and as such, need a unique approach.
Dehydration can cause a tremendous reduction in performance. If you’re dehydrated, your body and mind suffer greatly, increasing your rate of injury as well as endangering your health permanently . In the cage this is a formula for disaster. There are two major reasons why an MMA fighter has different fluid intake needs than your average person and other athletes. First is that your activity level is much higher than people taking part in many other athletics. MMA training is unusually intense long with periods of high intensity scattered throughout. There is measurably more fluid loss than a steady-state activity like jogging or running. Secondly, based on the level of conditioning required to be competitive and fit, mixed martial artists tend to have much more muscle mass than most. Glycogen , the carbohydrate being stored mostly in muscle requires a lot of water and must stay hydrated.
How Much Fluid Do I Need As A MMA Fighter?
Everyone is different making figuring out exactly how much fluid you need isn’t quite as simple as 8 glasses a day. With a little bit of calculation and a dedication to monitoring your progress; you can ensure you’re getting the right amount of fluid. Here are some general guidelines:
Before Training Hydration
• Drink at least15-20 fl oz. 2 hours before training
• Drink 8-10 fl oz. 15-30 minutes before training
During Training Hydration
• Drink 8-10 fl oz every 10 minutes
• If you’re training more than an hour and a half, drink 8-10 fl oz. of electrolyte replacement drink every 30 minutes you are training.
To assess hydration check your urine color. If it’s cloudy and yellow, then you know that you’re dehydrated. The toxins that your kidneys filter out aren’t diluted in a large enough urine volume to be invisible. If your urine is clear, you’re likely getting enough fluids.
Another way to monitor your hydration is to weigh yourself before and after your training session. The vast majority of your weight loss during a given training session is fluid. For example, if you weighted 155lbs. before your training session and weigh in at 153lbs. after your training, which means that, you lost 32oz. of fluid. (1 pound=16 ounces of fluid).
So, train hard, train smart and stay hydrated!
