You’re a Pro Athlete: How Much Water Should You Drink?


You’re a Pro Athlete: How Much Water Should You Drink?Most of our readers probably aren’t starting for the New England Patriots or spending their days training at a FIFA football pitch. But even if you’re not a professional athlete, any form of exercise takes its toll on your body.

As the amount of exercise in your daily routine increases, so does your body’s demand for fluid. That whole “eight glasses a day” mantra is woefully inadequate for people who maintain their physique and make their living as an athlete.

Using Pelican Water’s recently unveiled hydration calculator let’s determine how much water the world’s most famous athletes should be drinking during the season. The results may surprise you, and inspire you to reach for a delicious glass of filtered water.

Rob Gronkowski

This tight end for the New England Patriots is one of the most-respected players in the NFL. A dream acquisition for fantasy football players everywhere, Rob Gronkowski’s daily physical exertion could be described as “relentless.” Let’s input his information in the hydration calculator.

First, “Gronk” weighs 265 pounds and measures 6 foot 6 inches in height. Did you know that this legendary player is only 28 years old? Based on our calculator let’s set his amount of exercise at the maximum, 2 hours per day. And in terms of intensity level, we’re pretty sure the NFL qualifies as “rigorous.”

Seems like a professional American football/NFL player like Rob Gronkowski needs to drink 196 ounces of water per day to stay properly hydrated. That equals 24 cups! 24 cups is much more than the colloquially common 8-glass average.

Lionel Messi

This Argentine professional footballer (or “soccer player,” as we say in the states) is a forward for FC Barcelona. This type of football requires an extraordinary amount of cardiovascular exertion to be in what Forbes describes as “a class of [his] own.”

So let’s turn to the hydration calculator. Lionel Messi is 30 years of age, measures 5 foot 7 inches in height, and weighs approximately 160 pounds. Again, for our purposes we’re going to max out the calculator, setting his amount of exercise per day at 2 hours and his intensity level as “rigorous.”

Here’s a fun coincidence – since both of the men here exert a tremendous amount of energy during the day and are about the same age, Lionel Messi’s hydration calculation also comes out at 196 ounces, or 24 cups. You may have assumed he would need less due to his reduced height and weight, but body mass is less important than level of exercise.

Melissa Mayeux

Let’s change things up: Melissa Mayeux is a professional baseball player in France who never fails to impress as a starter for the Montpelier Barracudas (a top-division team in France). Perhaps her stats will yield a different result.

After inputting her gender we finish off with rest of her information: she’s only 18 years old (!), weighs 125 pounds, and measures 5 foot 6 inches in height. We will also input 2 hours as her amount of exercise, but will decrease the intensity level to “moderate,” as there’s much more physical downtime in baseball.

Now we see a different result: 112 ounces, or 14 cups of water per day. This change is likely connected more with the intensity level of the exercise, but also may be slightly due to Melissa’s age and smaller size. However, even 14 glasses of water per day is much higher than most people would drink.

Athletes and people who exercise regularly need to drink plenty of water throughout the day to perform their best. Calculate your approximate ideal hydration level here.
