Lemme See You Sweat

“Water, water everywhere nor any drop to drink” is the quote from the Rime of the Ancient Mariner by Samuel Taylor Coleridge describing the Ancient Mariner in the early 1800’s who is stuck at sea. Many of us in Florida enjoy cycling either along A1A at the edge of the Atlantic Ocean, following the Gulf on the west coast or through routes that include views of lakes, ponds or rivers. All that water, yet not a drop to drink! Although it is important all year long to plan ahead and stash enough fluid and snacks for a long ride, it is critically important to be prepared to stay hydrated in the extreme heat and humidity of a South Florida summer.
Water is the most crucial nutrient to replenish in the heat and should be consumed just prior to exercising as well as during regular intervals while on the bike or any exercise of long duration. In addition, electrolytes and carbs need to be replenished as we sweat and burn calories. Your individual hydration and refueling needs will vary depending on many factors, including height, weight, degree of conditioning, the amount you perspire and your body’s metabolism. Humidity actually hinders the body’s ability to cool itself as it sweats and, thus, accelerates dehydration. A starting guideline would be to drink about 4-6 oz. water every 15-20 min. and consume somewhere between 30-60 g. carbs per hour. One sign of sufficient hydration is when urine passed is either light in color or clear.
Enhanced waters and sports drinks are appropriate hydration choices when exercising 60-90 min. or more to ensure the body is replacing electrolytes, especially sodium, lost in sweat. These choices may also include added potassium, an electrolyte that also plays an important role in the body’s ability to maintain proper acid-base and fluid balance, and the minerals calcium and magnesium, which are also lost in sweat. Sports drinks will also provide carbs to help the body replenish depleting glycogen stores.
Although sodium is the electrolyte we lose the most of during exercise, potassium is the electrolyte many American diets are deficient in. Any diet that is more centered on highly processed, prepackaged “convenience” foods and chain restaurant selections is likely to easily contain thousands of milligrams of sodium. The current Dietary Guidelines for Americans set the recommended daily sodium intake at 2300 mg. or the equivalent of about 1 tsp. of salt. Of course, any endurance athlete is going to take that guideline with, well…a grain of salt. However, the need for more sodium shouldn’t overshadow the body’s need for adequate potassium, as well.
The Dietary Reference Intake for potassium is 4700 mg. Potassium is fairly abundant in a diet that emphasizes fresh and dried fruits, vegetables, legumes, nuts, dairy and meat. In addition, potassium is often added in small amounts to sports drinks and to gu, gels, gummy chews and other specially formulated performance aids.
The chart, below, highlights some foods that are naturally high in potassium, as well as many other nutrients:
| Food | Portion | Potassium (mg) (approx. values) |
| Almonds | 1 oz | 245 |
| Dried Apricots | 1 oz. | 310 |
| Banana | 1 med | 420 |
| Orange juice | 8 oz. glass | 495 |
| Spinach, ckd. | ½ c. | 460 |
| Steak, top round | 4 oz., ckd. | 410 |
| Milk | 1 c. | 340 |
