Why tennis players need electrolytes:

Five electrolytes in particular play a pivotal role in maintaining normal human muscle function: sodium, potassium, magnesium, calcium, and chloride. A shortage of any of these electrolytes will affect athletic performance through a range a subtle to serious side effects. Cramping is a common side effect of low electrolyte levels in tennis players. Replacing the full spectrum of electrolytes through a source such as SaltStick can help reduce cramping during training and performing. 

Sweat typically has about 1000 mg sodium/liter, a typical sports drink has 440 mg sodium/liter. If, during the course of training, you ingest nothing but sports drinks (or worse, water), you will become hyponatremic at some point. Many sports drinks also do not address any form of supplementation of the other key electrolytes, potentially causing yet further cramping and muscle issues.

How SaltStick can help you improve your tennis results:

What is lost in sweat should be replaced by your electrolyte capsules in a quantity and form which your body can absorb. SaltStick® Caps have been formulated to provide your body with a balanced electrolyte content in the suggested serving of 1 capsule per 30-60 minutes. Two SaltStick Caps in an hour equate to 430 mg sodium, 126 mg potassium, 22 mg magnesium, and 44 mg calcium per hour: The ideal ratio to keep you moving.
