There's this useful bunch of elements from the perodic table that muscles like - sodium (from table salt), potassium (eg from bananas), magnesium & calcium (the last 2 are often in the same supplement tablet). You don't necessarily need sports drink.

Here's a periodic table for reference. http://www.ptable.com/Images/periodic%20table.png

(One of the magnesium compounds I've tried also contains Taurine, which is just a random stimulant. I blame marketing so I don't use that one.)
