Low Sodium Levels
In our society, where so many foods are high in salt, sodium tends to get a bad reputation. However, sodium is an essential mineral that contributes to the regular balance of water in the body and helps maintain heart rhythm. Another function of sodium is that it’s essential for muscle contraction.
While a diet low in sodium could result in an imbalance and cause leg cramps, those most likely to suffer this symptom due to low sodium levels are people who exercise for several hours at a time. The risk of developing muscle cramps due to reduced sodium levels increases when you sweat excessively for long periods of time.
If you fall into this category, your leg cramps can be reduced or eliminated by consuming more salt, be it electrolyte drinks during training or drinking soup broths on training days.
