They occur mostly in longer muscles that span two or more joints. Once experienced, athletes may continue to cramp unless adequate rest is provided.

Exercise-associated muscle cramps do not have a relation with body temperature and do not recover with an external cooling modality, like an ice pack. If the theories of muscle cramps do not interest you, skip to the last part where you can learn how to deal with muscle cramps. One of the oldest theories is based on dehydration and electrolyte imbalance that occurs during exercise.

We can all agree on the importance of water in our bodies. Having an adequate level of hydration ensures optimum operation of the various systems of the body. Water content is also important for physical and mental performance in sports. Excessive water loss through sweat is very common in athletes, especially in endurance sports. Hence, every athlete, professional and recreational should be aware of this aspect of sports physiology. A dehydration of even 2% has been shown to significantly compromise physical performance and work capacity. This applies not only for endurance events like the marathon, but also for activities requiring strength, power, and high-intensity endurance. Dehydration has also been linked with impairing mental functions like attention, working memory capacity, reaction time, coordination, decision-making, and mood. The effects are experienced differently based on ethnicity, level of fitness, gender, previous hydration levels, and individual adaptation to environ...
