Cramp is a sudden muscle pain, which is usually caused by muscle fatigue, dehydration, electrolyte imbalance and other factors. Here are some suggestions to prevent cramps:
Well-trained: Before taking part in the marathon, you should be fully trained and prepared to enhance your muscle strength and endurance and avoid muscle fatigue.
Proper warm-up: Carry out proper warm-up exercises before the competition, including easy stretching and jogging, to help muscles gradually adapt to the intensity of exercise.
Replenish water: It takes a lot of water to participate in a long marathon. Replenishing water in time can prevent dehydration and electrolyte imbalance, thus avoiding cramps.
Replenish electrolyte: electrolyte is an important component to help muscles contract and relax normally. Before, during and after the competition, properly supplementing electrolytes (such as calcium, magnesium, potassium, etc.) can prevent cramps.
Pay attention to rest: long-term exercise makes muscles tired and needs proper rest to recover. During the competition, if you feel muscle fatigue or discomfort, you should rest or slow down properly to avoid cramps.
In a word, the key to avoid cramps is adequate preparation, proper warm-up, supplementing water and electrolyte, and paying attention to rest, so as to help muscles adapt to exercise intensity and reduce the occurrence of fatigue and injury.
