More factors that contribute to muscle cramps
Previously I discussed how dehydration & lack of sodium or potassium may cause muscle cramps. I now want to explore other nutritional factors.
Calcium
Calcium plays an essential role in muscle contractions. Some active people report their problem with cramping disappears when they boost their calcium intake. This anecdotal evidence is disputed by scientists who state that when dietary deficiencies of of calcium occur, calcium is released from the bones to provide what the body needs for proper muscle contraction. If you are plagued by muscle cramps, it may be worth trying to increase your intake of dairy or other calcium rich foods to see if it helps.
Magnesium
Just as muscles need calcium to contract they need magnesium to relax. Roffe et al demonstrated that magnesium helps reduce leg cramps that occur in the middle of the night.

More tips on how to prevent Delayed Onsite Muscle Soreness
Previously I have explained what DOMS is, and why it plagues some people and not others and given you some ideas on how to prevent it. Given DOMS can be so debilitating and demotivating I wanted to give you more tips on how to prevent DOMS. 1. Omega 3 Fatty Acids Omega 3 fatty acids, like those found in fish and flax oil, are a fantastic addition to your recovery arsenal. Your body can’t make them, so you have to eat them, they are found primarily in fish and wild game, and to a lesser degree in certain nuts and seeds. They are powerfully anti-inflammatory and pro-recovery, and are protective to connective tissue, nerve tissue, and muscle tissue. 2. Protease Enzymes A study by Innerfield in 1957 showed that protease enzyme supplementation may have anti-inflammatory effects, and others have shown them to be specifically effective at reducing DOMS. Protease enzymes include trypsin, bromelain, chymotrypsin and papain, and they help modulate the pro-inflammatory response by blocking pro-inflammatory prostaglandins and stimulating anti inflammatory processes. If you go this route, make sure you get a formula that includes that piperine. This is an ingredient extracted from pepper that increases enzyme absorption by up to 60%. You need this boost because enzymes don’t absorb that well in the gut. 3. Compression Tights Research found that marathoners who wore compression gear in the 24 hours after a race reported less soreness. The technical fabric supports muscle groups, reducing movement, which can result in less soft tissue damage. Compression can also boost circulation. However, to ensure the right level of compression, you’ll have to work out the size you need using your height and weight. 4. Foam Roller Most people are familiar with foam rollers and know that using it on sore muscles can alleivate the pain. Remember using a foam roller may be painful and shouldn't be unbearable. Personally I prefer receiving massage to foam rolling my own sore muscles. Both sports and deep tissue massage can help alleviate DOMS too. References
