Older adults appear to be at greater risk, especially when performing strenuous physical activities or doing unfamiliar things.

However, there is a lack of good evidence to support the link to salt deficiency in all cases, and there may be multiple causes. Vitamin E may also help to prevent cramps.

Of course, if cramps are severe, persistent, frequent, or don’t respond to simple treatments, or occur for no obvious reason, you should see your doctor.

Preventing Sports Cramps

Types and Causes of Cramps

Another explanation is that is that when muscles become fatigued they fail to respond properly to the signals from the brain. Similarly, muscle fatigue, caused by sitting or lying for a long time in an awkward position, can trigger cramps. There are many other drugs that have a similar effect.

This then increases pressure on the nerve terminals, causing pain. Even the simple stretches of the calf-muscle, done two or three times can help. Stretching, Warm-up and Cool-Down – Various sporting authorities suggest adequate stretching before and after sports or exercise as well as thorough warm-up and cool-down, to help prevent cramps during various physical activities. You cannot control the spasms in the affected muscle when it occurs. A simple way to tell if you are at risk of cramping is to look around and see if you are losing more salt than your fellow competitors, through excessive sweating. One common explanation given for why muscles cramp is that the combination of salt deficiency and dehydration causes the muscles cells to spasm and contract.

What is the treatment for skeletal muscle cramps?

Pre-exercise hydration : about 0.5 litres per hour of exercise three to four hours before the exercise.

During exercise: about 0.4 to 0.8 litres per hour for long distance runners

Post-exercise: about 0.5 litres of water for every pound of body weight lost.

Rest and Sleep Cramps – These cramps that occur at night or when people are resting are quite common, particularly in older adults. Sometimes these cramps are triggered by movements that shortens the muscle. This means eating foods with moderate salt content or high-sodium sports drinks. Muscle injuries may themselves cause the muscle to spasm.. If the cramp is due to fluid loss through sweating, fluid and electrolyte replacement is essential (sodium and potassium).

Also when sodium loss by ultra-marathon competitors was measured in a South African research study, no significant differences were found between athletes who experienced cramp, and those who did not.

Remaining Hydrated – Keeping well hydrated before, during, and after an exercise activity is important, especially for sessions longer than 60 minutes. Cramps in football players occur in both hot and cold weather, and so excessive sweating and loss of sodium seems an unlikely cause in cold weather.

Medications – Numerous medicines can cause cramps. Salt loading about eight hours before a strenuous workout or a race can help boost stores and avoid depletion.

Eventually the flood of the signals overwhelm the muscles causing spasms and leading to a cramp.

The various types and causes of cramps are outlined below:

Vigorous activity – Cramps commonly occur after vigorous use of muscles and when seldom used muscles get fatigued, immediately or sometimes many hours later. For many years, athletes were told to eat bananas when starting to cramp because bananas are rich in potassium. Fixing sodium-associated cramping is relatively easy and it can be prevented by increasing your sodium intake before, during and after workouts. Taking an extra dose of calcium before going to bed may help prevent cramps. Also the signals themselves may be blocked. Nocturnal or night cramps can be painful, disturb sleep and they can occur over and over again within one night and over several days. Depending on the type of exercise, humidity and temperature and your body weight people can lose from about 0.4 to almost 2 litres (1 pint) per hour.

Cramp frequently occurs in the calf muscle, located at the back of the lower leg, the quadriceps at the front of the legs, or the hamstrings at the back of the thigh. Gently massaging the cramping muscle will often help it to relax as well. The body over-compensates by sending more and more signals to get the muscle to do what is required.

Injury – Frequent muscle spasm may happen as a protective response because of an injury, such as a broken leg. Hot, humid days and sudden rising temperatures can trigger dehydration-based cramping. For example, pointing the toe downwards while lying in bed, contracts the calf muscle, which may start to cramp. The pain can be severe and the muscle may ‘pull’ and cause lasting pain.

Hydration recommendations

Most cramps can be relieved if the muscle can be stretched out for a minute or so. Repeating the stretching when people get up at night can also help.

Electrolyte Dehydration Muscle Cramping – Nutritional cramping is caused by electrolyte imbalance or dehydration or sometimes both. It is a good idea to take the time to weigh yourself before and after exercise to monitor how much water you lose through sweat during the exercise. Night cramps can also be prevented by taking adequate magnesium and calcium. The precise reason why night cramps occur is unknown. This includes drugs that have diuretic effects which often cause the loss of potassium, magnesium and calcium, which can also cause cramps. However studies have shown that sodium-related cramping is much more common than that triggered by potassium imbalance. The aim is also to replenish lost electrolytes, such as potassium and sodium, which are lost through sweat. Nocturnal and rest cramps can frequently be prevented by conducting stretching exercises before going to bed. When muscles deprived of water tends to cramp. The exact hydration plan will depend on the individual and should aim to now allow a weight loss greater than about 2% of body weight. Applying warmth using a heating pad or a hot bath can also be helpful. When this occurs, the spasm acts see here


Probability of Rolling Sums on a Pair of 12-Sided (Dodecahedron) Dice

The total probability of rolling a sum of 10, 11, or 12 is also 30/144. The probability of throwing a sum that is a multiple of 3 is 48/144 = 1/3 or 0.33333.

For example, the probability of rolling a sum between 5 and 9 (inclusive) is 30/144 ? 0.2083 = 20.83%. The likelihood of getting a sum between 9 and 16 is 72/144 = 1/2 = 0.5. If you look at the list of probabilities you will find many possible solutions to this problem.

When you roll two 12-sided dice, the likelihood of getting a sum of 10, 12, 13, 14, or 15 is 54/144 = 3/8 = 0.375.

Practical Example

Suppose you are designing a board game that uses two dodecahedral dice. The total probability of rolling a sum between 17 and 24 (inclusive) is 28/144 ? 0.1944 = 19.44%.. You want to find a range of sums whose total probability of occurring is about 1/5 = 20%, so that roughly one fifth of the time a certain outcome happens during the game.

With two 12-sided dice, there is no range that gives a probability of exactly 20% since the probability is always a fraction over 144, and 144 is not divisible by 5.

Other Probabilities

The chances of rolling an even sum are exactly 72/144 = 1/2 = 0.5, as are the chances of rolling an odd sum see here
