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.

What causes my muscles to knot?
What are knots:
- Muscle knots are points within a muscle where contracted fibers are unable to relax.
- The dictionary is: “highly irritable localized spots of exquisite tenderness in a nodule in palpable taunt bands of muscle tissue.”
- The medical term for muscle knots is myofascial trigger points.
- Active An active trigger point or knot is one that actively refers pain either locally or via nerve pathways to another location in the body. Active trigger points are the one that clients are aware of and cause them to book to see a masseur.
- Latent A latent trigger point is one that isn’t painful until pressure is applied to it. This is when clients come to me and they find that during the massage they feel pain that they hadn’t felt before the treatment.
- Your posture
- Your potassium and calcium levels as both help to prevent knots
- Being dehydrated doesn’t help
- Your posture
- Stretching may help release knots
- To self-treat a muscular knot put a tennis ball in a sock (it makes it easier to hold on to the ball), simply place the tennis ball in the sock against either a wall or the floor and then press the part of your body with the knot on to it and move your body up and down.
- As an alternative, you could apply a deep, stroking massage directly to the muscle knot.
- The alternative is to visit a masseur.

What is the difference between sports and deep tissue massage?

- prevention of and treating sports injuries
- You work out religiously, but aren't as relgious about stretching
- You cycle or run to work and don't think to stretch
- You play sports but don't cross train so have specific trouble spots
- Your performance (in a particular sport) has dropped
- You have a history of injuries and want to reduce the likely hood of further injuries
- You work at a computer all day and your neck, shoulders & back are chronically sore
- You are so tense your back feels like concrete
- You have tired achy legs
- You are in pain
- You are stiff (or are unable to move your neck/arm/leg freely)
- You are stressed or anxious
- You have a knot or a muscle spasm
