Factors that contribute to Muscle Cramps
I know those of you that have had a muscle cramp or spasm may be fearful of it reoccurring. So I know what to explore some of the contributing factors to muscle cramps. The aim of this is by minimising the contributing factors you will reduce the likely hood of getting muscle cramps.
Dehydration
Muscle cramps commonly coincide with dehydration. So good hydration before, during and after exercise is important, especially if the exercise exceeds one hour. So how much should you drink? Hydration guidelines are personal but the goal is to prevent excessive weight loss i.e. >2% of body weight. You can weigh yourself before and after exercise to see how much fluid you have lost through sweat. One litre of water weight 2.25 pounds. Depending upon on the amount of exercise, temperature, humidity, body weight and other factors you can loose anywhere from 0.4 to 1.8 litres per hour. A good rule of thumb is to always drink enough fluids so that your urine is clear, pale yellow & copious.
Electrolytes
Sodium & potassium are the major components of sweat. So anyone who exercises hard for more than four hours in heat such as marathon runners, triathletes, tennis players etc should replace the lost electrolytes. While a lack of sodium and potassium may contribute to muscle cramps, it should be noted that a potassium deficiency is unlikely as your body contains more potassium than even a marathon runner might lose during a hot, sweaty race. However you can rule out this as an issue by eating potassium rich foods such as bananas and oranges on a daily basis. Replacing the sodium lost during sweaty exercise is vital and this can be done by having an endurance sport drink or a salty snack.

Is a 15 minute Neck & Shoulder Massage beneficial?
Fifteen minutes is a very short space of time, so I am often asked by potential clients if they will receive any benefits from such a short massage. Well the good news is that you do receive benefits, and its not just me saying that, or the subjective experience of other clients there is scientific evidence too.
- In 1996 Shulman, K.R. & Jones, G.E. in the Journal of Applied Behavioural Science, looked at the effectiveness of chair massage in reducing anxiety in an organisation. An on-site chair massage therapy program was provided to reduce anxiety levels of 18 employees in a downsizing organization. 15 control group s participated in break therapy. Subjects’ stress levels were measured with the State-Trait Anxiety Inventory, which was administered twice during pretest, post-test, and delayed post-test to achieve stable measures. The study concluded that significant reductions in anxiety levels were found for the massage group. 1
- In 1996 Field, Ironson, Pickens et al. in the International Journal of Neuroscience concluded that chair massage therapy offers benefits in not just alleviating the physiological effects of anxiety, but also in improving mental alertness.2
- In 1997 Cady et al. in Perceptual & Motor Skills evaluated the effectiveness of a 15 minute chair massage on reducing stress as indicated by blood pressure. 52 employed participants' blood pressures were measured before and after a 15 minute massage at work. Analysis showed a significant reduction in participants' systolic and diastolic blood pressure after receiving the massage. High Blood pressure is associated with anxiety and stress, this study supports the conclusion that chair massage is relaxing and reduces stress. 3

Muscle Cramps Summary
Muscle cramps are painful, a great nuisance but they are a benign condition. (see what are muscle cramps). Their importance is linked to the discomfort and inconvience they cause. Their exact cause is unknown, (see what causes muscle cramps) although they are more likely to occur as we get older and some people are predisposed to getting them. The following contribute to muscle cramps
- Muscle fatigue
- Anything that impairs circulation
- Nutritional factors (see contributing factors & more contributing factors)
- Pregnancy (see muscle cramps in pregnancy)
