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.

Heel Pain – Part 2 – Grumbling Achilles Tendon
Last week I discussed Plantar Fasciitis one of the major causes of heel pain, this week I am going to discuss a grumbling achilles tendon, or to be technically correct, non-insertional Achilles tendinopathy, he other major cause of heel pain. Although a rupture of the Achilles is well known, it is actually more common to have what is known as a grumbling Achilles. The pain is felt at the back of the heel above where the Achilles tendon joins the bone. It feels stiff and swollen, particularly in the morning and can prevent the sufferer from taking part in sport. Sometimes the pain is lower down where the tendon joins the bone. How can I tell if my heel pain is a grumbling achilles tendon? You may have swelling over or either side of your achilles tendon which runs from your heel to your calf muscles. The skin over the achilles tendon may be red and/or hot. If you sit down with your feet on the floor and raise your foot, as you use your achilles tendon you may hear a crackling sensation. What causes a grumbling achilles tendon?
- The tab on your shoe rubbing against your achilles tendon.
- Failing to warm up properly before playing sports.
- Over use of the tendon from intensive training, e.g. running
- Scar tissue from a previous injury.
- High impact on hard surfaces e.g. any sport where you jump or tennis.
