Introduction to Delayed Onset Muscle Soreness

Delayed onset muscle soreness (DOMS) also called muscle fever, is the pain and stiffness everyone is familiar with after strenuous exercises.  It is noticeable worse 24 to 72 hours after exercise and it can occur anywhere in the body. However it is more memorable when it affects the lower body i.e. the legs, due to it being so inhibiting.

For a long time the cause of DOMS was thought to be the build up of lactic acid and toxic metabolic waste in the muscles.  However this theory has now been thoroughly rejected.  While the cause of DOMS is not well understood, the current consensus is that DOMS is a result of inflammation triggered by microscopic tears in connective tissues that sensitise nociceptors and heighten pain.

The pain of DOMS and the sever soreness may decrease capacity to perform in subsequent workouts.     In addition to physical symptoms for some people it can decrease motivation to exercise.   So is the pain worth the gain?   The short answer is no.  DOMS doesn’t mean you will build more muscle although it may enhance it a little.

  • Is Reiki a Placebo? – Part 1

    By nature Reiki is very intangible.   So in a series of blog articles I will try to explore how Reiki works and what the scientific research says. For me Reiki is merely a modern name for an ancient healing practice.  Which is administered by "laying on hands" and is based on the idea that an unseen "life force energy" flows through us and is what causes us to be alive. If one's "life force energy" is low, we are run down and then we are more likely to get sick or feel stress, and if it is high, we are more capable of being happy and healthy. The benefits of Reiki

    • Help some people to feel deeply relaxed
    • Help people cope with difficult situations
    • Relieve emotional stress and tension
    • Help to improve overall wellbeing
    • Help alleviate pain & anxiety
    My personal belief about how Reiki works, is that I act as a channel for Reiki energy and the client must be open to receiving it as the Reiki energy cannot “force” itself on to anyone.  As humans have free-will this means a client can block it if they consciously choose too.  The Reiki energy is then a resource that the human body can use to heal itself. So is Reiki just Placebo? A placebo is anything that seems to be a "real" medical treatment -- but isn't i.e. it is fake. The judgement is based on the availability of scientific evidence.  Dame Carol Black (– a former President of the Royal College of Physicians and of the Academy of Royal Colleges) and a group of distinguished doctors and scientists at the Kings Fund has concluded that current assumptions about what constitutes good scientific evidence for complementary therapies are too narrow. Professor Stephen Holgate who is also a member of the Kings Fund said: "As scientists, we have often sneered at the placebo effect. But as doctors, we know it can have a real impact on the outcomes of treatment for our patients. What is it, after all, but a trigger to the body's natural ability to heal itself?  That is something worth encouraging." I am a firm believer in the body's ability to heal itself.  As the aim of all complementary therapies is to stimulate the body to heal itself, they could all be considered placebo.  This is probably especially true of Reiki due to the fact that it has not been well studied scientifically.   The limited studies have not gathered enough evidence to “prove” Reiki energy exists, but this is not the same as proving it doesn’t exist. For me, it makes more sense to assess the impact of Reiki and Reiki energy.  After all if you can assess the impact of the energy then it must exist.  And as to, is it a placebo?  If the Reiki energy has an impact, it must exist, and it can’t be a placebo because its having an impact. So in my next blog I will at the scientific evidence on the impact of Reiki.
  • 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.
