Why are my muscles rigid? Introduction

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.

According to the UK's Office for National Statistics the UK  economy loses almost 31 million work days per year which costs the UK economy £14 billion to bad backs, neck & other muscle problems.  A bad back is of the most common causes of absence and 80% of p will suffer with people will experience back pain at some point in their lives.  At Vitality Therapy we find back pain is something we treat on a regular basis. I know a lot of my clients and potential clients are interested in what the latest scientific research is on how effective massage is for treating back pain, becuase they don't want to waste their time and money if massage isn't going to help them. Until now scientific studies of the effectiveness of massage were conducted in controlled research situations.  However in a recent study, a physician sent patients to a massage therapist.  The massage therapist designed and provided a series of 10 massage -- at no cost to the patient -- in a clinical treatment environment.  This clinical treatment environment mimicks the experience of people who choose to seek massage in the real world. More than 50 percent of those who participated in the study experienced clinically meaningful improvements in their low back pain.  The reasearches concluded that the study gives primary care providers (i.e. GPs) the confidence to tell patients with chronic low back pain to try massage, if the patients can afford to do so.
