Is there a low magnesium epidemic?

Previously I have explained what DOMS is, and why it plagues some people and not others and given you some ideas on how to prevent it.  Given DOMS can be so debilitating and demotivating I wanted to give you more tips on how to prevent DOMS. 1. Omega 3 Fatty Acids Omega 3 fatty acids, like those found in fish and flax oil, are a fantastic addition to your recovery arsenal. Your body can’t make them, so you have to eat them, they are found primarily in fish and wild game, and to a lesser degree in certain nuts and seeds.  They are powerfully anti-inflammatory and pro-recovery, and are protective to connective tissue, nerve tissue, and muscle tissue. 2. Protease Enzymes A study by Innerfield in 1957 showed that protease enzyme supplementation may have anti-inflammatory effects, and others have shown them to be specifically effective at reducing DOMS.  Protease enzymes include trypsin, bromelain, chymotrypsin and papain, and they help modulate the pro-inflammatory response by blocking pro-inflammatory prostaglandins and stimulating anti inflammatory processes.  If you go this route, make sure you get a formula that includes that piperine. This is an ingredient extracted from pepper that increases enzyme absorption by up to 60%.  You need this boost because enzymes don’t absorb that well in the gut. 3. Compression Tights Research found that marathoners who wore compression gear in the 24 hours after a race reported less soreness. The technical fabric supports muscle groups, reducing movement, which can result in less soft tissue damage. Compression can also boost circulation. However, to ensure the right level of compression, you’ll have to work out the size you need using your height and weight. 4. Foam Roller Most people are familiar with foam rollers and know that using it on sore muscles can alleivate the pain.  Remember using a foam roller may be painful and shouldn't be unbearable.  Personally I prefer receiving massage to foam rolling my own sore muscles.   Both sports and deep tissue massage can help alleviate DOMS too.

I know that I often say that one of the benefits of massage is that it may reduce anxiety.  I think most people would agree that being in hospital or undergoing hospital procedures may makes us feel anxious.  So I was interested in a recent study that looked at the effectiveness of massage with or without guided imagery (a therapist talking you through a scene to help you relax), prior to cardiac catheterisation.  As you can imagine anxiety is very common in patients prior to cardiac catheterisation, which can lead to high blood pressure and increase the amount of sedation necessary to complete the procedure. Fifty five patients opted to receive either a 15-minute massage (31 patients) and a 20 minute guided imagery (24 patients) in a quiet area of the hospital prior to cardiac catheterisation.  Self-report anxiety levels, blood pressure and heart rate were evaluated in the research participants as well as matched for comparison to a control group not taking part in the study. The results indicated that massage, with or without guided imagery, produced significant reductions in self-reported anxiety, with the combined intervention having a more pronounced effect.  In addition a lower diastolic blood pressure and heart rate were found when compared to the control group. In my experience slow, deep stokes help to reduce anxiety and as a team we often incorporate this into treatments.

In part 1, I looked at the impact of sitting on your muscles,  and in part 2 I started to explore the impact on the rest of your body.  In this post I continue to explore the impact of sitting on your circulatory system including your heart. Heart Disease When sitting for prolonged periods of time, muscles burn less fat and blood flows more sluggishly, allowing fatty acids to more easily clog the heart.  In 2012 Ford & Caspersen in their research paper, Sedentary behaviour and cardiovascular disease: a review of prospective studies (International Journal of Epidemiology, Vol 41, No 5 pages 1338 - 1353) showed that the people with the most sedentary time are more than twice as likely to have cardiovascular disease than those with the least. In 2012 Zedric and Hamilton found that just a few hours sitting suppresses a gene that helps keep your cardiovascular system healthy by controlling inflammation and blood clotting.
