Reducing Muscle Soreness with Berries

The burning sensation during strenuous exercise may be related to the build-up of lactic acid in our muscles (see Reducing Muscle Fatigue with Citrus), but that’s different than the delayed onset muscle soreness that occurs in the days following a bout of extreme physical activity. This post-exercise soreness is thought to be due to inflammation caused by muscle cell damage (little micro-tears in the muscle).

If it’s an inflammatory reaction then might anti-inflammatory phytonutrients help? The bioflavonoids in citrus might help with the lactic acid buildup, but we may need to ramp up to the anthocyanin flavonoids in berries to deal with the inflammation.

We know, for example, that if you eat about 45 cherries a day you can significantly reduce the levels of inflammatory markers like c-reactive protein in your bloodstream. Mushrooms (Boosting Immunity While Reducing Inflammation), nuts (Fighting Inflammation in a Nut Shell), and purple potatoes (Anti-Inflammatory Effects of Purple Potatoes) may also reduce inflammation (along with plant foods in general, see Anti-Inflammatory Antioxidants and Aspirin Levels in Plant Foods) so much so that plant-based diets can be used to treat inflammatory conditions. See, for example, Dietary Treatment of Crohn’s Disease, Diet & Rheumatoid Arthritis, and Potassium and Autoimmune Disease. Animal products on the other hand (paw?), may increase inflammation through a variety of mechanisms, including endotoxins (How Does Meat Cause Inflammation?), arachidonic acid (Chicken, Eggs, and Inflammation), and Neu5Gc (The Inflammatory Meat Molecule Neu5Gc).

But what about reducing muscle soreness?

If you take some guys and make them flex their biceps against way too much weight over and over and over again, the next day the strength in their arms is way down—about a 30% drop—and man are their arms sore! But if they were drinking some cherry juice their arms ended up hurting less—and they were able to better preserve their strength. Why not just feed them cherries? Because you can’t do a placebo group since you can’t really create a convincing fake cherry, but you can make fake cherry juice in the form of cherry Kool-Aid.

This was the first study to examine the effect of the consumption of any cherry product on the symptoms of exercise induced muscle damage, and it seemed to work (see the above video). Follow-up studies show it also works on reducing muscle pain in long-distance runners (speeding recovery after a marathon), and, as we know, “Optimizing recovery from exercise is the holy grail of exercise science.”

A similar study showing anti-inflammatory effects of eating blueberries took it a step further and actually paid athletes to take a muscle biopsy so they could see what’s happening to their muscles on a microscopic level.

It’s like another study showing massage could decrease inflammation. At first I was like: “ooh, I wouldn’t mind being part of that study—free relaxing massage!” until I read the protocol: you got to rest a few minutes, then the scalpels come out and cut out some muscle samples. No thanks.

And of course there are drugs—there are always drugs—but with drugs there are side effects. So the cherry study, as noted in an editorial comment, “may provide more of a sensible and realistic treatment option for those suffering from sore and damaged muscles. The scientific question of how to treat the damaged muscle is an important one, and these researchers should be applauded for finding a potential treatment that is not only practical, but one that can be enjoyed.”

How about improving athletic performance more directly? See my video series on performance-enhancing vegetables described in my blog Using Greens to Improve Athletic Performance.

Intriguing! I must try this. Maybe it will work for CFS as well.
