Chronic IT Band Syndrome or Something Else?

April 29, 2013 by Dr. Dino Pappas The weather is warming up and out comes the endurance athletes (runners, bikers and triathletes) again.  The old aches and pains re-emerge.  An endurance athlete that can’t participate in their sport anymore is kind of like a dog owner that’s lost their dog (depressed).  For more on that […]

Cross-talk between skeletal muscle and immune cells: muscle-derived mediators and metabolic implications

Pillon NJ,et al. Am J Physiol Endocrinol Metab. 2013 Mar 1;304(5):E453-65. doi: 10.1152/ajpendo.00553.2012. Epub 2012 Dec 31. Abstract Skeletal muscles contain resident immune cell populations and their abundance and type is altered in inflammatory myopathies, endotoxemia or different types of muscle injury/insult. Within tissues, monocytes differentiate into macrophages and polarize to acquire pro- or anti-inflammatory […]

Origin and Development of Muscle Cramps

Marco Alessandro Minetto, Aleš Holobar, Alberto Botter, Dario Farina Exerc Sport Sci Rev. 2013;41(1):3-10. Abstract and Introduction Abstract Cramps are sudden, involuntary, painful muscle contractions. Their pathophysiology remains poorly understood. One hypothesis is that cramps result from changes in motor neuron excitability (central origin). Another hypothesis is that they result from spontaneous discharges of the […]
