Effect of medicinal Plants on delayed onset muscle soreness (DOMS)
is well documented that physical exercise, particularly, intense and unaccustomed eccentric exercise is associated with muscle damage. This micro damage can change sarcomere structure and lead to muscle injury, that known delayed onset muscle soreness (DOMS). Responses of inflammatory increased due to microscopy trauma, and damage morphological ultra-structural of muscle fibers can causes pain and reducing muscle strength. These phenomena are more common in subjects that participate in sport program for the first time, or return after a gap. Some exercise that causes more muscle pain including resistance, polymeric training, skiing, downhill running and walking. Therapeutic modalities for the prevention and management of DOMS related symptoms are numerous and include, stretching, massage, compression, warm-up, ice massage, oxygen therapy, ultrasound, and exercise. One of the newest theories that clarify DOMS is inflammation theory. Based on this theory, some researcher has used anti-inflammatory storied drug such as dexamethasone, or non-storied drug such as ibuprofen, aspirin, and acetaminophen for attenuating DOMS symptoms. If anti-inflammatory drug could attenuate DOMS symptoms, therefore, theoretically, we can use plant with anti-inflammation characteristic for decreasing and attenuating of DOMS symptoms. In generally, much of plant section has anti-inflammatory property. In this regard, Chamomile plant is considered as an effective and important plant with anti-inflammation property. Chamomile plant has antioxidant and anti-inflammation compounds such as Apigenin Quercetin , terpenoid, alpha bisabolol, Coumarin, patuletin, that can attenuate pain and inflammation by reducing prostaglandin E2, interleukin 6 and factor necrosis tumor alpha concentration. Therefore, it may be used for attenuate pain and inflammation following eccentric exercise. Azarbayajani et al. reported that taking Chamomile plant for 14 day can attenuate pain and muscle inflammation during recovery phase (unpublished data). One of other plant that was used of attenuate inflammation is Cinnamon plant. In traditional medicine, Cinnamon has been used as drug for attenuate pain. Cinnamon is dried skin trunk of tree at scientific name Cinnamomum Zeylanicum. Cinnamon has compounds such as eugenol, felandren, and Safrole. Also, it has other compound such as limonene and linalool, trans Cynthia aldehyde, coumarin, resin, and phenyl propanone compound (Hydroxy cinnamaldehyde) (Maridass). Cinnamaldehyde gives property anti spasm to cinnamon plant. Eugenol can attenuate pain by decreasing inflammation via inhibiting of prostaglandins synthesis. It has been reported that taking cinnamon for two days can attenuate symptoms DOMS. In the investigation, author reported that taking Purslane for six days can decrease symptom DOMS. Regarding studies data; it seems that taking and using plant with anti-inflammation property with an appropriate method to control DOMS. However, to clarify effect of mentioned plant we need to have more studies in these filed.
