The effect of valerian extract supplementation on delayed muscle contusion following an extrovert activity session in cross-fit men

Previous studies showed that some medicinal herbs can prevent Delayed Onset Muscle Soreness (DOMS). The present study investigates the effect of valerian supplementation on DOMS elements on cross-fit men. Thirty healthy adult male crossfiters were randomly chosen and equally divided into experimental and control groups. Blood samples, Sargent jumps (SJ), and pain perception tests were measured at the starting point. The experimental group consumed (۲۰۰ mg per day ) valerian extract for two week, while the control group received a placebo. After consuming the supplementations for two week, the second samples and tests were taken. All athletes participated in the leg press eccnntric trainig(ET). Third, fourth, and fifths samples/tests were exactly executed in immediately, ۲۴, and ۴۸ hours after ET. Statistical analysis was conducted, and P≤۰.۰۵ was considered the significant level. The results showed that eccentric training induced a significant increase in the serum tumor necrosis factor-alpha (TNF-α) and creatine kinase-MB (CK-MB)Lactate dehydrogenase(LDH)C-Reactive Protein(CRP)Interleukin ۶(IL-۶) values, as well as the pain perception ،Round thigh،Range of motion of the thigh and knee in both groups. TNF-α،IL-۶ and pain perception were significantly lower in the experimental group immediately, ۲۴ and ۴۸ hours after ET. CK-MB activity was significantly decreased in the experimental group during next ۲۴ and ۴۸ hours after EC. The muscle soreness protocol and its preceding supplementation had no significant effect on SJ. The present study suggests that the consumption of valerian based on the present study dose and timespan may be effective to attenuate inflammation and pain induced by ET in men crossfit and probably has no functional impact on muscle.
