Background and Objectives: Muscle injuries in professional cyclists have always been one of the issues that sports science researchers have sought to find appropriate solutions to prevent. The aim of this study was to evaluate the effect of a grueling exercise session with MPC supplementation on muscle injury indices in young cyclists.
Materials and methods: The research method was quasi-experimental and the research design was cross-sectional in which 20 professional cyclists with a history of championship in the province and the country were studied by convenience sampling in two groups of supplement and placebo. Participants in the supplement group consumed 400 mg of solution containing MPC powder per kilogram of body weight with 400 cc of water, and participants in the placebo group consumed a solution containing maltodextrin powder (100 mg per kg of body weight) and a second blood sample was taken. It was done one hour after taking the supplement. In the next step, after 10 minutes of warm-up, the Wingate test was performed and blood samples were taken 24 and 48 hours after the test. Analysis of variance with repeated measures at the significance level of P ≥ 0.05 was used to test the data.
Results: Findings suggested that a grueling workout session with MPC consumption had no significant effect on creatine kinase index (p = 0.126) and lactate dehydrogenase (p = 0.526) Creatin kinase level of professional cyclists after 24 Hour and lactate dehydrogenase Professional cyclists reached their highest level of rest after 24 and 48 hours of strenuous activity, respectively.
Conclusion: In general, it can be concluded that a grueling session with MPC supplementation has no significant effect on muscle injury indices in young cyclists. Therefore, other nutritional recommendations and strategies can be offered.
Keywords: Exhaustive training, MPC supplement, muscle injury indicators.
