Effect of creatine supplementation on muscle damage markers and physical performance in volleyball athletes (Efecto de la suplementación de creatina sobre marcadores de daño muscular y desempeño físico en atletas de voleibol)
Year: 2020
Type: article
Abstract: Given creatine supplementation may attenuate exercise-induced damage and directly influence the ATP-CP system, the purpose of the study is to assess the effects of creatine (Cr) supplementation on muscle damage markers; creatine kinase (CK) and lactate dehydrogenase (LDH), late-onset muscle pain (DOMS) and physical performance in volleyball athletes.A controlled study with a double blind model was performed.Fourteen participants supplemented (0.3 g / kg) of creatine or placebo during (loading phase) and (0.1 g / kg) during (maintenance phase).Significant differences were observed in total plasma creatine concentration (p <0.05), body weight (p = 0.047) and lower pain perception (p = 0.020), 24 hours (p = 0.001), 48 hours (p <0.001) and 72 hours (p = 0.011) in the creatine group.The evaluation of subjective perception of pain verified a significant difference in the creatine group (p <0.05).It was concluded that creatine supplementation, associated with carbohydrate consumption, attenuated the perception of pain in volleyball players after the muscle damage protocol.
