Effect of Mulberry Juice on Blood Lactate and Creatine Kinase in Male College Soccer Players

Abstract

Abstract

            Soccer is a high-intensity endurance sport that high-intensity moments, where sprints, jumps, acceleration, deceleration, and rapid changes of direction occur repeatedly; actions related to muscle damage promotion. Indeed, these actions during a competitive soccer match promote fatigue and physiological stress in muscle tissue, excessive muscle damage, and delayed-onset muscular soreness (DOMS) in the days after the match (Mohr et al.,2016) Mulberry (Morus alba L.) contained many bioactive components such as alkaloids, anthocyanins, and flavonoids are called polyphenolic compounds (Vijayan et al.,2004; Hasimoto et al., 2008) Mulberry has been reported to protect against cytotoxicity, oxidative stress, and anti-fatigue and pro-inflammatory (Borghei and Ghazalian, 2018; Chen et al., 2017; Jiang et al., 2013) The purpose of this study was to determine the effect of mulberry juice on blood lactate and creatine kinase after high-intensity exercise. Methods: Sixteen males college soccer players of 18-25 years old participated in this study, single-blind, and placebo-controlled trial. The participants received mulberry juice and placebo juice in 2 trials before the treadmill protocol exercise. All the variables were measure before the experiment, post-high intensity treadmill protocol exercise immediately, and after 24 hours. Blood samples were analyzed for lactate and creatine kinase. Results: The results were found that significantly increased blood lactate was seen immediately after high-intensity treadmill exercise and decreased after 24 hours in the placebo and mulberry juice group (p<.01). Creatine kinase significantly increased after 24 hours of high-intensity treadmill exercise in the placebo juice group (p<.01). Conclusion: This finding suggests that mulberry juice can prevent an increase in creatine kinase after high-intensity treadmill exercise.
