Effects of 10 Weeks Swimming and Creatine Supplementation on Blood Lactate and Muscle Fatigue of Mice

Several ergogenic resources have been used by athletes to improve performance in their respective activities and succeed in their competitive events, or just with a esthetic purpose by increasing strength and rapid weight loss, a common practice in the clubs and fitness gyms. Many of these supplements promise immediate solutions for those seeking hypertrophy, decreased body fat, increase strength, endurance, and decrease fatigue. Objectives: This research study the effect of creatine on physical activity in mice submitted to swimming. And Purpose to check the potential of Creatine in the possible reduction of fatigue using an electrical stimulator and getting data from tetanus contraction through eletrofisiográficos record, Also analyze the plasma level of animal lactate as physiological assessment parameter and enhance performance predictor tool and respective differences between groups. Methods: The animals were subjected to endurance exercise training for 10 weeks, achieved through swimming sessions (30 minutes / day for three days a week, Mondays, Wednesdays and Fridays, always held in the afternoon). Results: It was observed that the creatine groups shows significantly different values when compared to the others groups. Conclusion: Concluded that creatine associated with physical training promoted better muscle fatigue tolerance and just ten weeks physical activity can improve this physical condition.
