Effects of Theobromine and Caffeine on Muscle Fatigue Levels after Maximum Physical Activity (Experiment on Male Wistar Rats)

Abstract

Muscle fatigue often occurs when a person performs a maximal activity. However, some substances are believed to be able to improve exercise performance and control energy due to muscle fatigue called ergogenic substances. Ergogenic substances that are not included in the doping category are theobromine and caffeine. Unfortunately, there are very few exercise studies examining theobromine and caffeine, so further testing to prove their benefits is still needed. Therefore, this study aims to determine the effect of the administration of ergogenic theobromine and caffeine after the maximum activity so that a decrease in lactic acid levels can be found. This research is an experimental study with laboratory testing and is carried out based on a random control posttest approach. Sampling was done by using the total sampling technique. The research sample was 18 male Wistar rats aged 2-3 months with a weight of 150-250 grams. Samples were divided into 3 groups consisting of the control group, theobromine group, and the caffeine group. The instrument for taking blood samples is accutrend plus. The data obtained were analyzed using descriptive analysis. The hypothesis was tested using One Way Anova with the help of SPSS 16. The tests carried out found that the average values of the control group, theobromine, and caffeine were 5.2, 4.9, and 4.2, respectively. The results of the hypothesis test showed that the significance value obtained was 0.35 > 0.05 which indicated that the hypothesis was rejected. In conclusion, the administration of ergogenic theobromine and caffeine did not give a significant difference in reducing lactic acid levels. This invention can thus be used as a reference for athletes not to use these substances to reduce fatigue and increase energy.

“…According to research, children with well-developed gross motor capacities do better cognitively [23]- [26]. Furthermore, education, early childhood care, and developmental psychologists agree that motor and cognitive development overlap and are interrelated [27] [57]. The correlation between motor development and cognitive development has provided support for the fundamental hypothesis of child development.…”
